Speech and language characteristics in individuals with nonsyndromic submucous cleft palate-A systematic review

Outcomes After Pharyngeal Flap Surgery in Children: A Comparison of Lined Versus Unlined Flaps

OBJECTIVE

The addition of a uvular flap (PFU) was hypothesized to improve outcomes over standard pharyngeal flap (PF) for correction of velopharyngeal dysfunction. We report differences in outcomes of PF vs PFU at our institution.

DESIGN

Retrospective cohort study.

SETTING

Tertiary children's hospital.

PATIENTS

Children who underwent PF or PFU with the three highest-volume surgeons at our institution in 2004-2017.

OUTCOME MEASURES

We examined differences in complications between groups, frequency and type of revision surgery, and speech-related measures including nasometry, pressure-flow testing (PFT) and perceptual speech analysis (PSA).

RESULTS

160 patients were included, 41 PF and 119 PFU (including 18 with Hogan technique). Patients undergoing PFU were older (7.6 yr vs 6.0 yr; p  =  0.037) and more likely to have cleft palate (63/119 vs 14/41; p  =  0.047). There was no significant difference in complications. With PFU, a decrease in airspace contracting revision surgeries was noted, (4/119 vs 8/41; p  =  0.002) which drove a reduction in revision surgery of all types (7/119 vs 13/41; p  =  0.033). However, patients that did undergo revision surgery after PFU underwent more revision procedures (p  =  0.032). PSA scores were found to be lower (less hypernasal) after PFU (p  =  0.009) compared to PF. Objective speech measures had varying results, with nasometry demonstrating a significant difference between groups (p  =  0.001), while PFT (p  =  0.525) did not demonstrate a statistical difference.

CONCLUSION

The use of a uvular lining flap in pharyngeal flap surgery may be associated with improved long term surgical outcomes, including both improvements in subjective and objective testing and a lower rate of revision surgery, without increased complications.

Comparison of Speech Outcomes Between Speech Therapy Only and Double-Opposing Z-Plasty Combined With Speech Therapy in Patients With Submucous Cleft Palate

The purpose of this study was to compare speech outcomes in patients with submucous cleft palate (SMCP) between speech therapy alone and double-opposing Z-plasty (DOZ) combined with speech therapy. The subjects were 67 patients with SMCP (overt type, 45 males, 22 females), who were divided into the observation group (n=18), the speech therapy group (n=24; duration, 17.8 mo), and the DOZ and speech therapy (DOZ-speech therapy) group (n=25; median age at DOZ, 5.3 years, duration, 18.6 mo). The median age at initial and final speech assessments were 3 and 5 years. After age, sex, syndromic status, duration of speech therapy, surgery timing, and speech outcomes were investigated, statistical analysis was performed. After tailored interventions, both isolated and non-isolated SMCP patients experienced significant improvements in speech outcomes, including nasal emission, hypernasality, compensatory articulation, and unintelligible speech. Since comparable improvements were observed, there were no significant differences in the final assessments regardless of initial speech issues between the speech therapy group and the DOZ-speech therapy group (all P>0.05). In the DOZ-speech therapy group, the rate of achieving "socially acceptable" speech was 92.3% in isolated cases and 90% in non-isolated cases. Multivariate analysis revealed that DOZ showed a tendency to reduce hypernasality, compensatory articulation, and "unintelligible" speech; syndromic or developmental conditions influenced outcomes in nasal emission and hypernasality; and initial hypernasality and compensatory articulation were correlated with outcomes. Therefore, DOZ surgery could be recommended to resolve hypernasality and compensatory articulation in SMCP patients before speech issues worsen.

What Technique Results in the Lowest Rate of Velopharyngeal Insufficiency in Patients With Submucous Cleft Palate? A Systematic Review and Meta-Analysis

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.

Effectiveness of secondary furlow palatoplasty with buccal myomucosal flap in correction of velopharyngeal insufficiency in patients with cleft palate

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.

CLINICAL RELEVANCE

This technique might be the surgical technique of choice while treating patients who are suffering from VPI after cleft palate repair.

