Detection and classification of unilateral cleft alveolus with and without cleft palate on panoramic radiographs using a deep learning system.

Although panoramic radiography has a role in the examination of patients with cleft alveolus (CA), its appearances is sometimes difficult to interpret. The aims of this study were to develop a computer-aided diagnosis system for diagnosing the CA status on panoramic radiographs using a deep learning object detection technique with and without normal data in the learning process, to verify its performance in comparison to human observers, and to clarify some characteristic appearances probably related to the performance. The panoramic radiographs of 383 CA patients with cleft palate (CA with CP) or without cleft palate (CA only) and 210 patients without CA (normal) were used to create two models on the DetectNet. The models 1 and 2 were developed based on the data without and with normal subjects, respectively, to detect the CAs and classify them into with or without CP. The model 2 reduced the false positive rate (1/30) compared to the model 1 (12/30). The overall accuracy of Model 2 was higher than Model 1 and human observers. The model created in this study appeared to have the potential to detect and classify CAs on panoramic radiographs, and might be useful to assist the human observers.

Prevalence of Tympanostomy Tube Placement in Relation to Cleft Width and Type.

OBJECTIVES/HYPOTHESIS: The prevalence of tympanostomy tube surgery (TTS) in patients with a cleft deformity was investigated, in relation to cleft width and cleft type. STUDY DESIGN: Retrospective review of medical health records. METHODS: Retrospective review of medical health records. Seventy-eight patients with non-syndromic cleft deformity of the palate and/or alveolus and lip between 2003 and 2017 were investigated. All available medical documents were analyzed. The study group was divided into subgroups: 1) patients with isolated cleft palate (CP) and patients with a cleft palate with cleft lip and alveolus (CLP). 2) According to Veau's classification (I-IV), further subgroups were defined. Cleft width was measured using plaster cast models. RESULTS: TTS was performed in 55% of the patients (n = 43). Considering Veau's classification, TTS was conducted as follows: Veau I 65.2% (n = 15/23), Veau II 55.0% (n = 11/20), Veau III 47.6% (n = 10/21), and Veau IV 50.0% (n = 7/14). Cleft classifications, maxillary arch width, and absolute/relative cleft width had no statistical impact on TTS occurrence. Although no significant correlation could be found, patients in our study group with CP (Veau I and II) underwent TTS more often (60.5%, n = 26/43) than patients with CPL (Veau III and IV; 48.6%, n = 17/35) during a three-year follow-up. CONCLUSION: None of the cleft characteristics examined had a significant impact on the proportion of patients who received TTS. Nevertheless, patients with lower Veau classification and CP received tympanostomy tubes more often. Therefore, otolaryngologists and pediatricians treating children with cleft palate should maintain a high level of suspicion for chronic middle ear effusion, even in patients with small clefts. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:E2764-E2769, 2021.

Post-operative intravenous fluid administration for infant cleft surgery: An observational study.

OBJECTIVE: To investigate post-operative intravenous fluid administration and length of stay in a single site cleft centre. Previous publications have linked increased length of stay following primary cleft surgery to the administration of intravenous fluids post-operatively. MATERIALS AND METHODS: One hundred and ten primary cleft operations were conducted from May 2015 to April 2016 on non-syndromic infants. At West Midlands Cleft Centre, there are three cleft surgeons and 20 paediatric anaesthetists. This observational study compares classification of cleft type and surgical procedure with intravenous fluid administration, time taken to tolerate oral feeding, and length of stay. RESULTS: Cleft lip repair infants had the shortest length of stay in hospital, 25 h 8 min (median) and 33% had intravenous fluids. The palate repair only and lip and palate repair children had a median length of stay of 29 h 20 min and 29 h 0 min respectively, A total of 79% and 76% of these groups had intravenous fluids administered. Cleft lip repair infants fed in significantly less time than palate alone or lip and palate operations (p values 0.00 and 0.03, respectively). CONCLUSION: Cleft lip repair only infants feed well post-operatively and rarely require intravenous fluids. Infants having cleft repair involving the palate are slower to feed orally, and may require fluids due to poor oral intake. Intravenous fluids following lip repair is associated with longer hospital stay. We suggest intravenous fluids may not be needed routinely following cleft lip repair, but should always be considered following repair involving the palate.

