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. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Evaluation of Helmeting Therapy Duration After Endoscopic Strip Craniectomy for Metopic and Sagittal Craniosynostosis.

INTRODUCTION: Endoscopic strip craniectomy (ESC) is a minimally invasive option for early surgical treatment of metopic (MC) and sagittal craniosynostosis (SC). For ESC, however, the postoperative duration and compliance of helmet therapy are crucial to correct MC and SC asymmetry. The purpose of this study is to assess the period of postoperative band therapy and determine differences, if any, between MC and SC. METHODS: A single-institution retrospective review was performed for patients with MC and SC who underwent ESC from November 2015 to 2019. Patients received preoperative, postoperative, and post-band 3-dimensional imaging. Factors recorded included patient sex, insurance type, number of helmets needed, age at surgery, time of first helmet, and at time of completion of helmet therapy, cephalic index, interfrontal angle, and cranial vault asymmetry index. RESULTS: Patients with SC and MC had ESC surgery at 3.3 and 3.4 months of age, respectively.Patients with SC were found to have completed banding therapy at a younger age (7.88 versus 10.0 mo), with shorter duration (4.17 versus 6.00 mo), and less number of bands (1.54 versus 2.21) than patients with MC. After regression analysis, suture type was found to be a significant predictor of total time in band therapy (P=0.039) with MC requiring a longer duration of banding therapy when compared with SC. CONCLUSIONS: Suture type directly correlates with duration of helmeting therapy for patients, with patients with MC requiring longer periods of postop helmeting and increased number of bands as compared with SC.

Predictive Factors for Velopharyngeal Insufficiency Following Primary Cleft Palate Repair.

OBJECTIVE: Velopharyngeal insufficiency (VPI) remains a known complication of primary palatoplasty. We sought to identify factors associated with the incidence of VPI and create a predictive model for VPI development in our population. DESIGN: A single-institution, retrospective review. SETTING: Multidisciplinary clinic in a tertiary academic institution. PATIENTS: A total of 453 consecutive patients undergoing primary palatoplasty from 1999 to 2016 were reviewed. Inclusion required follow-up past age 5. Patients who were non-verbal, and thus unable to undergo speech evaluation, were excluded. MAIN OUTCOME MEASURES: Primary outcome was VPI, defined as revision palatoplasty or recommendation by speech-language pathology. RESULTS: Of 318 patients included, 179 (56%) were male. Median age at primary repair was 1.0 years (0.9-1.1) with a median age of 8.8 years at last follow-up. One hundred nineteen (37%) patients developed VPI at a median age of 5.0 years (3.8-6.5). Higher rates were seen with posterior fistula (65% vs 14%, P <.01) and straight-line repair (41% vs 9%, P <.01), with lower rates in patients with Veau I clefts (22% vs 39%, P <.05). Patients with VPI were older at last follow-up. Following multivariate regression, factors remaining significant were posterior fistula (odds ratio [OR]: 11.3, 95% CI: 6.1-22.0), primary Furlow repair (OR: 0.18, 95% CI: 0.03-0.68), genetic diagnoses (OR: 2.92, 95% CI: 1.1-7.9), and age at last follow-up (OR: 1.11, 95% CI: 1.01-1.2). CONCLUSIONS: Length of follow-up, posterior fistulae, and genetic diagnoses are associated with VPI formation. Furlow repair may protect against formation of VPI. Use of allograft, Veau class, birth type, birth weight, and race are not independently associated with VPI formation.

Enhanced Recovery After Surgery Protocol for Primary Cleft Palate Repair: Improving Transition of Care.

