RESUMO
The current standard of care for an alveolar cleft defect is an autogenous bone graft, typically from the iliac crest. Given the limitations of alveolar bone graft surgery, such as limited supply, donor site morbidity, graft failure, and need for secondary surgery, there has been growing interest in regenerative medicine strategies to supplement and replace traditional alveolar bone grafts. Though there have been preliminary clinical studies investigating bone tissue engineering methods in human subjects, lack of consistent results as well as limitations in study design make it difficult to determine the efficacy of these interventions. As the field of bone tissue engineering is rapidly advancing, reconstructive surgeons should be aware of the preclinical studies informing these regenerative strategies. We review preclinical studies investigating bone tissue engineering strategies in large animal maxillary or mandibular defects and provide an overview of scaffolds, stem cells, and osteogenic agents applicable to tissue engineering of the alveolar cleft. An electronic search conducted in the PubMed database up to December 2021 resulted in 35 studies for inclusion in our review. Most studies showed increased bone growth with a tissue engineering construct compared to negative control. However, heterogeneity in the length of follow up, method of bone growth analysis, and inconsistent use of positive control groups make comparisons across studies difficult. Future studies should incorporate a pediatric study model specific to alveolar cleft with long-term follow up to fully characterize volumetric defect filling, cellular ingrowth, bone strength, tooth movement, and implant support.

BACKGROUND/PURPOSE: Pediatric septorhinoplasty has sparked controversial debate amongst craniofacial surgeons, particularly due to its potential growth disturbances of the face and nose. The purpose of this study is (1) to conduct a systematic literature review that explores unique considerations and limitations associated with performing rhinoplasty in the pediatric population; (2) to discuss objective indicators for determining craniofacial skeleton maturation; (3) to perform a case series to further understand whether the age of menarche serves as a good proxy for estimating the time of facial growth maturation, and by extension, whether a post-menarchal patient is a suitable candidate for rhinoplasty. METHODS: Systematic literature review was performed in order to assess unique considerations and limitations of pediatric rhinoplasty. Retrospective chart review and anthropometric (9 linear, 3 angular, 6 indices) measurements were performed for ten pediatric female patients who underwent open septo-rhinoplasty. Follow-up times ranged from 66 to 103 weeks. Patients were separated into 2 cohorts according to age at the time of menarche. Cohort 1 consisted of patients who had undergone menses for longer than 2 years at the time of rhinoplasty, whereas Cohort 2 comprised of patients who either had menses within 2 years of rhinoplasty or did not have menses at the time of rhinoplasty. Data included demographic factors, procedural variables, revision surgeries, and complications. Measurements were conducted using VECTRA software (Canfield Scientific, Parsippany, NJ). Differences in measurements between the 2 postoperative timepoints were compared. RESULTS: Literature review yielded 17 articles, which had conflicting opinions regarding pediatric rhinoplasty and ultimately, highlighting the need for a more objective tool for guiding the decision to perform rhinoplasty.Patients in Cohort 1 had minimal deviations in measurements over time, within the exception of an increase in nasal tip projection and a decrease in nasolabial angle and facial width. Patients in Cohort 2 had decreases in facial height, upper facial height, nasal tip angle, and nasofrontal angle. Nasolabial angle decreased for both cohorts. Of the ten patients, 1 in Cohort 2 underwent revision rhinoplasty. CONCLUSIONS: Our case series suggests that anthropometric measurements remain relatively more stable for patients who have undergone menses for more than 2 years, compared to those who have not. Although this study has limitations, further investigation is warranted in order to determine whether age of menarche may serve as a useful tool for craniofacial surgeons in guiding the decision to perform rhinoplasty.

