A Novel Macroglossia Severity Index for Beckwith-Wiedemann Syndrome.

OBJECTIVE/ SUMMARY BACKGROUND DATA: We propose the first classification scheme for macroglossia in patients with Beckwith-Wiedemann Syndrome (BWS), the BWS Index of macroGlossia (BIG). METHODS: Patients with molecularly confirmed BWS seen from 2004-2023 were included to develop this system. Relationships among BIG scores, tongue reduction surgery, BWS clinical score, percent mosaicism, and polysomnography findings were examined. RESULTS: Patients were classified from BIG0 to BIG3. BIG0 includes those without macroglossia; BIG1 includes those with macroglossia not protruding beyond the teeth/alveolus; BIG2 includes those with tongue protrusion past the teeth/alveolus to the lips but that can be contained within the mouth; and BIG3 includes those with tongues that protrude beyond the teeth/alveolus and lips but that cannot be closed within the mouth. Of the 459 patients with molecularly confirmed BWS, 266 (58.0%) patients were scored. One hundred and eleven (41.7%) were BIG0, 44 (16.5%) were BIG1, 90 (33.8%) were BIG2, and 21 (7.9%) were BIG3. As scores increased, patients had an increased incidence of tongue reduction surgery (BIG0: 0% versus BIG1: 20.5% versus BIG2: 51.1% versus BIG3: 100%; r=0.66, P <0.01). Higher BIG scores were associated with elevated BWS clinical scores (r=0.68, P <0.01) and increased tissue mosaicism (r=0.50, P <0.01) as well as trends towards worse obstructive apnea-hypopnea indices (r=0.29, P =0.02) and lower SpO 2 nadirs (r=-0.29, P =0.02). CONCLUSION: In this large series of patients with Beckwith-Wiedemann Syndrome, increased BIG score correlates with undergoing tongue reduction surgery and increased phenotypic severity. Adoption of the BIG scoring system may facilitate communication and risk stratification across institutions.

Early posterior vault distraction osteogenesis changes the syndromic craniosynostosis treatment paradigm: long-term outcomes of a 23-year cohort study.

BACKGROUND: Early surgical management of syndromic craniosynostosis varies widely between centers, with patients typically undergoing multiple intracranial procedures through childhood. This study evaluates the long-term impact of early posterior vault distraction osteogenesis (PVDO) versus conventional treatment paradigms on the number and timing of subsequent craniofacial procedures. METHODS: We retrospectively analyzed the longitudinal operative patterns of patients with syndromic craniosynostosis treated from 2000 to 2023 with greater than five years of follow-up. Outcomes of patients who underwent early PVDO and conventional vault reconstruction were compared. RESULTS: Fifty-five patients met the inclusion criteria (30 PVDO and 25 conventional). Age at initial vault surgery was similar between the PVDO and conventional cohorts (7.6 vs. 8.8 months), as were baseline craniometrics (p > 0.05). Multiple fronto-orbital advancement (FOA) procedures were performed in only 1/30 (3%) PVDO-treated patient versus 12/25 (48%) conventionally-treated patients (p < 0.001). Twelve (40%) PVDO-treated patients did not undergo FOA at all. Among patients with Apert and Crouzon syndromes, fewer PVDO-treated patients required FOA prior to midface surgery (33% vs. 92%, p = 0.004) or repeat FOA (6% vs. 50%, p = 0.005) compared to conventionally-treated patients. Among patients with Muenke and Saethre-Chotzen syndromes, a similar proportion of patients required FOA in the PVDO and conventional cohorts (91% vs. 100%, p = 0.353), though no PVDO-treated patients required repeat FOA (0% vs. 44%, p = 0.018). CONCLUSIONS: Early PVDO is associated with a reduction in the high burden of both FOA and, critically, revisionary frontal procedures which are commonly seen in conventionally-treated patients with syndromic craniosynostosis.

Long-term sequelae of normocephalic pansynostosis: a rare but insidious entity.