BACKGROUND: Enhanced recovery after surgery (ERAS) protocols have been adopted for many types of surgery. Postoperative pain following palatoplasty may cause feeding and swallowing difficulty. Our study evaluated the use of ERAS protocols to improve the management of pain following primary palatoplasty as well as in the transition of care from inpatient to outpatient. METHODS: An Institutional Review Board approved retrospective analysis was performed for patients who previously underwent primary palatoplasty before ERAS implementation. Separately, an Institutional Review Board approved prospective trial of patients undergoing primary palatoplasty was performed and these patients were managed with ERAS protocols. Data were obtained for length of stay, pain scale scores, milligrams of morphine administered, and inpatient readmissions/emergency department visits. Outpatient medication logs were used to follow pain medicine usage, and a satisfaction survey was administered at the first postoperative visit. RESULTS: Data were obtained retrospectively for 56 patients and prospectively for 57 patients who underwent primary palatoplasty. Patients in the ERAS protocol received significantly less milligrams of morphine on postoperative day 1 through day 4 than those patients in the usual care group P < 0.05. No significant difference was observed for length of stay, oral intake prior to discharge, or inpatient face, legs, activity, cry, consolability pain scale scores. Outpatient medication logs showed a continued decrease in narcotic usage at home with no spike post discharge day 1. Parents reported high satisfaction levels for inpatient pain management (4.66 ±â€Š0.49) and even higher satisfaction levels for understanding (5.0 ±â€Š0) and management of pain at home (4.92 ±â€Š0.29). Return visits to the hospital for pain management following primary palatoplasty decreased from 7.1% (4) following the previous protocol to 0% with the new ERAS protocol (P = 0.057). CONCLUSION: The ERAS protocols provide improved inpatient pain management following primary palatoplasty as evidence by decreased total narcotic pain medication usage. The use of multimodality therapy and increased patient education regarding non-narcotic medications can improve the transition of care from inpatient to outpatient, without sacrificing patient/parent satisfaction. The results of this study merit future study into more restricted use of opioid pain medications with greater emphasis on the use of multimodal therapeutics as primary agents as opposed to adjuncts.

The Epidemiology and Management of Pediatric Maxillary Fractures.

BACKGROUND: Most literature regarding traumatic Le Fort or maxillary fractures exists in the adult population, with limited information regarding the epidemiology and management of pediatric fractures. The purpose of this study was to evaluate fracture mechanism, surgical management, and associated injuries in pediatric patients with Le Fort fractures. METHODS: A retrospective chart analysis of all pediatric patients age ≤18 years diagnosed with facial fractures at a single level 1 trauma center over a 10-year period (January 2006-December 2015) was performed. Demographics, fracture location, mechanism of injury, and hospital course were abstracted as well as associated injuries and need for operative management. RESULTS: A total of 1274 patients met inclusion criteria. Sixty-nine (5.4%) presented with Le Fort fractures. Factors associated with Le Fort fractures included motor vehicle collisions (P < 0.001), increased age (P < 0.001), and traumatic brain injury (P < 0.04). Patients with Le Fort fractures were more likely to need intensive care unit admission (P < 0.001), surgical management (P < 0.001), transfusions (P < 0.001), secondary fixation surgery (P < 0.001), and have a longer length of stay (P < 0.001). Multivariate showed increased odds for increased age (OR 1.1; 95%CI 1.04-1.17) and concomitant orbit fractures (OR 8.33; 95%CI 4.08-19.34). Decreased odds were associated for all mechanisms of injury other than motor vehicle collisions (Other blunt trauma: OR 0.36; 95%CI 0.2-0.6. Penetrating trauma: OR 0.13; 95%CI 0.01-0.6). CONCLUSION: Maxillary or Le Fort fractures represent a small portion of pediatric facial fractures but require high rates of operative management. The high velocity required to create this fracture type is associated with significant traumatic comorbidities, which can complicate the hospital course.

Impact of Cardiac Risk Factors in the Postsurgical Outcomes of Patients With Cleft Lip.

