Bone-Anchored Maxillary Protraction for Adolescents with Cleft Palate and Class III Malocclusion: A Case Series.

To describe the long-term treatment course of bone-anchored maxillary protraction (BAMP) and evaluate orthognathic surgical indications after BAMP.Retrospective case series.Craniofacial/Cleft Palate Program at the Orthopaedic Institute for Children in Los Angeles, CA.Twelve male patients with cleft palate (CP), unilateral cleft lip and palate (UCLP), or bilateral cleft lip and palate (BCLP) and Class III malocclusion treated with BAMP (mean age: 11.4 ± 2.6 years) were included.BAMP treatment was performed by placement of bone-anchored maxillary and mandibular plates connected with intraoral Class III dental elastics or maxillary plates connected to a facemask.We retrospectively assessed BAMP treatment variables, including age at surgery, revision surgeries, and treatment duration. The primary goal was correction to class I occlusion.Twelve patients underwent BAMP treatment for an average of 4.4 ± 2.4 years. Two patients were corrected to class I occlusion at the time of this report. Le Fort I advancement was no longer required in two patients (16.7%), it was required for nine patients (75.0%) and was completed for one patient following BAMP treatment (8.3%).This preliminary report demonstrated that BAMP treatment may be associated with a minimal reduction in the requirement for Le Fort I advancement at skeletal maturity. Future studies with larger sample sizes are necessary to confirm this association.

Velopharyngeal Insufficiency in Craniofacial Microsomia: Prevalence, Diagnosis, and Treatment.

ABSTRACT: The purpose of this study was to analyze the prevalence, diagnosis, and management of velopharyngeal insufficiency (VPI) in patients with craniofacial microsomia (CFM).Craniofacial microsomia patients 13 years of age and above treated at 2 centers from 1997 to 2019 were reviewed retrospectively for demographics, prevalence of VPI, and management of VPI. Patients with isolated microtia were excluded. Comparisons were made between patients with and without VPI using chi-square and independent samples t tests.Among 68 patients with CFM (63.2% male, mean 20.7 years of age), VPI was diagnosed in 19 patients (27.9%) at an average age of 7.2 years old. Among the total cohort, 61 patients had isolated CFM, of which 12 (19.6%) were diagnosed with VPI. Of the patients with isolated CFM and VPI, 8 patients (66.7%) were recommended for nasoendoscopy, of which only 2 patients completed. Seven isolated CFM patients (58.3%) underwent speech therapy, whereas none received VPI surgery. In contrast, 7 patients were diagnosed with both CFM and cleft lip and/or palate (CL/P), all of whom had VPI and were recommended for nasoendoscopy, with 5 (71.4%) completing nasoendoscopy, 6 (85.7%) undergoing speech therapy, and 6 (85.7%) undergoing corrective VPI surgery. Overall, we demonstrated that VPI was present in 27.9% of all CFM patients. On subset analysis, VPI was diagnosed in 20% of patients with isolated CFM and 100% of patients with CFM and CL/P. In addition, despite clinical diagnosis of VPI, a sizeable proportion of isolated CFM patients did not undergo therapy or surgical interventions.

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.

Giant cranial osteoma: successful staged excision of the largest reported.

Craniofacial osteomas are benign, slow-growing neoplasms of the craniofacial region that are usually asymptomatic. Uncommonly, giant craniofacial osteomas may be symptomatic and cause serious morbidity including ophthalmologic problems, cerebral compression, pneumocephalus, and seizures. We present a case of a 15-year-old Asian adolescent girl with a giant cranial osteoma (17.5 × 13.2 × 5 cm: significantly larger than previously reported). She also had multiple other synchronous giant osteomas of the face causing facial asymmetry. These osteomas were resected in a multiple-staged approach with a good aesthetic and functional outcome.

Early Alveolar Bone Grafting Is Associated with Lower Regraft Rates and Improvements in Long-Term Psychosocial Outcomes.

