Strip pharyngoplasty as a secondary functional surgery for persistent velopharyngeal insufficiency in cleft palate

Despite a satisfactory primary repair, velopharyngeal insufficiency (VPI) may be a sequel of soft palate clefts, resulting in hypernasality and phonation disorders. In order to increase the function of the pharyngeal flap during a secondary pharyngoplasty, we have developed a strip pharyngoplasty technique involving the middle constrictor muscle of the pharynx. This article describes the successive steps of the intervention and discuss its indications, advantages and limitations. Strip pharyngoplasty as a secondary functional surgery for persistent VPI after primary cleft palate repair is an attractive surgical procedure, particularly adapted to cases with defective muscle contraction by providing a muscle contingent in addition to the mucosal flap.

Protocol for a Prospective Observational Study of Revision Palatoplasty Versus Pharyngoplasty for Treatment of Velopharyngeal Insufficiency Following Cleft Palate Repair

OBJECTIVE

To present the design and methodology for an actively enrolling comparative effectiveness study of revision palatoplasty versus pharyngoplasty for the treatment of velopharyngeal insufficiency (VPI).

DESIGN

Prospective observational multicenter study.

SETTING

Twelve hospitals across the United States and Canada.

PARTICIPANTS

Individuals who are 3-23 years of age with a history of repaired cleft palate and a diagnosis of VPI, with a total enrollment target of 528 participants.

INTERVENTIONS

Revision palatoplasty and pharyngoplasty (either pharyngeal flap or sphincter pharyngoplasty), as selected for each participant by their treatment team.

MAIN OUTCOME MEASURE(S)

The primary outcome is resolution of hypernasality, defined as the absence of consistent hypernasality as determined by blinded perceptual assessment of a standard speech sample recorded twelve months after surgery. The secondary outcome is incidence of new onset obstructive sleep apnea. Statistical analyses will use propensity score matching to control for demographics, medical history, preoperative severity of hypernasality, and preoperative imaging findings.

RESULTS

Study recruitment began February 2021. As of September 2022, 148 participants are enrolled, and 78 have undergone VPI surgery. Enrollment is projected to continue into 2025. Collection of postoperative evaluations should be completed by the end of 2026, with dissemination of results soon thereafter.

CONCLUSIONS

Patients with VPI following cleft palate repair are being actively enrolled at sites across the US and Canada into a prospective observational study evaluating surgical outcomes. This study will be the largest and most comprehensive study of VPI surgery outcomes to date.

Predictors of Adverse Outcomes Following Cleft Palate Repair: An Analysis of Over 2500 Patients Using International Smile Train Data

OBJECTIVE

The objective of this study was to use data from Smile Train's global partner hospital network to identify patient characteristics that increase odds of fistula and postoperative speech outcomes.

DESIGN

Multi-institution, retrospective review of Smile Train Express database.

SETTING

1110 Smile Train partner hospitals.

PATIENTS/PARTICIPANTS

2560 patients.

INTERVENTIONS

N/A.

MAIN OUTCOME MEASURE(S)

Fistula occurrence, nasal emission, audible nasal emission with amplification (through a straw or tube) only, nasal rustle/turbulence, consistent nasal emission, consistent nasal emission due to velopharyngeal dysfunction, rating of resonance, rating of intelligibility, recommendation for further velopharyngeal dysfunction assessment, and follow-up velopharyngeal dysfunction surgery.

RESULTS

The patients were 46.6% female and 27.5% underweight by WHO standards. Average age at palatoplasty was 24.7 ± 0.5 months and at speech assessment was 6.8 ± 0.1 years. Underweight patients had higher incidence of hypernasality and decreased speech intelligibility. Palatoplasty when under 6 months or over 18 months of age had higher rates of affected nasality, intelligibility, and fistula formation. The same findings were seen in Central/South American and African patients, in addition to increased velopharyngeal dysfunction and fistula surgery compared to Asian patients. Palatoplasty technique primarily involved one-stage midline repair.

CONCLUSIONS

Age and nutrition status were significant predictors of speech outcomes and fistula occurrence following palatoplasty. Outcomes were also significantly impacted by location, demonstrating the need to cultivate longitudinal initiatives to reduce regional disparities. These results underscore the importance of Smile Train's continual expansion of accessible surgical intervention, nutritional support, and speech-language care.

Velopharyngeal Characteristics in Aarskog-Scott Syndrome: A Case Report

Aarskog-Scott syndrome (AAS), also known as facio-digito-genital syndrome, is a rare heterogenous syndrome characterized by facial dysmorphism, brachydactyly, and genetic abnormalities. Although severe craniofacial abnormalities have been reported in AAS, little is known about speech and resonance issues in AAS. Specifically, published data to date have only indicated reports of hypernasality associated with a cleft palate in AAS. This case report provides clinical and anatomic information surrounding hypernasal speech in the absence of an overt cleft palate in a patient with AAS.

The Early Operative Burden for Children Born with Cleft lip and Palate

OBJECTIVES

to audit the surgical management of infants born with non-syndromic cleft lip and palate (CLP) at an Australian cleft unit in a large tertiary paediatric hospital.

DESIGN

Retrospective cohort study.

SETTING

A tertiary Cleft centre.

PATIENTS

193 infants born with non-syndromic CLP were referred to the centre and underwent primary repair of their CLP between 2009 and 2020.Main Outcome Measures: (1) The timing and surgical repairs performed; (2) the frequency of postoperative complications; (3) the frequency of secondary Cleft surgery; and (4) the total Cleft-related operations performed for infants born with CLP.

RESULTS

Four different surgical repair techniques were performed by six surgeons, and postoperative complications were uncommon (n = 14). Rates of oronasal fistula surgery (10.5% at five years of age; 14.3% at eight years of age) and velopharyngeal insufficiency surgery (8.7% at five years of age; 14.3% at eight years of age) were not significantly different across the surgical repair groups (p-value >0.05) and were comparable to international Cleft centres. Children underwent an average of four operative procedures in this audit period, including primary Cleft repair, ear, nose and throat surgery, and dental care. Surgery for managing Eustachian tube dysfunction was the most common surgical intervention following primary Cleft repair.

CONCLUSIONS

Children born with non-syndromic CLP have a high early operative burden, with outcomes similar across the spectrum of techniques and surgeons.

Screening for congenital hearing impairment with brainstem evoked response audiometry in isolated orofacial cleft

Brainstem evoked response audiometry (BERA) is the most established and recommended objective audiometric method for the clinical diagnosis of hearing impairment in high-risk infants. It is unclear whether infants with orofacial clefts meet the criteria for the high-risk group. This retrospective cohort study evaluated the need for diagnostic BERA in infants with cleft palate with or without cleft lip by assessing the predisposition to and diagnosis of congenital hearing impairment. Data from 122 patients treated at a single cleft centre were evaluated. BERA was conducted at the time of palate repair at 4-6 months of age. Clinical follow-up was analysed up to 4 years. The presence of a syndrome was examined as a risk factor for congenital hearing impairment. Among the 122 patients, four had congenital sensorineural or mixed hearing loss requiring hearing aids. All affected patients had syndromes in addition to the cleft. Most patients with elevated hearing thresholds had transient conductive hearing loss. Most suspected sensorineural hearing loss initially diagnosed was refuted. However, a higher incidence of sensorineural hearing loss was found in patients with syndromic clefts, supporting the diagnostic use of BERA with initial surgery only in patients with syndromic clefts.

Language abilities and associated risk factors of school-aged children with cleft lip and palate

Previous research on children with cleft lip and palate (CLP) reported unequivocal findings with regard to language skills, with the majority suggesting persistent difficulties in early childhood. While expressive language deficits improved with age, receptive language skills were consistently lower than peers. Further study investigating the long term and persistent impact of language deficits amongst school-aged children with CLP is warranted. This was a cross-sectional study, aimed to determine the language abilities and explore the associated risk factors in Malay speaking children with CLP in Malaysia. Fifty-two children with CLP aged 7- to 12-year-old participated in this study. Language skills were assessed using the Malay Preschool Language Assessment Tool and the adapted Subway-School-age Language & Assessment Measures. Findings revealed that 14 (26.92%) school-aged children with CLP demonstrated language deficits. Children with CLP performed significantly poorer in reading comprehension (p = 0.031) and narrative (p = 0.026) skills. It was found that the age significantly influenced total receptive language score (β = 0.421, p = 0.003) and total expressive language score (β = 0.477, p = 0.000). Findings suggested that children with CLP may continue to have persistent language deficits into their school-age years. Recommendations for regular monitoring of language performance especially for those from younger age groups is warranted to help maximize school attainment.