ABSTRACT: Congenital cardiac comorbidities represent a potentially elevated risk for complications in patients undergoing cleft lip repair. National databases, such as the National Surgical Quality Improvement Program Pediatric (NSQIP-P) allow for analysis of large national datasets to assess these risks and potential complications. The aim of this study is to assess the risk of complications in patients undergoing cleft lip repair with congenital cardiac co-morbidities using the NSQIP-P.The 2012 to 2014 NSQIP-P databases were queried for patients undergoing cleft lip repair. Data abstracted for analysis included demographic, clinical, and outcomes data. Patients with cleft lip were stratified based on the presence or absence of congenital cardiac comorbidities. Univariate analysis and step-wise, forward logistic regression were performed to compare these groups.Nationally, between 2012 and 2014, 2126 patients underwent cleft lip repair, 227 with cardiac disease, and 1899 without cardiac disease. Weights were similar between the groups at the time of surgery, though patients with cardiac comorbidities were older. Postoperatively, cardiac disease patients were more likely to experience an adverse event. Specifically, they were more likely to experience reintubation, reoperation, longer length of stay, and death. Rates of surgical site infection and dehiscence were not different between the groups.This study demonstrates that cleft lip repair in patients with congenital heart defects is safe. However, patients undergoing cleft lip repair with comorbid congenital cardiac disease were more likely to experience adverse events. Cardiac patients require special preoperative evaluation before repair of their cleft lip, but do not appear to experience worse wound-related outcomes.

Is Less Actually More? An Evaluation of Surgical Outcomes Between Endoscopic Suturectomy and Open Cranial Vault Remodeling for Craniosynostosis.

BACKGROUND: Both open cranial vault remodeling (CVR) and endoscopic suturectomy are effective in treating the anatomical deformity of craniosynostosis. While parents are increasingly knowledgeable about these 2 treatment options, information regarding the perioperative outcomes remains qualitative. This makes preoperative counseling regarding surgical choices difficult. The purpose of this study was to evaluate the outcomes in patients with craniosynostosis who underwent traditional CVR versus endoscopic suturectomy. METHODS: Open and endoscopic craniosynostosis surgeries performed at our institution from January 2014 through December 2018 were retrospectively reviewed and perioperative data, including operative time, estimated blood loss, transfusion rate and length of stay, was analyzed. A student t test was used with significance determined at P < 0.05. RESULTS: CVR was performed for 51 children while 33 underwent endoscopic procedures. Endoscopic suturectomy was performed on younger patients (3.8 versus 14.0 months, P < 0.001), had shorter operative time (70 versus 232 minutes, P < 0.001), shorter total anesthesia time (175 versus 352 minutes, P < 0.001), lower estimated blood loss (10 versus 28 ml/kg, P < 0.001), lower percentage transfused (42% versus 98%, P < 0.001), lower transfusion volume (22 versus 48 ml/kg, P < 0.001), and shorter length of stay (1.8 versus 4.1 days, P < 0.001) when compared to open CVR. CONCLUSION: Both open CVR and endoscopic suturectomy are effective in treating deformities due to craniosynostosis. The endoscopic suturectomy had significantly shorter operative and anesthesia time as well as overall and PICU length of stay. CVR was associated with greater intraoperative blood loss and more frequently required higher rates of blood transfusions.

Cervical Spine Injuries in Pediatric Maxillofacial Trauma: An Under-Recognized Problem.

Pediatric cervical spine injuries (CSI) are uncommon events, but can be devastating injuries. Facial fractures have been associated with injuries to the cervical spine in children, but may be deemed isolated facial fractures and bypass the standard trauma pathway. The objective of this study is to describe the mechanisms, associated injuries and outcomes of pediatric cervical spine injuries in patients with known maxillofacial trauma at a level 1 trauma center. An analysis was performed of all patients under the age of 18 with maxillofacial trauma admissions to a single level 1 trauma center, from 2006 to 2015. Patients were stratified based on the presence or absence of a cervical spine injury. Data was abstracted to include demographic, mechanism and clinical outcomes data. There were 1274 patients who were admitted with maxillofacial trauma during the study period. Of these, 72 (5.7%) experienced a cervical spine injury. Factors associated with cervical spine injuries include older age and penetrating mechanism. Cervical spine injuries were associated with concomitant traumatic brain injuries and skull fractures. Patients with spine injuries were more like to experience a longer length of stay and death. On multivariate analysis, only increased age predicted CSI. Our database demonstrated a 5.7% incidence of pediatric cervical spine injuries in patients with maxillofacial trauma. This incidence is higher than previously published reports of smaller cohorts. Clinicians must take care to stabilize the cervical spine in any patient with facial fractures, especially during work up and diagnostic maneuvers performed before spinal injuries are ruled out.