BACKGROUND: Late childhood (8 to 10 years of age) has emerged as a vulnerable period in children with cleft and craniofacial anomalies such that increased interventions during this period are associated with worse long-term patient-reported anxiety and depressive symptoms. These findings suggest that one possible practice change may be to consider changes in timing for surgical treatment algorithms. In this work, the authors investigated outcomes in altering the timing of the most common operation in late childhood for cleft lip and palate patients, alveolar bone grafting. METHODS: A two-part, multi-institutional cohort study was conducted. To understand the feasibility of changing alveolar bone graft timing with respect to surgical success, reoperation rates were retrospectively compared among patients grafted at different ages (4 to 7, 8 to 10, and 11 to 13 years of age). To understand the long-term effect of changing alveolar bone graft timing on psychosocial outcomes, the psychosocial suite of the Patient-Reported Outcomes Measurement Information System was prospectively administered to teenagers and adults with cleft lip and palate. RESULTS: Among the three age groups, early grafting (4 to 7 years of age) demonstrated the lowest regraft rates compared with the other groups. As these results suggested that early grafting is a viable alternative to standard timing, we next compared the differences in long-term psychosocial outcomes. Patients who were grafted early reported lower levels of anxiety and depressive symptoms as teenagers and adults. CONCLUSION: Altering timing of one stage in cleft lip and palate reconstruction to an earlier age decreases regraft rates and improves long-term patient-reported anxiety and depressive symptoms.

Long-Term Orthognathic Considerations in the Pierre Robin Sequence Patient.

BACKGROUND: One of the arguments against early intervention for micrognathia in Pierre Robin sequence is the concept that the growth of the mandible will eventually "catch up." Long-term growth of the mandible and occlusal relationships of conservatively managed Pierre Robin sequence patients remain unknown. In this study, the authors evaluated the orthognathic surgery requirements for Pierre Robin sequence patients at skeletal maturity. METHODS: Orthognathic surgical requirements of conservatively managed Pierre Robin sequence and isolated cleft patients (aged ≥13 years) at two institutions were reviewed and analyzed using t test, chi-square test, and Fisher's exact test. Values of p < 0.05 were considered statistically significant. RESULTS: Of the Pierre Robin sequence patients (n = 64; mean age ± SD, 17.9 ± 2.9 years), 65.6 percent were syndromic (primarily Stickler and velocardiofacial syndrome), 96.9 percent had a cleft palate, and 39.1 percent required orthognathic surgery at skeletal maturity. Nonsyndromic and syndromic Pierre Robin sequence patients demonstrated no differences in occlusal relationships or mandibular surgery frequency. The majority of Pierre Robin sequence patients requiring mandibular advancement had a class II occlusion. Comparison of Pierre Robin sequence patients to isolated cleft palate patients (n = 17) revealed a comparable frequency of orthognathic surgery between the two; however, Pierre Robin sequence patients did require mandibular advancement surgery at a greater frequency than cleft palate patients (p = 0.006). CONCLUSIONS: The present study found that 39.1 percent of conservatively managed Pierre Robin sequence patients required orthognathic surgery at skeletal maturity, of which the vast majority required mandibular advancement for class II malocclusion. These data suggest that mandibular micrognathia in conservatively managed Pierre Robin sequence patients may not resolve over time and may require surgical intervention. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Effect of Parental English Proficiency on Psychosocial Functioning in Children with Craniofacial Anomalies.

BACKGROUND: Psychosocial distress in children with craniofacial anomalies is multifactorial. A known cause of childhood psychosocial distress is parental limited English proficiency; however, its role as a psychosocial stressor in the craniofacial anomaly population remains unknown. The current study aimed to understand the potential influence of parental English proficiency in children with craniofacial anomalies. METHODS: Two hundred ninety-six children were prospectively evaluated at the University of California, Los Angels and the Orthopaedic Institute for Children using the Pediatric Patient-Reported Outcomes Measurement Information System to assess anger, anxiety, depression, and peer relationships. Children were grouped by parental English proficiency based on the requirement or lack thereof for interpreting services during clinic appointments. Independent t tests, analyses of variance, and linear regressions were performed to compare groups and identify predictors for psychosocial functioning. RESULTS: Although comparison children did not exhibit any differences in psychosocial scores with respect to parental English proficiency, craniofacial anomaly children with parents who have limited English proficiency demonstrated higher anger, anxiety, depression, and lower peer relationships compared with those with parents who are English proficient. Linear regression analyses demonstrated that limited English proficiency in parents was a significant predictor for anger (p = 0.005), anxiety (p = 0.002), depression (p < 0.001), and poor peer relationships (p < 0.001) in children with craniofacial anomalies. CONCLUSIONS: Parental English proficiency is associated with increased psychosocial distress in children with craniofacial anomalies. Future efforts toward identification of and assistance for parents with limited English proficiency to address barriers to care may improve psychosocial function in children with craniofacial anomalies. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Long-Term Effect of Multiple Operations on Psychosocial Function in Teenage Cleft Lip and Palate Patients.