Evaluation of maxillary arch symmetry in cleft patients undergoing orthodontic treatment: a comparative study

OBJECTIVE

Patients with a cleft require structured procedures to achieve feasible treatment results. Since many treatment protocols coexist without being superior to one another, this study investigated the Saarland University Hospital treatment concept for patients with unilateral and bilateral clefts to evaluate its effects upon dental arch dimensions until the early mixed dentition.

MATERIAL AND METHODS

Digitized plaster models were used for data collection. Records of 83 patients (Cleft n = 41 [UCLP n = 28, BCLP n = 13], Non-Cleft Control n = 42) comprised 249 casts. The evaluation included established procedures for measurements of edentulous and dentate jaws. Statistics included Shapiro-Wilk, Friedmann, Wilcoxon and Mann-Whitney-U-Tests for the casts. The level of significance was set at p < 0.05.

RESULTS

The cast analysis showed an approximation of arch dimensions towards those of age-matched patients without a cleft until early mixed dentition. The mean values of patients with and without cleft lip and palate were almost indistinguishable when compared in primary and/or early mixed dentition.

CONCLUSIONS

The evaluated treatment concept leads to feasible outcomes regarding dental arches in patients with unilateral and bilateral clefts compared to an age-matched non-cleft control.

CLINICAL RELEVANCE

The evaluated treatment concept leads to favorable outcomes until early mixed dentition.

Investigation of the effectiveness of articulation therapy through tele-practice on children with cleft palate in Khuzestan Province during COVID-19 pandemic

INTRODUCTION

A cleft palate is a common type of facial malformation. Compensatory articulation errors are one of the important causes of unclear speech in children with cleft palate. Tele-practice (TP) helps to connect therapists and clients for assessment and therapy. Our goal is to investigate the effectiveness of articulation therapy through tele-practice on cleft palate children in Khuzestan Province during the COVID-19 pandemic.

MATERIALS & METHODS

Before starting the treatment, a 20-min speech sample was recorded individually from all the children. Speech intelligibility and the percentage of correct consonants were assessed for each speech sample. The control group received treatment sessions in person at the cleft palate center, and the other group received treatment via tele-practice using the ZOOM platform. Treatment sessions were provided in the form of 45-60-min group sessions, twice a week, for 5 weeks (10 sessions in total). After 10 treatment sessions, the speech sample was recorded again. The level of parental satisfaction was measured using a Likert 5-level survey.

RESULTS

The mean score of intelligibility of the two groups decreased (-1.4400 and 0.7200). The two groups' mean percentage of correct consonants increased. (26.09 and 17.90). In both groups, the mean score of parents' satisfaction with the treatment was high (3.44 and 3.84). The mean of difference before and after the speech intelligibility and the percentage of correct consonants variables in both groups was statistically significant (P = 0.001 and P = 0.002, respectively). In both groups, the satisfaction variable was not associated with a statistically significant difference (P = 0.067).

CONCLUSION

The effectiveness of in-person therapy over a certain period of time is higher than tele-practice. Nevertheless, the results demonstrated an increase in the intelligibility of speech and the percentage of correct consonants in both groups, thus proving the effectiveness of articulation therapy in correcting compensatory articulation errors in children with cleft palate through in-person and tele-practice.

Multi-institutional Assessment of Otitis Media Epidemiology Using Real-world Data

OBJECTIVES

To determine rates and risk factors of pediatric otitis media (OM) using real-world electronic health record (PEDSnet) data from January 2009 through May 2021.

STUDY DESIGN

Retrospective cohort study.

SETTING

Seven pediatric academic health systems that participate in PEDSnet.

METHODS

Children <6 months-old at time of first outpatient, Emergency Department, or inpatient visit were included and followed longitudinally. A time-to-event analysis was performed using a Cox proportional hazards model to estimate hazard ratios for OM incidence based on sociodemographic factors and specific health conditions.

RESULTS

The PEDSnet cohort included 910,265 children, 54.3% male, mean age (months) 1.3 [standard deviation (SD) 1.6] and mean follow up (years) 4.3 (SD 3.2). By age 3 years, 39.6% of children had evidence of one OM episode. OM rates decreased following pneumococcal-13 vaccination (PCV-13) and the COVID-19 pandemic. Along with young age, non-Hispanic Black/African American or Hispanic race/ethnicity, public insurance, higher family income, and male sex had higher incidence rates. Health conditions that increased OM risk included cleft palate [adjusted hazard ratio (aHR) 4.0 [95% confidence interval (CI) 3.9-4.2], primary ciliary dyskinesia [aHR 2.5 (95% CI 1.8-3.5)], trisomy 21 [aHR 2.0 (95% CI 1.9-2.1)], atopic dermatitis [aHR 1.4 (95% CI 1.4-1.4)], and gastroesophageal reflux [aHR1.5 (95% CI 1.5-1.5)].

CONCLUSIONS

Approximately 20% of children by age 1 and 40% of children by age 3 years will have experienced an OM episode. OM rates decreased after PCV-13 and COVID-19. Children with abnormal ciliary function or craniofacial conditions, specifically cleft palate, carry the highest risk of OM.

Rare Association of Ankyloblepharon Filiforme Adnatum (AFA) with Cleft Palate - Case Report

The aim of this article is to discuss about rare representation of ankyloblepharon (an established chromosomal anomaly with aberration of p53 inherited as an autosomal dominant trait) with cleft of palate without any other feature of ectodermal dysplasia. The need to surgically address ankyloblepharon in order to avoid complications is also discussed.

Stem Cell-Based Regenerative Approaches for the Treatment of Cleft Lip and Palate: A Comprehensive Review

Cleft lip and/or palate (CLP) is a prevalent congenital craniofacial abnormality that can lead to difficulties in eating, speaking, hearing, and psychological distress. The traditional approach for treating CLP involves bone graft surgery, which has limitations, post-surgical complications, and donor site morbidity. However, regenerative medicine has emerged as a promising alternative, employing a combination of stem cells, growth factors, and scaffolds to promote tissue regeneration. This review aims to provide a comprehensive overview of stem cell-based regenerative approaches in the management of CLP. A thorough search was conducted in the Medline/PubMed and Scopus databases, including cohort studies, randomized controlled trials, case series, case controls, case reports, and animal studies. The identified studies were categorized into two main groups: clinical studies involving human subjects and in vivo studies using animal models. While there are only a limited number of studies investigating the combined use of stem cells and scaffolds for CLP treatment, they have shown promising results. Various types of stem cells have been utilized in conjunction with scaffolds. Importantly, regenerative methods have been successfully applied to patients across a broad range of age groups. The collective findings derived from the reviewed studies consistently support the notion that regenerative medicine holds potential advantages over conventional bone grafting and represents a promising therapeutic option for CLP. However, future well-designed clinical trials, encompassing diverse combinations of stem cells and scaffolds, are warranted to establish the clinical efficacy of these interventions with a larger number of patients.

Mandibular condyle volumes are associated with facial asymmetry in patients with cleft lip and palate: A retrospective cohort study

This study compares condylar volumetric asymmetry and facial asymmetry in patients with cleft lip and/or palate (CLP) and controls. The mandibular condyle is important to facial growth, but its role in facial asymmetry for those with CLP has not been described. Condylar volumes and mandibular asymmetry were retrospectively calculated using Mimics Version 23.0 (Materialise, Leuven, Belgium) from patients with CLP undergoing computed tomography (CT) imaging and a cohort of controls. A total of 101 participants, 60 with CLP and 41 controls, had mean condylar volumetric asymmetry of 16.4 ± 17.4 % (CLP) and 6.0 ± 4.0 % (controls) (p = 0.0002). Patients with CLP who had clinically significant chin deviation (>4 mm) had more asymmetric condyles than those without significant chin deviation (p = 0.003). The chin deviated toward the smaller condyle in patients with facial asymmetry more often than in patients without facial asymmetry (81 % vs. 62 %, p = 0.033). While controls had some degree of condylar asymmetry, it tended to be milder and not associated with facial asymmetry. There is a greater degree of condylar volumetric asymmetry in patients with CLP compared to individuals in the general population. Clinically significant facial asymmetry in CLP is associated with a higher degree of condylar asymmetry, with the facial midline deviating toward the smaller condyle.