Embryonic inhibition of colony-stimulating factor 1 receptor induces enlarged cartilaginous zone of the midpalatal suture in postnatal mice

OBJECTIVES

The midpalatal suture acts as the growth centre of the maxilla. Colony-stimulating factor 1 receptor (CSF1R) is essential for osteoclastogenesis. Deletion of CSF1R, and its ligand, results in significant craniofacial phenotypes but has not been studied in detail in the midpalatal suture.

MATERIALS AND METHODS

Pregnant ICR mice were treated with the CSF1R inhibitor PLX5622 at embryo Day 14.5 (E14.5) to E17.5. Pups at E18.5, postnatal Day 3 (P3) and P7 were collected for skeletal and histological staining. Osteoclasts were labelled using TRAP staining. PHH3 and TUNEL were employed to detect cell proliferation and apoptosis. Sox9, Ihh, and Col10a1 and Runx2, Col1a1, and DMP1 were used to detect chondrogenic differentiation and osteogenic differentiation, respectively. CD31, MMP9 and CTSK were utilized to assess vascular invasion and osteoclast secretion enzymes, respectively.

RESULTS

Embryonic inhibition of CSF1R resulted in a depletion of TRAP-positive cells and an enlarged cartilage zone of the midpalatal suture of postnatal mice. Compared to those in the control group, Sox9, Ihh, Col10a1, Runx2 and Col1a1 were upregulated, whereas TUNEL and DMP1 were decreased in this zone. In the trabecular region, Col10a1 was upregulated, while TUNEL, Col1a1 and DMP1 were downregulated. Moreover, the expression of MMP9, CTSK and CD31 was decreased, and invasion into the cartilage zone was delayed.

CONCLUSIONS

Embryonic inhibition of CSF1R led to an abnormally enlarged cartilaginous zone in the midpalatal suture, potentially due to delayed endochondral ossification caused by the depletion of osteoclasts. Additionally, we established a novel model of midpalatal suture dysplasia, offering prospects for future research.

Idiopathic Fistula in an Unrepaired Submucous Cleft Palate

Palatal fistulae are a recognised complication in individuals who have undergone surgical repair of a cleft palate, however, congenital or idiopathic palatal fistulae are rare. This report discusses the presentation and treatment of a 16-year-old female with a submucous cleft palate, who presented with a recent onset change in speech and evidence of a new palatal fistula. There was no history of recent infection or known trauma, and the patient had not undergone any previous palatal surgery. This report discusses the clinical presentation, recommended management and relevant literature for this rare phenomenon.

Prognostic Factors for Speech Outcome among Patients with Submucous Cleft Palate Managed by Furlow Palatoplasty or Posterior Pharyngeal Flap

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.

Evidence Mapping and Quality Analysis of Systematic Reviews on Various Aspects Related to Cleft Lip and Palate

BACKGROUND

Management of cleft lip and palate is interdisciplinary. An evidence-mapping approach was envisaged to highlight the existing gaps in this field, using only the highest level of evidence.

OBJECTIVES

To conduct evidence mapping and quality analysis of systematic reviews and meta-analyses related to any aspect of cleft lip and palate.

SEARCH METHODS

The cleft lip and palate field was divided into 9 domains and 50 subdomains and a method of categorization of systematic reviews was established. A comprehensive search strategy was carried out in seven databases along with the search of gray literature and references of included articles.

SELECTION CRITERIA

Systematic reviews related to any aspect of cleft lip and palate, conducted by a minimum of two reviewers, with a comprehensive search strategy and adequate quality analysis were included.

DATA COLLECTION AND ANALYSIS

A self-designed, pre-piloted data-extraction sheet was used to collect information that was analyzed through an expert group discussion. Quality analysis was performed using ROBIS-I, AMSTAR 2, and the PRISMA checklist.

RESULTS

A total of 144 systematic reviews published between 2008 and 2022 were included. The largest number of these could be categorized in the therapeutic domain (n = 58). A total of 27% of the studies were categorized as inconclusive, 40% as partially conclusive, and 33% as conclusive. As per ROBIS-I, 77% of reviews had high risk of bias while 58% were graded as critically low in quality as per AMSTAR 2. The majority of systematic reviews showed low reporting errors.

CONCLUSIONS

The majority of systematic reviews related to cleft lip and palate relate to therapeutic and prognostic domains and show high risk of bias and critically low quality regardless of the source journal. The results of this paper might serve as a starting point encouraging authors to carry out high-quality research where evidence is lacking.