OBJECTIVE: Patients with normocephalic pansynostosis, who have a grossly normal head shape, are often overlooked early in life and present late with elevated intracranial pressure (ICP) requiring timely cranial vault expansion. This study evaluates the long-term clinical outcomes of patients with normocephalic pansynostosis. METHODS: We retrospectively reviewed patients with a clinical and radiographic diagnosis of primary pansynostosis who underwent vault reconstruction between 2000 and 2023. Clinical and treatment course after craniofacial interventions was followed in patients with normocephaly to assess outcomes. RESULTS: Thirty-five patients with primary pansynostosis were identified, of which eight (23.5%) had normocephaly and underwent initial vault expansion at a mean age of 5.0 ± 2.4 years. All eight patients (50.0% male) presented with symptoms of elevated ICP including headaches (50.0%), nausea and vomiting (50.0%), and developmental delay (62.5%) and/or signs of elevated ICP including papilledema (75.0%) and radiologic thumbprinting on head computed tomography scan (87.5%). Three of the four normocephalic patients who had over 7 years of postoperative follow-up developed subjective headaches, vision changes, or learning and behavioral issues in the long-term despite successful vault reconstruction. CONCLUSIONS: Our longitudinal experience with this rare but insidious entity demonstrates the importance of timely intervention and frequent postoperative monitoring, which are critical to limiting long-term neurological sequelae. Multidisciplinary care by craniofacial surgery, neurosurgery, ophthalmology, and neuropsychology with follow-up into adolescence are recommended to assess for possible recurrence of elevated ICP secondary to cranio-cerebral disproportion.

Vaulting further: cranial vault expansion for craniocerebral disproportion without primary craniosynostosis.

PURPOSE: Treatment of subjects with refractory idiopathic intracranial hypertension (IIH) or shunted hydrocephalus with chronic shunt complications is challenging. What is the role for cranial vault expansion, particularly utilizing posterior vault distraction osteogenesis (PVDO), in these cases? This study assesses medium-term efficacy of cranial vault expansion in this unique patient population. METHODS: A retrospective review was conducted of patients who underwent cranial vault expansion from 2008 to 2023 at the Children's Hospital of Philadelphia. Subjects who did not have a diagnosis of primary craniosynostosis were included in the study. Demographic information, medical history, and perioperative details were collected from medical records. Primary outcomes were the rate of CSF diversion procedures and resolution of presenting signs and symptoms. Secondary outcomes were perioperative and 90-day complications and reoperation requirement. RESULTS: Among 13 included subjects, nine (69.2%) patients had a primary diagnosis of shunted hydrocephalus and 4 (30.8%) patients had IIH. Twelve (92.3%) subjects underwent posterior vault distraction osteogenesis (PVDO) and one (7.7%) underwent posterior vault remodeling (PVR). All 4 patients with IIH demonstrated symptomatic improvement following PVDO, including resolution of headaches, vomiting, and/or papilledema. Among 9 patients with shunted hydrocephalus, CSF diversion requirement decreased from 2.7 ± 1.6 procedures per year preoperatively to 1.2 ± 1.8 per year following cranial vault expansion (p = 0.030). The mean postoperative follow-up was 4.1 ± 2.1 years and four (30.8%) patients experienced complications within 90 days of surgery, including infection (n = 2), CSF leak (n = 1), and elevated ICP requiring lumbar puncture (n = 1). Four (30.8%) patients underwent repeat cranial vault expansion for recurrence of ICP-related symptoms. At most recent follow-up, 7 of 9 patients with shunted hydrocephalus demonstrated symptomatic improvement. CONCLUSION: Cranial vault expansion reduced intracranial hypertension-related symptomology as well as the rate of CSF diversion-related procedures in patients with refractory IIH and shunted hydrocephalus without craniosynostosis, and should be considered in those who have significant shunt morbidity.

Management of Human Bites in a Rural Kenyan Setting: A Plastic Surgeon's 8-Year Experience.