Damaging Mutations in Contribute to Risk of Nonsyndromic Cleft Lip With or Without Cleft Palate

Novel or rare damaging mutations have been implicated in the developmental pathogenesis of nonsyndromic cleft lip with or without cleft palate (nsCL ± P). Thus, we investigated the human genome for high-impact mutations that could explain the risk of nsCL ± P in our cohorts.

We conducted next-generation sequencing (NGS) analysis of 130 nsCL ± P case-parent African trios to identify pathogenic variants that contribute to the risk of clefting. We replicated this analysis using whole-exome sequence data from a Brazilian nsCL ± P cohort. Computational analyses were then used to predict the mechanism by which these variants could result in increased risks for nsCL ± P.

We discovered damaging mutations within the AFDN gene, a cell adhesion molecule (CAMs) that was previously shown to contribute to cleft palate in mice. These mutations include p.Met1164Ile, p.Thr453Asn, p.Pro1638Ala, p.Arg669Gln, p.Ala1717Val, and p.Arg1596His. We also discovered a novel splicing p.Leu1588Leu mutation in this protein. Computational analysis suggests that these amino acid changes affect the interactions with other cleft-associated genes including nectins (PVRL1, PVRL2, PVRL3, and PVRL4) CDH1, CTNNA1, and CTNND1.

This is the first report on the contribution of AFDN to the risk for nsCL ± P in humans. AFDN encodes AFADIN, an important CAM that forms calcium-independent complexes with nectins 1 and 4 (encoded by the genes PVRL1 and PVRL4). This discovery shows the power of NGS analysis of multiethnic cleft samples in combination with a computational approach in the understanding of the pathogenesis of nsCL ± P.

Speech Outcomes After Palatal Lengthening Via Double Opposing Buccinator Myomucosal Flaps

BACKGROUND

Palatal lengthening is becoming a first-line treatment choice for cleft patients with velopharyngeal insufficiency (VPI). As cleft palate-related surgical outcomes are age dependent, speech outcomes may be similarly affected by patient age at the time of treatment. The primary goal of this study is to determine whether there are age-related speech outcome differences when double opposing buccinator myomucosal flaps are used as part of a palatal lengthening protocol and whether these outcome differences preclude utilization of this technique for specific patient age groups.

METHODS

A retrospective study was performed on consecutive nonsyndromic patients with VPI who underwent treatment using double opposing buccinator myomucosal flaps at our hospital between 2014 and 2021. Patients who completed the 15-month follow-up were stratified by age. Group A aged between 2 and 7 years (n = 14), group B aged 8 and 18 years (n = 23), and group C aged older than 18 years (n = 25) were included. Standardized perceptual speech evaluations and nasopharyngoscopy were performed. Hypernasality, soft palate mobility, and lateral palatal wall mobility were assessed both preoperatively and at a 15-month postoperative interval. Complications were also recorded. The χ2 test was used for statistical comparison.

RESULTS

All of the age-stratified patient groups in this study showed significant improvement in hypernasality, soft palate mobility, and lateral wall mobility (P < 0.01), with no statistically significant differences between the different patient age groups. Overall speech success was achieved in 69.4% of patients. Patients in group A achieved 78.6% speech success, patients in group B achieved 78.3% speech success, and patients in group C achieved 56% speech success, with no statistically significant differences being shown regarding speech success between the different patient age groups (P > 0.05).

CONCLUSIONS

Regardless of age, palatal lengthening via double opposing buccinator myomucosal flaps similarly improves speech outcomes.

Outcomes of primary repair of cleft palate using sommerled intravelar veloplasty associated with velocardiofacial syndrome

OBJECTIVES

Velocardiofacial syndrome, a prevalent microdeletion syndrome occurring in 1 in 2000-4000 live births, is marked by speech and language disorders, notably velopharyngeal dysfunction. This study investigates speech outcomes, nasometric and videofluoroscopic results before and after primary repair of cleft palate using the Sommerlad intravelar veloplasty (SIVV) technique within the Isfahan cleft care team for patients with velocardiofacial syndrome.

METHODS

Employing a quasi-experimental design, 19 participants with velocardiofacial syndrome, who underwent primary cleft palate repair by the Isfahan cleft care team, were included through convenience sampling. Perceptual and instrumental outcomes were assessed pre-and post-operatively. Statistical analysis encompassed paired t-tests and the non-parametric Wilcoxon signed-rank test (p < 0.05).

RESULTS

The study identified no statistically significant differences between pre-and post-surgical speech outcome parameters and nasalance scores. Nonetheless, a significant distinction emerged in the velopharyngeal closure ratio based on fluoroscopic evaluation (p = 0.038).

CONCLUSION

The efficacy of the SIVV technique in treating velopharyngeal dysfunction in velocardiofacial syndrome patients is inconclusive, demanding further research. Post-surgical speech outcomes are influenced by surgical technique, hypotonia, apraxia of speech, and surgery timing. Notably, an elevated velopharyngeal valve closure ratio, though anatomically indicative, does not exclusively predict surgical success.

Rehabilitation Using Hybrid Technique for Feeding Plate Fabrication in a 3-Month-Old Infant with Cleft Palate Defect Utilising Digital and Conventional Method: A Case Report

ABSTRACT

Cleft palate leads to difficulty in suckling, speech abnormalities, dental problems, hearing loss and middle ear infections. Feeding plate acts as a barrier between the oral and nasal cavities allowing the normal development of jaws and enhanced nutritional supply to the patient. Fabrication of the feeding plate using digital means provide better adaptability due to the engagement of all the possible favourable anatomic undercuts, thereby, providing better retention. This case report discusses the hybrid technique including both the digital and conventional means for fabrication of a feeding plate to obturate the defect between the oral and nasal cavity.

Three-dimensional finite element analysis on stress distribution after different palatoplasty and levator veli palatini muscle reconstruction

OBJECTIVES

To establish a three-dimensional finite element model of the upper palate, pharyngeal cavity, and levator veli palatini muscle in patients with unilateral complete cleft palate, simulate two surgical procedures that the two-flap method and Furlow reverse double Z method, observe the stress distribution of the upper palate soft tissue and changes in pharyngeal cavity area after different surgical methods, and verify the accuracy of the model by reconstructing and measuring the levator veli palatini muscle.

MATERIALS AND METHODS

Mimics, Geomagic, Ansys, and Hypermesh were applied to establish three-dimensional finite element models of the pharyngeal cavity, upper palate, and levator veli palatini muscle in patients with unilateral complete cleft palate. The parameters including length, angle, and cross-sectional area of the levator veli palatini muscle etc. were measured in Mimics, and two surgical procedures that two-flap method and Furlow reverse double Z method were simulated in Ansys, and the area of pharyngeal cavity was measured by hypermesh.

RESULTS

A three-dimensional finite element model of the upper palate, pharyngeal cavity, and bilateral levator veli palatini muscle was established in patients with unilateral complete cleft palate ; The concept of horizontal projection characteristics of the palatal dome was applied to the finite element simulation of cleft palate surgery, vividly simulating the displacement and elastic stretching of the two flap method and Furlow reverse double Z method during the surgical process; The areas with the highest stress in the two-flap method and Furlow reverse double Z method both occur in the hard soft palate junction area; In resting state, as measured, the two flap method can narrow the pharyngeal cavity area by 50.9%, while the Furlow reverse double Z method can narrow the pharyngeal cavity area by 65.4%; The measurement results of the levator veli palatini muscle showed no significant difference compared to previous studies, confirming the accuracy of the model.

CONCLUSIONS

The finite element method was used to establish a model to simulate the surgical procedure, which is effective and reliable. The area with the highest postoperative stress for both methods is the hard soft palate junction area, and the stress of the Furlow reverse double Z method is lower than that of the two-flap method. The anatomical conditions of pharyngeal cavity of Furlow reverse double Z method are better than that of two-flap method in the resting state.

CLINICAL RELEVANCE

This article uses three-dimensional finite element method to simulate the commonly used two-flap method and Furlow reverse double Z method in clinical cleft palate surgery, and analyzes the stress distribution characteristics and changes in pharyngeal cavity area of the two surgical methods, in order to provide a theoretical basis for the surgeon to choose the surgical method and reduce the occurrence of complications.

Two-stage palatal repair in non-syndromic CLP patients using anterior to posterior closure is associated with minimal need for secondary palatal surgery

OBJECTIVE

The aim of the present study was to assess the need for secondary palatal corrective surgery in a concept of palate repair that uses a protocol of anterior to posterior closure of primary palate, hard palate and soft palate.