PBX-WNT-P63-IRF6 pathway in nonsyndromic cleft lip and palate.

Nonsyndromic cleft lip and palate (NSCLP) is one of the most common craniofacial anomalies in humans, affecting more than 135,000 newborns worldwide. NSCLP has a multifactorial etiology with more than 50 genes postulated to play an etiologic role. The genetic pathway comprised of Pbx-Wnt-p63-Irf6 genes was shown to control facial morphogenesis in mice and proposed as a regulatory pathway for NSCLP. Based on these findings, we investigated whether variation in PBX1, PBX2, and TP63, and their proposed interactions were associated with NSCLP. Fourteen single nucleotide variants (SNVs) in/nearby PBX1, PBX2, and TP63 were genotyped in 780 NSCLP families of nonHispanic white (NHW) and Hispanic ethnicities. Family-based association tests were performed for individual SNVs stratified by ethnicity and family history of NSCLP. Gene-gene interactions were also tested. A significant association was found for PBX2 rs3131300 and NSCLP in combined Hispanic families (p = .003) while nominal association was found for TP63 rs9332461 in multiplex Hispanic families (p = .005). Significant haplotype associations were observed for PBX2 in NHW (p = .0002) and Hispanic families (p = .003), and for TP63 in multiplex Hispanic families (.003). An independent case-control group was used to validate findings, and significant associations were found with PBX1 rs6426870 (p = .007) and TP63 rs9332461 (p = .03). Gene-gene interactions were detected between PBX1/PBX2/TP63 with IRF6 in NHW families, and between PBX1 with WNT9B in both NHW and Hispanic families (p < .0018). This study provides the first evidence for a role of PBX1 and PBX2, additional evidence for the role of TP63, and support for the proposed PBX-WNT-TP63-IRF6 regulatory pathway in the etiology of NSCLP.

Factors Associated With Surgical Management for Pediatric Facial Fractures at a Level One Trauma Center.

Pediatric facial fractures present and are managed differently than the adult population. This study describes the pattern and mechanism of facial fractures in children and identifies factors associated with need for surgical management. An IRB-approved retrospective chart analysis of all pediatric patients age ≤ 18 years diagnosed with facial fractures at our level 1 trauma center over a 10-year period (January 2006-December 2015) was performed. Demographics, fracture location, mechanism of injury, concomitant head and neck injuries, and surgical management were reviewed. Statistical analysis was then performed comparing surgical and nonsurgical cohorts using univariate and multivariate analyses. One thousand two hundred seventy-four patients were diagnosed with facial fractures. Five hundred seventeen (40.6%) underwent surgical management. Two thousand one hundred seventy-two total facial fractures were recorded. Orbit fractures (29%) were the most commonly recorded, observed in 49% of patients presenting. Increased age was associated with increased odds of surgical management (OR 1.13; 95% CI 1.09-1.16). Mandible (OR 9.28; 95% CI 6.88-12.51) and Le Fort fractures (OR 19.73; 95% CI 9.78-39.77) had increased odds of surgical management. Patients with traumatic brain injury had reduced odds (OR 0.54; 95% CI 0.35-0.83) of surgical management for their facial fractures. Older pediatric patients may be more likely to require surgical management of their facial fractures, especially those with mandible or Le Fort fractures. Patients with traumatic brain injury are likely to sustain life threatening injuries, deferring repair of their facial fractures. Patient education and counseling, as well as predictive models, can be improved to reflect these data.

The Trends of Pediatric Facial Fractures Due to Violence in a Level One Trauma Population.