Prenatal ultrasound diagnosis of cleft palate without cleft lip, the new ultrasound semiology.

OBJECTIVES: The aim of this study was to define the prenatal ultrasound semiology of cleft palate without cleft lip using 3D visualization of the fetal palate. METHODS: A prospective longitudinal study was performed in our University Hospital Center from 2011 to 2018. The fetal secondary palate was studied in 3D, starting with 2D axial transverse ultrasound view. We defined a cleft palate as a disruption of the horizontal plate of the palatine bone of the secondary palate. Prenatal findings were correlated to anatomic postnatal examinations performed by a paediatric plastic surgeon. RESULTS: Forty-three cases of cleft palate without cleft lip were prenatally diagnosed, of whom 34 were associated with malformations. We defined four types of disruptive appearances: isolated nonvisualization of the posterior nasal spine; partial-disruption or cleft velum; complete disappearance or V-shaped cleft palate; and complete disappearance or U-shaped cleft palate. The adjusted kappa coefficient, between prenatal and postnatal evaluation, was 0.88 (95% CI: 0.79-0.97), corresponding to an excellent agreement. CONCLUSIONS: Using a strictly axial transverse ultrasound view, visualization of the secondary fetal palate enables to diagnose a cleft palate without cleft lip. This method offers a prenatal anatomic classification of cleft palate with a high level of concordance to postnatal findings.

Holistic Communication Assessment for Young Children With Cleft Palate Using the International Classification of Functioning, Disability and Health:Children and Youth.

Purpose Children with a cleft palate (± cleft lip; CP±L) can have difficulties communicating and participating in daily life, yet speech-language pathologists typically focus on speech production during routine assessments. The International Classification of Functioning, Disability and Health: Children and Youth Version (ICF-CY; World Health Organization, 2007) provides a framework for holistic assessment. This tutorial describes holistic assessment of children with CP±L illustrated by data collected from a nonclinical sample of seven 2- to 3-year-old children, 13 parents, and 12 significant others (e.g., educators and grandparents). Method Data were collected during visits to participants' homes and early childhood education and care centers. Assessment tools applicable to domains of the ICF-CY were used to collect and analyze data. Child participants' Body Functions including speech, language, and cognitive development were assessed using screening and standardized assessments. Participants' Body Structures were assessed via oral motor examination, case history questionnaires, and observation. Participants' Activities and Participation as well as Environmental and Personal Factors were examined through case history questionnaires, interviews with significant others, parent report measures, and observations. Results Valuable insights can be gained from undertaking holistic speech-language pathology assessments with children with CP±L. Using multiple tools allowed for triangulation of data and privileging different viewpoints, to better understand the children and their contexts. Several children demonstrated speech error patterns outside of what are considered cleft speech characteristics, which underscores the importance of a broader assessment. Conclusion Speech-language pathologists can consider incorporating evaluation of all components and contextual factors of the ICF-CY when assessing and working with young children with CP±L to inform intervention and management practices.

Correlation between Type of Clefting and the Incidence of Otitis Media among Children with Lip and/or Palate Clefts.

