Abstract
OBJECTIVE To investigate the relationship between auditory-perceptual ratings of resonance and nasometry scores in children with cleft palate. Factors which may impact this relationship were examined including articulation, intelligibility, dysphonia, sex, and cleft-related diagnosis. DESIGN Retrospective, observational cohort study. SETTING Outpatient pediatric cranio-facial anomalies clinic. PATIENTS Four hundred patients <18 years of age identified with CP ± L, seen for auditory-perceptual and nasometry evaluations of hypernasality as well as assessments of articulation and voice. MAIN OUTCOME MEASURE Relationship between auditory-perceptual ratings of resonance and nasometry scores. RESULTS Pearson's correlations indicated that auditory-perceptual resonance ratings and nasometry scores were significantly correlated across oral-sound stimuli on the picture-cued portion of the MacKay-Kummer SNAP-R Test (r values .69 to.72) and the zoo reading passage (r = .72). Linear regression indicated that intelligibility (p ≤ .001) and dysphonia (p = .009) significantly impacted the relationship between perceptual and objective assessments of resonance on the Zoo passage. Moderation analyses indicated that the relationship between auditory-perceptual and nasometry values weakened as severity of speech intelligibility increased (P < .001) and when children presented with moderate dysphonia (p ≤ .001). No significant impact of articulation testing or sex were observed. CONCLUSIONS Speech intelligibility and dysphonia alter the relationship between auditory-perceptual and nasometry assessments of hypernasality in children with cleft palate. SLPs should be aware of potential sources of auditory-perceptual bias and shortcomings of the Nasometer when following patients with limited intelligibility or moderate dysphonia. Future study may identify the mechanisms by which intelligibility and dysphonia affect auditory-perceptual and nasometry evaluations.

Int J Oral Maxillofac Surg 2024; 53:677-685. [PMID: 38331640 DOI: 10.1016/j.ijom.2024.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 01/24/2024] [Accepted: 01/26/2024] [Indexed: 02/10/2024]
Abstract
The aim of this study was to compare the postoperative clinical and functional outcomes of palatoplasty with three soft palate cleft repairs and analyse the factors potentially impacting these outcomes. A retrospective analysis was conducted on a consecutive series of 337 patients who underwent primary cleft palate repair by palatoplasty modified with either Furlow Z-plasty (P-FZP, n = 77), intravelar veloplasty (P-IVV, n = 110), or combined intravelar veloplasty-Furlow Z-plasty (P-IVV-FZP, n = 150). The postoperative outcomes evaluated included wound healing (complete closure/fistula) and velopharyngeal function. Demographic and surgical data were analysed using both univariate and multivariate analysis. There was no significant difference between the groups with regard to the sex distribution, age at repair, cleft width, cleft type, or follow-up duration. However, relaxing incisions were significantly more common with P-FZP (26.0%) and P-IVV (29.1%) compared to P-IVV-FZP (10%) (P = 0.002 and <0.001, respectively). The complete wound closure rate was significantly higher with P-IVV-FZP (97.3%) compared to P-FZP (88.3%) (P = 0.012) and P-IVV (90%) (P = 0.015). The normal velopharyngeal function rate was comparable for P-IVV-FZP (86.7%) and P-FZP (83.1%), and both rates were significantly better than the rate with P-IVV (73.6%) (P = 0.039 and 0.029, respectively). The cleft type and width were identified as factors influencing postoperative outcomes. In conclusion, it may be appropriate to prioritize the palatoplasty with combined intravelar veloplasty-Furlow Z-plasty whenever feasible.

Abstract
BACKGROUND Velopharyngeal insufficiency (VPI) is a condition characterized by incomplete separation of the oral and nasal cavities during speech production, thereby leading to speech abnormalities and audible nasal emissions. Subsequently, this adversely impacts communication and potentially interpersonal social interactions. Autologous fat grafting (AFG) to the velopharynx, a minimally invasive technique, aims to improve oronasal separation by providing bulk and advancing the posterior pharyngeal wall toward the soft palate. Despite its potential, the relative novelty of AFG in treating VPI has resulted in reporting of inconsistent indications, varied surgical techniques, and mixed outcomes across existing literature. METHODS This systemic review examined the evidence of AFG for VPI treatment over the past decade (2013-2023). A thorough search across five electronic databases yielded 233 studies, with 20 meeting the inclusion criteria (e.g., utilized fat injection as their selected VPI treatment, conducted study in human subjects, did not perform additional surgical procedure at time of fat injection). Selected studies encompassed patient and surgical intervention characteristics, perceptual speech assessment (PSA) scores, gap sizes, nasalance measurements, and complications. RESULTS The majority of patients had a prior cleft palate diagnosis (78.2%), in which nasoendoscopy was the prevalent method for visualizing the velopharyngeal port defect. Fat harvesting predominantly occurred from the abdomen (64.3%), with an average injection volume of 6.3 mL across studies. PSA and subjective gap size scores were consistently higher preoperatively than postoperatively. PSA score analysis from seven studies revealed significant and sustained improvements postoperatively. Gap size score analysis from four studies demonstrated similar preoperative and postoperative differences. Complications were reported in 17 studies, yielding a 2.7% summative complication rate among 594 cases. CONCLUSIONS Autologous fat grafting has emerged as a minimally invasive, safe, and effective treatment for mild to moderate VPI. However, challenges remain because of variability in patient selection criteria, diagnostic modalities, and outcome measurements. This review underscores the need for randomized control trials to directly compare AFG with standard-of-care surgical interventions, providing more conclusive evidence of its clinical efficacy.

CLINICAL LINGUISTICS & PHONETICS 2024:1-22. [PMID: 38853471 DOI: 10.1080/02699206.2024.2355470] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Accepted: 05/10/2024] [Indexed: 06/11/2024]
Abstract
Speech training apps are being developed that provide automatic feedback concerning children's production of known target words, as a score on a 1-5 scale. However, this 'goodness' scale is still poorly understood. We investigated listeners' ratings of 'how many stars the app should provide as feedback' on children's utterances, and whether listener agreement is affected by clinical experience and/or access to anchor stimuli. In addition, we explored the association between goodness ratings and clinical measures of speech accuracy; the Percentage of Consonants Correct (PCC) and the Percentage of Phonemes Correct (PPC). Twenty speech-language pathologists and 20 non-expert listeners participated; half of the listeners in each group had access to anchor stimuli. The listeners rated 120 words, collected from children with and without speech sound disorder. Concerning reliability, intra-rater agreement was generally high, whereas inter-rater agreement was moderate. Access to anchor stimuli was associated with higher agreement, but only for non-expert listeners. Concerning the association between goodness ratings and the PCC/PPC, correlations were moderate for both listener groups, under both conditions. The results indicate that the task of rating goodness is difficult, regardless of clinical experience, and that access to anchor stimuli is insufficient for achieving reliable ratings. This raises concerns regarding the 1-5 rating scale as the means of feedback in speech training apps. More specific listener instructions, particularly regarding the intended context for the app, are suggested in collection of human ratings underlying the development of speech training apps. Until then, alternative means of feedback should be preferred.

Abstract
This article will provide an overview of how speech and resonance can be impacted in children with cleft palate. The authors will outline evidence-based assessment and treatment approaches commonly used for children with cleft palate and provide information on current initiatives to provide speech therapy. The methods discussed will be the use of telehealth to provide access to speech therapy for patients in areas without speech-language pathologists and the use of speech therapy camps to offer intensive, limited-duration speech therapy for groups of children due to the lack of trained providers in certain geographical regions.

Abstract
BACKGROUND Children with repaired cleft lip and palate may present with middle ear effusion and disturbed speech due to velopharyngeal (VP) insufficiency. Furlow Z-palatoplasty with a buccinator myomucosal flap is one of the effective surgical techniques for primary cleft palate repair and lengthening of the palate. PURPOSE OF THE STUDY This study aimed to evaluate the effect of Furlow Z-palatoplasty with buccal myomucosal flap as a primary cleft palate repair technique on the VP function during speech and the Eustachian tube function. MATERIALS AND METHODS Forty patients with non-syndromic cleft lip and palate aged 3 to 7 years surgically repaired with Furlow palatoplasty with a buccinator myomucosal flap were assessed. Perceptual speech assessment, nasopharyngoscopic examination, otoscopic examination, and tympanometry were done for all patients to assess the speech and middle ear function. RESULTS The percentage of mild hypernasality was significant in 22.5% of children with repaired cleft lip and palate, while 77.5% showed no hypernasality. Speech intelligibility was normal in 77.5% and mildly affected in 22.5% of children with repaired cleft palate. Compensatory misarticulations were recorded in 12.5% of children. Nasopharyngoscopic examination revealed adequate VP closure in 75% of children with repaired cleft palate. Twenty-five percent of children with repaired cleft lip and palate had middle ear effusion and required myringotomy with insertion of tympanostomy tubes. CONCLUSION Primary cleft palate repair with Furlow Z-palatoplasty with buccal myomucosal flap had beneficial effects on speech outcomes. It was associated with a low prevalence of middle ear effusion, and a low number of tympanostomy tubes were needed.