Osteoclast differentiation and dynamic mRNA expression during mice embryonic palatal bone development

This study is the first to investigate the process of osteoclast (OCL) differentiation, its potential functions, and the associated mRNA and signalling pathways in embryonic palatal bone. Our findings suggest that OCLs are involved in bone remodelling, bone marrow cavity formation, and blood vessel formation in embryonic palatal bone. We observed TRAP-positive OCLs at embryonic day 16.5 (E16.5), E17.5, and E18.5 at the palatal process of the palate (PPP) and posterior and anterior parts of the palatal process of the maxilla (PPMXP and PPMXA, respectively), with OCL differentiation starting 2 days prior to TRAP positivity. By comparing the key periods of OCL differentiation between PPMX and PPP (E14.5, E15.5, and E16.5) using RNA-seq data of the palates, we found that the PI3K-AKT and MAPK signalling pathways were sequentially enriched, which may play critical roles in OCL survival and differentiation. Csf1r, Tnfrsff11a, Ctsk, Fos, Tyrobp, Fcgr3, and Spi1 were significantly upregulated, while Pik3r3, Tgfbr1, and Mapk3k7 were significantly downregulated, in both PPMX and PPP. Interestingly, Tnfrsff11b was upregulated in PPMX but downregulated in PPP, which may regulate the timing of OCL appearance. These results contribute to the limited knowledge regarding mRNA-specific steps in OCL differentiation in the embryonic palatal bone.

A retrospective analysis of speech and hearing in patients receiving surgery for submucous cleft palate

Submucous cleft palate (SMCP) is an uncommon subtype of cleft palate that is associated with symptoms of velopharyngeal insufficiency (VPI), the most common being hypernasal speech. A high proportion of patients also suffer from conductive hearing loss, which is thought to be due to eustachian tube dysfunction. A number of surgical techniques have been proposed to correct the anatomical defect that is responsible for VPI. This exploratory study aims to describe surgical techniques and clinical outcomes in a series of patients who underwent surgical repair of SMCP at a single regional specialist cleft centre between 1999 and 2018. Through a retrospective case note review, records of 57 patients who underwent SMCP repair between the ages of 6 months and 16 years were examined. Patients underwent one of the three surgical techniques: Intravelar Veloplasty, Furlow or a novel technique we have termed as "Hemi-Furlow". Hypernasality, measured on the Great Ormond Street Speech Assessment, showed evidence of improvement post-operatively in all three surgical groups (P<0.005), with no evidence to favour any specific approach. Post-operative complications, including wound dehiscence and fistulae, occurred in nine patients (15.8%). Nine patients (15.8%) required revisional surgery, either due to post-operative complications or persistent speech problems. Otological disease was present in 54.4% of patients, comprising conductive hearing loss due to otitis media with effusion (52.6%) and sensorineural hearing loss (1.8%). There is now a need for large, multi-centre studies with robust outcomes measures to further examine relationships between surgical techniques and clinical outcomes in people born with SMCP.

Evaluating the Effect of Low Power Diode Laser 806 nm on the Healing of Unilateral Cleft Lip Scar: An Open-Label Comparative Study

OBJECTIVE

To investigate the effect of laser bio-modulation irradiation therapy on the scar after surgical correction of unilateral cleft lip.

DESIGN

a comparative, open-label study.

SETTING

we conducted the study in a university based tertiary hospital that recruited early wound healers of unilateral cleft lip correction.

PATIENTS

Eighty patients were divided into two groups: In study's group, patients undergo laser bio-modulation irradiation (n = 60); in the control group, patients were followed-up without intervention (n = 20).

INTERVENTION

In the study's group, patients underwent low-power diode Laser with wavelength of 806 nm and power of 100 mw.

MAIN OUTCOME

The change in the scar of cleft lip patients, which was assessed by clinical examination and ultrasound.

RESULTS

The median pigmentation score was significantly lower in the laser group (median = 1; IQR = 1-2) than the control group (median 2; IQR 1-3), with p-value of <0.001. Likewise, the median height score was significantly lower in the laser group (median = 1; IQR = 1-1) than the control group (median 1.5; IQR 1.5-2), with p-value of 0.001. The median pliability score was significantly lower in the laser group (median = 1; IQR = 1-1) than the control group (median 2.5; IQR 1-3), with p-value of <0.001. Finally, the median vascularity score was significantly lower in the laser group (median = 1; IQR = 1-1) than the control group (median 1.5; IQR 1-2), with p-value of <0.001.