METHODS

A data base of patients primarily operated between 2001 and 2021 at the Craniofacial and Cleft Care Center of the University Goettingen was evaluated. Cleft lips had been repaired using Tennison Randall and Veau-Cronin procedures in conjunction with alveolar cleft repair. Cleft palate repair in CLP patients was accomplished in two steps with repair of primary palate and hard palate first using vomer flaps at the age of 10-12 months and subsequent soft palate closure using Veau/two-flap procedures 3 months later. Isolated cleft palate repair was performed in a one-stage operation using Veau/two-flap procedures. Data on age, sex, type of cleft, date and type of surgery, occurrence and location of oronasal fistulae, date and type of secondary surgery performed for correction of oronasal fistula (ONF)and / or Velophyaryngeal Insufficiency (VPI) were extracted. The rate of skeletal corrective surgery was registered as a proxy for surgery induced facial growth disturbance.

RESULTS

In the 195 patients with non-syndromic complete CLP evaluated, a total number of 446 operations had been performed for repair of alveolar cleft and cleft palate repair (Veau I through IV). In 1 patient (0,5%), an ONF occurred requiring secondary repair. Moreover, secondary surgery for correction of VPI was required in 1 patient (0,5%) resulting in an overall rate of 1% of secondary palatal surgery. Skeletal corrective surgery was indicated in 6 patients (19,3%) with complete CLP in the age group of 15 - 22 years (n = 31).

CONCLUSIONS

The presented data have shown that two-step sequential cleft palate closure of primary palate and hard palate first followed by soft palate closure has been associated with minimal rate of secondary corrective surgery for ONF and VPI at a relatively low need for surgical skeletal correction.

Differences in velopharyngeal pressures during speech sound production in patients with unilateral cleft lip and palate (UCLP) and healthy individuals

Background

During articulation the velopharynx needs to be opened and closed rapidly and a tight closure is needed. Based on the hypothesis that patients with cleft lip and palate (CLP) produce lower pressures in the velopharynx than healthy individuals, this study compared pressure profiles of the velopharyngeal closure during articulation of different sounds between healthy participants and patients with surgically closed unilateral CLP (UCLP) using high resolution manometry (HRM).

Materials and methods

Ten healthy adult volunteers (group 1: 20-25.5 years) and ten patients with a non-syndromic surgically reconstructed UCLP (group 2: 19.1-26.9 years) were included in this study. Pressure profiles during the articulation of four sounds (/i:/, /s/, /ʃ/ and /n/) were measured by HRM. Maximum, minimum and average pressures, time intervals as well as detection of a previously described 3-phase-model were compared.

Results

Both groups presented with similar pressure curves for each phoneme with regards to the phases described and pressure peaks, but differed in total pressures. An exception was noted for the sound /i:/, where a 3-phase-model could not be seen for most patients with UCLP. Differences in velopharynx pressures of 50% and more were found between the two groups. Maximum and average pressures in the production of the alveolar fricative reached statistical significance.

Conclusions

It can be concluded that velopharyngeal pressures of patients with UCLP are not sufficient to eliminate nasal resonance or turbulence during articulation, especially for more complex sounds. These results support a general understanding of hypernasality during speech implying a (relative) velopharyngeal insufficiency.

Oral flora and functional dysbiosis of cleft lip and palate patients: A scoping review

AIMS

This scoping review aimed to conduct an assessment of the current literature on specific ecological changes in the oral microbiota of individuals living with cleft lip and/or palate.

METHODS

All studies that assess oral microbiota and ecological changes distinct of individuals living with cleft lip and/or palate were included. Ovid MEDLINE and EMBASE databases were used, using planned search keywords. Included articles were grouped into cohort, cross-sectional, case-control, and retrospective reviews.

RESULTS

A total of 164 eligible title articles were recognized. Of these, 32 full-text studies were included in the present review. All the included articles were published between 1992 and 2022. These studies were two retrospective studies, two review studies, and the remaining (n = 28) were observational studies.

CONCLUSION

The oral flora of cleft lip and/or palate patients has been shown in scientific studies to have an increased frequency of potentially pathogenic fungal and bacterial colonization, particularly Candida species, Staphylococcus aureus, Lactobacili and Streptococci mutans. This may influence oral diseases and post-operative repair complications, potentially necessitating further surgical intervention.

Surgical Management of Submucous Cleft Palate by Radical Muscle Dissection Veloplasty: Speech Outcomes in Patients with 22q11.2 Deletion Syndrome

OBJECTIVE

To evaluate the benefit of anatomical muscle dissection repair for velopharyngeal insufficiency (VPI) in patients with submucous cleft palate (SMCP) with 22q11.2 deletion syndrome.

DESIGN

Retrospective blinded randomised analysis of a surgeon's management over 10 years.

SETTING

The study was performed at a specialised Paediatric hospital in the United Kingdom.

PATIENTS

Children with SMCP and 22q11.2 deletion syndrome.

INTERVENTIONS

All participants underwent radical muscle dissection veloplasty.

OUTCOMES MEASURED

Pre- and post- operative measurements included severity of anatomical defect, speech samples and lateral images which were digitised, randomised then externally and blindly analysed using validated techniques. Stata software was used to perform statistical analysis.

RESULTS

57 children with 22q11.2 deletion syndrome were included in this analysis. Intra-operatively, the majority of cases were identified as SMCP Grade I anomalies. Post-operatively, a statistically significant improvement in hypernasality, resting palate length, palate length at maximum closure, palate excursion and gap size at maximum closure was observed. Secondary surgery was performed for 59% of patients by ten years.

CONCLUSION

Muscle dissection repair improves hypernasality, palate closure function and the closure gap in patients with 22q11.2 deletion syndrome. Although over 50% of patients may require further surgery, muscle dissection repair should be a first step due to its utility at a younger age, when invasive investigations are impossible, its lower morbidity, speech and language benefits or altering the plans for less obstructive secondary surgery when it lead to reduced velo-pharyngeal gap and improved palate mobility even when adequate velo-pharyngeal closure was not achieved.

Two-flap technique with interpositional dermofat graft for anterior oronasal fistula closure in patients with cleft: A case series

BACKGROUND

Oronasal fistula at the anterior hard palate is one of the common sequelae after cleft surgery, and the leakage negatively affects the patient's quality of life. Although several surgical techniques have been proposed for reconstruction, it remains challenging because of the scarred regional tissue with a high rate of fistula recurrence. In this study, we present the anterior oronasal fistula repair using a two-flap technique with an interpositional dermofat graft (DFG).

METHODS

A retrospective review of anterior oronasal fistula repair performed by the senior author between April 2018 and August 2022 at the Craniofacial Center was conducted. Patients who underwent a fistula repair using the technique were further identified and investigated.

RESULTS

Thirty-four operations were performed using the technique, and 31 fistulas were completely closed, with a success rate of 91.2%. The fistula symptom improved but persisted postoperatively in 3 patients, of whom 2 patients underwent a second fistula repair using the same procedure, resulting in successful closure. Fistula recurrence was significantly correlated with fistula size (p = 0.04). The DFG was simultaneously utilized for nasal dorsum and/or vermillion reconstruction in 28 cases.

CONCLUSION

The two-flap technique enabled tension-free approximation, and the interpositional DFG facilitated watertight closure of the fistula, resulting in a high success rate of anterior oronasal fistula repair. The fistula closure could be combined with other revisional procedures for cleft-related deformities, where the DFG was simultaneously utilized.

Comparison of two Specialized Cleft Palate Feeders

OBJECTIVE

To evaluate feeding efficiency and weight gain in infants with cleft palate fed using 1 of the 2 specialty feeders.

DESIGN

Retrospective cohort study.

SETTING

Cleft palate clinic in a tertiary pediatric hospital.

PARTICIPANTS

Infants with cleft palate (with or without cleft lip) fed using the Medela SpecialNeeds® Feeder (n = 39) or the Dr. Brown's® Specialty Feeding System (n = 16) and who had documented feeding and growth data available from the time of initial assessment in the first month of life and at subsequent follow-up between 2 and 4 months.

PRIMARY OUTCOME MEASURE

Feeding velocity (mL/min).

SECONDARY OUTCOMES MEASURES

Calorie velocity (kcal/min), weight gain, and complications associated with poor feeding.