INTRODUCTION: The treatment of human bites is a common issue facing healthcare practitioners in the developing countries of Sub-Saharan Africa where it has been noted as a growing public health concern. Generally, the desired outcomes from surgical management are healing, function, and aesthetics. We share our 8-year experience at Kapsowar Hospital in Kenya with the presentation, management, and outcome of human bites. We are uniquely situated to do so given the prevalence of human biting in our community and the full-time presence of a plastic surgeon at our institution. To the best of our knowledge, this study is the first to present human bite surgical management by a plastic surgeon certified by the American Board of Surgery working full-time on the African continent. METHODS: A retrospective chart review was conducted on all patients who presented to the operating theater at Kapsowar Hospital with a human bite between 2013-2021. After identification of eligible patients, charts were reviewed assessing parameters including age, gender, timing from injury to presentation at hospital, localization of bite, severity of facial wounds using Lackmann's classification, surgical procedure(s), postoperative complications, surgical revisions, antibiotics administered, and circumstance of incident. Data were analyzed using SPSS 29.0.0.0. RESULTS: Forty-four patients were identified. Seventeen (38.6%) were female and 27 (61.4%) were male. Thirty-one patients had facial bites and 13 patients had bites to other parts of the body. Of facial bites, 70.3% resulted in amputation of the affected part while 29.7% were lacerations. Using Lackmann's classification for facial bite severity, IIIA bites (complete avulsion) were most common for both males (9) and females (7). Females comprised 68.4% of total lip bite victims. Bites to the extremity were associated with late presentation and infection. We report a salvage rate of 85.7% for infected digits. CONCLUSIONS: Compared with most other studies on human bites, our patient population presents with a higher rate of avulsive lip injuries, most commonly among women. Our postoperative infection rate is lower than many others reported in the literature. Satisfactory cosmetic outcome with low risk of infection can be achieved by following well-established principles of wound healing and tension-free closure.

Columbia-Suicide Severity Rating Scale (C-SSRS) Reveals High Rates of Suicidality in 602 Patients With Cleft and Craniofacial Conditions.

INTRODUCTION: Little is known about rates of suicidal ideation and behavior among youth with cleft lip and/or palate (CLP) and other craniofacial conditions. METHODS: Records of patients ages 6 and older who were administered the Columbia-Suicide Severity Rating Scale (C-SSRS) Lifetime Version during routine multidisciplinary cleft or craniofacial team visits between 2019 and 2023 were examined. Demographics information, C-SSRS data, and diagnoses were assessed with statistics including t tests, the Fisher exact test, and odds ratios. RESULTS: A total of 1140 C-SSRS questionnaires across 602 (433 CLP and 169 craniofacial) patients with an average age of 11.2±3.7 years were included. Eighty-four (13.6%) patients endorsed lifetime suicidal ideation, 9 (1.5%) had at least one instance of suicidal behavior, 30 (5.0%) endorsed nonsuicidal self-injury, and 2 (0.3%) engaged in self-injurious behavior. Compared with CLP, those with other craniofacial conditions had similar odds of endorsing suicidal ideation and behavior (P≥0.05). Compared with those with isolated cleft palates, CLP had greater odds of endorsing suicidal ideation and behavior, though those differences were not significant (P≥0.05). Incidence of suicidality was unchanged before, during, and after the COVID-19 pandemic (P≥0.05). Dividing patients by sex or insurance type revealed no difference in suicidality (P≥0.05). CONCLUSION: Patients with CLP and craniofacial conditions have a high incidence of suicidal ideation and behavior, though levels are similar between these groups. Suicidality in these patients was not negatively impacted by the COVID-19 pandemic. Early identification of safety risks and psychosocial challenges through regular screening can facilitate connection with appropriate clinical interventions.

Validating the Supraorbital Notch-Nasion-Supraorbital Notch Angle as a Marker for Metopic Craniosynostosis Severity.

