ABSTRACT: Context
Videofluoroscopy in operated cleft palate patients.Aims
To determine the existence of an optimal resting velopharyngeal (VP) gap in operated cleft palate patients.Settings and design
A retrospective analysis of lateral view videofluoroscopy of operated cleft palate patients.Materials and methods
A total of 117 cases of operated cleft palate underwent videofluoroscopy between 2006 and 2011. The lateral view of videofluoroscopy was utilised in the study. A retrospective analysis of the lateral view of videofluoroscopy of these 117 patients was performed to analyse the resting VP gap and its relationship to VP closure.Statistical analysis used
None.Results
Of the 117 cases, 35 had a resting gap of less than 6 mm, 34 had a resting gap between 6 and 10 mm and 48 patients had a resting gap of more than 10 mm.Conclusions
The conclusive finding was that almost all the patients with a resting gap of <6 mm (group C) achieved radiological closure of the velopharynx with speech; thus, they had the least chance of VP insufficiency (VPI). Those patients with a resting gap of >10 mm (group A) did not achieve VP closure on phonation, thus having full-blown VPI. Therefore, it can be concluded that the ideal resting VP gap is approximately 6 mm so as to get the maximal chance of VP closure and thus prevent VPI.

Project description:ObjectiveTo evaluate the association of 2-stage cleft palate (CP) surgery on velopharyngeal insufficiency (VPI) incidence, speech surgeries, and cleft-related surgical burden.DesignRetrospective cohort with follow-up of 4 to 19 years.SettingAcademic, tertiary children's hospital.PatientsPatients who underwent CP surgery between 2000 and 2017. Exclusions included submucous CP or age at last contact under 3.9.InterventionsCleft palate surgery, completed in either a single-stage or 2-stage repair.Main outcome measure(s)Rates of VPI diagnosis and speech surgery and total cleft surgeries; t tests, tests of proportion, and linear and logistic regression were performed. Total cleft-related surgeries were examined in a subset (n = 418) of patients with chart reviews.ResultsA total of 1047 patients were included; 59.6% had 2-stage CP repair, 40.4% had single-stage repair. Approximately 32% of children with 2-stage CP repair were diagnosed with VPI, as opposed to 22% of single-stage patients (P < .001). Children with 2-stage CP repair were 1.8 times as likely to be diagnosed with VPI (P < .001). Speech surgery rates were similar across groups. Patients who had 2-stage repair received an average of 2.3 more cleft-related procedures, when excluding prosthesis management procedures.ConclusionOur data show an increased risk of VPI diagnosis and increased surgical burden among patients receiving 2-stage CP repair.

Project description:The identification of genetic risk factors for non-syndromic oral clefts is of great importance for better understanding the biological processes related to this heterogeneous and complex group of diseases. Herein we applied whole-exome sequencing to identify potential variants related to non-syndromic cleft palate only (NSCPO) in the multiethnic Brazilian population. Thirty NSCPO samples and 30 sex- and genetic ancestry-matched healthy controls were pooled (3 pools with 10 samples for each group) and subjected to whole-exome sequencing. After filtering, the functional affects, individually and through interactions, of the selected variants and genes were assessed by bioinformatic analyses. As a group, 399 variants in 216 genes related to palatogenesis/cleft palate, corresponding to 6.43%, were exclusively identified in the NSCPO pools. Among those genes are 99 associated with syndromes displaying cleft palate in their clinical spectrum and 92 previously related to cleft lip palate. The most significantly biological processes and pathways overrepresented in the NSCPO-identified genes were associated with the folic acid metabolism, highlighting the interaction between LDL receptor-related protein 6 (LRP6) and 5-methyltetrahydrofolate-homocysteine methyltransferase (MTR) that interconnect two large networks. This study yields novel data on characterization of specific variants and complex processes and pathways related to NSCPO, including many variants in genes of the folate/homocysteine pathway, and confirms that variants in genes related to syndromic cleft palate and cleft lip-palate may cause NSCPO.