RESULTS

No statistically significant differences in feeding or calorie velocities were identified between infants with cleft palate fed with the Medela SpecialNeeds® feeder and those fed with the Dr. Brown's® feeder. Mean weight z-scores by month did not differ significantly between the 2 bottle groups at the time of initial assessment (P = .84) and follow-up (P = .20). Mean weight z-scores by month for the infants included in this study fell below the 50th percentile. The proportion of infants who developed otitis media, reflux requiring treatment, or who required hospital admission for nasogastric (NG) feeds did not differ significantly between the 2 groups.

CONCLUSIONS

Despite being adequately powered for the primary outcome, no significant differences were identified between infants fed with the Medela or the Dr. Brown's feeders in terms of feeding velocity, calorie velocity, weight gain, or complications.

Surgical treatment of velopharyngeal dysfunction: Incidence and associated factors in the Swedish cleft palate population

INTRODUCTION

Speech in children with cleft palate can be affected by velopharyngeal dysfunction, which persists after primary palate repair. The incidence of surgery to correct velopharyngeal dysfunction in this patient group has previously been reported as 2.6-37%. We aimed to investigate the incidence of velopharyngeal dysfunction surgery in Swedish children with cleft palate and to examine potential associations of independent variables with this incidence.

METHODS

In this cohort study, we analysed data from the Swedish cleft lip and palate quality registry for 1093 children with cleft palate with or without cleft lip. Kaplan-Meier analysis was used to estimate the risk of having velopharyngeal dysfunction surgery. Multivariable Cox proportional hazards models were used to estimate the associated effect of cleft subtype, additional diagnoses, gender, and age at and number of stages for primary palate repair on the primary outcome.

RESULTS

The risk of having velopharyngeal dysfunction surgery was 25.6%. Complete primary palate repair after the age of 18 months or in more than one stage was associated with a higher risk, but it could not be determined which of these was the more significant factor. Cleft soft palate was associated with a significantly lower risk than other cleft subtypes.

CONCLUSIONS

Primary palate repair at a higher age or in more than one stage may increase the risk of having velopharyngeal dysfunction surgery. Further analysis of potential unknown confounding factors and the association between the incidence of velopharyngeal dysfunction and surgery to correct this condition is needed.

The Association of Speech/Language Risk With Phonological Awareness, Rapid Naming, and Reading Ability in Children With Cleft Lip and/or Palate

Children with cleft lip and/or palate were assessed for speech, language, phonological awareness (PA), rapid naming (RN) and reading ability using standardized instruments at baseline (T1; N = 142, Mage = 6.14 years, 51% males) and 2-year follow-up (T2; 89% retention, Mage = 8.38). Children with no speech or language risk scored higher for T1 and T2 PA, RN, and reading than children with both speech and language risk [Adjusted Mean Difference (AMD) ranged from 11.79 to 21.25]; language risk (AMD 8.37 to 13.58); and speech risk (0.51 to 6.87). No significant differences by cleft type or child sex.

Arthrogryposis multiplex congenita: dental and maxillofacial phenotype - A scoping review

INTRODUCTION

Arthrogryposis multiplex congenita (AMC) is a heterogeneous group of disorders associated with decreased fetal movement, with a prevalence between 1/3000 and 1/5200 live births. Typical features of AMC include multiple joint contractures present at birth, and can affect all joints of the body, from the jaw, and involving the upper limbs, lower limbs and spine. The jaws may be affected in 25 % of individuals with AMC, with limited jaw movement and mouth opening. Other oral and maxillofacial deformities may be present in AMC, including cleft palate, micrognathia, periodontitis and delayed teething. To our knowledge, oral and maxillofacial abnormalities have not been systematically assessed in individuals with AMC. Therefore, this scoping review was conducted to identify, collect, and describe a comprehensive map of the existing knowledge on dental and maxillofacial involvement in individuals with AMC.

METHODOLOGY

A scoping review was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines. The PRISMA guidelines for scoping reviews were followed and databases were searched for empirical articles in English and French published until October 2022. We searched MEDLINE, Embase, Web of Science and ERIC databases. Two authors independently reviewed the articles and extracted the data.

RESULTS

Of a total of 997 studies that were identified, 96 met the inclusion criteria and were subsequently included in this scoping review. These 96 studies collectively provided insights into 167 patients who exhibited some form of oral and/or maxillofacial involvement. Notably, 25 % of these patients were within the age range of 0-6 months. It is worth highlighting that only 22 out of the 96 studies (22.9 %), had the primary objective of evaluating dental and/or maxillofacial deformities. Among the patients studied, a prevalent pattern emerged, revealing that severe anomalies such as micrognathia (56 %), high-arched palate (29 %), cleft palate (40 %), limited mouth opening (31 %), and dental anomalies (28 %) were frequently observed. Importantly, many of these patients were found to have more than one of these anomalies. Even though these maxillofacial impairments are known to be associated with dental problems (e.g., cleft palate is associated with oligodontia, hypodontia, and malocclusion), their secondary effects on the dental phenotype were not reported in the studies.

CONCLUSION

Our findings have uncovered a notable deficiency in existing literature concerning dental and maxillofacial manifestations in AMC. This underscores the need for interdisciplinary collaboration and the undertaking of extensive prospective cohort studies focused on AMC. These studies should assess the oral and maxillofacial abnormalities that can impact daily functioning and overall quality of life.

Chikungunya virus antepartum transmission and abnormal infant outcomes in a cohort of pregnant women in Nigeria

OBJECTIVES

Chikungunya virus (CHIKV), a reemerging global public health concern, which causes acute febrile illness, rash, and arthralgia and may affect both mothers and infants during pregnancy. Mother-to-child transmission (MTCT) of CHIKV in Africa remains understudied.

METHODS

Our cohort study screened 1006 pregnant women with a Zika/dengue/CHIKV rapid test at two clinics in Nigeria between 2019 and 2022. Women who tested positive for the rapid test were followed through their pregnancy and their infants were observed for 6 months, with a subset tested by reverse transcription-polymerase chain reaction (RT-PCR) and neutralization, to investigate seropositivity rates and MTCT of CHIKV.

RESULTS

Of the 1006, 119 tested positive for CHIKV immunoglobulin (Ig)M, of which 36 underwent detailed laboratory tests. While none of the IgM reactive samples were RT-PCR positive, 14 symptomatic pregnant women were confirmed by CHIKV neutralization test. Twelve babies were followed with eight normal and four abnormal outcomes, including stillbirth, cleft lip/palate with microcephaly, preterm delivery, polydactyly with sepsis, and jaundice. CHIKV IgM testing identified three possible antepartum transmissions.

CONCLUSION

In Nigeria, we found significant CHIKV infection in pregnancy and possible CHIKV antepartum transmission associated with birth abnormalities.

The Periodontal Status of Orofacial Cleft Patients: A Systematic Review and Meta-Analysis

Cleft lip and/or palate is the most commonly documented orofacial anomaly and may impact the status of health and disease of adjacent teeth along with their associated supporting structures. The authors performed a systematic review and meta-analysis to assess whether the presence of clefts altered the periodontal status of patients.

The study was registered in PROSPERO (CRD42020210178). A systematic search of literature was performed utilizing unique search strings for PubMed, Scopus, and GoogleScholar as databases including gray literature from April 28, 2020 to October 3, 2020.

Cross-sectional and longitudinal human studies published in the English language, providing information about periodontal disease and its association with cleft lip, alveolus, and palate.

Periodontal outcome measures such as gingival index (GI), clinical attachment level (CAL), plaque index (PI), periodontal probing depth (PPD), and bleeding on probing (BOP) were utilized as the main outcome measures.

Patients with clefts were predisposed to poorer periodontal outcomes. Subgroup analysis revealed compromised periodontal measures for clefts as compared to control sites without cleft which were statistically significant in terms of GI [Z = 2.44, P = .01], CAL [Z = 2.52, P = .01], PI [Z = 2.76, P = .006] and not statistically significant for PPD [Z = 0.27, P = .79] and BOP [Z = 1.47, P = .14].

Within the limitations of the review, the authors conclude that the presence of orofacial clefts may predispose to periodontal compromise when compared to normal controls. The GRADE rating was moderate.

Correlation of Dental Anomalies with Cleft Type and Gender in Non-Syndromic Oral Cleft Patients: A Cross-Sectional Study

To investigate the distribution of dental anomalies between non-syndromic orofacial cleft patients and their association with the cleft type and gender.

Retrospective cross-sectional study involving examination of intraoral dental records and radiographs.

300 non-syndromic orofacial cleft patients included (161 males and 139 females, mean age: 10.23 ± 2.3 years).