CONCLUSION

laser bio-modulation irradiation therapy demonstrates a potential efficacy in managing the hypertrophic scars after surgical repair of unilateral cleft lip.

Velopharyngeal Insufficiency Treatment in Cleft Palate Patients: Umbrella Review

Velopharyngeal insufficiency may occur as a result of an anatomical or structural defect and may be present in patients with cleft lip and palate. The treatment options presented in the literature are varied, covering invasive and non-invasive methods. However, although these approaches have been employed and their outcomes reviewed, no conclusions have been made about which approach is the gold-standard. This umbrella review aimed to synthesize the current literature regarding velopharyngeal insufficiency treatments in cleft lip and palate patients, evaluating their effectiveness based on systematic reviews. A standardized search was carried out in several electronic databases, namely PubMed via Medline, Web of Science, Cochrane Library, and Embase. The quality of the included studies was evaluated using AMSTAR2 and degree of overlap was analyzed using Corrected Covered Area. Thirteen articles were included in the qualitative review, with only 1 in the non-invasive method category, and 12 in the invasive method category. All reviewed articles were judged to be of low quality. In symptomatic patients, treatment did not solely comprise speech therapy, as surgical intervention was often necessary. Although there was no surgical technique considered to be the gold standard for the correction of velopharyngeal insufficiency, the Furlow Z-plasty technique and minimal incision palatopharyngoplasty were the best among reported techniques.

Compensatory Articulation Errors in Patients With Velopharyngeal Dysfunction and Palatal Anomalies

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.

Quantifying changes in ultrasound tongue-shape pre- and post-intervention in speakers with submucous cleft palate: an illustrative case study

Ultrasound Tongue Imaging is increasingly used during assessment and treatment of speech sound disorders. Recent literature has shown that ultrasound is also useful for the quantitative analysis of a wide range of speech errors. So far, the compensatory articulations of speakers with cleft palate have only been analysed qualitatively. This study provides a pilot quantitative ultrasound analysis, drawing on longitudinal intervention data from a child with submucous cleft palate. Two key ultrasound metrics were used: 1. articulatory t-tests were used to compare tongue-shapes for perceptually collapsed phonemes on a radial measurement grid and 2. the Mean Radial Difference was reported to quantify the extent to which the two tongue shapes differ, overall. This articulatory analysis supplemented impressionistic phonetic transcriptions and identified covert contrasts. Articulatory errors identified in this study using ultrasound were in line with errors identified in the speech of children with cleft palate in previous literature. While compensatory error patterns commonly found in speakers with cleft palate have been argued to facilitate functional phonological development, the nature of our findings suggest that the compensatory articulations uncovered are articulatory in nature.

Osteogenic and angiogenic profiles of the palatal process of the maxilla and the palatal process of the palatine bone

Hard palate consists anteriorly of the palatal process of the maxilla (ppmx) and posteriorly of the palatal process of the palatine (ppp). Currently, palatal osteogenesis is receiving increasing attention. This is the first study to provide an overview of the osteogenesis process of the mouse hard palate. We found that the period in which avascular mesenchymal condensation becomes a vascularized bone structure corresponds to embryonic day (E) 14.5 to E16.5 in the hard palate. The ppmx and ppp differ remarkably in morphology and molecular respects during osteogenesis. Osteoclasts in the ppmx and ppp are heterogeneous. There was a multinucleated giant osteoclast on the bone surface at the lateral-nasal side of the ppmx, while osteoclasts in the ppp were more abundant and adjacent to blood vessels but were smaller and had fewer nuclei. In addition, bone remodeling in the hard palate was asymmetric and exclusively occurred on the nasal side of the hard palate at E18.5. During angiogenesis, CD31-positive endothelial cells were initially localized in the surrounding of palatal mesenchymal condensation and then invaded the condensation in a sprouting fashion. At the transcriptome level, we found 78 differentially expressed genes related to osteogenesis and angiogenesis between the ppmx and ppp. Fifty-five related genes were up/downregulated from E14.5 to E16.5. Here, we described the morphogenesis and the heterogeneity in the osteogenic and angiogenic genes profiles of the ppmx and ppp, which are significant for subsequent studies of normal and abnormal subjects.

