Abstract Background The aims of this study were to perform a four-dimensional assessment of velopharyngeal closure function in pediatric patients with cleft palate using 320-row area detector computed tomography (CT), and to estimate the organ-absorbed doses using Monte Carlo simulation. Methods We evaluated CT image data obtained between July 2018 and August 2019 from five pediatric patients with cleft palate (four boys and one girl; age range, 4–7 years) at Fujita Health University Hospital. The presence of velopharyngeal insufficiency (VPI), patterns of velopharyngeal closure (VPC), and cross-sectional area of VPI were evaluated. In addition, organ-absorbed doses were assumed in the Monte Carlo simulation. However, we did not perform statistical analysis because of the insufficient number of patients enrolled in this study. Results The existence of VPI and hypernasality were completely concordant. The VPC patterns were circular (two patients), circular with Passavant’s ridge (one patient), and unevaluable (two patients). The organ-absorbed doses were relatively lower than those in past reports. Conclusions Our method could be an alternative for patients who refuse the conventional nasopharyngoscopic evaluation.

Objective This study was designed to determine whether velar surgery was worthwhile for submucous cleft palate (SMCP) and evaluate whether results were dependent on the degree of the anatomical abnormality. Design A prospective study of a consecutive series of patients fulfilling the entry criteria, assessed blindly from records arranged randomly. Patients Fifty-eight patients diagnosed with SMCP and operated on by a single surgeon between June 1991 and April 1997 were reviewed. Forty patients fulfilled the entry criteria. Minimum follow-up was 6 years. Interventions Radical reconstruction of the soft palate musculature was performed by one surgeon using the operating microscope. A scoring system was devised for grading the anatomical severity of submucous cleft (SMCP score). Main Outcome Measures Postoperative hypernasality and nasal emission scores and the degrees of improvement were considered the primary outcome measures, and the degree of velopharyngeal closure was also assessed. Results There were highly significant improvements in hypernasality, nasal emission, and velopharyngeal closure. A preoperative gap size of more than 13 mm was associated with less satisfactory outcomes, but gap size was not predictive of improvement. Severity of the SMCP did not correlate with the degree of preoperative speech abnormality but was a significant predictor of outcome of surgery, with the less severe (total SMCP score of 0 to 3) having less satisfactory end results and lesser degrees of improvement. Patients with less abnormal muscle anatomy had lesser degrees of improvement. Conclusion Repair of the muscle abnormality in SMCP is recommended as the first line of treatment in most cases.

Objective: Some patients with cleft palate (CP) need secondary surgery to improve functionality. Although 4-dimensional assessment of velopharyngeal closure function (VPF) in patients with CP using computed tomography (CT) has been existed, the knowledge about quantitative evaluation and radiation exposure dose is limited. We performed a qualitative and quantitative assessment of VPF using CT and estimated the exposure doses. Design: Cross-sectional. Setting: Computed tomography images from 5 preoperative patients with submucous CP (SMCP) and 10 postoperative patients with a history of CP (8 boys and 7 girls, aged 4-7 years) were evaluated. Patients: Five patients had undergone primary surgery for SMCP; 10 received secondary surgery for hypernasality. Main Outcome Measures: The presence of velopharyngeal insufficiency (VPI), patterns of velopharyngeal closure (VPC), and cross-sectional area (CSA) of VPI was evaluated via CT findings. Organ-absorbed radiation doses were estimated in 5 of 15 patients. The differences between cleft type and VPI, VPC patterns, and CSA of VPI were evaluated. Results: All patients had VPI. The VPC patterns (SMCP/CP) were evaluated as coronal (1/4), sagittal (0/1), circular (1/2), and circular with Passavant’s ridge (2/2); 2 patients (1/1) were unevaluable because of poor VPF. The CSA of VPI was statistically larger in the SMCP group ( P = .0027). The organ-absorbed radiation doses were relatively lower than those previously reported. Conclusions: Four-dimensional CT can provide the detailed findings of VPF that are not possible with conventional CT, and the exposure dose was considered medically acceptable.

Abstract Background Submucous cleft palate (SMCP) is a congenital abnormality with various clinical and anatomical features. Submucous cleft pathologies may be unrecognized during routine examinations. Current diagnostic techniques are constrained and unrevealing in presurgical patients. This prospective study aimed to evaluate transnasal palatal transillumination technique in diagnosis of SMCP at our institute hospital, during period from 2005-2020. Patients and methods Twenty-one cases with SMCP were recruited with age range from 2-60 months. Transnasal palatal transillumination with controllable light intensity endoscope used to evaluate SMCP and cases were photo and video recorded. Results In this study, 21 cases (13 males and 8 females) with SMCP were detected or confirmed by intranasal transnasal palatal transillumination. Frequency of SMCP patients at our institute was 3.39%. All patients presented with symptomatic complaints at diagnosis time, apart from 5 patients (23.8%) were diagnosed during cleft lip repair operations. Presenting symptoms were hypernasality (23.8%), delayed speech (23.8%), perforated palate with nasal escape of milk and food (14.3%), feeding difficulties (14.3%), and otitis media (4.8%). During intra-oral examination, all cases had a bifid uvula accompanied SMCP. Submucous cleft palate appeared as thin palate with central lucency. According to operative findings, operations done for repair were mostly two long palatal flaps (n = 13, 61.9%), von Langenbeck (n = 5, 23.8%), simple repair with lateral release incisions (n = 2, 9.6%), and simple repair without lateral release incision (n = 1, 4.8%). Conclusions Intraoperative assessment of submucous cleft palate with transnasal palatal transillumination is easy and cheap method to avoid missing cases of SMCP.

Summary Background/Objectives This retrospective study evaluated the prevalence of dental anomalies of number in different subphenotypes of isolated cleft palate. Materials/Methods The sample comprised 26 individuals with submucous cleft palate (group S) and 68 individuals with complete cleft palate (group C) aged between 9 and 12 years from a single centre. Panoramic radiographs were evaluated regarding the presence of dental anomalies of number in permanent teeth. Intergroup comparison was performed using chi-square tests (P < 0.05). Results Tooth agenesis was found in 34.61 and 36.76 per cent of group S and group C, respectively. The most commonly missing teeth were the maxillary second premolar, maxillary lateral incisor, and mandibular second premolar. Supernumerary teeth were found in none and 1.47 per cent of the individuals with submucous and complete cleft palate, respectively. No statistically significant difference was found between groups for the frequency of tooth agenesis and supernumerary teeth. Limitations Only dental anomalies of number were evaluated. Conclusions/Implications Individuals with submucous and complete cleft palate showed similar prevalence for tooth agenesis and supernumerary teeth. Dental anomalies frequency seems not to be a discriminator for subphenotypes of cleft palate.