PURPOSE: Within the academic surgical setting resident involvement may confer longer operative times. The increasing pressures to maximize clinical productivity and decreasing reimbursement rates, however, may conflict with these principles. This study calculates the opportunity cost of resident involvement in craniofacial surgery. METHODS: Retrospective analysis was conducted with patients who underwent craniofacial procedures from the American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2012. Patients were selected based on relevant Current Procedural Terminology codes for craniofacial pathologies (ie, trauma, head and neck reconstruction, orthognathic surgery, and facial reanimation). Variables included patient demographics, operative time, and presence or absence of resident trainee. Average relative value units were calculated to determine the opportunity cost of resident involvement for each craniofacial procedure. RESULTS: In total, 2096 patients were identified through the American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2012. Resident involvement was associated with a statistically significant higher operative time (Pâ<â0.001) for facial reanimation, facial trauma, orthognathic surgery, and head and neck reconstruction. The opportunity costs per case associated with resident involvement were the highest for head and neck reconstruction ($1468.04), followed by orthognathic surgery ($1247.03), facial trauma ($533.03), and facial reanimation ($358.32). Resident involvement was associated with higher rate of complications for head and neck reconstruction (Pâ<â0.043). CONCLUSIONS: Resident involvement is associated with longer operative times, higher complications, and higher re-operations, compared to attending exclusive surgical care. Future studies may consider how reimbursements should align incentives to promote resident education and training.

PURPOSE: Patients born with a cleft palate often suffer from velopharyngeal insufficiency (VPI) due to the soft palate musculature's abnormal structure. Surgical correction of the palate at a young age can hinder maxillary growth, requiring surgical correction of the maxillomandibular discrepancy at skeletal maturity. Orthognathic surgery can then cause or further exacerbate VPi in these patients. The purpose of this paper is to assess cleft-orthog-nathic patients under the lens of persistent or newly-developed VPi, to understand outcomes and generate a targeted management algorithm. METHODS: A retrospective study was performed inspecting cleft-orthognathic patients presenting to a single surgeon. Patients with sufficient follow-up were placed into predefined algorithmic cohorts by their VPi development pattern in relation to orthognathic surgery. They were further stratified into groups by level of adherence to our algorithm to evaluate VPi outcomes. Demographic factors, risk factors, and outcomes were compared between groups via Welch t test and Fisher exact test. RESULTS: Fifty-one patients were examined, including 16 with VPI. Velopharyngeal insufficiency fully resolved amongst all algorithmically adherent patients and remained in nonadherent patients ( P â<â0.001). CONCLUSIONS: Our targeted algorithm may improve symptoms and the management of VPI in cleft-orthognathic patients. Multi-centered studies with larger sample sizes and prospective studies are encouraged to validate our proposed treatment algorithm further.

PURPOSE: The determination of facial growth maturity is crucial before surgical intervention in pediatric patients. To the author's knowledge, there are several indicators of skeletal maturity, but there remains a lack of consensus regarding their application when determining surgical timing. The purpose of this study was to determine the most accurate skeletal maturity indicator in predicting facial growth maturation. MATERIALS AND METHODS: A systematic review was done to determine the most predictive indicator for facial growth maturity. We hypothesized that menses' onset was the most predictive of these maturity indicators. This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A systematic search of MEDLINE, Cochrane, Embase, Scopus databases, and Google Scholar, was done in October 2020 to identify citations related to maturity indicators assessing craniofacial growth. The quality of evidence was determined using the Joanna Briggs Institute Critical Appraisal Checklist for Cohort Studies. RESULTS: Of the 13,289 articles screened, 1 retrospective and 1 prospective study met inclusion criteria. No articles were identified that provided evidence for our hypothesis. Based on the 2 included studies, it was concluded that a handwrist x-ray was more predictive of facial growth cessation (compared to other skeletal maturity indicators). CONCLUSIONS: Based on the literature, handwrist radiography serves as the most predictive method in determining the facial growth maturity. The paucity of articles within this investigation highlights the need for greater research efforts to investigate the predictability of indicators to evaluate facial growth maturation.