INTRODUCTION: Otitis media is a frequent condition among children with high morbidity. Orofacial clefts are undoubtedly one of the most well-established risk factors for otitis media during childhood. The clinical spectrum of disease in orofacial clefting is broad according to the subtype of malformation. This study aims to correlate the occurrence of otitis media among lip and/or palate cleft children with clinical and epidemiological parameters, in particular with the subtypes of malformation diagnosed. METHODS: This is a clinical, retrospective, case-control type of study. Epidemiological and clinical data were obtained from medical records of children born between 2005 and 2008 and attending a multidisciplinary center for cleft patients. RESULTS: 53% of the patients had registers of middle ear disorder during follow-up, and secretory otitis media was the most frequently diagnosed condition. Five children (1.39%) had chronic otitis media during the study period. Those patients with malformations including involvement of structures located posteriorly to the incisive foramen were more frequently diagnosed with otitis media than those with isolated pre-foramen cleft (p value < 0.001, odds ratio: 5.33). Gender and bilateral malformations did not correlate with increased occurrence of middle ear disease (p value > 0.05). CONCLUSION: Otitis media is frequent among lip and/or palate cleft children, although the grade of middle ear involvement seems to vary widely within this population. Post-foraminal malformations are clearly associated with increased incidence of otitis media, as well as with more severe diseases.

[Application of mathematical function model in morphological description and classification of bone defect in cleft palate cases].

Objective: To establish the functional models based on various shapes of bone defects in isolated cleft palate patients and to classify the bone defects of the cleft palate cases using different functional curves. Methods: Tracking back from January 2018 to December 2018, 143 patients with cleft palate (Veau Ⅰ & Ⅱ) treated in Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology, were included (age of 7 months to 25 years, average age 1.6 years, median age 1.0 year, the male to female ratio was 0.57∶1).The pre-operative (CT) data sets were reconstructed into a three dimensional model to produce a direct image of the cleft palate. According to the shapes of the bone defect, cleft palate cases were divided into three types, i.e."" shape, inverted "V" shape and inverted "U" shape, and then the cases were assessed and reviewed by five examiners independently. Using Microsoft Excel software, the curves of the bone defect were placed in the coordinate system for mathematical modeling, including exponential function (y=ae(bx)), linear function (y=ax+b) and logarithm function (y=alnx+b). The function of the maximum fit R(2) value was used as the final fit curve. Statistical analysis was performed in four aspects: ① The reliability and feasibility of the curve fitting of the functions; ② The calculation of the composition ratio of the types of bone defect; ③Analyzing the correspondence between the subjective judgment results and fitting function curves; ④ The R(2) values of three types of functional curves homologous to different morphological types, and the data were tested by variance analysis and P values were shown. Results: Among the 143 patients with cleft palate, the "" shaped defect accounted for 18% (26/143), the inverted "V" shaped defect accounted for 31% (44/143), and the inverted "U" shaped defect accounted for 51% (73/143). The coincidence rate of the "" shaped defect with the exponential function (y=ae(bx)) was 96%, the coincidence rate of the inverted "V" shaped defect with the linear function (y=ax+b) was 82%, and the coincidence rate of the inverted "U" shaped defect with the logarithmic function (y=alnx+b) was 93%. The differences in R(2) values amongst the three groups were statistically significant (P<0.05). Conclusions: The shapes of bone defects of the incomplete cleft palate can be described by functional curve models which include exponential, linear and logarithmic functions and can be used to classify and lay the foundation for digital classification of cleft lip and palate cases.

A systematic genetic analysis and visualization of phenotypic heterogeneity among orofacial cleft GWAS signals.

Phenotypic heterogeneity is a hallmark of complex traits, and genetic studies of such traits may focus on them as a single diagnostic entity or by analyzing specific components. For example, in orofacial clefting (OFC), three subtypes-cleft lip (CL), cleft lip and palate (CLP), and cleft palate (CP) have been studied separately and in combination. To further dissect the genetic architecture of OFCs and how a given associated locus may be contributing to distinct subtypes of a trait we developed a framework for quantifying and interpreting evidence of subtype-specific or shared genetic effects in complex traits. We applied this technique to create a "cleft map" of the association of 30 genetic loci with three OFC subtypes. In addition to new associations, we found loci with subtype-specific effects (e.g., GRHL3 [CP], WNT5A [CLP]), as well as loci associated with two or all three subtypes. We cross-referenced these results with mouse craniofacial gene expression datasets, which identified additional promising candidate genes. However, we found no strong correlation between OFC subtypes and expression patterns. In aggregate, the cleft map revealed that neither subtype-specific nor shared genetic effects operate in isolation in OFC architecture. Our approach can be easily applied to any complex trait with distinct phenotypic subgroups.