Anxiety in Chinese Patients With Cleft Lip and/or Palate: A Preliminary Study

OBJECTIVES

To preliminarily analyze factors that affected the prevalence of anxiety in Chinese patients with cleft lip and/or palate (CL/P).

METHODS

The Generalized Anxiety Disorder Scale (GAD-7) was used to screen anxiety in Chinese CL/P patients. Non-CL/P individuals were also included as the control group. Sociodemographic and clinical data consisting of diagnosis, gender, only child or not, monthly household income, and current family location were collected to analyze possible factors that could affect the anxiety of this patient population.

RESULTS

One hundred forty-two and 78 valid questionnaires were collected from the study and control groups, respectively. The mean GAD-7 score of the study group (3.092 ± 3.381) was significantly lower than the control (3.987 ± 2.505). Moreover, the proportion of patients presenting with moderate-severe anxiety was larger in the study group than in the control group (6.6 vs. 0.0%). Statistically significant differences in GAD-7 scores were observed between the study and control groups when the patient was the only child, living in an urban area, or the monthly household income was between 1,000 and 5,000 yuan.

CONCLUSION

Although the severity of anxiety in Chinese CL/P patients was not severer than those without CL/P, there was a relatively high incidence of moderate-severe anxiety in CL/P patients, while the only child, current family location and the monthly household income played significant roles in affecting anxiety psychology.

Phonological Profile of Patients With Velopharyngeal Dysfunction and Palatal Anomalies

PURPOSE

This purpose of this study was to assess the frequency and types of phonological process errors in patients with velopharyngeal dysfunction (VPD) and the different types of palatal anomalies.

METHOD

A total of 808 nonsyndromic patients with VPD, who underwent follow-up at the Center for Cleft Palate and Craniofacial Anomalies, from 2000 to 2016 were included. Patients were stratified into four age groups and five subphenotypes of palatal anomalies: cleft lip and palate (CLP), cleft palate (CP), submucous cleft palate (SMCP), occult submucous cleft palate (OSMCP), and non-CP. Phonological processes were compared among groups.

RESULTS

The 808 patients ranged in age from 3 to 29 years, and 439 (54.3%) were male. Overall, 262/808 patients (32.4%) had phonological process errors; 80 (59.7%) ages 3-4 years, 98 (40, 0%) ages 4.1-6 years, 48 (24.7%) 6.1-9 years, and 36 (15.3%) 9.1-29 years. Devoicing was the most prevalent phonological process error, found in 97 patients (12%), followed by cluster reduction in 82 (10.1%), fronting in 66 (8.2%), stopping in 45 (5.6%), final consonant deletion in 43 (5.3%), backing in 30 (3.7%), and syllable deletion and onset deletion in 13 (1.6%) patients. No differences were found in devoicing errors between palatal anomalies, even with increasing age. Phonological processes were found in 61/138 (44.20%) with CP, 46/118 (38.1%) with SMCP, 61/188 (32.4%) with non-CP, 70/268 (26.1%) with OSMCP, and 25/96 (26.2%) with CLP. Phonological process errors were most frequent with CP and least with OSMCP (p = .001).

CONCLUSIONS

Phonological process errors in nonsyndromic VPD patients remained relatively high in all age groups up to adulthood, regardless of the type of palatal anomaly. Our findings regarding the phonological skills of patients with palatal anomalies can help clarify the etiology of speech and sound disorders in VPD patients, and contribute to general phonetic and phonological studies.

Intelligibility in 3-Year-Olds With Cleft Lip and/or Palate Using the Intelligibility in Context Scale: Findings from the Cleft Collective Cohort Study

Objective:

To provide comparison data on the Intelligibility in Context Scale (ICS) for a sample of 3-year-old English-speaking children born with any cleft type.

Design:

Questionnaire data from the Cleft Collective Cohort Study were used. Descriptive and inferential statistics were carried out to determine difference according to children’s cleft type and syndromic status.

Participants:

A total of 412 children born with cleft lip and/or palate whose mothers had completed the ICS when their child was 3 years old.