Comparison of intelligibility measures for children with velopharyngeal insufficiency: visual analog scale ratings, interval scales, and orthographic transcription (OT)-based measures. CLINICAL LINGUISTICS & PHONETICS 2024; 38:568-586. [PMID: 37363955 DOI: 10.1080/02699206.2023.2227987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/13/2022] [Revised: 05/17/2023] [Accepted: 06/16/2023] [Indexed: 06/28/2023]
Abstract
Regardless of the underlying cause for speech impairment in speakers with cleft palate, a universal consequence of cleft palate is reduced speech intelligibility. Still, there is no standardised approach for measuring intelligibility for speakers with cleft speech. The current study aimed to determine the relationship between orthographic transcription (OT)-based measures, interval-scale ratings, and visual analog scale (VAS) ratings for perceptual judgements of intelligibility in speakers with cleft palate as judged by speech-language pathologists (SLPs). The speaker participants were six speakers with velopharyngeal insufficiency secondary to cleft palate. Four sets of sentences from the Hearing in Noise Test were recorded from each speaker. A total of 14 SLPs provided their intelligibility judgement on these speaker's recordings by word-by-word orthographic transcriptions, a visual analog scale (0-100), and a 5-point interval rating scale. A Spearman rank correlation test indicated a negative, strong correlation between OT-based measurements and VAS scores (r = -.94; p = 0.01) and between OT-based measurements and interval rating scores (r = -.77, p = 0.01). A strong, positive correlation was found between scores obtained from VAS and interval rating scales (r = .83, p = 0.05). The strong relationship between the objective measure of intelligibility (i.e. OT-based measure) and a subjective measure of intelligibility (i.e. VAS and interval scale) supports using a less time-consuming VAS as a substitute for orthographic transcription in measuring intelligibility in cleft palate speech.

Abstract
OBJECTIVE This study investigates whether the use of acellular dermal matrix (ADM) affects the long-term speech outcomes in patients undergoing primary palatoplasty with radical intravelar veloplasty. DESIGN Retrospective cohort study. SETTING Tertiary university-affiliated hospital. PARTICIPANTS A consecutive cohort of 112 patients who underwent primary palatoplasty with radical intravelar veloplasty from August 2014 to March 2018 were included. MAIN OUTCOME MEASURES A 2 × 2 cm-sized ADM was incorporated as an interpositional graft between the oral and nasal lining at the soft-hard palate junction. The perceptual analysis of hypernasality and articulation was performed when the age of the patient reached at least 36 months. Cleft-related characteristics and surgical factors affecting the speech outcomes were investigated. RESULTS The ADM was applied in 57 patients with a mean follow-up of45.76 months (SD, 10.69), while no ADM was used in 55 patients with a mean follow-up of 48.43 months (SD, 14.98). Regarding the hypernasality outcome, 33.3% (19 of 57 patients) of the ADM group and 27.3% (15 of 55 patients) of the control group showed a greater than mild-to-moderate degree. The distribution of hypernasality and articulation grade showed no significant difference between the two groups. After controlling for potential risk factors that may affect the speech outcomes, the use of ADM showed no significant relationship with velopharyngeal insufficiency. CONCLUSION The use of ADM use in primary palatoplasty with radical intravelar veloplasty is not associated with the alteration of speech function in early childhood.

Abstract
OBJECTIVE To develop tools for predicting velopharyngeal competence (VPC) based on auditory-perceptual assessment and its correlation with objective measures of velopharyngeal orifice area. DESIGN Methodological study. PARTICIPANTS AND METHODS Sixty-two patients with repaired cleft palate, aged 6 to 45 years, underwent aerodynamic evaluation by means of the pressure-flow technique and audiovisual recording of speech samples. Three experienced speech-language pathologists analysed the speech samples by rating the following resonance, visual, and speech variables: hypernasality, audible nasal air emission, nasal turbulence, weak pressure consonants, facial grimacing, active nonoral errors, and overall velopharyngeal competence. The correlation between the perceptual speech variables and velopharyngeal orifice area estimates was analysed with Spearman's correlation coefficient. Two statistical models (discriminant and exploratory) were used to predict VPC based on the orifice area estimates. Sensitivity and specificity analyses were performed to verify the clinical applicability of the models. RESULTS There was a strong correlation between VPC (based on the orifice area estimates) and each speech variable. Both models showed 88.7% accuracy in predicting VPC. The sensitivity and specificity for the discriminant model were 92.3% and 97.2%, respectively, and 96.2% and 94.4% for the exploratory model. CONCLUSION Two predictor models based on ratings of resonance, visual, and speech variables and a simple calculation of a composite variable, SOMA (Eng. "sum"), were developed and found to be efficient in predicting VPC defined by orifice estimates categories based on aerodynamic measurements. Both tools may contribute to the diagnosis of velopharyngeal dysfunction in clinical practice.

Abstract
Surgical intervention can contribute to the development of velopharyngeal insufficiency (VPI) leading to hypernasality and regurgitation. In this case, a patient with a history of bilateral buccal flaps used for her primary CP repair presented to clinic with hypernasality and VPI as assessed by speech exam and imaging. She underwent repeat bilateral buccal flap palatal lengthening with division of the pedicles 3 months later. Three months after her division, her hypernasality score improved from moderate to mild and her posterior gap decreased. This study concluded buccal flaps can be used a second time for patients needing palatal revisions for VPI.

Abstract
This study analyzed patients undergoing multiple surgeries for velopharyngeal insufficiency (VPI) and reviewed their preoperative evaluations and techniques selected for subsequent surgeries. A retrospective chart review was performed including patients having undergone multiple surgeries for VPI at the authors' institution between 2012 and 2022. All patients were evaluated and managed at the author's institution under the direction of 4 senior surgeons. The objective of this study was to provide insight into preoperative evaluation, surgical technique selection, and other factors that may contribute to patients who require multiple VPI surgeries. Of 71 patients having undergone surgery for VPI, 8 required at least 1 additional operation for persistent VPI following the initial intervention. Six patients who initially underwent a superiorly based posterior pharyngeal flap (PPF) required additional surgery, and for those patients' subsequent operations, 5 different techniques were used throughout their treatment. Of the remaining 2 patients who had multiple VPI surgeries, 1 initially received autologous fat transfer and 1 initially underwent a furlow palatoplasty. Finally, 0 patients that initially underwent buccal flaps or collagen injection required further unplanned surgical intervention. This study demonstrates the importance of selecting an appropriate surgical approach when operating on patients following a failed VPI surgery. The algorithm developed from these findings emphasizes the importance of properly identifying the anatomical deficiency resulting from the failed intervention. A review of the advantages of nasopharyngoscopy as a preoperative evaluative technique of velopharyngeal form and function when compared to lateral barium video fluoroscopy was also included.

[PMID: 38681241 PMCID: PMC11046285 DOI: 10.1177/22925503221110066] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 12/15/2021] [Accepted: 05/02/2022] [Indexed: 05/01/2024] Open
Abstract
Objective: To determine which surgical technique offers the lowest rate of velopharyngeal insufficiency (VPI) without the need for further operative intervention, in pediatric patients with nonsyndromic submucous cleft palate (SMCP). Methods: This systematic review and meta-analysis included articles reporting on nonsyndromic pediatric patients treated surgically during childhood for SMCP, with data on postoperative speech outcomes and/or recommendations for secondary surgery. Main outcome measures included rates of unfavorable speech outcomes defined as persistent VPI requiring secondary surgery and speech outcome data. Results: 15 articles met our inclusion criteria, reporting on 383 children who underwent surgical treatment; 343 patients were included in studies reporting recommendations for secondary surgery. There was 1 randomized comparative trial, 4 comparative studies, and 10 single cohort studies. Eight articles used validated speech assessment tools. Our model showed the proportion of patients recommended for secondary surgery varied between techniques, ranging from 0.0% (CI 0.0, 1000) in pharyngeal flap to 17.8% (CI 8.9, 32.5) in straight line repair techniques, but there was no statistically significant difference between treatments (P = .33). Speech improvement ranged from 44.4% to 100%, with 9 studies recommending secondary surgery for some of their patient series. Conclusions: Although not of statistical significance, pharyngeal flap yields the lowest rate of reoperation as a primary technique for pediatric patients with nonsyndromic SMCP. Delayed repair age inherent to SMCP may render operations that rely on a functional levator muscle with less favorable outcomes. The absence of standardized surgical techniques, speech outcomes, speech therapy, and assessment make comparative analysis and recommendation difficult. We advocate for standardized speech assessment tools to improve future quantitative assessment of cleft surgery outcomes and a randomized controlled trial to better elucidate the preferred first-line technique.

Abstract
Background Shortage of speech and language therapists results in lack of speech services. The aims of this study were to find the effectiveness of a combination speech therapy model at Level IV: General speech and language pathologist (GSLP) and Level V: Specific speech and language pathologist (SSLP) in reduction of the number of articulation errors and promotion the quality of life (QoL) for children with cleft palate with or without cleft lip (CP ± L). Methods Fifteen children with CP ± L, aged 4 years 1 month to 10 years 9 months (median = 76 months; minimum:maximum = 49:129 months) were enrolled in this study. Pre- and post-assessment included oral peripheral examination; articulation tests via Articulation Screening Test, Thai Universal Parameters of Speech Outcomes for People with Cleft Palate, Hearing Evaluation, The World Health Organization Quality of Life Brief_Thai (WHOQOL-BRIEF-THAI) version questionnaire for QoL were performed. Speech therapy included a 3-day intensive speech camp by SSLP, five 30-minute speech therapy sessions by a GSLP, and five 1-day follow-up speech camps by SSLP that provided four 45-minute speech therapy sessions for each child. Results Post-articulation revealed statistically significant reduction of the numbers of articulation errors at word, sentence, and screening levels (median difference [MD] = 3, 95% confidence interval [CI] = 2-5; MD = 6, 95% CI = 4.5-8; MD = 2.25, 95% CI = 1.5-3, respectively) and improvement of QoL. Conclusion A speech task force consisting of a combination of Level IV: GSLP and Level V: SSLP could significantly reduce the number of articulation errors and promote QoL.