Project description:BackgroundCleft palate is the commonest multifactorial epigenetic disorder with a prevalence of 0.43-2.45 per 1000. The objectives of this study were to evaluate the clinical features and identify the 22q11.2 deletion in patients with cleft palate in Sri Lanka.Materials and methodsCleft patients attending a Teaching Hospital in Sri Lanka were recruited for this study. The relevant data were obtained from review of case notes, interviews, and examination of patients according to a standard evaluation sheet. Quantitative multiplex polymerase chain reaction (PCR) was performed to identify the 22q11.2 deletion. A gel documentation system (Bio-Doc) was used to quantify the PCR product following electrophoresis on 0.8% agarose gel.Results and conclusionThere were 162 cleft palate patients of whom 59% were females. A total of 92 cleft palate subjects (56.2%) had other associated clinical features. Dysmorphic features (25.27%) and developmental delays (25.27%) were the commonest medical problems encountered. The cleft was limited to the soft palate in 125 patients, while in 25 patients it involved both the hard and the soft palate. There were seven subjects with bifid uvula and five subjects with submucous cleft palate. None of the patients had 22q11.2 deletion in this study population. A multicentered large population-based study is needed to confirm the results of this study and to develop guidelines on the appropriate use of 22q11.2 deletion testing, which are valid for cleft palate patients in Sri Lanka.

Project description:Nonsyndromic orofacial clefts are a common complex birth defect caused by genetic and environmental factors and/or their interactions. A previous genome-wide linkage scan discovered a novel locus for cleft lip with or without cleft palate (CL/P) at 9q22-q33. To identify the etiologic gene, we undertook an iterative and complementary fine mapping strategy using family-based CL/P samples from Colombia, USA and the Philippines. Candidate genes within 9q22-q33 were sequenced, revealing 32 new variants. Concurrently, 397 SNPs spanning the 9q22-q33 2-LOD-unit interval were tested for association. Significant SNP and haplotype association signals (P = 1.45E - 08) narrowed the interval to a 200 kb region containing: FOXE1, C9ORF156 and HEMGN. Association results were replicated in CL/P families of European descent and when all populations were combined the two most associated SNPs, rs3758249 (P = 5.01E - 13) and rs4460498 (P = 6.51E - 12), were located inside a 70 kb high linkage disequilibrium block containing FOXE1. Association signals for Caucasians and Asians clustered 5' and 3' of FOXE1, respectively. Isolated cleft palate (CP) was also associated, indicating that FOXE1 plays a role in two phenotypes thought to be genetically distinct. Foxe1 expression was found in the epithelium undergoing fusion between the medial nasal and maxillary processes. Mutation screens of FOXE1 identified two family-specific missense mutations at highly conserved amino acids. These data indicate that FOXE1 is a major gene for CL/P and provides new insights for improved counseling and genetic interaction studies.

Project description:Orofacial clefts are common birth defects and can occur as isolated, nonsyndromic events or as part of Mendelian syndromes. There is substantial phenotypic diversity in individuals with these birth defects and their family members: from subclinical phenotypes to associated syndromic features that is mirrored by the many genes that contribute to the etiology of these disorders. Identification of these genes and loci has been the result of decades of research using multiple genetic approaches. Significant progress has been made recently due to advances in sequencing and genotyping technologies, primarily through the use of whole exome sequencing and genome-wide association studies. Future progress will hinge on identifying functional variants, investigation of pathway and other interactions, and inclusion of phenotypic and ethnic diversity in studies.

Project description:Plasma microRNAs (miRNAs) have recently emerged as a new class of regulatory molecules that influence many biological functions. However, the expression profile of plasma microRNAs in nonsyndromic cleft palate (NSCP) or nonsyndromic cleft lip with cleft palate (NSCLP) remains poorly investigated. In this study, we used Agilent human miRNA microarray chips to monitor miRNA levels in three NSCP plasma samples (mixed as the CP group), three NSCLP plasma samples (mixed as the CLP group) and three normal plasma samples (mixed as the Control group). Six selected plasma miRNAs were validated in samples from an additional 16 CP, 33 CLP and 8 healthy children using qRT-PCR. Using Venn diagrams, distinct and overlapping dysregulated miRNAs were identified. Their respective target genes were further assessed using gene ontology and pathway analysis. The results show that distinct or overlapping biological processes and signalling pathways were involved in CP and CLP. Our study showed that the common key gene targets reflected functional relationships to the Notch, Wnt, phosphatidylinositol and Hedgehog signalling pathways. Further studies should examine the mechanism of the potential target genes, which may provide new avenues for future clinical prevention and therapy.