Variables analyzed: tooth agenesis, microdontia, and supernumerary teeth. Data analysis: Chi-square and Fisher's exact tests to investigate the correlation between dental anomalies, cleft type, and gender.

Agenesis occurred in 66% of the subjects, supernumerary teeth in 19.6%, and microdontia in 18.3%. In females with unilateral left cleft lip and palate (CLP), agenesis was significantly higher compared to males. Both genders presented significant agenesis of maxillary lateral incisors and right central incisor. Significant agenesis of central incisor, canine and second premolar on the upper left side and lower second premolars were observed only in males, with significant microdontia for maxillary lateral incisors and left central incisor. Significant agenesis of maxillary first premolars was seen only in females. Agenesis in maxillary quadrants was significant for patients with unilateral right and left CLP, and bilateral CLP. In mandibular quadrants, agenesis was substantially higher for patients with isolated CP.

Results suggest that tooth agenesis and microdontia might not be directly associated with the cleft area's anatomical irregularity but are affected by gender and other genetic factors that regulate the development of the anomaly and the orofacial clefting mutually.

Modified Medial Incision Small Double-Opposing Z-Plasty for Treating Veau Type I Cleft Palate: Is the Early Result Reproducible?

OBJECTIVE

An inspiring early result with no oronasal fistula formation was recently described for a modified medial incision small double-opposing Z-plasty (MIsDOZ) for treating Veau type I cleft palate. This study describes an early single-surgeon experience in applying this newly proposed surgical approach.

DESIGN

Retrospective single-surgeon study.

PATIENTS

Consecutive nonsyndromic patients (n  =  27) with Veau I cleft palate.

INTERVENTIONS

Topographic anatomical-guided MIsDOZ palatoplasty with pyramidal space dissection (releasing of the ligamentous fibers in the greater palatine neurovascular bundle and pyramidal process region, in-fracture of the pterygoid hamulus, and widening of space of Ernst) performed by a novice surgeon (RD).

MEAN OUTCOME MEASURES

Age at surgery, the presence of cleft lip, palatal cleft width, use of lateral relaxing incision, and 6-month complication rate (bleeding, dehiscence, fistula, and flap necrosis). A published senior surgeon-based outcome dataset (n  =  24) was retrieved for comparison purposes.

RESULTS

Twenty-two (81.5%) and 5 (18.5%) patients received the medial incision only technique and lateral incision technique, respectively (P  =  .002). Age, presence of cleft lip, and cleft width were not associated (all P > .05) with the use of lateral incision. Comparative analysis between the novice surgeon- and senior surgeon-based datasets revealed no significant differences for sex (females: 74.1% vs 62.5%; P  =  .546), age (10.2  ±  1.7 vs 9.6  ±  1.2 months; P  =  .143), rate of lateral incision (18.5% vs 4.2%; P  =  .195), and postoperative complication rate (0% vs 0%).

CONCLUSION

This modified DOZ palatoplasty proved to be a reproducible procedure for Veau I cleft palate closure, with reduced need for lateral incision and with no early complication.

Unilateral Cleft lip and Palate: Long-Term Results of the Malek Technique

To review at 18 years-old the results of surgery and follow-up of children born in our hospital with unilateral cleft lip and palate (uCLP). They were operated at the time by the same surgeon, following the same primary surgical procedure (Malek).

Retrospective cohort study.

Tertiary Children's Hospital.

All children born with uCLP between 1996 and 2001 and operated in our hospital. Syndromic children were excluded.

Results of the primary surgery, ear-nose-throat interventions, maxillo-facial surgery and final phonatory results.

Seventy-nine files of children born with a cleft were reviewed: 34 were taken into consideration for uCLP: 15 right and 19 left. They were operated in two stages, following the inverse Malek procedure. Sixty per cent had a fistula. Eighty-eight percent had grommets. Ninety-seven percent had an alveolar graft at a median age of nine (5-10) and 22% underwent a Le Fort osteotomy. Seven percent were operated for a pharyngeal flap, 29% for a secondary lip surgery at a mean age of 12.8 and 29% for a late rhinoplasty at a mean age of 14.8 years. A median of 5.7 multidisciplinary consultations was realized with a median number of general anesthesia of 7.1 (4-13).

This retrospective study shows that the Malek procedure for children born with uCLP is related to a high risk of fistula but good long-term phonatory results. Twenty percent of children were operated for a Le Fort procedure and one-third for a secondary lip procedure and rhinoplasty.

Proposed clinical model for predicting speech outcomes in patients undergoing Furlow palatoplasty for velopharyngeal insufficiency after primary palatoplasty

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.

Do Adult Naïve Listeners Perceive Differences in Speech Before and After Therapy for Cleft Palate Speech Disorders? A Reliability Study of Perceptual Speech Ratings

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.

Dental Rehabilitation of the Unilateral Cleft Dental Gap: A Single Institution Experience With Long-Term Follow-Up

OBJECTIVE

The purpose of this study was to identify factors associated with the management of the cleft dental gap after alveolar bone grafting.

METHODS

This was a retrospective cohort study of patients with unilateral cleft lip and alveolus or palate who had successful alveolar bone grafting. Our primary study outcome was alveolar cleft management (orthodontic closure or space maintenance). Our secondary study outcome was the rate of fixed dental rehabilitation. Univariate comparisons were made with SAS 9.4.

RESULTS

The final study sample consisted of 54 patients. Most patients were treated with orthodontic closure (55.6%). Patients missing multiple teeth ( P < 0.01) were less likely to receive orthodontic closure. Orthodontic closure was not associated with differences in intermaxillary midline coincidence ( P = 0.22) or the need for LeFort advancement ( P = 0.15). Only 41.7% of patients who were managed with space maintenance obtained a fixed prosthesis. Hispanic ethnicity ( P < 0.01) and Medicaid insurance ( P < 0.01) were associated with lower rates of fixed dental rehabilitation.

CONCLUSIONS

Orthodontic closure was the most common approach, and it did not result in significant maxillary midline distortion. Less than half of patients treated with space maintenance obtained fixed restorations. Socioeconomic barriers are likely preventing access to definitive dental rehabilitation in patients with unilateral cleft lip and alveolus or palate.

Risk of orofacial clefts in relation to maternal body mass index, diabetes and hypertension

BACKGROUND

To investigate if maternal body mass index, diabetes and hypertension are associated with orofacial clefts.

METHODS

Case-control study. Information from 53,188 live births with and without orofacial cleft registered at USA Vital Statistics Natality Birth Data between 2017 and 2021. Case group consisted of all affected live births diagnosed with orofacial clefts (13,297 cases). Comparison group consisted of 39,891 live births without clefts or any other congenital malformation. Information about orofacial cleft cases were compared with the comparison group. The unadjusted and adjusted Odds Ratios were estimated to evaluate the strength of association between mother's pre-pregnancy body mass index, maternal diabetes and hypertension and orofacial cleft occurrence, assuming a p value < 0.05 and 95% confidence intervals (95% C.I.) for statistically significant differences.

RESULTS

Mother's pre-pregnancy body mass index, maternal diabetes and maternal hypertension are conditions associated with an increased risk of orofacial cleft development in the child (OR = 1.08, p = 0.004, 95% C.I. = 1.024-1.149; OR = 1.32, 95%, p = 0.000, 95% C.I. = 1.202-1.444; and OR = 1.35, p = 0.000, 95% C.I. = 1.239-1.484; respectively). Maternal ethnicity, sex of infant, and cigarette smoking pregnancy remained as covariates after adjustments in all logistic regression models.

CONCLUSION

Due to the increased prevalence of obesity, diabetes, and hypertension, and also to their association with congenital malformations, such as clefts, it is recommended that mothers planning to become pregnant to follow healthy habits, maintain healthy weight, and be screened for possible diabetes or hypertension prior to conception and early in pregnancy.

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.

Do Buccal Flaps Improve Velopharyngeal Insufficiency in Conversion Furlow Palatoplasty for Patients with Cleft Palate?

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.

Anatomical Study of Domain Rescue of Palatal Length in Patients With a Wide Cleft Palate: Buccal Flap Reconstruction in Primary Palatoplasty

BACKGROUND

This study characterizes the potential loss of velar length in patients with a wide cleft and rescue of this loss of domain by local flap reconstruction, providing anatomic evidence in support of primary lengthening of the soft palate during palatoplasty.