OBJECTIVE: Metopic craniosynostosis (MCS) can be difficult to differentiate from metopic ridge (MR) or normal frontal morphology. This study assess whether the supraorbital notch-nasion-supraorbital notch (SNS) angle can help identify MCS. METHODS: Records of 212 patients with preoperative three-dimensional computed tomography scans were examined. The SNS angles, surgeon craniofacial dysmorphology rankings, and CranioRate metopic severity scores (MSSs) were compared with the Spearman rank correlation coefficient. Receiver operating characteristic (ROC) curves with Youden J-statistic and cross-validation of regression models assessed the ability of these measures to predict surgery. RESULTS: A total of 212 patients were included, consisting of 78 MCS, 37 MR, and 97 controls. Both the mean SNS angle (MCS: 111.7 ± 10.7 degrees, MR: 126.0 ± 8.2 degrees, controls: 130.7 ± 8.8 degrees P < 0.001) and MSS (MCS: 5.9 ± 2.0, MR: 1.4 ± 1.9, controls: 0.2 ± 1.9, P < 0.001) were different among the cohorts. The mean SNS angle (111.5 ± 10.7 versus 129.1 ± 8.8, P < 0.001) was lower in those who had surgery and CranioRate score (5.9 ± 2.1 versus 0.8 ± 2.2, P < 0.001) was higher in those who underwent surgery. SNS angles were positively correlated with surgeon craniofacial dysmorphology rankings ( r = 0.41, P < 0.05) and CranioRate MSS ( r = 0.54, P < 0.05). The ROC curve requiring high sensitivity revealed an SNS angle of 124.8 degrees predicted surgery with a sensitivity of 88.7% and a specificity of 71.3%. A ROC curve using the CranioRate MCC values ≥3.19 predicted surgery with 88.7% sensitivity and 94.7% specificity. CONCLUSION: Orbital dysmorphology in patients with MCS is well captured by the supraorbital-nasion angle. Both the SNS angle and CranioRate MSS scores accurately predict surgical intervention.

Nasal Airway Volumes are More Asymmetric in Skeletally Mature Patients With Cleft lip and Palate Than Controls on 3-Dimensional Analysis.

BACKGROUND: This study assesses nasal airway volumes in skeletally mature patients with CLP and healthy controls and examines the relationship among nasal volumes, cleft laterality, and facial asymmetry. METHODS: Computed tomography images from patients with CLP and controls were analyzed using Mimics Version 23.0 (Materialise, Leuven, Belgium). Relationships among nasal airway volume, cleft laterality, and facial asymmetry were compared. RESULTS: The 89 patients in this study included 66 (74%) CLP and 23 (17%) controls. Nasal airway volumes in CLP were more asymmetric than controls (26.8±17.5% vs. 17.2±14.4%; P=0.015). In UCLP, the smaller nasal airway was on the cleft side 81% of the time (P<0.001). Maximum airway stenosis was on the cleft side 79% of the time (P<0.001), and maximum stenosis was on the same side as the smaller airway 89% of the time (P<0.001). There was a mild linear relationship between nasal airway asymmetry and maximum stenosis (r=0.247, P=0.023). On 3-dimensional image reconstruction, the septum often bowed convexly into the cleft-sided nasal airway with a caudal deviation towards the noncleft side. Nasal airway asymmetry was not associated with facial midline asymmetry (P>0.05). CONCLUSION: The nasal airway is more asymmetric in patients with cleft lip and palate compared with the general population, with the area of maximum stenosis usually occurring on the cleft-sided airway. In patients with unilateral cleft lip and palate, the septum often bows into the cleft side, reducing the size of that nasal airway. Nasal airway asymmetry did not correlate with facial asymmetry.

Clinical Research Fellowship Fosters Mentorship, Teamwork, and Productivity: Our 11-Year Experience With a Craniofacial Research Fellowship.