Main Outcome Measure(s):

Mothers’ rating of their children’s intelligibility using the ICS.

Results:

The average ICS score for the total sample was 3.75 ( sometimes-usually intelligible; standard deviation [SD] = 0.76, 95% CIs = 3.68-3.83) of a possible score of 5 ( always intelligible). Children’s speech was reported to be most intelligible to their mothers (mean = 4.33, SD = 0.61, 95% CIs = 4.27-4.39) and least intelligible to strangers (mean = 3.36, SD = 1.00, 95% CIs = 3.26-3.45). There was strong evidence ( P < .001) for a difference in intelligibility between children with cleft lip only (n = 104, mean = 4.13, SD = 0.62, 95% CIs = 4.01-4.25) and children with any form of cleft palate (n = 308, mean = 3.63, SD = 0.76, 95% CIs = 3.52-3.71). Children born with cleft palate with or without cleft lip and an identified syndrome were rated as less intelligible (n = 63, mean = 3.28, SD = 0.85, 95% CIs = 3.06-3.49) compared to children who did not have a syndrome (n = 245, mean = 3.72, SD = 0.71, 95% CIs = 3.63-3.81).

Conclusions:

These results provide preliminary comparative data for clinical services using the outcome measures recommended by the International Consortium for Health Outcomes Measurement.

Clinical interventions and speech outcomes for individuals with submucous cleft palate

Background

This study aimed to identify the initial diagnostic characteristics and treatment status of children with submucous cleft palate (SMCP) and to examine the relationship between the timing of surgical correction and the degree of articulation and resonance improvement.

Methods

This retrospective study included 72 children diagnosed with SMCP between 2008 and 2016. The evaluation criteria were the age of the initial visit, total number of visits, age at the end of treatment, speech problems, resonance problems, and speech therapy.

Results

Children with SMCP first visited the hospital at an average age of 34.32 months, and speech problems were identified at an average age of 48.53 months. Out of 72 children, 46 underwent surgery at an average age of 49.74 months. Four of these children required secondary surgery at an average age of 83.5 months. Among the children who underwent surgery before 3 years of age, 70% exhibited articulation improvements, with mild-to-moderate hypernasality. Articulation improvements showed no statistically significant differences according to age at the time of surgery. However, children who underwent surgery before 4 years had a better hypernasality rating than those who underwent surgery after 4 years of age.

Conclusions

Children with SMCP tend to undergo delayed treatment because the anatomical symptoms in some children with SMCP are unclear, and surgical interventions are considered only after speech problems are clarified. Starting interventions as early as possible reduces the likelihood of receiving secondary surgery and speech therapy, while increasing expectations for positive speech function at the end.

[Current status of initial diagnosis of speech sound disorder in a child healthcare clinic]

OBJECTIVE

To investigate the understanding of speech sound disorder (SSD) among child health practitioners.

METHODS

The clinical data of 506 children with an initial diagnosis of SSD from January 2017 to May 2019 were retrospectively analyzed.

RESULTS

Of the 506 SSD children, 90.5% had a description of developmental behavior in their medical records; 97.6% received a developmental-behavioral evaluation, mostly intellectual and developmental screening tests, which were given to 95.8% (485/506) of the total children. A total of 116 (22.9%) children also had neurodevelopmental disorders, commonly presenting with language disorder, global developmental delay, and intellectual disability; however, 53 (45.7%) of the 116 children had no history records of such abnormal developmental behavior. The incidence of neurodevelopmental disorders was significantly higher in the children with abnormal hearing reported by their families than in the children with normal hearing reported by their families (P<0.001). The children with abnormal response to sound stimulation on physical examination had significantly more frequent neurodevelopmental disorders than those with normal response to sound stimulation (P<0.05). Among the 506 children with SSD, hearing condition was ignored in 33.2% in history records, and in 31.2% on physical examination. Ninety-two children (18.2%) completed the diagnostic hearing test, 12% (11/92) of whom were diagnosed with hearing loss. Of the 11 children with hearing loss, three had passed a hearing screening, three had family-reported normal hearing, and seven had normal response to sound stimulation on physical examination.