BACKGROUND: Cleft lip and palate patients undergo a significant number of interventions during their childhood and adolescence. Although the intention of such interventions is to improve psychosocial functioning, there exists a paucity of data on the psychosocial outcomes of the burden of care on cleft children. In this work, the long-term effects of quantity and timing of childhood operations on teenagers with cleft lip and palate were evaluated. METHODS: Cleft lip and palate patients (aged 14 to 17 years; n = 55) and an age-matched unaffected cohort (n = 14) prospectively enrolled from two institutions were administered the anger, anxiety, and depressive symptoms instruments from the Pediatric Patient-Reported Outcomes Measurement Information System. Total number of operations and operations stratified by age groups (0 to 7, 8 to 10, 11 to 13, and 14 to 17 years) were evaluated in relationship to instrument scores. Descriptive statistics, independent t tests, Pearson correlations, and multiple linear regression analyses were conducted. RESULTS: No differences in overall psychosocial functioning were found between the cleft lip and palate and comparison groups. Total quantity of childhood operations did not correlate to psychosocial functioning of cleft lip and palate teenagers. However, multiple linear regression analyses demonstrated that increased number of operations in the 8- to 10-year-old age range predicted increased anxiety and depressive symptoms in teenagers (ß = 0.38, p = 0.009; and ß = 0.29, p = 0.03, respectively). CONCLUSIONS: It was previously reported by the authors' group that the 8- to 10-year-old age range is an at-risk period for psychosocial distress in children with craniofacial anomalies. Their current work demonstrates that increased number of operations during this time frame may result in long-term consequences in anxiety and depression in cleft lip and palate patients. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Discrepancies in Parent Perceptions and Patient-Reported Psychosocial Function in Children with Craniofacial Anomalies.

BACKGROUND: Understanding and optimizing psychosocial functioning in children with craniofacial anomalies are essential components of their reconstructive care. This work compared parental perceptions to pediatric self-reported psychosocial functioning in children with craniofacial anomalies. METHODS: Two hundred twenty-one children with craniofacial anomalies (aged 8 to 17 years) and their parents were prospectively evaluated at two institutions using the parent-proxy and pediatric Patient-Reported Outcomes Measurement Information System to assess anger, anxiety, depression, and peer relationships. Children were stratified into three age groups: group A, 8 to 10 years; group B, 11 to 13 years; and group C, 14 to 17 years. Pearson correlations, analyses of variance with post hoc comparisons under the Tukey criterion, and paired samples t tests were performed. RESULTS: When stratified by age, no correlations between parent and child reports were found in anxiety for group A and anger, anxiety, and peer relationships for group C. Whereas group A reported the worst psychosocial functioning, group C parents perceived their children to have the worst psychosocial functioning. Group A parents perceived lower depression and better peer relationships, whereas group C parents perceived higher anxiety and depression compared to self-reports. CONCLUSIONS: Parents perceived an inverse relationship between age and psychosocial functioning compared to self-reports by children with craniofacial anomalies. These discrepancies in the current work highlight the importance of child self-report and suggest incorporating longitudinal patient-reported and parent-proxy-reported outcomes measures for psychosocial functioning as part of standard clinical care for patients with craniofacial anomalies.

Orthognathic Consequences of Sphincter Pharyngoplasty in Cleft Patients: A 2-Institutional Study.