INTRODUCTION: Pediatric facial fractures due to intentionally violent mechanisms represent a unique subset of facial fractures. The objective of our research is to identify how violence affects patterns of facial fractures and their management in pediatric patients. METHODS: An IRB approved, retrospective study of our institution's pediatric patients ≤18 years of age who presented with ≥1 facial fracture due to violence from January 2006 to December 2015 was performed. Violence was defined as trauma intended to hurt another or self. Demographics, fractures, mechanism, concomitant injuries, and management were analyzed. RESULTS: The 1274 patients were diagnosed with facial fractures, with 235 of these due to violence (18%). These patients of violence (POV) had 332 fractures, with an average fracture per patient of 1.4 ±â€Š.0.8. The majority (86%) were male, Non-Hispanic African American (35%), and the average age was 15.9 ±â€Š2.8 years. The most common fracture was the mandible (50% of patients) and most common mechanism was assault (76%). The POV were older, male, and of minority race/ethnic groups when compared to patients of non-violence (PONV) (P <0.01). The POV presented with fewer concomitant injuries, were less likely to be admitted to the intensive care unit, and more often surgically managed when compared to the PONV (P <0.01). CONCLUSION: This study represents the largest US, single institution, Level 1 trauma center study of pediatric facial fractures. Pediatric patients with facial fractures due to a violent mechanism represent a distinct category of trauma patients with a unique profile of injuries.

Impact of Cardiac Risk Factors in the Postsurgical Outcomes of Patients With Cleft Palate: Analysis of the 2012-2014 NSQIP Database.

OBJECTIVE: To assess the risk of complication in patients undergoing cleft palate repair with congenital cardiac comorbidities in a large, national cohort. DESIGN: Retrospective review. PATIENTS/SETTING: Using the 2012-2014 National Surgical Quality Improvement Program (NSQIP) Pediatric database, patients undergoing cleft palate repair were selected for analysis. Patients with cleft palate repairs were stratified based on the presence or absence congenital cardiac comorbidities. Univariate and stepwise forward logistic regression were conducted. MAIN OUTCOME MEASURES: It is hypothesized that risk of postoperative adverse events in patients with congenital cardiac comorbidities is higher than in patients without cardiac disease. RESULTS: Nationally, between 2012 and 2014, 3240 patients underwent cleft palate repair, 422 (13.0%) with cardiac disease, and 2818 (87.0%) without cardiac disease. Patients with cardiac disease were smaller (10.5 [6.6] kg vs 11.6 [8.6] kg, P < .01) and more likely to be premature (4.6% vs 13.0%, P < .01) compared to those without cardiac disease. Postoperatively, patients with cardiac conditions were more likely to experience an adverse event (8.8% vs 4.2%, P < .01). Specifically, they were more likely to experience reintubation (1.7% vs 0.4%, P < .01), reoperation (2.1% vs 0.6%, P < .01), and longer length of stay (2.7 [7.0] vs 1.6 [2.8] days, P < .01). Rates of surgical site infection and dehiscence were not different. CONCLUSIONS: Cleft palate repair in patients with concurrent congenital cardiac defects is a safe procedure but carries elevated risk in the postoperative period as demonstrated in this analysis of the NSQIP-Pediatric database. Technical risks are equivalent. Additional anesthesia and surgical awareness of these potential complications is essential to minimize perianesthesia risks.

Both the Observer's Expertise and the Subject's Facial Symmetry Can Affect Anatomical Position of the Head.