PURPOSE: The final result following orthognathic surgery may be hidden for months due to postoperative swelling. However, no substantial evidence supports this time estimate. Our study aims to three-dimensionally quantify volumetric changes in facial edema following triple-jaw surgery. MATERIALS AND METHODS: This was a retrospective, three-dimensional (3D) study of patients who underwent primary orthognathic triple jaw surgery (Le Fort I, Bilateral Sagittal Split Osteotomy (BSSO), and osseous genioplasty) by the senior author (DMS). Vectra 3D Software (Canfield, Fairfield, NJ) was used to assess and quantify volumetric changes between serial 3D photos. An inverse line of best-fit was plotted to assess reduction in postoperative facial edema. The effects of gender, age, body mass index, and tranexamic acid administration on swelling resolution were analyzed through mixed linear model analysis. RESULTS: A total of 46 patients (198 images) met the study criteria. The equation for the inverse function line of best fit was y = -13.14ln (x) + 39.54 (Pâ<â0.01). On average, 60% of the swelling resolved in 1âmonth, 84% after 6 months, and nearly 93% after 12âmonths. There were no significant differences in the rate of swelling resolution when accounting for age, gender, body mass index, or tranexamic acid administration. CONCLUSIONS: Most facial edema resolved during the first month following triple jaw surgery, with significant reduction in swelling between 6 and 12âmonths postoperatively. After 1 year, approximately 10% of the initial edema remained.

PURPOSE: Patients with significant dentofacial deformities undergoing aesthetic and functional orthognathic surgery may often require genioplasty to advance the position of the pogonion relative to B point. No study to date has evaluated nationally registered data pertaining to addition of osseous genioplasty to bimaxillary orthognathic surgery and its associated clinical outcomes. METHODS: Data was extracted from the National Surgical Quality Improvement Program from 2010 to 2018 using current procedural terminology codes pertaining to Le Fort I osteotomy (LF), bilateral sagittal split osteotomy (BSSO), and osseous genioplasty (G) and divided into 2 cohorts: bimaxillary orthognathic surgery with and without osseous genioplasty. Thirty-day postoperative outcomes inherently recorded within National Surgical Quality Improvement Program were identified and recorded. Chi-squared analysis and unpaired 2-tail t tests were performed between the cohorts and their respective outcomes to determine significant relationships with significance set as Pâ<â0.05. RESULTS: There were 373 patients double- or triple-jaw patients identified from the years 2010 to 2018. The most common recorded indication for LF/BSSO was maxillary hypoplasia (27.3%) and mandibular hypoplasia (6.8%). The most common indications for LF/BSSO/G were maxillary hypoplasia (16.1%) and maxillary asymmetry (16.1%). In comparison to LF/BBSO only, LF/BSSO/GP was not associated with any differences in the rate of surgical (0.0% versus 0.31%, Pâ=â0.72) or medical complications (0.0% versus 0.63%, Pâ=â0.60), in addition to unplanned readmissions (0.0% versus 1.56% versus Pâ=â0.41) or reoperations (0.0% versus 1.25%, Pâ=â0.46). However, osseous genioplasty addition was associated with increased overall operating time (271.77 versus 231.75 minutes, Pâ=â0.04). CONCLUSIONS: Osseous genioplasty does not alter short-term, 30-day complication rate when performed with bimaxillary orthognathic surgery. As reoperation rates remained relatively unchanged, it can be inferred that immediate adverse events or patient dissatisfaction were not apparent within 30âdays. Although mean operating time is slightly longer, cardiopulmonary resuscitation without medical comorbidity was achieved at the conclusion of the procedure.

ABSTRACT: Artificial intelligence (Al)-based analyses may serve as a more objective tool for measuring cosmetic improvements following aesthetic plastic surgery. This preliminary proof-of-concept study utilized a novel commercial facial recognition software to assess perceived changes in age and attractiveness among patients receiving rhinoplasty.This study was a retrospective evaluation of three-dimensional photographs of patients who underwent rhinoplasty by the senior author (DS). Both pre- and post-operative (> 12-month follow-up) Vectra three-dimensional images (Canfield Scientific, Parsippany, NJ) were assessed using Haystack AI Software (Haystack AI, New York, NY). Facial attractiveness (score 1-10) and apparent age were predicted. A retrospective chart review of demographic variables was additionally performed. Paired t tests were used to compare age and attractiveness scores before and after surgery. Multivariate linear regression was performed to identify factors associated with age and attractiveness scores.One hundred twenty-four patients receiving rhinoplasty met the study criteria (average age: 35.58). Overall, rhinoplasty was associated with increases in Al-rated attractiveness (+0.28, P = 0.03) and decreases in perceived age relative to the patient's true age (-1.03 years, P = 0.03). Greater decreases in postoperative perceived age were achieved in patients who appeared older than their actual age preoperatively ( P < 0.001).Facial recognition software was successfully used to evaluate improvements in perceived age and attractiveness in patients undergoing aesthetic rhinoplasty. Patients were perceived by the software as younger and more attractive following rhinoplasty. Age reversal was greatest among patients who appeared much older than their actual age at the time of surgery.Level of Evidence: IV.