BACKGROUND: Understanding long-term sequelae of cleft treatment is paramount in the refinement of treatment algorithms to accomplish optimized immediate and long-term outcomes. In this study, we reviewed sphincter pharyngoplasties as a method of velopharyngeal insufficiency (VPI) treatment in relationship to orthognathic surgery. METHODS: Cleft lip/palate and cleft palate patients, 15 years of age and older, were reviewed for demographics, VPI surgery, revisions, and subsequent orthognathic surgery at 2 institutions. Chi-square test, Student's t test, and logistic regression analyses were performed. RESULTS: In 214 patients reviewed (mean age, 19.5 years), 61.7% were male, 18.2% had isolated cleft palate, 61.2% had unilateral cleft lip and palate, and 20.6% had bilateral cleft lip and palate. A total of 33.6% were diagnosed with VPI and received a sphincter pharyngoplasty (mean age, 11.9 years). When subsequent orthognathic surgery was examined, sphincter pharyngoplasty was not associated with maxillary advancement (P = 0.59) but did correlate with an increase in mandibular surgery from 2.8% to 11.1% (P = 0.02). The indications for mandibular surgery in the pharyngoplasty population were related to congenital micrognathia. When cephalometric analyses were evaluated, sphincter pharyngoplasty resulted in a decreased sella-to-nasion-to-B point angle (mean, 79.0-76.3 degrees, P = 0.02) and a higher incidence of normal to class II maxillomandibular relationships as defined by A point-to-nasion-to-B point angles >0.5 (P = 0.02). CONCLUSIONS: Sphincter pharyngoplasty decreases anterior mandibular growth and the discrepancy between maxillomandibular skeletal relationships because of the frequent predisposition of cleft patients to maxillary hypoplasia. In patients with congenital mandibular micrognathia, a small increase in mandibular surgeries may occur.

Best evidence topic report. Aspirin and the risk of intracranial complications following head injury.

A short cut review was carried out to establish whether pre-injury aspirin increases the risk of intracranial complications following head injury. 124 papers were found using the reported searches, of which three presented the best evidence to answer the clinical question. The author, date, and country of publication, patient group studied, study type, relevant outcomes, results, and study weaknesses of these best papers are tabulated. It is concluded that aspirin may increase the risk of developing intracranial complications. More research is needed.

Repair of alveolar cleft defects: reduced morbidity with bone marrow stem cells in a resorbable matrix.

Harvest of the autogenous iliac crest bone graft for an alveolar cleft defect (the gold standard) may cause short- and long-term pain and sensory disturbances. To determine if a tissue engineering technique with similar bone healing results offered decreased morbidity, we compared techniques for postoperative donor site pain. Traditional iliac crest bone graft had more donor site complications compared with both tissue engineering and minimally invasive iliac crest bone graft. With donor site pain, traditional had the most patients with pain and tissue engineering had the least patients with pain at all time points. The mean pain score, including both intensity and pain frequency, was greatest at all time points in traditional and least at all time points in tissue engineering. Closure of alveolar cleft defects with a resorbable collagen sponge and bone marrow stem cells resulted in reduced donor site morbidity and decreased donor site pain intensity and frequency.

Improved outcomes in cleft patients with severe maxillary deficiency after Le Fort I internal distraction.

BACKGROUND: Correction of severe maxillary deficiency in cleft lip-cleft palate patients often results in undercorrection, relapse, and need for secondary corrective procedures. Le Fort I internal distraction osteogenesis offers an alternative to one-step orthognathic advancement, with advantages of gradual lengthening through scar and earlier treatment in growing patients. METHODS: Patients with cleft lip-cleft palate deformities and maxillary deficiency were divided into three groups treated by Le Fort I advancement: group 1, mild to moderate deficiency (< 10 mm) with conventional orthognathic procedure; group 2, severe deficiency (> or = 10 mm) with conventional orthognathic procedure; and group 3, distraction procedure for severe deficiency (> or = 10 mm) (n = 51). Preoperative, postoperative, and follow-up (> 1 year) lateral cephalogram measurements were compared including angular (SNA and SNB) and linear (Deltax = horizontal and Deltay = vertical) changes. The Pittsburgh Speech Score was used to assess for velopharyngeal insufficiency (score > 3). RESULTS: Results demonstrated that group 1 patients had a mean SNA change from preoperatively (78.7) to postoperatively (83.8), and a horizontal change of 5.0 mm, with no relapse. Group 2 patients had a mean SNA change from preoperatively (76.3) to postoperatively (82.0) and a horizontal change of 7.2 mm, with 63 percent relapse. Group 3 patients had a mean SNA change from preoperatively (74.1) to postoperatively (84.9) and a horizontal change of 16.5 mm, with 15 percent relapse. Thus, for severe maxillary deficiency, the distraction group had 48 percent less relapse than the conventional Le Fort I group. Postoperative speech evaluation showed velopharyngeal insufficiency in the following: group 1, four of 20 patients (20 percent); group 2, nine of 11 patients (82 percent); and group 3, nine of 20 patients (45 percent). CONCLUSION: These data suggest that Le Fort I internal distraction for severe cleft maxillary deficiency leads to better dental occlusion, less relapse, and better speech results.