PURPOSE: It is easier to judge facial deformity when the patient's head is in anatomic position. The purposes of this study were to determine 1) whether a group of expert observers would agree more than a group of nonexperts on what is the correct anatomic position of the head, 2) whether there would be more variation in the alignment of an asymmetrical face compared with a symmetrical one, and 3) whether the alignments of experts would be more repeatable than those of nonexperts. MATERIALS AND METHODS: Thirty-one orthodontists (experts) and 31 dental students (nonexperts) were recruited for this mixed-model study. They were shown randomly oriented 3-dimensional head photographs of an adult with a symmetrical face and an adolescent with an asymmetrical face. In viewing software, the observers oriented the images into anatomic position. They repeated the orientations 4 weeks later. Data were analyzed using a generalized linear model and Bland-Altman plots. The primary predictor variables were experience and symmetry status. The outcome variable was the anatomic position of the head. The other variables of interest included time and orientation direction. RESULTS: There was a statistically significant difference between measurements completed by experts and nonexperts (F1,60 = 14.83; P < .01). The interaction between expertise and symmetrical status showed a statistically significant difference between symmetrical and asymmetrical faces in the expert and nonexpert groups (F1,60 = 9.93; P = .003). The interaction between expertise and time showed a statistically significant difference in measurement over time in the expert and nonexpert groups (F1,60 = 4.66; P = .03). CONCLUSIONS: The study shows that experts can set a head into anatomic position better than nonexperts. In addition, facial asymmetry has a profound effect on the ability of an observer to align a head in the correct anatomic position. Moreover, observer-guided alignment is not reproducible.

Assessing Burden of Care in the Patient With Cleft Lip and Palate: Factors Influencing Completion and Noncompletion of Nasoalveolar Molding.

OBJECTIVE: Evaluate the factors that influence caregiver-reported completion of nasoalveolar molding (NAM) therapy for patients with cleft lip and palate. DESIGN: An IRB-approved 30-question survey. SETTING: Outpatient clinic for patients with cleft lip. PATIENTS: Patients with unilateral or bilateral cleft lip treated with NAM therapy. INTERVENTIONS: Survey of previous experiences. MAIN OUTCOME MEASURE(S): Rate of noncompletion for patients initiating NAM therapy and identifiable causes. RESULTS: Of 94 patients who underwent NAM, 13 (13.8%) failed to complete NAM therapy. Reasons for incomplete treatment included: obstructive sleep apnea, device intolerance, tape issues, and lack of support. Patients who did not complete NAM therapy were less likely to have primary caregivers >30-year old (P = .045) and more likely to be the first child for the family (P = .021) and have a bilateral cleft (P = .03). Caregivers of NAM patients were less satisfied with the outcome (P < .001) when they did not complete therapy. CONCLUSION: This study shows that a high number of parents fail to complete this therapy for many reasons, personal and medical. More data are needed to elucidate true prevalence of NAM noncompletion and to establish evidence-based guidelines to reduce barriers to care for completing NAM treatment.

Knockdown of Crispld2 in zebrafish identifies a novel network for nonsyndromic cleft lip with or without cleft palate candidate genes.

Orofacial development is a multifaceted process involving tightly regulated genetic signaling networks, that when perturbed, lead to orofacial abnormalities including cleft lip and/or cleft palate. We and others have shown an association between the cysteine-rich secretory protein LCCL domain containing 2 (CRISPLD2) gene and nonsyndromic cleft lip with or without cleft palate (NSCLP). Further, we demonstrated that knockdown of Crispld2 in zebrafish alters neural crest cell migration patterns resulting in abnormal jaw and palate development. In this study, we performed RNA profiling in zebrafish embryos and identified 249 differentially expressed genes following knockdown of Crispld2. In silico pathway analysis identified a network of seven genes previously implicated in orofacial development for which differential expression was validated in three of the seven genes (CASP8, FOS, and MMP2). Single nucleotide variant (SNV) genotyping of these three genes revealed significant associations between NSCLP and FOS/rs1046117 (GRCh38 chr14:g.75746690 T > C, p = 0.0005) in our nonHispanic white (NHW) families and MMP2/rs243836 (GRCh38 chr16:g.55534236 G > A; p = 0.002) in our Hispanic families. Nominal association was found between NSCLP and CASP8/rs3769825 (GRCh38 chr2:g.202111380 C > A; p < 0.007). Overtransmission of MMP2 haplotypes were identified in the Hispanic families (p < 0.002). Significant gene-gene interactions were identified for FOS-MMP2 in the NHW families and for CASP8-FOS in the NHW simplex family subgroup (p < 0.004). Additional in silico analysis revealed a novel gene regulatory network including five of these newly identified and 23 previously reported NSCLP genes. Our results demonstrate that animal models of orofacial clefting can be powerful tools to identify novel candidate genes and gene regulatory networks underlying NSCLP.