INTRODUCTION: This study describes the development and explores the academic impact of a cleft and craniofacial research fellowship. MATERIALS AND METHODS: Research and career outcomes from 3 cleft and craniofacial surgeons, 14 clinical fellows, and 25 research fellows between 2010 and 2023 were examined. Academic productivity was measured by the number of peer-reviewed publications indexed in PubMed and podium presentations at national/international meetings. Residency match statistics were recorded for eligible research fellows. RESULTS: Over this 14-year period (11 with research fellows), the team produced 500 publications in 96 peer-reviewed journals, with 153 (31%) in Plastic and Reconstructive Surgery, 117 (23%) in the Journal of Craniofacial Surgery, and 32 (6%) in The Cleft Palate-Craniofacial Journal. Yearly publications increased from 15.3±7.6 per year (before fellowship) to 23.0±5.3 (with 1 fellow) to 38.3±12.9 (2 fellows) to 81.0±5.7 (3 fellows; P<0.001). There was a strong annual linear growth in publications since the beginning the research fellowship position (r=0.88, P<0.001). All (100%) clinical research fellows developed strong relationships with senior surgeons, and all who applied to plastic surgery residency matched a significantly higher success rate than the national average (P<0.05). CONCLUSION: Implementing a structured cleft and craniofacial clinical research fellowship was associated with a broad impact across all cleft and craniofacial team members, as reflected by increased academic output and high match rates among fellows. The fellowship also strengthens the talent pipeline into plastic surgery by fostering meaningful mentor/mentee relationships and provides a model that can be adopted in both surgical and nonsurgical fields.

Crowdsourcing the Impact of Illustration in Cleft Surgery Education.

OBJECTIVE: This study aimed to (1) assess layperson preferences for how surgical information is presented; (2) evaluate how the format of visual information relates to layperson comfort with undergoing surgery, perceptions of surgeon character traits, and beliefs about artistic skill impacting plastic surgery practice; and (3) identify sociodemographic characteristics associated with these outcomes. DESIGN: A survey was developed in which one of five standardized sets of information depicting a unilateral cleft lip repair was presented as (1) text alone, (2) quick sketches, (3) simple drawings, (4) detailed illustrations, or (5) photographs. SETTING: Online crowdsourcing platform. PARTICIPANTS: Raters aged 18 years and older from the United States. INTERVENTIONS: None. MAIN OUTCOME MEASURE(S): After viewing the surgical information, participants answered three sets of Likert scale questions. Ratings were averaged to produce three composite scores assessing (1) comfort with undergoing surgery (2) perceptions of surgeon character traits, and (3) beliefs about plastic surgery and artistry. RESULTS: Four hundred seventy-nine participants were included. Surgeon character traits score was highest among participants who viewed detailed illustrations at 4.46 ± 0.59, followed by photographs at 4.43 ± 0.54, text alone at 4.28 ± 0.59, simple drawings at 4.17 ± 0.67, and quick sketches at 4.17 ± 0.71 (p = 0.0014). Participants who viewed detailed illustrations rated surgical comfort score and plastic surgery and artistry score highest, although differences did not achieve statistical significance. CONCLUSIONS: Viewing detailed cleft lip repair illustrations was significantly associated with positive perceptions of surgeon character traits. Our data help to contextualize methods of communication and education valued by the public when seeking cleft care.

Psychosocial Status and Self-Perception in Patients with Cleft Lip and/or Palate.

OBJECTIVE: To describe how the psychosocial status of patients with cleft lip and/or palate (CL/P) relates to patient-reported outcomes (PROs). DESIGN: Cross-sectional retrospective chart review. SETTING: Tertiary care pediatric hospital. PATIENTS/PARTICIPANTS: Patients aged 8 to 29 years attending cleft team evaluations during a 1-year period. MAIN OUTCOME MEASURES: CLEFT-Q. RESULTS: Patients (N = 158) with isolated or syndromic CL/P and mean age 13.4 ± 3.0 years were included. Fifteen (9%) patients had siblings who also had CL/P. Of 104 patients who met with the team psychologist, psychosocial concerns were identified in 49 (47%) patients, including 25 (24%) with Attention-Deficit/Hyperactivity Disorder or behavior concerns, 28 (27%) with anxiety, and 14 (13%) with depression or mood concerns. Younger age and having siblings with cleft were associated with better PROs, while psychosocial concerns were associated with worse PROs on Speech, Psychosocial, and Face Appearance scales. CONCLUSIONS: Patient perception of cleft outcomes is linked to psychosocial factors.