Project description:Whether treatment of cleft palate (CP) associated with Robin sequence (RS) should attain outcomes similar to those of isolated cleft palate (ICP) remains unknown. This study compares treatment and outcomes in both conditions and delineates predictors of long-term outcome.MethodsThis retrospective case series of consecutive syndromic and isolated RS- and ICP-patients (1990-2016) includes indications and outcomes of straight-line repair with intravelar veloplasty (SLIV) or Furlow repair depending on cleft and airway characteristics.ResultsSeventy-five RS and 83 ICP patients underwent CP repair. Velopharyngeal insufficiency (VPI) occurred in 41% of RS versus 17% of ICP patients (P = 0.012), and in 60% of patients with syndromic RS versus 16% with isolated RS (P = 0.005). In multivariable logistic regression analysis, wider and more severe CP anatomy was the only factor independently associated with VPI (P = 0.028), in contrast to age at repair, syndromic RS compared with isolated RS, and isolated RS compared with ICP and initial tongue-lip adhesion. Secondary Furlow after primary SLIV was used to treat VPI in all groups, and more frequently in syndromic versus isolated RS patients (P = 0.025).ConclusionsVariability of RS anatomy and airway compromise necessitates individualized treatment protocols. Despite differing CP etiology and other variables, our findings demonstrate cleft anatomy as the only independent variable predictive of VPI comparing RS and ICP patients. Patients with isolated RS should ultimately attain similar VPI outcomes compared with ICP patients. Obstructive speech operations in RS patients can be avoided without compromising speech outcome by reserving the prsocedure for secondary cases.

Project description:OBJECTIVE: To address the effect of intrinsic factors on craniofacial growth by analyzing the craniofacial morphology of unoperated isolated cleft palate in Chinese adult. MATERIALS AND METHODS: This study included 37 nonsyndromic isolated cleft palate and 39 age and gender matched non-clefts. Twenty-six cephalometric measurements were employed to evaluate the facial morphology. Independent samples T test and Mann-Whitney U were used for comparison. Significant difference was defined at 95% level. RESULTS: Data from this study showed patients with unoperated isolated cleft palate have a reduced maxillary sagittal length (ANS-PMP, A-PMP, P<0.05), a smaller ANB angle (ANB, P<0.05) and a retrusive ANS point (S-N-ANS, P<0.05; Ba-N-ANS, P<0.05). Measurements descripted position of maxilla (S-Ptm, P>0.05), depth of bony pharynx (Ba-PMP, P>0.05), anterior and posterior maxillary height (N-ANS, P>0.05; R-PMP, P>0.05) and mandible morphology (including linear measurements and angle measurements) did not show any significant difference between case and control groups. CONCLUSIONS: Patients with isolated cleft palate were characterized by maxillary retrusion. Mandible morphology and cranial basal morphology in isolated cleft palate showed no significant difference with nonclefts. Patients with isolated cleft palate are more vulnerable to cross bite than nonclefts. Intrinsic deficiencies did detrimental effect on maxilla sagittal length, but did no detrimental effect on maxilla position, mandible size and position.

Project description:The decision for lip revision surgery in patients with repaired cleft lip/palate is based on surgeons' subjective evaluation of lip disability. An objective evaluation would be highly beneficial for the assessment of surgical outcomes. In this study, the effects of lip revision on circumoral movements were objectively quantified. The hypothesis was that lip revision increases scarring and impairment. The study was a non-randomized clinical trial that included patients with cleft lip who had revision, patients with cleft lip who did not, and non-cleft control individuals. Three-dimensional facial movements were measured. Revision patients were measured before and after surgery. Other individuals were measured at similar intervals. Regression models were fit to summary measurements, and changes were modeled. Patients with repaired cleft lip/palate had fewer mean movements than control individuals. Lip revision did not worsen mean movements; however, individual patients' movements varied from 'improvement' to 'no change' to 'worse' relative to those of control individuals.