The prenatal diagnosis and classification of cleft palate: the role and value of magnetic resonance imaging.

OBJECTIVE: The aim of this study was to evaluate the value of MRI in the prenatal diagnosis and classification of cleft palate (CP). METHODS: We collected 94 fetal cases that were suspected of cleft palate with or without cleft lip by prenatal ultrasound (US) and then carried out further MRI to examine the entire body of each fetus within 1 week. The diagnoses resulting from MRI and US examination were compared separately with the final diagnoses obtained from postnatal physical examination or fetal autopsy. The diagnostic accuracy between MRI and US was then determined. RESULTS: During the follow-up period, the results for 6 fetuses (6.38%) were lost. Of the remaining 88 cases, the final diagnoses identified 23 cases of cleft lip (CL), 45 cases of unilateral cleft lip with cleft palate (UCLP), 4 cases of median cleft lip with cleft palate (MCLP), 12 cases of bilateral cleft lip with cleft palate (BCLP), 3 cases of unilateral cleft lip and cleft alveolus (CLA), and 1 case of isolated cleft palate (CPO). The total accuracy rate of US was 59.09%, while that of MRI was 92.05%. More importantly, 81 cases were accurately identified by MRI; the accuracy rate for CL, UCLP, MCLP, BCLP, CLA, and CPO was 86.96%, 95.56%, 100%, 91.67%, 66.67%, and 100%, respectively. CONCLUSION: Our results suggest that MRI could be a useful adjunct to US examination in the prenatal diagnosis of fetuses with cleft palate, and further demonstrates the classification and degree of involvement of the cleft palate. KEY POINTS: • MRI is a useful adjunct to prenatal ultrasound. • MRI has a higher accuracy rate for CP. • The accurate classification of CP diagnosed by MRI can guide clinical management.

Pakistan Comprehensive Fistula Classification: A Novel Scheme and Algorithm for Management of Palatal Fistula/Dehiscence.

BACKGROUND: It is not easy to find a management-based classification of palatal fistula in the literature. A few attempts have been made to classify the wide variety of fistulae that do not describe the fistula details comprehensively and guide toward its management. The authors have come across a wide variety of fistulae that could not be classified according to any of the prevailing classification systems. The presented classification gives a clear and exact understanding of location and size of fistula/dehiscence. Palatal function has been included as one of the important determinants for devising a management plan. Based on this classification, the authors have proposed an algorithm that encompasses clear guidelines for surgical treatment of these fistulae. METHODS: Over the past 15 years, the authors' team operated on 2537 palatal fistula patients. The medical records of these patients were reviewed to determine the location, size, and velopharyngeal competence. A new classification and algorithm were developed. RESULTS: Of 2537 patients, 2258 had midline fistulae, 208 had lateral fistulae, and 53 had subtotal fistulae. There were 18 patients with dehiscence. Recurrence developed in 181 patients. CONCLUSION: The authors believe that this classification and algorithm can help follow a practical approach to manage palatal fistulae and dehiscence.

Craniofacial cephalometric morphologies in different cleft types: a retrospective cross-sectional study of 212 patients.

OBJECTIVE: The aim of this study was to evaluate and compare the craniofacial cephalometric morphologies among different cleft types in a Spanish population. METHODS: A retrospective cross-sectional study was carried out on 212 patients. The patients were subdivided into four groups according to their cleft types: unilateral cleft lip and palate; bilateral cleft lip and palate; cleft lip; and cleft palate. Angular and linear cephalometric measurements were taken on lateral radiographs. RESULTS: Unilateral cleft lip and palate was associated with a dolichofacial growth pattern, skeletal Class III with correct maxillary position, and lingual incisor inclination. Bilateral cleft lip and palate was associated with a mesofacial growth pattern, skeletal Class I with protruded maxillary position, and lingual incisor inclination. Cleft palate was associated with a mesofacial growth pattern, skeletal Class III with correct maxillary position, and lingual incisor inclination. Cleft lip was associated with a brachyfacial growth pattern, skeletal Class I with protruded maxillary position, lingual upper incisor inclination, and corrects lower incisor inclination. Significant correlations were observed between cleft types and their craniofacial cephalometric measurements. CONCLUSIONS: The present information can be used for the determination of orthodontic treatment and even future orthognathic surgery planning, a requirement in most cleft patients.