Resorbable Plates in Secondary Cleft Nasal Reconstruction.

OBJECTIVE: The authors report on the use and complications of alloplastic resorbable plates and compare their use to autologous cartilage grafts in secondary cleft nasal reconstruction. DESIGN: Institutional review board (IRB)-approved retrospective chart review. SETTING: Texas Cleft-Craniofacial Center at the McGovern Medical School at the University of Texas Health Sciences Center at Houston. PATIENTS: Patients with unilateral or bilateral cleft lip nasal deformity who have undergone secondary correction of their nasal deformity with at least 1-year follow-up. INTERVENTIONS: During their reconstruction, some patients had cartilage grafts used for support, whereas others were reconstructed using resorbable plates. MAIN OUTCOME MEASURE(S): Complications (exposure, infection, malposition, hematoma/seroma) and rates of tertiary revisions. RESULTS: 197 patients underwent secondary cleft nasal reconstruction, with 30 patients in the resorbable plate group and 32 in the cartilage graft group. Age at surgery was 8.5±4.1 years with resorbable plates and 11.0±4.8 years with cartilage graft ( P = .03). Infection rate in the resorbable plate group and cartilage graft group were 0% and 3.25% ( P = 1). Extrusion occurred in 3 of the absorbable plate group and 2 patients with cartilage graft ( P = .67). Additional surgery was recorded in 43.3% of the resorbable plate group versus 53.1% of the cartilage graft group ( P = .459). CONCLUSION: The data provide evidence that the use of alloplastic resorbable plate in the pediatric population is a safe alternative to autologous septal cartilage in secondary cleft nasal reconstruction. There is no statistical difference in short-term complications or the incidence of additional nasal surgery.

Design, development and clinical validation of computer-aided surgical simulation system for streamlined orthognathic surgical planning.

PURPOSE: There are many proven problems associated with traditional surgical planning methods for orthognathic surgery. To address these problems, we developed a computer-aided surgical simulation (CASS) system, the AnatomicAligner, to plan orthognathic surgery following our streamlined clinical protocol. METHODS: The system includes six modules: image segmentation and three-dimensional (3D) reconstruction, registration and reorientation of models to neutral head posture, 3D cephalometric analysis, virtual osteotomy, surgical simulation, and surgical splint generation. The accuracy of the system was validated in a stepwise fashion: first to evaluate the accuracy of AnatomicAligner using 30 sets of patient data, then to evaluate the fitting of splints generated by AnatomicAligner using 10 sets of patient data. The industrial gold standard system, Mimics, was used as the reference. RESULT: When comparing the results of segmentation, virtual osteotomy and transformation achieved with AnatomicAligner to the ones achieved with Mimics, the absolute deviation between the two systems was clinically insignificant. The average surface deviation between the two models after 3D model reconstruction in AnatomicAligner and Mimics was 0.3 mm with a standard deviation (SD) of 0.03 mm. All the average surface deviations between the two models after virtual osteotomy and transformations were smaller than 0.01 mm with a SD of 0.01 mm. In addition, the fitting of splints generated by AnatomicAligner was at least as good as the ones generated by Mimics. CONCLUSION: We successfully developed a CASS system, the AnatomicAligner, for planning orthognathic surgery following the streamlined planning protocol. The system has been proven accurate. AnatomicAligner will soon be available freely to the boarder clinical and research communities.

Survey of Parent Experiences in Prenatal Visits for Infants With Cleft Lip and Palate.