Abstract
OBJECTIVES The main purpose of this study was evaluation of the effectiveness of secondary furlow palatoplasty with buccal myomucosal flap (FPBF) for the treatment of velopharyngeal insufficiency (VPI) in patients with a cleft palate who were treated with two flap palatoplasty (TFP) in their primary palate repair. MATERIAL AND METHODS Twenty-three medically free children aged 4-8 years with non-syndromic and previously repaired cleft palate via TFP participated in the study. All patients received secondary surgery following the technique of FPBF. Preoperative speech evaluation was done before the secondary repair and 3 months after the surgery using a hypernasal speech scale, speech intelligibility scale, and nasopharyngoscopy. RESULTS A statistically significant improvement was observed regarding the degree of hypernasality and speech intelligibility while comparing the preoperative scores after the primary surgery to the postoperative scores after the secondary surgery. In addition, a statistically significant improvement was found in the nasopharyngoscopic assessment. CONCLUSIONS The incorporation of a buccal myomucosal flap with Furlow palatoplasty was successful in improving hypernasality, speech intelligibility, and nasopharyngoscopic scores in patients with cleft palate. TRIAL REGISTRATION clinicaltrials.gov (NCT05626933). CLINICAL RELEVANCE This technique might be the surgical technique of choice while treating patients who are suffering from VPI after cleft palate repair.

Abstract
This study aimed to introduce a surgery technique-Sommerlad-Furlow palatoplasty (SFP) and analyze the risk factors of velopharyngeal insufficiency (VPI) and palatal fistula after SFP. Cases after SFP under the age of 5 between 2011 and 2021 were reviewed, and the cases with complete follow-up information were included. Univariate and multivariate logistic regression were used to evaluate the effects of surgical age, surgery technique, surgeon's experience, and cleft type on velopharyngeal function and the occurrence of palatal fistula. SFP is a safe and effective procedure to increase the palatal length and reconstruct the levator veli palatini sling. The speech outcome after SFP was associated with cleft type and age at operation. Age = 1.285 years is the best cutoff value. The fistula occurrence was associated with cleft type only.

Abstract
This study aimed to validate the predictors of speech outcomes following Furlow palatoplasty in patients with velopharyngeal insufficiency (VPI) after primary palatoplasty and to propose and validate a model to predict the risk of persistent VPI. The study included patients with VPI after primary palatoplasty who underwent Furlow palatoplasty as a secondary surgery. Eleven variables were included: velar length, pharyngeal cavity depth, velopharyngeal gap, velopharyngeal closure pattern, sex, presence of cleft lip, existence of palatal fistula, surgeon, age at primary palatoplasty, age at secondary surgery, and time interval between primary palatoplasty and secondary surgery. Postoperative speech outcomes were assessed at least 1 year after the secondary surgery and classified as velopharyngeal competence (VPC) or VPI. Variables were analyzed using multivariate logistic regression analysis, and the area under the curve (AUC) was used to validate model accuracy. The study sample comprised 101 patients. Of the patients, 62 had VPC and 39 had VPI after secondary surgery. The results showed a younger age at secondary surgery, a smaller velopharyngeal gap, being female, having a coronal velopharyngeal closure pattern and a velopharyngeal closure ratio of 90% or greater produced a greater probability of VPC. Given the constraints of this study, it appears that the Furlow palatoplasty should be prioritized when the clinical model predicts a substantial likelihood of VPC post-surgery.

Abstract
OBJECTIVE To describe a comprehensive decision-making process for surgical correction of structural Velopharyngeal Dysfunction (VPD) following cleft palate repair and evaluate its efficacy. DESIGN Retrospective study. SETTING Tertiary care hospital. PATIENTS 300 consecutive patients with unilateral or bilateral cleft lip and palate (CLP) or isolated cleft palate (CP) diagnosed with clinical VPD following cleft palate repair between 2009 and 2014. Of these 206 patients had structural VPD and underwent surgical correction. INTERVENTIONS Surgical corrections were carried out according to the comprehensive two stage decision making process developed by the investigators. Step 1 of decision-making involved visualisation of the VP sphincter function by nasoendoscopy. This was followed by step 2 which involved per-operative identification of scarring, tissue loss, hypoplasia and other structural deficiencies in the soft palate and septal mucoperiosteum. The choice of operation was then made from a repertoire of interrelated and escalating surgical procedures consisting of palate revision and pharyngoplasties ranging from most anatomical to the least. MAIN OUTCOME MEASURES Evidence of postoperative restoration of VP function on nasoendoscopy, evaluation of speech for hypernasality, understandability, acceptability and symptoms of obstructive sleep apnea. RESULTS Complete VP closure was demonstrated in 94% of patients treated using this algorithm. There was significant improvement in all speech parameters (p < 0.00001). CONCLUSION Our comprehensive decision-making process is designed to effectively correct structural VPD according to the severity of structural and functional deficiencies in the soft palate and avoid over treatment.

Abstract
PURPOSE This study compared the interrater reliability of adult naïve listeners' perceptual assessments of different speech variables in children with a cleft palate with or without a cleft lip (CP ± L). In addition, the study investigated whether the listeners were able to perceive differences in these speech variables before and after speech therapy for cleft palate speech disorders. METHOD Thirty-four speech samples of 14 children with a CP ± L (14 samples collected immediately before 10 hr of speech intervention, 14 samples collected immediately after speech intervention, and six randomly selected samples that were duplicated to assess intrarater reliability) were perceptually assessed by 26 adult naïve listeners. The listening panel consisted of nine men and 17 women (age range: 18-51 years). The speech variables included speech understandability, speech acceptability, hypernasality, hyponasality, nasal airflow, and articulation, which were assessed on a visual analog scale. Furthermore, the need for speech therapy was assessed. RESULTS Good to very good interrater reliability was observed for the naïve listeners' ratings of all speech variables. A significant time effect was found for the pre- and postevolution of the speech variables "speech understandability," "speech acceptability," "nasal airflow," and "articulation." This time effect indicates an improvement of these variables postintervention. According to the naïve listeners, children were less in need of additional speech therapy after the 10-hr intervention period compared to assessments before this intervention period. CONCLUSIONS Adult naïve listeners perceptually identified an improvement in different speech variables after 10 hr of cleft palate speech therapy. These findings confirm previous assessments of expert speech-language pathologists and suggest that speech improvements after cleft palate speech therapy can also be perceived by communication partners outside the therapy room. Perceptual ratings of naïve listeners can, thus, be used to add life-situation significance to the assessments of experts. Future research could include both expert raters and caregivers or relatives of children with a CP ± L in listening panels, as previous knowledge on craniofacial anomalies may lead to different results.

Abstract
Background The International Consortium of Health Outcome Measurements (ICHOM) standard set for cleft care appraisal recommends clinicians assess articulation with percentage consonants correct (PCC) and velopharyngeal function with velopharyngeal competency rating (VPC-R). This study explores the utility and limitations of these generic measures in detecting cleft speech sound disorders by comparing them with two cleft-specific speech-rating systems, cleft audit protocol of speech-augmented Americleft modification (CAPS-A-AM) and Pittsburgh weighted speech scale (PWSS). Methods Consecutive children with repaired, nonsyndromic cleft lip/palate, aged 5 years or older (n = 27) underwent prospective speech evaluations conducted at a single academic institution. These evaluations were conducted, recorded, and evaluated by blinded speech-language pathologists experienced with all tools. Results When comparing measures of articulation, PCC scores correlated better with scores for relevant subcomponents of CAPS-A-AM than PWSS. When comparing measures of velopharyngeal function, VPC-R scores correlated well with relevant components of both scales. Using a "screening test versus diagnostic test" analogy, VPC-R ratings were 87.5% sensitive and 73.7% specific for detecting velopharyngeal dysfunction according to subcomponents of CAPS-A-AM, and 70.6% sensitive and 100% specific according to subcomponents of PWSS. Conclusions This exploratory study demonstrates that PCC and VPC-R perform moderately well in detecting articulatory and velopharyngeal dysfunction in patients with cleft lip/palate; however, these tools cannot describe nuances of cleft speech sound disorder. Thus, although PCC and VPC-R adequately track basic minimum outcomes, we encourage teams to consider extending the standard set by adopting a cleft-specific measurement system for further evaluation of the tools.