METHODS

A retrospective review was conducted of all patients with a cleft palate at least 10mm in width, who underwent primary palatoplasty with a buccal flap prior to 18 months of age over a 2-year period. All patients underwent primary palatoplasty with horizontal transection of the nasal mucosa, which was performed after nasal mucosa repair, but prior to muscular reconstruction. The resulting palatal lengthening was measured and the mucosal defect was reconstructed with a buccal flap.

RESULTS

Of the 22 patients included, 3 (13.6%) had a history of Pierre Robin sequence, and 5 (22.7%) had an associated syndrome. No patients had a Veau I cleft, 7 (31.8%) had a Veau II, 12 (54.5%) had a Veau III, and 3 had (13.6%) a Veau IV cleft. All patients had a right buccal flap during primary palatoplasty. The mean cleft width at the posterior nasal spine was 10.6  ±  2.82mm, and mean lengthening of the velum after horizontal transection of the nasal mucosa closure was 10.5  ±  2.23mm. There were 2 (9.1%) fistulas, 1 (4.5%) wound dehiscence, 1 (4.5%) 30-day readmission, and no bleeding complications.

CONCLUSIONS

Patients with a wide cleft palate have a potential loss of 1cm velar length. The buccal flap can rescue the loss of domain in palatal length, and potentially improve palatal excursion.

Long-term outcomes of sphincter pharyngoplasty in patients with cleft palate

OBJECTIVE

The purpose of this study was to evaluate long-term outcomes of sphincter pharyngoplasties, including speech outcomes, revision surgeries, and postoperative incidence of obstructive sleep apnea (OSA).

DESIGN

Retrospective matched-cohort study SETTING: Two craniofacial centers in Los Angeles, CA PATIENTS: Patients (n = 166) with cleft lip and palate (CLP) or isolated cleft palate (iCP) who underwent sphincter pharyngoplasty from 1992 to 2022 were identified. An age- and diagnosis-matched control group of 67 patients with CLP/iCP without velopharyngeal insufficiency (VPI) was also identified.

INTERVENTIONS

The pharyngoplasty group underwent sphincter pharyngoplasty, whereas the non-VPI group had no history of VPI surgery or sphincter pharyngoplasty.

MAIN OUTCOME MEASURES

Postoperative speech outcomes, revision surgeries, and incidence of OSA were evaluated. Multivariable regression was used to evaluate independent predictors of OSA.

RESULTS

Among the patients in the pharyngoplasty cohort, 63.9% demonstrated improved and sustained speech outcomes after a single pharyngoplasty, with a median postoperative follow-up of 8.8 years (interquartile range [IQR], 3.6-12.0 years). One-third of the patients who underwent pharyngoplasty required a revision surgery, with a median time to primary revision of 3.9 years (IQR, 1.9-7.0 years). OSA rates increased significantly among the pharyngoplasty cohort, from 3% before surgery to 14.5% after surgery (p < 0.001). The average time from sphincter pharyngoplasty to OSA diagnosis was 4.4 ± 2.4 years. Multivariable analysis results indicated that sphincter pharyngoplasty surgery was independently associated with a fourfold increase in OSA (p = 0.03).

CONCLUSIONS

Although sphincter pharyngoplasty remains successful in improving long-term speech outcomes, persistent OSA is a sequela that should be monitored beyond the immediate postoperative period.

Evaluation of the effect of palatoplasty on the quality of life and speech outcomes in patients with velocardiofacial syndrome

BACKGROUND

Children diagnosed with velocardiofacial syndrome (VCFS) suffer from various disabilities. Palatal abnormalities, as well as speech and language impairment, adversely affect a child's quality of life (QoL) and are some of the most distressing aspects for the parents of these children.

OBJECTIVES

The present study aimed to explore the effect of palatoplasty on the health-related quality of life (HRQoL) and speech outcomes in children with VCFS.

MATERIAL AND METHODS

The study recruited 20 patients (N = 20) with VCFS and connected speech, aged 3 years or older, having either undiagnosed submucous cleft palate (SMCP) or velopharyngeal insufficiency (VPI), and requiring primary cleft palate surgery or revision surgery. Speech assessment was conducted prior to palatoplasty and 6 months after the surgery. Intelligibility and hypernasality were evaluated using the Cleft Audit Protocol for Speech - Augmented (CAPS-A). The parent proxy-report form of the Pediatric Quality of Life Inventory (PedsQL™) was used to evaluate and compare the HRQoL of the VCFS patients before and after palatoplasty.

RESULTS

Significant improvement in the HRQoL scores was achieved after the surgery across all domains (physical, emotional, social, and school functioning), especially in the emotional and social dimensions (p < 0.000). The post-operative speech assessment based on CAPS-A demonstrated improvement in speech intelligibility and hypernasality in the majority of patients.

CONCLUSIONS

Given that children with VCFS face various medical and social problems, suitable palatal interventions are beneficial, improving both the speech ability and QoL of these children.

Case report: Pai syndrome with multiple ventricular septal defect and without cleft palate

Pai syndrome is described as the association of a midline cleft lip, midline facial polyps, and lipoma of the central nervous system. However, only a few patients present the full triad, and most exhibit a wide spectrum of phenotypic variability. Its entire clinical spectrum is still poorly delineated and the etiology remains unknown. In this report, a newborn was presented with congenital nasal septal lipoma, lipoma of the corpus callosum, multiple ventricular septal defect, and additional minor facial dysmorphism. This entity, multiple ventricular septal defect, which has never been reported in PS. Cytogenetic analysis showed normal male 46, XY karyotype. Chromosomal microarray analysis (750 K array) was also unremarkable. This case draws attention with the presence of multiple ventricular septal defect in Pai syndrome and is important in terms of providing phenotypic diversity. To our knowledge, this is also the first genetically evaluated case of Pai syndrome from Turkey.

Outcome of Nasal Layer Reinforcement With Autologous Dermis in Cleft Palate Repair on Postoperative Fistula Formation

Palatal fistulae are challenging complications following cleft palate repair. The addition of acellular dermal matrix (ADM) to cleft palate repair has been shown to reduce fistula formation in previous studies. The use of autologous dermal graft has all the structural advantages of ADM, has less rejection and immunogenic potential, and is cost effective.

A prospective study.

Patients with Group II and III cleft palate (Nagpur Classification) without prior intervention for palatal repair in the Department of Plastic Surgery at PGIMER from January 2020 till June 2021.

The addition of autologous dermal graft for palatoplasty.

Outcome of the study was fistula development or exposure of dermal graft.

Autologous dermal graft was harvested of average dimension of 8.73 cm2 (range 5.25-18 cm2) from groin region. Sixteen patients were included in the study. Among them, 2 patients (12.5%) developed postoperative fistula (Type III &V Pittsburgh Classification).

Our study showed that the rates of postoperative fistula formation are comparable with prior literature using artificial dermal matrices.

Velopharyngeal insufficiency, speech, and language impairment in craniofacial microsomia: a scoping review

This review provides a comprehensive overview of the literature on velopharyngeal insufficiency, associated anomalies, and speech/language impairment in patients with craniofacial microsomia (CFM). A systematic search of the literature was conducted to identify records on VPI and speech impairment in CFM from their inception until September 2022 within the databases Embase, PubMed, MEDLINE, Ovid, CINAHL EBSCO, Web of Science, Cochrane, and Google Scholar. Seventeen articles were included, analysing 1,253 patients. Velopharyngeal insufficiency results in hypernasality can lead to speech impairment. The reported prevalence of both velopharyngeal insufficiency and hypernasality ranged between 12.5% and 55%, while the reported prevalence of speech impairment in patients with CFM varied between 35.4% and 74%. Language problems were reported in 37% to 50% of patients. Speech therapy was documented in 45.5% to 59.6% of patients, while surgical treatment for velopharyngeal insufficiency consisted of pharyngeal flap surgery or pharyngoplasty and was reported in 31.6% to 100%. Cleft lip and/or palate was reported in 10% to 100% of patients with CFM; these patients were found to have worse speech results than those without cleft lip and/or palate. No consensus was found on patient characteristics associated with an increased risk of velopharyngeal insufficiency and speech/language impairment. Although velopharyngeal insufficiency is a less commonly reported characteristic of CFM than other malformations, it can cause speech impairment, which may contribute to delayed language development in patients with CFM. Therefore, timely recognition and treatment of speech impairment is essential.

Long-term radiographic and periodontal evaluations of the bone-grafted alveolar cleft region in young adults born with a UCLP

BACKGROUND

Studies addressing the periodontal health of the teeth surrounding the bone-grafted cleft in patients born with unilateral cleft lip and palate disagree on whether periodontal health is compromised.