Spinal pseudomeningocele closure: capsulofascial interposition technique.

INTRODUCTION: The development of a spinal pseudomeningocele is a complication of dural repair or reconstruction that carries significant morbidity for pediatric patients. In addition to cerebrospinal fluid (CSF) hypotension and positional headaches, CSF leaking into the extradural space increases the risk for incisional breakdown, meningitis, and cosmetic deformity. Spinal pseudomeningocele management is challenging, and reported techniques range from local wound revisions/exploration to shunt placement for permanent CSF diversion. METHODS: At our institution, we have recently implemented a multidisciplinary approach of capsulofascial interposition for the surgical repair of the symptomatic spinal pseudomeningocele with a combined neurosurgery-plastic surgery team. To our knowledge, this technique has not previously been characterized, and we describe the technical aspects of this surgery here. RESULTS: Among 10 patients treated with this technique, none required reoperation or developed infections following pseudomeningocele closure; 2 patients received postoperative transfusions; and 2 patients underwent CSF diversion procedures. CONCLUSION: We propose that this capsulofascial interposition technique should be employed in the surgical treatment of symptomatic spinal pseudomeningoceles.

Clinical practice guidelines for management of head and neck squamous cell carcinoma of unknown primary: an AGREE II appraisal.

IMPORTANCE: Squamous cell carcinoma without a known primary is an uncommon form of head and neck cancer that requires multidisciplinary collaboration for effective management. OBJECTIVE: To evaluate the quality of clinical practice guidelines (CPG) using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. DESIGN: A systematic literature search was performed to identify CPGs pertaining to the diagnosis and treatment of head and neck squamous cell carcinoma of unknown primary (HNSCCUP). Data were abstracted from guidelines meeting inclusion criteria and appraised by four independent reviewers in the six domains of quality defined by the AGREE II. SETTING: Online database. PARTICIPANTS: None. EXPOSURE: None. MAIN OUTCOME(S) AND MEASURE(S): Quality domain scores and intraclass correlation coefficients (ICC) were calculated across domains to qualify inter-rater reliability. RESULTS: Seven guidelines met inclusion criteria. Two guidelines achieved a score of > 60% in five or more AGREE II quality domains to gain designation as 'high'-quality content. One "average-quality" guideline authored by the ENT UK Head and Neck Society Council achieved a score of > 60% in three quality domains. The remaining four CPGs demonstrated low-quality content, with deficits most pronounced in domains 3 and 5, suggesting a lack of rigorously developed and clinically applicable information. CONCLUSIONS AND RELEVANCE: As the diagnosis and treatment of head and neck cancer continues to evolve, identification of high-quality guidelines will become increasingly important. The authors recommend consulting HNSCCUP guidelines from the National Institute for Health and Care Excellence (NICE) or the American Society of Clinical Oncology (ASCO). TRIAL REGISTRATION: None.

Delayed Postnatal Synostosis without Spheno-occipital Synchondrosis Fusion: A Curious Case of Apert Syndrome.

Apert syndrome classically presents with craniosynostosis at birth, most commonly of the bilateral coronal sutures, which may lead to cephalocranial disproportion and elevated intracranial pressure, the latter of which is associated with optic atrophy, visual loss, and developmental delays. A small number of patients with syndromic craniosynostosis demonstrate open sutures at birth; however, all previously reported patients of this subtype have been reported to develop premature suture fusion in the early postnatal period and/or require cranial vault expansion for increased intracranial pressure. Here, we report on a patient with Apert syndrome who did not have closed sutures at birth, and only began to demonstrate unilateral coronal suture fusion between ages 4 and 6 years, yet neither developed phenotypic signs of craniosynostosis nor evidence of intracranial hypertension. Moreover, despite demonstrating patency of the spheno-occipital synchondrosis, the patient developed progressive midface hypoplasia, requiring a subcranial Le Fort 3 advancement with external distraction at age 9. Now at skeletal maturity, this patient has a normal cranial shape and will likely never require cranial vault surgery for functional or aesthetic concerns. We are not aware of any prior reports of a patient with Apert syndrome who did not require intracranial surgery over long-term follow-up.