Abstract
SUMMARY Velopharyngeal insufficiency (VPI) is a complication following primary palatoplasty that can lead to hypernasality of the voice and other speech problems. The conversion Furlow palatoplasty for VPI can be performed with the addition of buccal flaps to provide additional tissue for palatal repair. In this study, the authors aimed to determine the effectiveness of buccal flaps with conversion Furlow palatoplasty in secondary management of VPI. A retrospective review of patients undergoing surgical repair of VPI between 2016 and 2020 was performed. Patients underwent either conversion Furlow palatoplasty alone (FA) or conversion Furlow palatoplasty with buccal flaps (FB) for VPI after primary straight-line repair of the palate. The authors reviewed medical records to collect demographics, operative information, and preoperative and postoperative speech scores. Of the 77 patients in the study, 16 (21%) had a revision that incorporated buccal flaps. The median age at cleft palate revision surgery was 8.97 years in the FA group and 7.96 years in the FB group ( P = 0.337). In the FA group, four patients (7%) developed a postoperative fistula, compared with zero patients in the FB group. The average time to follow-up after revision surgery was 3.4 years (range, 7 months to 5.9 years). Both cohorts demonstrated a decrease in hypernasality and total parameter scores postoperatively. The use of buccal flaps in revision Furlow palatoplasty could decrease the risk for postoperative complications. The use of data from a larger patient population from multiple institutions is warranted to determine true significance. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
AIM Videofluroscopy studies of speech are a recognized assessment of velopharyngeal insufficiency (VPI). Yet, this method is subjective and has low inter-rater reliability. Quantitative measures of timing, distance, and area in videofluoroscopic studies of swallowing have been shown to be valid and reliable, but quantitative measures are not routinely used in videofluroscopy studies for VPI. This study explored the use of quantitative measures in patients with VPI in terms of feasibility and reliability. METHODS Forty patients of mixed etiology diagnosed with VPI through perceptual speech assessment underwent videofluroscopy. Anatomical landmarks and timing, distance, and area measurements were taken of the velopharyngeal port at rest and during speech tasks using specialized Swallowtail software. 50% of measures were double-blind rated to test inter-rater reliability. Raters reported on the time they took to complete each assessment and the challenges they had. Associations between measures were explored. RESULTS Ten timing, line, and area measures were developed based on 3 landmarks. Measures had moderate-substantial inter-rater reliability (intraclass coefficient: 0.69-0.91) except for time to lift (secs), which only achieved fair agreement (intraclass coefficient: 0.56). Measures demonstrated internal consistency ( R >0.60). Raters took, on average, 15 mins per patient and reported some challenges with image resolution, especially in timing measures where structures were blurred by movement. CONCLUSION Quantitative measures are reliable and have the potential to add novel information regarding VPI to support multidisciplinary decision-making. Further research with larger patient cohorts is needed to clarify how quantitative measures can support tailored decisions about surgical and therapeutic interventions in order to maximize outcomes for individuals.

Hofman L, van Dongen JA, van Rees RCM, Jenniskens K, Haverkamp SJ, Beentjes YS, van der Molen ABM, Paes EC. Speech correcting surgery after primary palatoplasty: a systematic literature review and meta-analysis. Clin Oral Investig 2023; 28:58. [PMID: 38157017 DOI: 10.1007/s00784-023-05391-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Accepted: 12/11/2023] [Indexed: 01/03/2024]
Abstract
OBJECTIVES In cleft palate patients, the soft palate is commonly closed using straight-line palatoplasty, Z-palatoplasty, or palatoplasty with buccal flaps. Currently, it is unknown which surgical technique is superior regarding speech outcomes. The aim of this review is to study the incidence of speech correcting surgery (SCS) per soft palatoplasty technique and to identify variables which are associated with this outcome. MATERIALS AND METHODS A systematic literature search was carried out according to the PRISMA guidelines. Inclusion and exclusion criteria were applied to focus on the incidence of SCS after soft palatoplasty. Additional variables like surgical modification, cleft morphology, syndrome, age at palatoplasty, fistula and assessment of velopharyngeal function were reported. A modified New-Ottawa Scale (NOS) was used for quality appraisal. Pooled estimates from the meta-analysis were calculated using a random-effects model. RESULTS One thousand twenty-nine studies were found of which 54 were included in the analysis. The pooled estimate proportion of SCS after straight-line palatoplasty was 19% (95% CI 15-24), after Z-palatoplasty 6% (95% CI 4-9), and after palatoplasty with buccal flaps 7% (95% CI 4-11). CONCLUSIONS A lower SCS rate was found in patients receiving Z-palatoplasty when compared to straight-line palatoplasty. We propose a minimum set of outcome parameters which ideally should be included in future studies regarding speech outcomes after cleft palate repair. CLINICAL RELEVANCE Current literature reports highly heterogenous data regarding cleft palate repair. Our recommended set of parameters may address this inconsistency and could make intercenter comparison possible and of better quality.

Abstract
OBJECTIVE Buccal myomucosal flaps (BMF) anatomically lengthen the palate in the treatment of velopharyngeal insufficiency (VPI). We systematically reviewed the existing literature on speech outcome of BMF palatal lengthening. DESIGN Three databases were used to identify studies of interest published in English. Studies that did not use standardized speech assessments were excluded. PRISMA checklist was followed, and the risk of bias in the included studies was assessed. SETTING Long-term follow up of patients. PATIENTS With history of cleft palate presenting with VPI. INTERVENTION BMF palatal lengthening. MAIN OUTCOME MEASURE Random-effects model meta-analyses were performed for hypernasality, intelligibility, and nasal air emission score improvements, which were derived from reported preoperative and postoperative scores, and controlled for variability of scales and timing of postoperative assessment. RESULTS From the initial 7115 articles, 13 were included in this review. Two of these had a significant patient overlap and a study with a smaller patient population was excluded. All 12 included articles met the National Institutes of Health Quality Assessment Tool criteria. Six retrospective studies evaluated 230 patients and six prospective studies evaluated 181 patients. The most common indications for BMF were large size of the velopharyngeal gap and prior surgery for VPI. Meta-analyses demonstrated effect sizes below zero, confirming the improvement of standardized assessment scores in patients with VPI after BMF palatal lengthening. Egger regressions revealed low risk of publication bias. CONCLUSIONS BMF palatal lengthening provides adequate treatment for VPI in patients with large velopharyngeal gap size and a history of prior unsuccessful surgery.

Abstract
Velopharyngeal insufficiency (VPI) after palatoplasty is caused by improper anatomy preventing velopharyngeal closure and manifests as a hypernasal resonance, audible nasal emissions, weak pressure consonants, compensatory articulation, reduced speech loudness, and nostril or facial grimacing. A multidisciplinary team using multimodal instruments (speech analysis, nasoendoscopy, videofluoroscopy, nasometry, and magnetic resonance imaging) to evaluate velopharyngeal function should manage these patients. Careful monitoring of velopharyngeal function by a speech pathologist remains paramount for early identification of VPI and the perceptual assessment should follow a standardized protocol. The greatest methodology problem in CLP studies has been the use of highly variable speech samples making comparison of published results impossible. It is hoped that ongoing international collaborative efforts to standardize procedures for collection and analysis of perceptual data will help this issue. Speech therapy is the mainstay treatment for velopharyngeal mislearning and compensatory articulation, but it cannot improve hypernasality, nasal emissions, or weak pressure consonants, and surgery is the definitive treatment for VPI. Although many surgical methods are available, there is no conclusive data to guide procedure choice. The goal of this review article is to present a review of established diagnostic and management techniques of VPI.

Abstract
PURPOSE Individuals born with a cleft palate with or without a cleft lip (CP ± L) often experience functional, aesthetic, and psychosocial consequences well into adulthood. This study aimed to investigate outcomes of speech and health-related quality of life (HRQoL) in adults with a CP ± L who received interdisciplinary cleft care at the Ghent University Hospital using valid, reliable, and condition-specific instruments. METHOD Thirteen Belgian Dutch-speaking participants with a CP ± L with a mean age of 25.4 years (SD = 5.1, range: 20-33 years) and an age- and gender-matched control group of 13 participants without a CP ± L with a mean age of 25.2 years (SD = 4.8, range: 20-32 years) were included in this study. Speech characteristics were evaluated perceptually and instrumentally. HRQoL was assessed through standardized patient-reported outcome measures. Outcomes were compared with those of the control group and to normative data where available. RESULTS Participants with a CP ± L in this sample demonstrated significantly lower speech acceptability (p < .001) and higher rates of hypernasality (p = .015) and nasal turbulence (p = .005) than the control group. They showed significantly higher satisfaction with appearance of the cleft scar compared with norms of adults with a CP ± L (p = .047). No other differences in speech characteristics, sociodemographics, or HRQoL were found between participants with and without a CP ± L. CONCLUSIONS The reduced speech acceptability and the presence of resonance and nasal airflow disorders may indicate the need for standardized long-term outcome measurement and interdisciplinary follow-up for speech characteristics and velopharyngeal insufficiency in young and middle adulthood in future clinical practice. Additional research is necessary to further substantiate these findings and to determine predictors for these continuing complications in adults with a CP ± L.