Primary CL/P repair, revisions, and secondary procedures-cleft rhinoplasty, speech surgery, and alveolar bone grafting (ABG)-performed from 2014-2018 were identified from the Pediatric National Surgical Quality Improvement Program (NSQIP) database. Utilization estimates were derived via univariable and multivariable logistic regression. A Kruskal-Wallis rank-sum test and multivariable linear regression were used to assess differences in timing for each procedure cohort.The primary outcome measures were the odds of a patient being a certain race/ethnicity, and the age at which patients of different race/ethnicity receive surgery.There were 23â 780 procedures analyzed. After controlling for sex, diagnosis, and functional status, there were significant differences in utilization estimates across procedure groups. Primarily, utilization was lowest in patient who were Black for cleft rhinoplasty (OR = 0.70, P = .023), ABG (OR = 0.44, P < .001) and speech surgery (OR = 0.57, P = .012), and highest in patients who were Asian patients in all surgery cohorts (OR 2.05-4.43). Timing of surgery also varied by race, although differences were minimal. CONCLUSIONS: Estimates of utilization and timing of secondary cleft procedures varied by race, particularly among patients who were Black (poor utilization) or Asian (high utilization). Further studies should identify the causes and implications of underutilized and/or delayed cleft care.

PURPOSE: Older age cleft palate (CP) repair in international settings has been associated with increased surgical morbidity. This study assesses the prevalence and risks associated with late-age CP repair (age > 5 years) in the United States. METHODS: Primary CP repair patients less than the age of 18 years were identified in the National Surgical Quality Improvement pediatric database from 2012 to 2018. Total postoperative complications, readmissions, reoperations, duration of surgery, and length of stay were recorded. T-tests and χ2 analyses were used to compare variables between age groups 0-5, 6-10, and 11-17. RESULTS: A total of 10,022 primary CP procedures were identified from 2012 to 2018, of which 868 (8.6%) received repair at age > 5 years. Hispanic patients constituted a larger proportion of CP repair from ages 11 to 17 years than repair at other ages (P < .001). In comparison with children treated from ages 0 to 5 years, children operated on between ages 6 and 10 or 11 and 17 years experienced no increases in unplanned readmissions, reoperations, or complication rates after surgery. Patients of ages 6-10 years and 11-17 years had decreased operating room time (P < .001) compared with younger patients. Patients of ages 11-17 years also had decreased hospital length of stay (P = .04). CONCLUSIONS: Many children in the United States received primary CP repair after the age of 5 years likely due to late treatment of submucosal clefts or delayed care among international immigrants/adoptees. Old age procedures were not associated with increased short-term surgical morbidity in comparison with surgery at earlier time points. The causes and implications of older age primary surgery warrant further study.