Increased Risk for Neurodevelopmental Disorders in Children With Orofacial Clefts.

OBJECTIVE: Children with orofacial clefts (OFC) may have an increased risk of poor mental health. This study aimed to investigate the risk of psychiatric diagnoses in individuals with OFC, stratified by cleft type. METHOD: A nationwide register-based cohort of all individuals born with nonsyndromic OFC in Sweden between 1973 and 2012 (n = 7,842) was compared to a matched cohort (n = 78,409) as well as to their unaffected siblings (n = 9,637). The risk of psychiatric diagnoses, suicide attempts, and suicides was examined by crude and adjusted Cox regression models. Effect modification by sex was investigated with interaction terms in the models. RESULTS: Children with cleft lip (CL) had a significantly higher risk of any psychiatric disorder, intellectual disability, and language disorders; children with cleft lip and palate (CLP) had, in addition, an increased risk of autism spectrum disorder (ASD). Children with cleft palate only (CPO) had risk increases for the same diagnoses as children with CL and CLP, but with higher hazard ratios, and also for psychotic disorders, attention-deficit/hyperactivity disorder (ADHD), and other behavioral or emotional disorders in childhood. Sex stratification indicated higher risk increases among females in CL and CLP but not in CPO. Siblings without OFC were less likely to be diagnosed with any psychiatric disorder, intellectual disability, language disorder, ASD, or ADHD compared to their siblings with OFC. CONCLUSION: Children with nonsyndromic clefts had a significantly higher risk of neurodevelopmental disorders. This risk is unlikely to be explained by familial influences such as inherited genetic or shared environmental factors.

SPINA classification of cleft lip and palate: A suggestion for a complement.

Spina's classification uses the incisive foramen as an anatomic reference to define groups I, II, and III. In some cases, the morphological manifestation of the cleft arises simultaneously pre- and postforamen, but without communicating. Considering that group I refers to isolated clefts of the primary palate and group III includes isolated clefts of the secondary palate, the authors suggest the classification group IIa for the association of these two occurrences in the same patient, thus associating two classifications. The original structure proposed by Spina is maintained and simply complemented and updated to Spina-A classification.

Integrated assessment of differentially expressed plasma microRNAs in subtypes of nonsyndromic orofacial clefts.

BACKGROUND: Orofacial clefts include cleft lip only (CLO), cleft palate only (CPO), and cleft lip with palate (CLP). Previously, we reported the expression profile of plasma microRNAs in CLO, CPO, and CLP, respectively. However, the interaction of each subtype remains poorly investigated. METHODS: In this study, we integrated the expression profiles of plasma miRNAs in these 3 subtypes, and assessed the distinct and overlapping dysregulated miRNAs using Venn diagrams. Their respective target genes reported in the literature were further analyzed using pathway analysis. RESULTS AND CONCLUSION: The results showed that distinct or overlapping signaling pathways were involved in CLO, CPO, and CLP. The common key gene targets reflected functional relationships to the Wnt, Notch, TGF-beta, and Hedgehog signaling pathways. Further studies should examine the mechanism of the potential target genes, which may provide new avenues for future clinical prevention and therapy.

Subphenotyping and Classification of Cleft Lip and Alveolus in Adult Unoperated Patients: A New Embryological Approach.