OBJECTIVE: The purpose of this study was to identify the factors that influence the parent's choice of cleft team/surgeon. DESIGN: A 10-question survey was used to elucidate factors that influenced parents in choosing their cleft surgeon. No identifiers of the origin of the study were used to improve parent objectivity. SETTING: The setting for this study was an online survey. PARTICIPANTS: Participants in this study were the parents of children who were born with cleft lip and/or palate. INTERVENTIONS: Parents were contacted anonymously via national, established social media websites that were independently run by the parents themselves. MAIN OUTCOME MEASURES: The main outcome measures were information regarding choice of cleft team/surgeon, source of patient referrals, and use of online media in decision making. RESULTS: A total of 112 responses were received. Of the parents, 77% sought prenatal evaluation with at least one cleft surgeon. Maternal-fetal medicine specialists were the most frequent (42%) referral source, followed by primary obstetricians (14%) and pediatricians (12%). The surgeon/cleft team's experience level and overall personality were ranked as the most important, whereas the least important was distance traveled. Of the parents, 95% used the Internet or social media for research prior to their prenatal visit; 96% of the parents found the prenatal visit helpful, and the most useful topics discussed were treatments (surgical, nonsurgical) and feeding techniques. CONCLUSION: This study identifies factors used to choose a cleft team/surgeon. Parents are more concerned with the experience level, reputation, and environment of the cleft team/surgeon than the distance traveled to get to the center.

Cervical Instability in Pierre Robin Sequence: An Addition to the Algorithm.

Many patients with Pierre Robin sequence (PRS) have associated birth defects, most commonly in association with abnormalities in bone or cartilage formation. Depending on severity, treatment of PRS ranges from nonoperative management with prone positioning to surgical intervention such as distraction osteogenesis. Generally, if a surgical approach is needed, these patients undergo nasal endoscopy or direct laryngoscopy with their intubation, which puts the cervical spine in a position of extreme extension. The authors present a patient with syndromic PRS secondary to Sticklers syndrome, with a cervical abnormality diagnosed with three-dimensional computed tomography and further evaluated with dynamic lateral plain x-rays to assess cervical instability. The goal of this report is to highlight the need to include cervical spine evaluation in the preoperation workup of patients with PRS, especially those with suspected abnormalities in bone or collagen formation.

An Outcomes Comparison Between Autologous and Alloplastic Cranioplasty in the Pediatric Population.

BACKGROUND: The use of alloplastic material in cranial reconstruction has been well described in the adult population, especially when a paucity of autologous tissue exists. In children it is unknown how long-term growth, however, may be affected by the implantation of nonexpansible alloplastic material. Therefore, the authors sought to compare the outcomes of pediatric patients undergoing alloplastic versus autologous cranial reconstruction. METHODS: To assess the safety and long-term outcomes of alloplastic cranioplasty in children, an institutional review board-approved, retrospective, single institution review of pediatric patients undergoing cranioplasty was performed from 2000 to 2014. The age at surgery, cause of the cranial defect, defect size, time since initial surgery to reconstruction, implant type, and complications were assessed. Postreconstruction imaging was reviewed if available. RESULTS: A reconstructive cranioplasty was performed in 41 pediatric patients (ages 1-19 years, average 7.35 years). Thirty patients underwent alloplastic reconstruction (age 4.37 ±â€Š5.57 years), and 11 underwent autologous reconstruction (age 2.00 ±â€Š3.74 years). The size of the cranial defects was 144.01 ±â€Š393.04 cm for autologous and 405.31 ±â€Š572.96 cm for alloplastic reconstructions. Follow-up for all patients was an average of 2.33 ±â€Š2.76 years (0.1-9 years). No patients in either group showed evidence of elevated intracranial pressure after cranioplasty. In long-term follow-up, none of the implants were exposed or lost because of infection. Computed tomography and physical examination demonstrated that there was no skull growth restriction in either group. CONCLUSIONS: Our data show that alloplastic cranioplasty in the pediatric population is a safe alternative, when autologous cranial bone is not available.