PURPOSE: Children with cleft lip and/or palate (CLP) require longitudinal multidisciplinary care. Travel distance to comprehensive cleft centers may be a barrier for some families. This study evaluated the geospatial availability of certified cleft teams across the United States. MATERIALS AND METHODS: A geographic catchment area within a 1-hour travel radius of each American Cleft Palate-Craniofacial Association-certified cleft center was mapped using TravelTime distance matrix programming. The proportion of children located within each catchment area was calculated using county-level data from the National Kids Count Data Center, with aggregate estimates of patients with CLP based on state-level data from the Centers for Disease Control and Prevention. One-hour access was compared across regions and based on urbanization data collected from the US Census. RESULTS: There were 182 American Cleft Palate-Craniofacial Association-certified centers identified. As per study estimates, 28,331 (27.3%) children with CLP did not live within 1-hour travel distance to any center. One-hour access was highest in the Northeast (84.2% of children, P < .001) and lowest in the South (65.7%) and higher in states with the greatest urbanization in comparison with more rural states (85.1 vs 37.4%, P < .001). Similar patterns were seen for access to 2 or more cleft centers. The number of CLP children-per-center was highest in the West (775) and lowest in the Northeast (452). CONCLUSIONS: Travel distances of more than 1 hour may affect more than 25,000 (1 of 4) CLP children in the US, with significant variation across geographic regions. Future studies should seek to understand the impact of and provide strategies for overcoming geographic barriers.

INTRODUCTION: Black and Hispanic/Latino patients in the United States often experience poorer health outcomes in comparison to White patients. We aimed to assess the impact of race on complications, length of stay, and costs after orthognathic surgery. METHODS: Pediatric and young adult orthognathic surgeries (age <21) were isolated from the Kids Inpatient Database from 2000-2012. Procedures were grouped into cohorts based on the preoperative diagnosis: apnea, malocclusion, or congenital anomaly. T tests and χ2 analyses were employed to compare complications, length of stay (LOS), and costs among Black, Hispanic, Asian/Pacific Islander, and other patients in comparison to White patients. Multivariable regression was performed to identify associations between sociodemographic variables and the primary outcomes. Post-hoc χ2 analyses were performed to compare proportions of patients of a given race/ethnicity across the 3 surgical cohorts. RESULTS: There were 8,809 patients identified in the KID database (mean age of 16.3 years). Compared to White patients, complication rates were increased among Hispanic patients (2.1 vs 1.3%, P = .037) and other patients treated for apnea (8.7 vs 0.83%, P = .002). Hospital LOS was increased in both Black (3.3 vs 2.1 days, P < .001) and Hispanic (2.9 days, P < .001) patients. Costs were higher than Whites ($35,633.47) among Hispanic ($48,029.15, P < .001), Black ($47,034.41, P < .001), and Asian/Pacific-Islander ($44,192.49, P < .001) patients. White patients comprised a larger proportion of the malocclusion group (77.8%) than apnea (66.9%, P < .001) or congenital anomaly (59.1%, P < .001), while the opposite was true for Black, Hispanic, and Asian/Pacific-Islander patients. CONCLUSION: There are significant differences in complications, LOS, and costs after orthognathic surgery among patients of different race/ethnicity. Further studies are needed to better understand the causes of disparity and their clinical manifestations.

BACKGROUND: Dorsal contour irregularities remain a potential undesirable sequela of rhinoplasty. Use of dorsal onlay grafts can camouflage such irregularities. In this article, a novel technique for dorsal onlay grafting utilizing crushed cartilage mixed with autologous fat is described. This study aims to assess long-term graft retention and aesthetic outcomes with this technique. METHODS: Patients with >18-month follow-up who underwent primary open rhinoplasty with the described technique were reviewed. Three-dimensional photographs taken at multiple timepoints were overlaid with volumetric subtraction used to quantify graft retention. The Rhinoplasty module of the FACE-Q was completed by each patient, and the Rhinoplasty Assessment Scale Photographic (RASP) was completed by surgeon reviewers. Pre- and postoperative changes in dorsal height as well as RASP scores were compared with paired t-tests. Changes in BMI, dorsal volume, and dorsal height were compared with linear regression. P values <0.05 were considered significant. RESULTS: Fourteen patients were included, mean age 32. Mean intermediate and final follow-up was 17.8 months and 28.9 months, respectively. There were no statistically significant dorsal height change (mean = 0.0 mm, p = 0.91) and minimal dorsal volume change (mean = 0.02 cm3, range: 0.08 to 0.13). Patients reported a high degree of satisfaction with facial/nasal appearance and psychological/social functioning. There was a statistically significant improvement in RASP scores (p < 0.001) postoperatively. CONCLUSION: Crushed septal cartilage mixed with autologous fat is an effective option for dorsal nasal onlay in rhinoplasty and is associated with excellent graft retention, patient satisfaction, and nasal aesthetics.