OBJECTIVE: Previously, a new embryological classification was introduced subdividing oral clefts into fusion and/or differentiation defects. This subdivision was used to classify all subphenotypes of cleft lip with or without alveolus (CL±A). Subsequently, it was investigated whether further morphological grading of incomplete CLs is clinically relevant, and which alveolar part is deficient in fusion/differentiation defects. DESIGN: Observational cohort study. SETTING: Three hundred fifty adult unoperated Indonesian cleft patients presented themselves for operation. Cephalograms, dental casts, and intraoral and extraoral photographs-eligible for the present study-were used to determine morphological severity of CL±A. PATIENTS: Patients with unilateral or bilateral clefts of the primary palate only were included. MAIN OUTCOME MEASURES: Clefts were classified-according to developmental mechanisms and timing in embryogenesis-as fusion and/or differentiation defects. Grades of incomplete CLs were related to the severity of alveolar clefts (CAs) and hypoplasia, and permanent dentition was used to investigate which alveolar part is deficient in fusion/differentiation defects. RESULTS: One hundred eight adult patients were included. All subphenotypes-96 unilateral and 12 bilateral clefts-could be classified into differentiation (79%), fusion (17%), fusion-differentiation (2%), or fusion and differentiation (2%) defects. The various grades of incomplete CLs were related to associated CAs and hypoplasia, and all alveolar deformities were located in the premaxillae. CONCLUSIONS: This study showed that all CL±A including the Simonart bands can be classified, that further morphological grading of incomplete CLs is clinically relevant, and that the premaxilla forms the deficient part in alveolar deformities.

Dentoskeletal effects of facemask therapy in skeletal Class III cleft patients with or without bone graft.

INTRODUCTION: The association between maxillary protraction and bone graft in patients with cleft lip and palate remains unclear. The purpose of this study was to investigate whether a secondary alveolar bone graft influences dentoskeletal effects of facemask therapy in unilateral cleft lip and palate patients with a skeletal Class III relationship. METHODS: In this prospective nonrandomized clinical trial, 61 consecutive boys with unilateral cleft lip and palate and skeletal Class III malocclusion were divided into 3 groups: grafted facemask group (n = 21), ungrafted facemask group (n = 20), and untreated control group (n = 20). Sixteen dentoskeletal measurements on lateral cephalometric radiographs were compared before and after therapy or observation with 1-way analysis of variance or the Mann-Whitney U test. RESULTS: After facemask therapy, the grafted group showed a statistically significantly greater advancement of Point A (S-Vert-A, 4.18 ± 1.94 mm; SNA, 3.51° ± 2.21°) than did the ungrafted group (S-Vert-A, 2.64 ± 1.58 mm; SNA, 1.92° ± 1.05°). Furthermore, significant SNB changes were found in the grafted group when compared with those in the ungrafted group (-0.38° ± 1.77° vs -1.69° ± 1.34°; P <0.05). The changes in the mandibular plane angle (MP-SN, MP-FH) in the grafted group were less pronounced than in the ungrafted group by approximately 2° (P <0.05). Flaring of the maxillary incisors was more pronounced in treated subjects than in untreated subjects. The mandibular incisors proclined in both grafted (1.54° ± 4.21°) and control (0.97° ± 3.71°) patients, and were retroclined in the ungrafted group (-2.13° ± 3.68°). CONCLUSIONS: Facemask therapy performed after an alveolar bone graft produced more anterior maxillary migration (90%) and less pronounced mandibular clockwise rotation (10%) than those in the ungrafted group (50%, 50%, respectively).

Cleft Skeletal Asymmetry: Asymmetry Index, Classification and Application.

OBJECTIVE: To quantitatively measure the extent of 3D asymmetry of the facial skeleton in patients with unilateral cleft lip and palate (UCLP) using an asymmetry index (AI) approach, and to illustrate the applicability of the index in guiding and measuring treatment outcome. METHOD: Two groups of subjects between the ages of 15 and 20 who had archived CBCT scan were included in this study. Twenty-five patients with complete UCLP were compared with 50 age-matched noncleft subjects. The CBCT scans were segmented and landmarked for 3D anthropometric analysis. An AI was calculated as a quantitative measure of the extent of facial skeletal asymmetry. RESULTS: For the control group, the AI ranged from 0.72 ± 0.47 at A point to 4.77 ± 1.59 at Gonion. The degree of asymmetry increased with the increasing laterality of the landmark from the midsagittal plane. In the UCLP group, the values of AI significantly increased compared to the control group at nearly all measured landmarks. The extent of the asymmetry to involve the upper, middle, and lower facial skeleton varied widely with the individual patient with UCLP. CONCLUSION: The asymmetry index is capable of capturing the 3D facial asymmetry of subjects with UCLP and as a basis for classification of the extent of the asymmetry. We found the index to be applicable in surgical planning and in measuring the outcome in improving the symmetry in patients who have undergone orthognathic surgery.