Abstract
BACKGROUND Submucous cleft palate (SMCP) is a particular subtype of cleft deformity for which the optimal surgical timing and technique are still under debate. This study aimed to identify potential prognostic factors for the speech outcome of patients with SMCP and provide evidence for further management strategy optimization. METHODS The authors reviewed patients with nonsyndromic SMCP who received either Furlow palatoplasty (FP) or posterior pharyngeal flap (PPF) between 2008 and 2021 in a tertiary hospital-based cleft center. Both univariate and multivariate logistic regression models were used to screen preoperative variables, including cleft type (overt or occult), age at surgery, mobility of velum and pharyngeal wall, velopharyngeal closure ratio, and pattern. The receiver operating characteristic curve was used to determine the cutoff value of the significant predictors for subgroup comparison. RESULTS A total of 131 patients were enrolled, with 92 receiving FP and 39 receiving PPF. Age at operation and cleft type were identified as having significant effects on FP outcome. Patients operated on before 9.5 years of age had a significantly higher velopharyngeal competence (VPC) rate than those operated on after that age. The speech outcome among patients with occult SMCP was significantly worse than that of patients with overt SMCP after FP treatment. No preoperative variable was found to be correlated with PPF outcome. PPF yielded a higher VPC rate than did FP among patients operated on after 9.5 years of age. CONCLUSIONS The prognosis of patients with SMCP treated with FP is sensitive to age at surgery and cleft type. PPF may be considered for older patients in settings with limited access to multiple surgical procedures, especially when occult SMCP is diagnosed. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
OBJECTIVE To design a technique of palate repair with predictable Velo Pharyngeal (VP) closure and normal speech - 'Suspension Palatoplasty' in speaking unrepaired Cleft Palate (CP) patients. To evaluate the results of patients with CP operated using the technique of 'Suspension palatoplasty' from 2014 -2018 in terms of surgical complications and speech outcomes. DESIGN An ambi-spective longitudinal clinical study. SETTING Comprehensive cleft care clinic in a private trust hospital. PATIENTS/ PARTICIPANTS Patients above 6 years of age with isolated CP, cleft lip and palate (CLP), operated using 'Suspension Palatoplasty' technique between 2014 and 2018 were included with minimum follow up period of 5 years. Subjective speech evaluation was done by two speech therapists and analysed. INTERVENTION Author designed the technique of 'Suspension Palatoplasty' which aims to suspend the soft palate repaired by 'Hybrid Palatoplasty' technique, close to the nasopharynx using narrow pharyngeal flap with the pedicle based superiorly at adenoids, for an acceptable VP closure. MAIN OUTCOME MEASURES Speech outcome and surgical complications were assessed. RESULTS Out of 94 cases operated with age ranging from 6 to 45 years, 59 (62.8%) had normal speech, 12 (12.8%) had articulation errors but with no Velo-Pharyngeal Insufficiency (VPI) and 23 patients (24.4%) had hypernasality/ nasal emission (Suspected VPI). None of them had difficulty in breathing but one patient had snoring. CONCLUSION 'Suspension Palatoplasty' is a simple primary operation with excellent speech outcomes with no obstructive sequelae in patients with speaking unrepaired cleft palate.

Abstract
The purpose of this study was to examine and compare surgical and speech outcomes of the posterior pharyngeal flap and sphincter pharyngoplasty following surgical management of velopharyngeal insufficiency in patients with 22q11.2 deletion syndrome (22q11.2DS). This systematic review followed the Preferred Reporting Items for Systematic Review and Meta-Analyses checklist and guidelines. Selected studies were chosen using a 3-step screening process. The 2 primary outcomes of interest were speech improvement and surgical complications. Preliminary findings based on included studies suggest a slightly higher rate of postoperative complications with the posterior pharyngeal flap in patients with 22q11.2DS but a lower percentage of patients needing additional surgery compared with the sphincter pharyngoplasty group. The most reported postoperative complication was obstructive sleep apnea. Results from this study provide some insight into speech and surgical outcomes following pharyngeal flap and sphincter pharyngoplasty in patients with 22q11.2DS. However, these results should be interpreted with caution due to inconsistencies in speech methodology and lack of detail regarding surgical technique in the current literature. There is a significant need for standardization of speech assessments and outcomes to help optimize surgical management of velopharyngeal insufficiency in individuals with 22q11.2DS.

Abstract
PURPOSE To analyze the effect of auditory-perceptual training by inexperienced speech-language pathologists in the classification of hypernasality in individuals with cleft lip and palate and compare their classification of hypernasality individually, with the gold standard evaluation, before and after this training. METHODS Three inexperienced speech-language pathologists used a four-point scale to assess 24 high-pressure speech samples from individuals with cleft lip and palate, before and after auditory-perceptual training. The speech samples corresponded to six samples of each degree of hypernasality. The speech-language pathologists received auditory-perceptual training during the assessments. They had access to anchor samples and immediate feedback of correct answers regarding the degree of hypernasality in training. RESULTS There was no significant difference in the overall percentage of correct answers when comparing before and after the auditory-perceptual training. There was a significant association and agreement of the three evaluators with a gold standard evaluation after training, with an increase in agreement for a single evaluator for absent and mild degrees of hypernasality. The dichotomous analysis of the data showed an increase in the Kappa Index of Agreement of this evaluator. Although there was an increase in the Index of Agreement between evaluators for absent, mild, and severe hypernasality, this increase did not reach statistical significance. CONCLUSION The auditory-perceptual training provided did not result in a significant improvement in the hypernasality classification for the inexperienced speech-language pathologists, even though the individual data analysis showed that the training favored one of the evaluators. Further studies involving gradual and more extensive auditory-perceptual training may favor the classification of hypernasality by inexperienced SLPs.

Abstract
OBJECTIVE To evaluate the postoperative outcomes together with analyzing the associated influencing factors following a late cleft palate repair by the Sommerlad-Furlow modified technique (S-F). MATERIALS AND METHODS In a retrospective cohort, 320 consecutive patients with cleft palate, who received S-F technique between 2011 and 2017, were reviewed. The patients were divided into three age groups, less than one year (143), one to two years (113), and greater than 2 years (64). The postoperative outcomes included wound healing (complete/fistula) and velopharyngeal function (VPF). RESULTS The overall cleft width was 10 ± 3.07 mm. The overall rates of complete wound healing and proper velopharyngeal function were 96.6% and 81.56%, respectively. No significant difference was found between the age groups regarding wound healing, with an overall fistula rate of 3.4%. The VPF was significantly varied among the age groups (P<0.001). In context, the rates of velopharyngeal insufficiency (VPI) were 9.8%, 14.2%, and 45.4% among patients repaired at ˂1, 1-2, and >2 years old, respectively. The cleft type was the most potential factor associated with fistula. The age at repair was identified as the most implicating factor for VPI. CONCLUSIONS The S-F technique had achieved low fistula rate and satisfactory speech outcome, especially in early repair group and even in the wide cleft palate. The older age at repair and severe cleft type had a major impact on the postoperative outcomes.

Abstract
OBJECTIVE To explore the speech outcomes of adult patients with repaired cleft palate through subjective perception evaluation and objective acoustic analysis, and to compare the differences in pronunciation characteristics between speakers with complete velopharyngeal closure (VPC) and velopharyngeal insufficiency (VPI) patients. PARTICIPANTS AND INTERVENTION Subjective evaluation indicators included speech intelligibility, nasality and consonant missing rate, for objective acoustic analysis, we used speech sample normalization and objective acoustic parameters included normalized vowel formants, voice onset time and the analysis of 3-dimensional spectrogram and spectrum, were carried out on speech samples produced by 3 groups of speakers: (a) speakers with velopharyngeal competence after palatorrhaphy (n=38); (b) speakers with velopharyngeal incompetence after palatorrhaphy (n=70), (c) adult patients with cleft palate (n=65) and (d) typical speakers (n=30). RESULTS There was a highly negative correlation between VPC grade and speech intelligibility (ρ=-0.933), and a highly positive correlation between VPC and nasality (ρ=0.813). In subjective evaluation, the speech level of VPI patients was significantly lower than that of VPC patients and normal adults. Although the nasality and consonant loss rate of VPC patients were significantly higher than that of normal adults, the speech intelligibility of VPC patients was not significantly different from that of normal adults. In acoustic analysis, patients with VPI still performed poorly compared with patients with VPC. CONCLUSIONS The speech function of adult cleft palate patients is affected by abnormal palatal structure and bad pronunciation habits. In subjective evaluation, there was no significant difference in speech level between VPC patients and normal adults, whereas there was significant difference between VPI patients and normal adults. The acoustic parameters were different between the 2 groups after cleft palate repair. The condition of palatopharyngeal closure after cleft palate can affect the patient's speech.

Abstract
OBJECTIVE Describe and compare the results of speech and velopharyngeal function in children with classic and occult submucous cleft palate undergoing interdisciplinary treatment at the Gantz Foundation. METHODS The clinical history of all patients born between 2012 and 2017 with a diagnosis of classic or occult submucous cleft palate was retrospectively reviewed. Preoperative and postoperative medical, surgical, and speech and language history were collected. RESULTS Twenty-eight cases diagnosed at the age of 44.8±23.9 months were included. Of these, 71.4% presented classic submucous cleft, and 28.6% occult. Before primary surgery, 7.1% had a diagnosis of the syndrome, and 21.4% were under study. A total of 39.3% had hearing difficulties and 21.4% used tympanic ventilation tubes. A total of 60.7% had language problems, 39.3% had compensatory articulation, 17.9% had absent hypernasality, and 21.4% had absent nasal emission. The team indicated primary palate surgery in 71.4%, of which 85% performed the surgery at the mean age of 61.7±24.7 months. The surgical technique was Furlow in 88.2% of the cases and intravelar veloplasty in the remaining 11.8%. Then, 3 cases underwent velopharyngeal insufficiency surgery; 2 of them eliminated hypernasality and reduced nasal emission. The age of diagnosis ( P =0.021) and the performance of velopharyngeal insufficiency surgery ( P =0029) of the occult submucous cleft palate group was significatively later than the classic cleft palate group. CONCLUSIONS Language, hearing, compensatory articulation, hypernasality, and nasal emission problems were recorded. A high percentage required primary surgery. Of these, a low proportion also required a velopharyngeal insufficiency surgery, which improved the velopharyngeal function of the children but did not completely adapt it. In this regard, early diagnosis is essential, as well as an analysis of each center primary closure protocol.