BACKGROUND: Rhinoplasty in older adults requires unique consideration of the aging nose. OBJECTIVES: The purpose of this study was to systematically review the literature pertaining to rhinoplasty in the aging population, review the senior author's experience, and describe techniques aimed at addressing age-related features. It was hypothesized that consistent age-related nasal dysmorphology is described in the literature and standard rhinoplasty techniques may effectively address these changes. Furthermore, it was hypothesized that rhinoplasty is more commonly performed for posttraumatic and functional indications than for aesthetic reasons. METHODS: A literature review including publications describing rhinoplasty in patients over 55 years old was conducted. Additionally, a retrospective review of the senior author's cases was performed. Pre- and postoperative photographs were used to compare anthropometric changes. Demographic factors, surgical indications, and operative details were collected. RESULTS: Nine articles met the study criteria. Manifestations of the aging nose included soft tissue atrophy, bony fragility and resorption, tip ptosis, internal and external valve collapse, and worsening dorsal hump. Twenty-seven patients were included in this institutional review. Primary indication for rhinoplasty was posttraumatic deformity in 17 (63%) patients and nasal obstructive symptoms in 10 (37%) patients. Tip refinement and ptosis were addressed through tip grafts (70%), columellar struts (26%), and caudal septal extension grafts (67%). Nasal obstruction was relieved through septoplasty (96%), turbinate ablation (85%), and spreader grafts (70%). CONCLUSIONS: This study presents a systematic review of rhinoplasty in the older adult as well as a retrospective review of the senior author's patients. Unique considerations specific to this population should be integrated into treatment planning.

BACKGROUND: Facial asymmetry from unilateral condylar hyperplasia (UCH) may be definitively treated in the presence of active disease (with high condylectomy and concurrent orthognathic surgery) or after waiting for disease inactivity (orthognathic surgery alone). There is currently no consensus on the standard of care. In this study, we sought to compare functional and esthetic outcomes, as well as treatment duration, between these 2 management options. METHODS: Patients who underwent treatment for UCH were identified through retrospective review. Pre- and postoperative 3-dimensional (3D) images were obtained. Short- and long-term operative outcomes of those treated during the active (group 1) were compared to those treated in the inactive phase (group 2). Total treatment time, operative time, and length of hospital stay were evaluated. Facial asymmetry was also assessed by laypersons using a Likert scale. RESULTS: Fifteen patients (mean 25.6 years, range 14-56) were included: 6 in group 1 and 9 in group 2. All surgical outcomes were statistically independent of procedure type. Treatment time was significantly longer in the group 2 (Pâ=â0.03). Both groups demonstrated significant improvement in facial asymmetry scores postoperatively with no significant difference in pre- or postoperative asymmetry between groups (Pâ=â0.64). CONCLUSIONS: In patients with active UCH, high condylectomy and orthognathic surgery is a procedure that restores facial symmetry and improves jaw function while halting mandibular growth. Good esthetic and functional outcomes, as well as reduced treatment time and disease burden, support the use of this treatment option for this population.

Correction of facial asymmetry caused by active unilateral condylar hyperplasia (CH) requires proper diagnosis, arrested ongoing condylar growth, and ultimately orthognathic surgery. Traditionally, prior to performing orthognathic surgery, active CH is addressed either by: awaiting natural cessation of condylar overgrowth, or performing an interval high condylectomy (to stop growth). However, these strategies both add to the total treatment time, by either waiting and confirming no active growth, or performing a first stage growth-arresting procedure. In this report, the authors describe concurrent high condylectomy, and 3-jaw orthognathic surgery, to address the root of the problem and provide aesthetic correction in the same setting. This clinical series illustrates a detailed description of this approach, highlighting operative order, and an analysis of outcomes.