Speech and Surgical Outcomes in Children With Veau Types III and IV Cleft Palate: A Comparison of Internationally Adopted and Nonadopted Children.

OBJECTIVE: This study compares speech and surgical outcomes in internationally adopted and nonadopted patients undergoing cleft palate repair, and examines the influence of age at initial palatoplasty. DESIGN: Retrospective cohort study setting: Tertiary Care Children's Hospital. PATIENTS: 70 international adoptees and 211 nonadoptees with Veau type III and IV clefts (without associated syndrome) repaired at our institution. OUTCOME MEASURES: Outcomes included VPI, compensatory misarticulations, intelligibility, nasal air emission, oronasal fistula, and secondary speech surgery. Speech evaluations completed near 5 years of age were gathered from a prospectively collected database. RESULTS: Adoptees underwent palatoplasty 5.2 months after arrival, a mean of 10.4 months later than nonadoptees. Adoptees were significantly more likely to develop moderate/severe VPI and trended toward more frequent need for secondary speech surgery. Oronasal fistula occurred at similar rates. Increased age at initial palatoplasty was a significant predictor of moderate to severe VPI, and need for secondary speech surgery. CONCLUSIONS: International adoptees undergo palatoplasty 10.4 months later than nonadoptees and are significantly more likely to develop moderate/severe VPI, with a trend toward increased secondary speech surgery. An association between treatment delay and moderate/severe VPI and secondary speech surgery has been demonstrated. While a causal relationship between delayed repair and inferior outcomes in international adoptees has not been proven, this data suggests that surgical intervention upon unrepaired cleft palates soon after adoption may be beneficial. The opportunity for a change in practice exists, as half of the 10.4-month relative delay in palate repair occurs postadoption.

Universal Applicability of the Furlow Palatoplasty: Resident as Primary Surgeon in a Consecutive, Nonselective Series.

BACKGROUND: Questions persist regarding the general applicability of the Furlow palatoplasty technique, and thus, widespread adoption of its use has been uneven. This study describes a consecutive, nonselective series of primary Furlow palatoplasties. Highlighted is the unique fact that plastic surgical residents functioned as the primary surgeon for all steps of all procedures throughout the series. METHODS: A retrospective review was undertaken of all primary palatoplasties performed under the direction of the senior surgeon between December 2005 and April 2012. A stringent requirement for speech outcome reporting was patient age at the latest assessment of older than 4.5 years. Other measured parameters included fistula rate, incidence of secondary surgery, and procedure duration. RESULTS: Seventy-five patients were included in this study. Nasal resonance was rated as "normal" in 56.1% of the patients and "mildly hypernasal or better" in 95.1% of the patients. Articulation errors were detected in 14.6% of the patients, and symptoms related to nasal air emission were detected in 4.9% of the patients. Overall fistula rate was 5.3%. The following associations were detected: (1) Veau cleft type and procedure duration, P = 0.001; (2) resident year of training and procedure duration, P = 0.009; (3) developmental delay and resonance score, P = 0.002; (4) patient age at surgery and resonance score, P = 0.025; and (5) presence of syndrome and resonance score, P = 0.036. CONCLUSIONS: This nonselective series of consecutive Furlow palatoplasty procedures demonstrates that plastic surgical residents are able to match best published clinical results performing the entire procedure under the close supervision and guidance of an assisting surgical mentor.