Abstract
Background This article describes the development of the Myanmar Articulation, Resonation, Nasal Emission, and Nasal Turbulence test for children with cleft lip and palate (CLP), and evaluation of its validity and reliability. Methods It was created by three Thai researchers and a Burmese research assistant based on Burmese phonology. The content validity was evaluated by six Burmese language experts. All test items were divided into three groups: high-pressure oral consonants, low-pressure oral consonants, and nasal consonants. Results All items (58-word and 32-phrase/sentence) gave an excellent level of the expert agreement (item-level content validity indexes = 1.00). The target items were illustrated as color pictures. Each picture was clearly drawn and easy to identify. As a pilot study of face validity, all pictures were administered to 10 typical-developing children. The actual testing was assessed by 10 CLP children, and the developed test was analyzed through consultation of the Burmese teachers and interpreters from a speech camp. Testing scores for a total including three groups of target items were shown acceptable for internal consistency reliability (ranged from 0.4 to 0.88). Conclusion The constructed test is valid in terms of its content.

Abstract
BACKGROUND Intelligibility measurement is influenced by the characteristics of a speaker, listener and contextual factors. This study addresses the clinical problem of measuring speech intelligibility in children with velopharyngeal insufficiency (VPI) in real-world conditions. AIMS The purpose of the study was to investigate the effects of background noise on speech intelligibility in speakers with velopharyngeal insufficiency (VPI) compared to typical speech. The study further determined the contribution of nasalance and articulation accuracy in judgments of intelligibility. METHODS & PROCEDURES Fifteen speakers diagnosed with VPI and their typical peers provided audio recordings of 20 sentences from the Hearing in Noise Test. Speech samples were presented over quiet and noise (+5 dB signal-to-noise ratio) conditions to 70 naïve listeners. Intelligibility scores from naïve listeners' orthographic transcriptions were obtained as the percentage of correctly identified words. OUTCOMES & RESULTS A repeated-measures analysis of variance showed diagnosis of VPI (F(1, 28) = 13.44, p = 0.001, and presence of noise (F(1, 28) = 39.18, p < 0.001) significantly affected the intelligibility scores. There was no interaction between the diagnosis of VPI and noise (F(1, 28) = 0.06, p = 0.80). The multivariate regression analysis indicated that nasalance and articulation accuracy explain a significant amount of variance in the intelligibility scores of VPI speakers in quiet (F(2, 12) = 7.11, p < 0.05, R2 = 0.55, R2 Adjusted = 0.47) and noise (F(2, 12) = 6.32, p < 0.05, R2 = 0.51, R2 Adjusted = 0.43), but the significance mainly came from the effect of percentage of consonants correct (β = 0.97, t(12) = 2.90, p = 0.01). Percentage of consonants correct significantly increased the speech intelligibility in either with or without noise conditions. CONCLUSIONS & IMPLICATIONS The current work suggests that background noise will significantly affect reductions in intelligibility in both groups; the effect is more prominent in VPI speech. It was also further noted that articulation accuracy significantly affected intelligibility in quiet and noise rather than nasalance scores. WHAT THIS PAPER ADDS What is already known on the subject Intelligibility measurement is influenced by the characteristics of a speaker, listener and contextual factors. Accordingly, it is essential to determine the degree to which speech assessments in the clinic can predict communication difficulties in the presence of background noise in real life. Background noise can adversely cause speech intelligibility degradation in individuals with speech disorders. What this study adds The study examined the effects of background noise on speech intelligibility in speakers with velopharyngeal insufficiency (VPI) secondary to cleft palate compared to typical speech. The study results suggested that the presence of background noise will significantly affect reductions in intelligibility in both groups; however, the effect is more prominent in VPI speech. What are the clinical implications of this work? We found out that the intelligibility of VPI speech is lower in the presence of background noise, and therefore, assessments of speech intelligibility in clinical settings should take this into account. To ensure effective communication in noisy environments, recommended strategies include selecting quiet locations, eliminating potential distractions and supplementing communication with nonverbal cues. It is important to recognize that the effectiveness of these strategies may vary depending on the individual and the specific communication context.

Abstract
Cleft palate is among the most common congenital disorders worldwide and is correctable through surgical intervention. Sub-optimal surgical results may cause velopharyngeal insufficiency (VPI). When symptomatic, VPI can cause hypernasal or unintelligible speech. The postoperative risk of VPI varies significantly in the literature but may be attributed to differences in study size, cleft type, surgical technique, and operative age. To identify the potential impact of these factors, a systematic review was conducted to examine the risk of VPI after primary palatoplasty, accounting for operative age and surgical technique. A search of PubMed, Embase, and Web of Science was completed for original studies that examined speech outcomes after primary palatoplasty. The search identified 4740 original articles and included 35 studies that reported mean age at palatoplasty and VPI-related outcomes. The studies included 10,795 patients with a weighted mean operative age of 15.7 months (range: 3.1-182.9 mo), and 20% (n=2186) had signs of postoperative VPI. Because of the heterogeneity in reporting of surgical technique across studies, small sample sizes, and a lack of statistical power, an analysis of the VPI risk per procedure type and timing was not possible. A lack of data and variable consensus limits our understanding of optimal timing and techniques to reduce VPI occurrence. This paper presents a call-to-action to generate: (1) high-quality research from thoughtfully designed studies; (2) greater global representation; and (3) global consensus informed by high-quality data, to make recommendations on optimal technique and timing for primary palatoplasty to reduce VPI.

Abstract
PURPOSE To investigate whether a novel electropalatography (EPG) therapy, underpinned by usage-based phonology theory, can improve the accuracy of target speech sounds for school-aged children and adults with persistent speech sound disorder (SSD) secondary to cleft palate +/- lip. METHOD Six consecutively treated participants (7-27 years) with long-standing speech disorders associated with cleft palate enrolled in a multiple baseline (ABA) within-participant case series. The usage-based EPG therapy technique involved high-volume production of words. Speech was assessed on three baselines prior to therapy, during weekly therapy, at completion of therapy, and 3 months post-therapy. Percent correct of target phonemes in untreated words and continuously connected speech were assessed through acoustic phonetic transcription. Intra- and inter-transcriber agreement was determined. RESULT Large to medium treatment effect sizes were shown for all participants following therapy (15-33 sessions). Percentage of targets correct for untreated words improved from near 0% pre-therapy, to near 100% for most target sounds post-therapy. Generalisation of target sounds to spontaneous connected speech occurred for all participants and ranged from 78.95-100% (M = 90.66; SD = 10.14) 3 months post-therapy. CONCLUSION Clinically significant speech change occurred for all participants following therapy. Response to the novel therapeutic technique is encouraging and further research is indicated.

Abstract
BACKGROUND Speech in individuals with cleft lip and/or palate (CLP) is a complex myriad of presenting symptoms. It is uniquely associated with the structural difference of velopharyngeal insufficiency (VPI), together with a wide and heterogeneous range of other aetiologies which often co-occur. The nature of the speech sound disorder (SSD) including VPI may also change over the course of an individual's care pathway. Differences in terminology and approaches to analysis are currently used, resulting in confusion internationally. Additionally, current diagnostic labels and classification systems in SSD do not capture the complexity and full nature of speech characteristics in CLP. AIMS This paper aims to explore the different aetiologies of cleft palate/VPI speech and to relate aetiology with speech characteristic(s). In so doing, it attempts to unravel the different terminology used in the field, describing commonalities and differences, and identifying overlaps with the speech summary patterns used in the United Kingdom and elsewhere. The paper also aims to explore the applicability of current diagnostic labels and classification systems in the non-cleft SSD literature and illustrate certain implications for speech intervention in CLP. METHODS AND PROCEDURES The different aetiologies were identified from the literature and mapped onto cleft palate/VPI speech characteristics. Different terminology and approaches to analysis are defined and overlaps described. The applicability of current classification systems in SSD is discussed including additional diagnostic labels proposed in the field. OUTCOMES AND RESULTS Aetiologies of cleft palate/VPI speech identified include developmental (cognitive-linguistic), middle ear disease and fluctuating hearing loss, altered oral structure, abnormal facial growth, VPI-structural (abnormal palate muscle) and VPI-iatrogenic (maxillary advancement surgery). There are four main terminologies used to describe cleft palate/VPI speech: active/passive and compensatory/obligatory, which overlap with the four categories used in the UK speech summary patterns: anterior oral cleft speech characteristics (CSCs), posterior oral CSCs, non-oral CSCs and passive CSCs, although not directly comparable. Current classification systems in non-cleft SSD do not sufficiently capture the full nature and complexity of cleft palate/VPI speech. CONCLUSIONS AND IMPLICATIONS Our attempt at identifying the heterogeneous range of aetiologies provides clinicians with a better understanding of cleft palate/VPI speech to inform the management pathway and the nature and type of speech intervention required. We hope that the unravelling of the different terminology in relation to the UK speech summary patterns, and those used elsewhere, reduces confusion and provides more clarity for clinicians in the field. Diagnostic labels and classification require international agreement. WHAT THIS PAPER ADDS What is already known on the subject Speech associated with cleft palate/velopharyngeal insufficiency (VPI) is a complex myriad of speech characteristics with a wide and heterogeneous range of aetiologies. Different terminology and speech summary patterns are used to describe the speech characteristics. The traditional classification of cleft palate/VPI speech is Articulation Disorder, although evidence is building for Phonological Disorder and contrastive approaches in cleft speech intervention. What this paper adds to existing knowledge This paper explores the range of aetiologies of cleft palate/VPI speech (e.g., altered oral structure, abnormal facial growth, abnormal palate muscle and iatrogenic aetiologies) and attempts to relate aetiology with speech characteristic(s). An attempt is made at unravelling the different terminology used in relation to a well-known and validated approach to analysis, used in the United Kingdom and elsewhere. Complexities of current diagnostic labels and classifications in Speech Sound Disorder to describe cleft palate/VPI speech are discussed. What are the potential or actual clinical implications of this work? There needs to be a common language for describing and summarising cleft palate/VPI speech. Speech summary patterns based on narrow phonetic transcription and correct identification of aetiology are essential for the accurate classification of the speech disorder and identification of speech intervention approaches. There is an urgent need for research to identify the most appropriate type of contrastive (phonological) approach in cleft lip and/or palate.