OBJECTIVES

To determine periodontal health differences between the cleft and the non-cleft sides nearly a decade after secondary alveolar bone grafting.

METHODS

This prospective, controlled (split-mouth design) study comprised an intraoral apical radiographic and a periodontal examination of 40 consecutive patients from one centre (n = 26 males) who had undergone bone grafting at mean age of 10.2 years (±1.6). Probing pocket depth, gingival index, gingival recession, and radiographic bone support were assessed.

RESULTS

No significant difference occurred in probing pocket depth between teeth at cleft and non-cleft sites (OR 1.8, P = .488). Gingival recession was present at 6.6% of all examined sites on the cleft side and at 1.7% on the non-cleft side (OR 17.3, P < .001). Gingival recession occurred most often on the buccal and disto-buccal surfaces of the central incisor on the cleft side. The gingival index was significantly higher on the cleft side (OR 8.0, P < .001). The Bergland index was I or II in most patients (87%).

LIMITATIONS

Recruitment of eligible patients was lengthy.

CONCLUSION

The teeth on the cleft side had high levels of gingival inflammation. Few pathological gingival pockets, however, were found. Shallow gingival recessions frequently occurred around the central incisor on the cleft side. Teeth in the bone-grafted cleft region generally had good bone support.

Anaesthetic management of an infant with cleft palate lateral synechiae syndrome

An infant with restricted mouth opening from birth had presented for cleft lip repair. He had an interalveolar gap of 6 mm and was diagnosed as a case of cleft palate lateral synechiae syndrome. Fibreoptic bronchoscope of appropriate size was not available at the time of the procedure, and we had to device an alternative plan. The case describes the common challenges that can arise while anaesthetising infants with this syndrome in a resource-limited setting and highlights the importance of adapting the protocol to the demands.

What is the optimal assessment of speech? A multicentre, international evaluation of speech assessment in 2500 patients with a cleft

OBJECTIVES

Speech problems in patients with a cleft palate are often complex and multifactorial. Finding the optimal way of monitoring these problems is challenging. The International Consortium of Health Outcomes Measurement (ICHOM) has developed a set of standardised outcome measures at specific ages for patients with a cleft lip and/or palate, including measures of speech assessment. This study evaluates the type and timing of speech outcome measures currently included in this ICHOM Standard Set. Additionally, speech assessments in other cleft protocols and initiatives are discussed.

DESIGN, SETTING AND PARTICIPANTS

An international, multicentre study was set up including centres from the USA and the Netherlands. Outcomes of clinical measures and Patient Reported Outcome Measures (PROMs) were collected retrospectively according to the ICHOM set. PROM data from a field test of the CLEFT-Q, a questionnaire developed and validated for patients with a cleft, were collected, including participants from countries with all sorts of income statuses, to examine the value of additional moments of measurement that are used in other cleft initiatives.Data from 2500 patients were included. Measured outcomes contained univariate regression analyses, trend analyses, t-tests, correlations and floor and ceiling effects.

RESULTS

PROMs correlated low to moderate with clinical outcome measures. Clinical outcome measures correlated low to moderate with each other too. In contrast, two CLEFT-Q Scales correlated strongly with each other. All PROMs and the Percent Consonants Correct (PCC) showed an effect of age. In patients with an isolated cleft palate, a ceiling effect was found in the Intelligibility in Context Scale.

CONCLUSION

Recommendations for an optimal speech outcome assessment in cleft patients are made. Measurement moments of different cleft protocols and initiatives are considered in this proposition. Concerning the type of measures, adjustment of the current PCC score outcome seems appropriate. For centres with adequate resources and specific interest in research, translation and validation of an upcoming tool, the Cleft Audit Protocol for Speech Augmented, is recommended.

Analysis of risk factors affecting poor wound healing after primary cleft palate surgery

OBJECTIVES

To study the risk factors of poor wound healing after primary cleft palate surgery.

METHODS

In this study, 980 cases of congenital cleft palate treated by Sommerlad-Furlow in the Department of Cleft Lip and Palate Surgery of Sichuan University from 2017 to 2021 were continuously analyzed. Indicators included patient's age, gender, body weight, cleft palate type, width of the widest fistula, cleft palate index (width of the widest fistula/width at the posterior edge of the maxillary tubercle plane), preoperative white blood cell count, preoperative hemoglobin level, preoperative antibiotic use, doctor's seniority, use of relaxation incision, operation time, postoperative upper respiratory tract infection, and postoperative wound healing. The postoperative wound healing was divided into normal healing, delayed healing, and palatal fistula. Both delayed healing and palatal fistula were classified as poor healing. The factors that may affect the healing outcome of the palatal wound after primary cleft palate repair were analyzed using SPSS 26.0 software.

RESULTS

A total of 825 patients (84.2%) had normal healing, 112 patients (11.4%) had delayed hea-ling, and 43 patients (4.4%) had palatal fistula. Doctor's seniority, width of the widest fissure, cleft palate index, and operation time influenced the wound healing effect after cleft palate surgery (P<0.05). Doctors with low seniority, wide width of the widest fistula, large cleft palate index, and long operation time were the risk factors of poor wound healing.

CONCLUSIONS

Doctor's seniority, width of the widest fissure, cleft palate index, and operation time are related to the effect of healing effect after cleft palate surgery.

A Rare Case of Cleft Palate Associated With Tongue Hamartoma: A Case Report and Systematic Review

INTRODUCTION

Palate development involves a genetic regulation through a complex molecular mechanism that may be disrupted by environmental factors, resulting in impaired fusion and cleft palate formation. An encounter with a case of cleft palate due to dorsal tongue hamartoma prompted us to perform this systematic review.

OBJECTIVE

To review the clinical profile and management approach for a case with cleft palate and tongue hamartoma.

DESIGN

A systematic literature search was conducted using keywords related to cleft palate and tongue hamartoma in PubMed, Scopus, MEDLINE, and Scielo databases through December 2021, with no time or language restrictions.

PATIENTS, PARTICIPANTS

Studies reporting patients with cleft palate and tongue hamartoma were included.

MAIN OUTCOME MEASURE(S)

Information related to clinical profile, diagnostic tests, histopathology, management, and outcomes were extracted.

Fourteen relevant publications were identified with 16 cases reported so far. Among them, thirteen patients were females (81.25%), and 3 were males (18.75%). The age of presentation varied from birth to 19 years. Oral-facial-digital syndrome (type II) was the most commonly associated syndrome.

Congenital tongue hamartoma with cleft palate is a rare presentation, which can present as an isolated entity or part of a syndrome. Genetic evaluation is warranted, particularly for multiple hamartomatous lesions. The preferred treatment is immediate excision of hamartoma while following a standard timeline for palatoplasty.

Catch-Up Growth Pattern in Cleft Palate: A Longitudinal Study from Infancy to Adolescence

OBJECTIVE

To characterize the patterns of somatic catch-up growth from infancy to adolescence in patients with cleft palate (CP).

STUDY DESIGN

We assessed 474 nonsyndromic patients with isolated cleft palate (n = 69) and unilateral and bilateral cleft lip and palate (n = 271; n = 134) who underwent palatoplasty between 1988 and 2017 and had longitudinal physical growth data at birth (T0), cheiloplasty (T1), palatoplasty (T2), childhood (T3), and adolescence (T4). The z scores of weight (ZWT), height (ZHT), and body mass index (ZBMI) were compared among the CP types (isolated cleft palate, unilateral cleft lip and palate, and bilateral cleft lip and palate) and time points (T1, T2, T3, and T4). Subgroup analyses were performed to investigate the growth of patients with malnourishment (z score < -1) at T1 or T2. A generalized linear model was used to investigate the effects of gestational age and cardiac anomalies on the longitudinal changes in ZHT and ZBMI.

RESULTS

Regardless of the time point, the overall ZHT, ZWT, and ZBMI approximated 0 in all CP types, indicating few differences from the mean values of noncleft children. Significant catch-up growth occurred in ZHT and ZWT from T1 to T4 for all CP types (all P < .05). Despite the recovery of ZHT and ZBMI in most patients with malnourishment, these values remain relatively low until adolescence. Patients who were born at preterm stage or had surgically repaired cardiac anomalies grew well.

CONCLUSIONS

Even in infants with CP and malnutrition, preterm birth, or cardiac anomalies, rapid catch-up growth can occur prior to palatoplasty with the help of comprehensive cleft care.