The Expanded Forehead Flap for Resurfacing of Multi-unit Congenital Nevi of the Face.

The forehead flap is a timeless and robust reconstructive option for complex facial defects. In accordance with aesthetic subunit principles, it has traditionally been used to resurface defects affecting a single cervicofacial region, most commonly the nose or periorbital unit. In this article, we present three cases of congenital nevi treated with expanded forehead flap reconstruction of the nasal, periorbital, and cheek units in early childhood. This series demonstrates an approach that, while violating facial units, limits total scar burden and optimizes aesthetic and functional results. With precise staging and execution, this reconstructive technique allows for a single flap to resurface multi-unit defects in the pediatric population with excellent long-term results.

The Kaleidoscope of Midface Management in Apert Syndrome: A 23-Year Single-Institution Experience.

BACKGROUND: This study assesses operative trends over time and outcomes of five osteotomy techniques used to treat the Apert midface. Using clinical and photogrammetric data, we present our institution's selection rationale for correcting specific dysmorphologies of the Apert midface based on the individual phenotype. METHODS: We retrospectively reviewed patients with Apert syndrome who underwent midface distraction from 2000 to 2023. Patients were temporally divided by the year 2012 to assess differences in surgical approach. Postoperative facial dimension changes, surgical and perioperative characteristics, and complications data were compared across techniques. RESULTS: Thirty-nine patients with Apert syndrome underwent 41 midface distraction procedures: 23 (56%) in the early cohort and 18 (44%) in the late cohort. The use of segmental osteotomies for frontofacial advancement increased from 0% before 2012 to 61% from 2012 onwards (p<0.001). Monobloc with bipartition was the only technique that decreased intercanthal distance (p=0.016), and Le Fort II with zygomatic repositioning achieved the greatest median change in bilateral canthal tilt of 8.7° (IQR 1.3°, 8.7°; p=0.068). Monobloc with Le Fort II achieved the greatest median change in facial convexity of -34.9° (IQR -43.3°, -29.2°; p=0.031). Severity of complications, stratified by Clavien-Dindo grade, was greater in transcranial than subcranial procedures but similar between segmental and non-segmental osteotomies (p=0.365). CONCLUSIONS: In studying the Apert midface and attempting to resolve its varying functional and aesthetic issues, we document an evolution towards multi-piece osteotomies over time. With an appreciation for differential midface hypoplasia, segmentation is associated with more effective normalization of the Apert face.

Autologous Cranioplasty Using a Dental SafeScraper Device.

SUMMARY: Conventional methods to reconstruct cortical bone defects introduced by pediatric cranial vault remodeling (CVR) procedures have shortcomings. Use of bone burr shavings as graft material leads to variable ossification, and harvesting split-thickness cortical grafts is time-intensive and often not possible in thin infant calvaria. Since 2013, the authors' team has used the SafeScraper, originally developed as a dental instrument, to harvest cortical and cancellous bone grafts during CVR. The authors assessed the effectiveness of this technique by analyzing postoperative ossification using computed tomography scans of 52 patients, comparing cohorts treated with the SafeScraper versus those who received conventional methods of cranioplasty during fronto-orbital advancement. The SafeScraper cohort had a greater reduction in total surface area of all defects (-83.1% ± 14.9 versus -68.9% ± 29.8; P = 0.034), demonstrating a greater and more consistent degree of cranial defect ossification compared with conventional methods of cranioplasty, suggesting potential adaptability of this tool. This is the first study that describes the technique and efficacy of the SafeScraper in reducing cranial defects in CVR. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Mandibular condyle volumes are associated with facial asymmetry in patients with cleft lip and palate: A retrospective cohort study.