CONCLUSIONS

SSD is frequently comorbid with neurodevelopmental disorders in children. Children's communication performance is a key to the diagnosis of neurodevelop-mental disorders. It's necessary to the diagnosis of SSD to perform a medical history collection about neuropsychological development and a developmental-behavior evaluation. There is a high proportion of children with SSD receiving the developmental-behavioral evaluation, suggesting that child health practitioners pay close attention to the neuropsychological development of SSD children, but mostly, the evaluation merely involves intellectual developmental screening tests. The detection rate of hearing loss in children with SSD is high. However, child health practitioners underestimate this problem, and have an insufficient understanding of the importance of the diagnostic hearing test. The diagnostic hearing test should be the preferred recommendation for assessing hearing ability rather than past hearing screening results or children's response to sound stimulation in life scenes.

The Correlation Between Consonant Articulation and Velopharyngeal Function in Patients With Unoperated Submucous Cleft Palate

Submucous cleft palate (SMCP) is a congenital condition related to abnormal muscle attachments within the soft palate. Even though hypernasality and nasal emission, the primary symptom of SMCP, have been well-documented, research on articulation errors is currently lacking. The object of this study was to examine the consonant articulation in patients with unoperated SMCP and its possible correlation with the velopharyngeal function. This study analyzed the perceptual speech assessment and nasopharyngoscopy data of 338 patients with unoperated SMCP between years 2008 and 2016 retrospectively. The mean age of the patients was 13.27 years. About 125 patients showed velopharyngeal competence (VPC), 174 velopharyngeal incompetence (VPI), and 39 marginal VPI (MVPI). Among the 338 patients, 137 presented normal articulation, 124 consonant omission, 25 compensatory articulation, 36 consonant weakening, 51 consonant substitution, and 36 posterior placement. About 70.40% VPC patients, 17.24% VPI patients, and 48.72% MVPI patients demonstrated normal articulation. About 59.20% VPI patients showed consonant omission. The results demonstrated that consonant articulation varied among patients with unoperated SMCP and was correlated with their velopharyngeal functions, while consonant omission was the most common articulation error. Velopharyngeal closure pattern was not associated with either velopharyngeal function or consonant articulation.

Exploring the speech and language of individuals with non-syndromic submucous cleft palate: a preliminary report

BACKGROUND

Submucous cleft palate (SMCP) has a heterogeneous presentation and is often identified late or misdiagnosed. Diagnosis is prompted by speech, resonance or feeding symptoms associated with velopharyngeal insufficiency. However, the broader impacts of SMCP on communication have rarely been examined and therefore are poorly understood.

AIM

To describe the communicative profile of individuals with non-syndromic SMCP by examining speech, language and pragmatics (social language).

METHODS & PROCEDURES

Fifteen participants with SMCP aged 5;1-12;8, without a genetic diagnosis, participated in the study. Participants completed standardized assessments examining language, resonance, speech and non-verbal intellect. Parents also completed the Children's Communication Checklist (CCC-2), which provided a measure of overall communicative ability, including pragmatic skills. Formal language outcomes were compared with two cohorts: 36 individuals with overt non-syndromic clefts and 129 individuals with no history of clefting.

OUTCOMES & RESULTS

Speech intelligibility was reduced secondary to hypernasality, disordered articulation and/or impaired phonology (n = 7) in children with SMCP. Poorer overall language outcomes were observed for children with SMCP compared with both those with overt clefts and no history of clefting (p < 0.001). Language scores for children with SMCP ranged from impaired (n = 6) to above the standardized mean (n = 4). Receptive and expressive language performance were independently correlated with non-verbal IQ (p < 0.01). Those with severe language impairment (n = 4) also had borderline or impaired non-verbal IQ. Parents reported that speech and semantics were the most affected sub-domains of communication, while scores were the highest for the initiation domain. Speech and language skills were correlated strongly with pragmatics (r = 0.877, p < 0.01).

CONCLUSIONS & IMPLICATIONS

Overall, performance was variable within the SMCP group across speech, language and pragmatic assessments. In addition to well-documented speech difficulties, children with SMCP may have language or pragmatic impairments, suggesting that further neurodevelopmental influences may be at play. As such, for individuals with SMCP, additional clinical screening of language and pragmatic abilities may be required to ensure accurate diagnosis and guide both cleft and non-cleft related therapy programmes.