Abstract
OBJECTIVE Patients with a cleft palate often experience a velopharyngeal dysfunction known as velopharyngeal insufficiency (VPI). The purpose of this study was to examine the development of velopharyngeal function (VPF) following primary palatoplasty and the factors that are linked to it. METHODS A retrospective study was conducted to examine the medical records of patients who had cleft palate, with or without cleft lip (CP ± L) and underwent palatoplasty at a Tertiary Affiliated Hospital between 2004 and 2017. Postoperative evaluation of VPF was conducted at two follow-up times (T1, T2) and was classified as either normal VPF, mild VPI, or moderate/severe VPI. The consistency of VPF evaluations between the two time points was then assessed, and patients were categorized into either the consistent or inconsistent group. The study collected and analyzed data on gender, cleft type, age at operation, follow-up duration, and speech records. RESULTS The study included 188 patients with CP ± L. Out of these, 138 patients (73.4%) showed consistent VPF evaluations, while 50 patients (26.6%) showed inconsistent VPF evaluations. Among those with VPI at T1 (91 patients), 36 patients (39.6%) had normal VPF at T2. The rate of VPI decreased from 48.40% at T1 to 27.13% at T2, whereas the rate of normal VPF increased from 44.68% at T1 to 68.09% at T2. The consistent group had a significantly younger age at operation (2.90 ± 3.82 vs 3.68 ± 4.02), a longer duration of T1 (1.67 ± 0.97 vs 1.04 ± 0.59), and a lower comprehensive score of speech performance (1.86 ± 1.27 vs 2.60 ± 1.07) than the inconsistent group. CONCLUSIONS It has been verified that there are changes in the development of VPF over time. Patients who underwent palatoplasty at a younger age were more likely to have confirmed VPF diagnosis at the first evaluation. The duration of follow-up was identified as a critical factor that affects the confirmation of VPF diagnosis.

Abstract
BACKGROUND Submucous cleft palate (SMCP) is a subgroup of cleft palate that can present as velopharyngeal insufficiency due to muscle displacement. The pharyngeal flap and Furlow palatoplasty have been introduced to correct SMCP patient with velopharyngeal insufficiency. However, pharyngeal flap and Furlow palatoplasty can occur various complications. We consider the overlapping intravelar veloplasty (IVVP) can overcome these complications. Therefore, we present the speech outcomes of overlapping IVVP for the treatment of patients with SMCP. METHODS We retrospectively reviewed 12 patients with SMCP underwent overlapping IVVP between April 2016 and October 2018. The patients who underwent speech evaluation, nasometry, and nasoendoscopy before and after surgery and who were followed up for >18 months were enrolled in this study. RESULTS The average age of the patients was 5 years (range, 3-11 years) and the postoperative follow-up period ranged from 18 to 24 months (mean, 20 months). The preoperative perceptual speech evaluation was moderate and the postoperative evaluation was normal ( P < 0.01). The preoperative and postoperative nasalance scores obtained using a nasometer were 37.00 and 12.50, respectively, ( P < 0.01). Preoperative and postoperative velopharyngeal movements were grades 3 and 0, respectively, ( P < 0.01). CONCLUSIONS Our study showed that overlapping IVVP could provide successful correction of velopharyngeal insufficiency in patients with SMCP, including relatively old patients.

Abstract
Introduction Surgical techniques for soft palate repair aiming for zero velopharyngeal insufficiency (VPI) are still not achieved. Straight line closure of the soft palate by various techniques of intravelar veloplasty (IVVP) leads to higher incidence of VPI due to scar contracture. Furlow's Z plasty has long, narrow, thin mucosal flaps and mucomuscular flaps with malaligned muscle closure. We present a technique of "hybrid palatoplasty" which borrows from and adds to the existing methods, is robust, is easy to replicate, and results in normal speech consistently. Aim (1) To design a technique of "hybrid palatoplasty"-combining double opposing Z (DOZ) plasty and IVVP, which is applicable to all types of cleft palate. (2) To evaluate the results of cleft palate children operated using the technique of "hybrid palatoplasty" from 2014 to 2015 in terms of surgical complications (fistulae and dehiscence) and incidence of VPI. Methods Our procedure combines aspects of both DOZ and IVVP. It is simplified with design of smaller Z plasties. On one side, from the oral Z plasty muscle is dissected off and sutured to the nasal mucomuscular flap of the opposite side to complete the palatal sling. Oral Z plasty is purely mucosal and reverse of the nasal side. A total of 123 cases, operated below 5 years of age were followed up. Speech was assessed by direct evaluation and tele-evaluation. Results A total of 123 cases, below 5 years of age, were operated between 2014 and 2016 with at least 5 years of follow-up. Note that 120 had normal speech, and 3 had VPI of which 2 were subsequently corrected and went on to develop normal speech. Conclusion This novel "hybrid palatoplasty" is a simple technique with good speech outcome as it combines the principles of Z plasty and direct muscle repair with palatal sling formation.

Abstract
Abstract
Introduction Velopharyngeal insufficiency (VPI) is a controversial pathology with many surgical options.
Objective To compare pharyngoplasty and retropharyngeal fat grafting and to build a prognostic tool to achieve perfect speech.
Methods Retrospective observational cohort study of 114 patients operated for VPI from 1982 to 2019 in a single tertiary center. The instrumental assessment was made using an aerophonoscope and nasofibroscopy. The variables sex, age, genetic syndromes, and type of diagnosis were analyzed with logistic regression model adjusted with propensity score. To generalize results and to build a surgical predictive tool, a marginal analysis concludes the study.
Results Among the patients (median [range] age 7 [4–48]), 63 (55.26%) underwent pharyngoplasty and 51 (44.74%) graft. The graft group had no complication, but it had a failure rate of 7.84%. The pharyngoplasty group had no failure, but one patient had postoperative obstructive sleep apnea. The marginal analysis demonstrated that age lower than 7 years, cleft lip and palate, absence of syndrome, and intermittent VPI were important predictive factors of good result regardless of surgical technique.
Conclusions Without a statistical demonstration of the superiority of pharyngoplasty over graft, and in the uncertainty of literature background, our perfect-speech patient profile represents an important tool for a postoperative forecast of results in which, like in the Master Mind game, every feature has to be considered not individually but as a pattern of characteristics whose association contributes to the outcome.

Abstract
BACKGROUND Speech abnormalities due to velopharyngeal insufficiency (VPI) significantly affect communication skills, self-esteem, and scholastic performance. It leads to a poor social, emotional, educational, and behavioral development and a poor quality of life overall in cleft lip palate (CLP) patients. Its early diagnosis and severity assessment using video-nasoendoscopy and speech assessment can significantly contribute to management. The present study evaluated VPI in CLP patients using both tools. METHODS A total of 48 patients with repaired cleft palate were subjected to speech and video-nasoendoscopic assessment. Speech assessment measured severity of hypernasality, speech intelligibility, and voice quality. Video-nasoendoscopy evaluated velopharyngeal port closure to grade the severity of VPI. The speech assessment and video-nasoendoscopy findings were analyzed and correlated. RESULTS There was a moderately strong statistically significant negative correlation between the grade of VPI and hypernasality (r = -0.542, p = 0.000). There was a stronger statistically significant negative correlation of grade of velopharyngeal port insufficiency with speech intelligibility (r = -0.634, p = 0.000). About 72% of the patients had abnormal voice quality. CONCLUSION This study is the first attempt at diagnosing and grading VPI on a quantitative scoring based on a ratio scale for the motion of soft palate and pharyngeal walls. The strong correlation between endoscopic grading and speech analysis findings warrants further evaluation of nasoendoscopic grading of VPI in more studies.