PURPOSE: Virtual surgical planning (VSP) using computer-aided design and manufacturing (CAD-CAM) has been reported to aid in craniofacial reconstruction. The reported improvements have been related mainly to operative performance, with limited evaluations of the position and function of the temporomandibular joint (TMJ). This study analyzed the radiographic detail of postoperative outcomes related to the TMJ. MATERIALS AND METHODS: Patients who underwent mandibular reconstruction with and without VSP were analyzed. All patients underwent preoperative computed tomography (CT) of their mandible. In the VSP group, CAD-CAM planning was performed preoperatively using CT Digital Imaging and Communications in Medicine (DICOM) data. Postoperative CT images from the 2 groups were quantitatively compared to evaluate the TMJ. CT images were digitized for 2- and 3-dimensional analysis using surgical planning software (Materialise, Leuven, Belgium). Anatomic landmarks and cephalometric relations were analyzed. RESULTS: Sixteen patients who underwent traditional planning or VSP for mandibular reconstruction were compared. Two groups (n = 8 each) were compared for positioning of the mandibular condyle in the glenoid fossa. Measurements of superior, anterior, and lateral movements were comparable in the pre- and postoperative groups for the traditional and VSP groups (P < .001 by analysis of variance). Subgroup analysis evaluating ipsilateral changes in the mandibular condyle position for traditional planning versus VSP noted decreased percentages of change in superior (22 vs 10%; P < .05), anterior (32 vs 15%; P < .05), and lateral (7 vs 1%, P < .01) shifts of the condyle for left mandibular reconstructions (n = 8). Ipsilateral right mandibular reconstructions (n = 6) showed changes in superior (62 vs 15%; P < .05) and anterior (5 vs 9%; not significant) shifts. CONCLUSION: These data showed comparable pre- and postoperative positions of the TMJ for traditional and VSP mandibular reconstructions. Evaluation of condyle movements showed differences in the ipsilateral position in the pre- and postoperative groups. VSP resulted in decreased superior and lateral shifts of the ipsilateral condyle and decreased changes in the condylar and condylar neck angles. This work shows that VSP can lead to increased precision in reconstruction leading to preserved normative anatomic relations.

PURPOSE: Wider cleft palates are thought to be associated with increased complications and poorer outcomes following cleft palate repair. Objective cleft palate photographic measurement and assessment of complications have not been previously performed. The purpose of this study is to quantitatively characterize a series of cleft palate dimensions and to investigate possible correlations with Veau classification and intra-, peri-, and postoperative outcomes. METHODS: The analytic sample included primary cleft palate repairs performed by the senior author over a 2-year period. Standard photographs of clefts taken at the time of repair were analyzed using Image-J software. Demographic, intraoperative, perioperative, and postoperative information were collected. Width measurements were correlated with Veau classification, intraoperative variables, perioperative variables, and adverse outcomes. Statistical tests performed included simple regression analyses and multiple regression analysis. RESULTS: Out of 70 patients, 50 had adequate photographic documentation for inclusion in the study; 44% of patients were classified as Veau I with an average cleft width of 5.4âmm, 28% Veau II with an average of 8.9âmm, 16% Veau III with an average of 11.3âmm, and 12% Veau IV with an average of 10.0âmm. No patients exhibited postoperative bleeding, dehiscence, airway problems, infection, fistula formation, or return to the operating room. The authors found that increasing cleft width significantly predicts increasing Veau classification (Pâ<â0.01), increasing operating time (Pâ<â0.05), increased hypernasality (Pâ<â0.05), and speech delay (Pâ<â0.001). Additionally, the presence of an intentional alveolar fistula (Veau III or Veau IV clefts) significantly predicts fluid emission (Pâ<â0.001) but cleft width did not predict fluid emission. Increased cleft width did not significantly predict length of stay. CONCLUSION: Our data demonstrate that wider preoperative cleft palates correlate with Veau classification, increased operating time, and slightly worsened postoperative sequela. There were no perioperative instances of bleeding, dehiscence, respiratory complications, infection, fistula formation, and return to operating room. Hypernasality and speech delay were associated with increased cleft palate width. Length of stay did not correlate with cleft palate width.