Genioplasty distraction osteogenesis and hyoid advancement for correction of upper airway obstruction in patients with Treacher Collins and Nager syndromes.

BACKGROUND: Treacher Collins and Nager syndromes may present with mandibular hypoplasia that causes posterior collapse of the tongue base and a decreased oropharyngeal airway. Mandibular distraction and orthognathic advancement are effective treatments to correct the airway, but failure may occur despite achieving class I occlusion. For this select population, the authors propose a novel procedure of genioplasty distraction and hyoid advancement to optimize epiglottal positioning. METHODS: Patients diagnosed with Treacher Collins (n = 5) or Nager syndrome (n = 3) with obstructive sleep apnea or tracheostomy dependency (n = 8) underwent genioplasty distraction and hyoid advancement. Airway outcome was assessed by preoperative and 1-year follow-up comparison of (1) laryngobronchoscopy, (2) sleep studies, and (3) tracheostomy dependency. For genioplasty outcome, three groups were used: group I (distraction genioplasty, syndromic) (n = 8), group II (acute genioplasty, syndromic) (n = 7), and group III (acute genioplasty, nonsyndromic) (n = 10). Lateral cephalogram measurements were used in the preoperative, postoperative, and follow-up periods to assess horizontal and vertical advancement and relapse. RESULTS: Epiglottal position was optimized by the procedure in all patients based on direct endoscopic assessment. All five patients with obstructive sleep apnea had resolution of symptoms, and two of three patients achieved removal of their tracheostomy. Mean advancement for groups I, II, and III was 25, 14, and 8 mm, respectively. Follow-up horizontal advancement for groups I, II, and III were 18, 4, and 6 mm, respectively. Cephalometric measurements showed a horizontal relapse for groups I, II, and III of 10, 62, and 11 percent, respectively. CONCLUSIONS: Data suggest that genioplasty distraction allows for a greater advancement and decreased relapse rate than acute procedures alone; and genioplasty distraction with hyoid advancement is a useful technique for resolution of obstructive sleep apnea or to achieve tracheostomy removal in those syndromic patients who have already undergone mandibular advancement into a class I occlusion.

International Task Force on Volunteer Cleft Missions.

The International Task Force on Volunteer Cleft Missions was set up to provide a report to be presented at the Eighth International Congress of Cleft Palate and Associated Craniofacial Anomalies on September 12, 1997, in Singapore. The aim of the report was to provide data from a wide range of different international teams performing volunteer cleft missions and, thereafter, based on the collected data, to identify common goals and aims of such missions. Thirteen different groups actively participating in volunteer cleft missions worldwide were selected from the International Confederation of Plastic and Reconstructive Surgery's list of teams actively participating in volunteer cleft missions. Because of the time frame within which the committee had to work, three groups that did not respond by the stipulated deadline were omitted from the committee. The represented members and their respective institutions have undertaken more than 50 volunteer cleft missions to underdeveloped nations worldwide within the last 3 years. They have visited over 20 different countries, treating more than 3,500 patients worldwide. Based on the data collected and by consensus, the committee outlined recommendations for future volunteer cleft missions based on 1) mission objectives, 2) organization, 3) personal health and liability, 4) funding, 5) trainees in volunteer cleft missions, and 6) public relations. The task force believed that all volunteer cleft missions should have well-defined objectives, preferably with long-term plans. The task force also decided that it was impossible to achieve a successful mission without good organization and close coordination. All efforts should be made, and care taken, to ensure that there is minimal morbidity and no mortality. Finally, as ambassadors of goodwill and humanitarian aid, the participants must make every effort to understand and respect local customs and protocol. The main aims are to provide top-quality surgical service, train local doctors and staff, develop and nurture fledgling cleft programs, and, finally, make new friends.