Abstract
BACKGROUND AND AIMS Individuals with speech disorders are often judged more negatively than peers without speech disorders. A limited number of studies examined the attitudes of adolescents toward peers with speech disorders due to a cleft lip with or without a cleft of the palate (CL ± P). Therefore, the aim of the present study was to investigate the attitudes of peers toward the speech of adolescents with CL ± P. METHOD Seventy-eight typically developing adolescents (15-18 years, 26 boys, 52 girls) judged audio and audiovisual samples of two adolescents with CL ± P based on three attitude components, i.e., cognitive, affective, and behavioral. The degree of speech intelligibility was also scored by their peers. The study investigated whether the three attitudes were determined by speech intelligibility or appearance of an individual with CL ± P. Furthermore, the influence of knowing someone with a cleft, the age, and gender of the listeners on their attitudes were explored. RESULTS A significantly positive correlation was found between the speech intelligibility percentage and the three different attitude components: more positive attitudes were observed when the speech intelligibility of the speaker was higher. A different appearance due to a cleft lip does not lead to more negative attitudes. Furthermore, boys seem to have more negative attitudes toward individuals with CL ± P compared to girls. CONCLUSION This study provided additional evidence that peers show more negative attitudes toward adolescents with less intelligible speech due to CL ± P. Intervention should focus on changing the cognitive, affective, and behavioral attitudes of peers in a more positive direction and remove the stigma of patients with a cleft. Further research is needed to verify these results.

Abstract
The aim of this study was to analyze speech intelligibility of children, who had undergone microsurgical soft palate repair according to Sommerlad. Cleft palate patients were treated by closure of the soft palate according to Sommerlad at about 6 months of age. At the age of 11, their speech was evaluated through automatic speech recognition. Word recognition rate (WR) was used as the outcome parameter of automatic speech recognition. To validate automatic speech results, an institute for speech therapy evaluated the speech samples for perceptual intelligibility. The results of this study group were compared to an age-matched control group. A total of 61 children were evaluated in this study, 29 in the study group and 32 in the control group. Study group patients had a lower word recognition rate (mean 43.03, SD 12.31) compared to the control group (mean 49.98, SD 12.54, p = 0.033). The magnitude of the difference was considered small (95% CI of the difference 0.6-13.3). The study group patients received significantly lower scores in the perceptual evaluation (mean 1.82, SD 0.58) compared to the control group mean (mean 1.51, SD 0.48, p = 0.028). Again, the magnitude of the difference was small (95% CI of the difference 0.03-0.57). Within the limitations of the study it seems that microsurgical soft palate repair according to Sommerlad at the age of 6 months might be a relevant alternative to other well established surgical techniques.

Abstract
PURPOSE This is a pilot study to apply an articulatory kinematic speech intervention that uses the principles of motor learning (PML) to improve speech and resonance outcomes for children with cleft palate. It is hypothesized that (a) treatment that applies select PML during practice will improve production of treated phonemes, representing both active and inconsistent passive errors, at word level in children with cleft palate; (b) effects of practice on phonemes with active or inconsistent passive errors will generalize to untreated exemplars of treated phonemes; and (c) learning will be retained for at least 1-month posttreatment. METHOD A multiple-baseline design across participants combined with a crossover single-case experimental model was used. Participants attended two 8-week blocks of twice-weekly face-to-face speech therapy (40-50 min/treatment) to treat active and inconsistent passive cleft speech errors using articulatory kinematic speech intervention that applied PML. The participants were four children with cleft-type speech errors. The primary dependent variable measured was percentage of words correct across treatment items, generalization items, and control items. Perceptual accuracy of target words was scored. Effect sizes were calculated to quantify the magnitude of treatment effect. RESULTS For three children with active and inconsistent passive cleft speech errors and one child with active cleft speech errors and developmental phonological speech errors, this approach resulted in improvements to their treated items and generalization to their untreated items. Inconsistent passive cleft speech errors were particularly responsive to the treatment in the three children who presented with these errors. CONCLUSION This Phase I study has shown that articulatory kinematic speech intervention that applies the PML is effective in improving the speech outcomes for children with cleft palate and that there is validity in pursuing further research into this approach.

Abstract
Spectro-temporal dynamics of consonant-vowel (CV) transition regions are considered to provide robust cues related to articulation. In this work, we propose an objective measure of precise articulation, dubbed the objective articulation measure (OAM), by analyzing the CV transitions segmented around vowel onsets. The OAM is derived based on the posteriors of a convolutional neural network pre-trained to classify between different consonants using CV regions as input. We demonstrate that the OAM is correlated with perceptual measures in a variety of contexts including (a) adult dysarthric speech, (b) the speech of children with cleft lip/palate, and (c) a database of accented English speech from native Mandarin and Spanish speakers.

Abstract
Introduction Compensatory articulations are speech disorders due to the attempt of the individual with cleft palate/velopharyngeal dysfunction to generate intraoral pressure to produce high-pressure consonants. Speech therapy is the indicated intervention for their correction, and an intensive speech therapy meets the facilitating conditions for the correction of glottal stop articulation, which is the most common compensatory articulation. Objective To investigate the influence of an intensive speech therapy program (ISTP) to correct glottal stop articulation in the speech of individuals with cleft palate. Methods Speech recordings of 37 operated cleft palate participants of both genders (mean age = 19 years old) were rated by 3 experienced speech/language pathologists. Their task was to rate the presence and absence of glottal stops in the 6 Brazilian Portuguese occlusive consonants (p, b, t, d, k, g) distributed within several places in 6 sentences. Results Out of the 325 pretherapy target consonants rated with glottal stop, 197 (61%) remained with this error, and 128 (39%) no longer presented it. The comparison of the pre- and posttherapy results showed: a) a statical significance for the p1, p2, p3, p4, t1, k1, k2 and d6 consonants (McNemar test; p < 0.05); b) a statistical significance for the p consonant in relation to the k, b, d, g consonants and for the t consonant in relation to the b, d, and g consonants (chi-squared test; p < 0.05) in the comparison of the proportion improvement among the 6 occlusive consonants. Conclusion The ISTP influenced the correction of glottal stops in the speech of individuals with cleft palate.

Abstract
PURPOSE The aim of this study was to assess the frequency and types of compensatory articulations (CAs) in nonsyndromic patients with velopharyngeal dysfunction (VPD) and various palatal anomalies and to determine the relationship between the frequency of CAs, type of palatal anomaly, and phonological errors. METHOD A total of 783 nonsyndromic, Hebrew-speaking patients with VPD and various palatal anomalies (cleft lip and palate [CLP], cleft palate [CP], submucous CP [SMCP], occult submucous CP [OSMCP], or non-CP) were studied retrospectively. Perceptual VPD tests, including articulation and phonological assessment, were conducted. CAs were described as below the level of the defect in the vocal tract (abnormal backing of oral targets to post-uvular place) or in front of it within the oral cavity (palatalization) and at the velopharyngeal port. RESULTS Among 783 patients, 213 (27.2%) had CAs. Most CAs (18.4%) occurred below the level of the defect, followed by CAs at the velopharyngeal port (12.0%) or in front of it (4.9%). No differences were found in the frequency of CAs between patients with CP (47.8%) or CLP (52.6%) and between those with non-CP (13.6%) or OSMCP (14.7%). SMCP patients had lower frequency of CAs (29.8%) than CP (p = .003) and CLP (p = .002) patients but higher frequency than OSMCP (p = .002) and non-CP (p = .002) patients did. Among the 783 patients, 247 (31.5%) had phonological errors. A higher frequency of phonological errors was found in patients with CAs (55.4%) compared to those without (22.6%) and in all palatal anomaly groups except CLP (31.4% vs. 23.9%). CONCLUSIONS CAs in nonsyndromic patients with VPD remained relatively high in all age groups, up to adulthood. CAs are influenced by inadequate velar length following palatal repair, as well as by oral structural abnormalities, whereas poor muscle function due to OSMCP and/or abnormal size and/or shape of nasopharynx has less influence. Errors produced in front of the velopharyngeal port are influenced by the structural anomaly of CLP. This information may contribute to general phonetic and phonological theories and genetic investigations about CP anomalies.

Abstract
INTRODUCTION Listener training is necessary to achieve agreement between perceptual ratings. However, evidence is limited regarding the effect of a training in the perceptual evaluation of cleft palate speech on the reliability of students in speech pathology. The aim of this study was to evaluate the short-term and longer-term effect of a training using the Belgian Dutch outcome tool for cleft palate speech on reliability and the students' experiences. METHODS A 2-h training was provided during a specialist course for 31 first year master students in speech pathology. Information regarding listener characteristics, speech documentation and speech analysis (speech parameters and rating scales) was discussed. This last part focused on the Belgian Dutch outcome tool for speech in patients with cleft palate, including reference samples and consensus listening exercises. Pre training (T1) and post-training reliability (immediately following the training (T2) and one month later (T3)) were collected for the speech variables speech understandability, speech acceptability, hypernasality, hyponasality, nasal emission and nasal turbulence that were rated by means of ordinal scales. Inter-rater reliability was determined with interclass correlation coefficients whereas percentages of agreement were calculated for the intra-rater reliability. RESULTS Qualitative inter-rater ICC categories improved for hyponasality and speech acceptability at T2 and T3, whereas the inter-rater reliability of the other variables remained stable regarding their interpreted categories. All ICC values quantitatively improved at T2, except hypernasality and nasal emission. At T3, three of those variables showed a small drop one month later. Regarding intra-rater reliability, a significant decrease for hypernasality and nasal turbulence was found at T2, whereas a significant increase was observed for nasal turbulence and speech acceptability at T3. All variables, except hypernasality, had improved intra-rater reliability at T3 in comparison with T1. Students experienced fewer difficulties with most variables after training. Evaluation of nasal emission and nasal turbulence remained however difficult and required, in the students' opinion, more attention. DISCUSSION & CONCLUSION Overall a positive training effect was noted, especially regarding the inter-rater reliability and the students' confidence in perceptual ratings. However, it remains a challenge to achieve a positive training effect for all target variables that is maintained over-time.