This study compares condylar volumetric asymmetry and facial asymmetry in patients with cleft lip and/or palate (CLP) and controls. The mandibular condyle is important to facial growth, but its role in facial asymmetry for those with CLP has not been described. Condylar volumes and mandibular asymmetry were retrospectively calculated using Mimics Version 23.0 (Materialise, Leuven, Belgium) from patients with CLP undergoing computed tomography (CT) imaging and a cohort of controls. A total of 101 participants, 60 with CLP and 41 controls, had mean condylar volumetric asymmetry of 16.4 ± 17.4 % (CLP) and 6.0 ± 4.0 % (controls) (p = 0.0002). Patients with CLP who had clinically significant chin deviation (>4 mm) had more asymmetric condyles than those without significant chin deviation (p = 0.003). The chin deviated toward the smaller condyle in patients with facial asymmetry more often than in patients without facial asymmetry (81 % vs. 62 %, p = 0.033). While controls had some degree of condylar asymmetry, it tended to be milder and not associated with facial asymmetry. There is a greater degree of condylar volumetric asymmetry in patients with CLP compared to individuals in the general population. Clinically significant facial asymmetry in CLP is associated with a higher degree of condylar asymmetry, with the facial midline deviating toward the smaller condyle.

Periorbital Outcomes and Vision Risk Stratification in Treacher Collins Syndrome.

BACKGROUND: We examined ophthalmologic outcomes and periorbital management in patients with Treacher Collins syndrome (TCS). METHODS: A retrospective cohort study was performed of children with TCS treated from 2009 to 2023 at our center. Demographics and medical history were collected. Primary outcomes were periorbital findings, surgical burden, and visual acuity. Patients were stratified by risk of vision loss based on ophthalmologic findings. RESULTS: Among 50 subjects, mean follow-up was 10.5±5.9 years. Periorbital findings included downslanting palpebral fissures (100%), eyelash deficiency (70%), eyelid coloboma (54%), and significant refractive error (50%). Twenty (40%) individuals underwent 86 periorbital procedures, including lateral canthopexy (n=23 operations) and malar/zygomatic reconstruction/augmentation (n=20). Lateral canthopexies accompanied by malar fat grafting were less likely to require reoperation (0% versus 72%, p=0.004). Subjects with eyelid coloboma were more likely to have exposure keratopathy (30% versus 4%, p=0.020). Grouped by risk of vision loss, 58% were "High" risk, 18% were "Moderate", and 24% were "Low". Among 78 eyes of 39 subjects, vision was "Good" in 90%, "Fair" in 5%, and "Poor" in 6%. Vision risk grading was associated with visual acuity outcomes (n=29) (p=0.050). CONCLUSIONS: In assessing long-term ophthalmological outcomes, we noted good vision despite significant periorbital anomalies. Though most eyelid colobomas can be managed with lubrication, those threatening corneal integrity should be repaired in infancy. As timely intervention may prevent visual impairment, we recommend perinatal ophthalmologist evaluation for all children with TCS. Our proposed vision risk scale may serve as a helpful paradigm by which to contemplate vision-related issues.

Trends in Blood Mosaicism and Clinical Phenotype Score in Patients with Beckwith-Wiedemann Syndrome Evaluated for Tongue Reduction Surgery.

INTRODUCTION: Most patients with Beckwith-Wiedemann syndrome (BWS) have macroglossia with some requiring tongue reduction surgery (TRS). This study reports correlations between levels of affected cells (mosaicism) and BWS clinical score in patients evaluated for TRS. We also show correlations of clinical score and mosaicism with obstructive sleep apnea (OSA) severity. METHODS: Blood mosaicism levels and BWS clinical score were recorded in patients with macroglossia referred to plastic surgery for evaluation. Associations among blood mosaicism, BWS clinical score, TRS, and OSA were assessed with appropriate statistics. RESULTS: Of the 225 patients included, BWS blood testing was available in 128 (56.9%). Mosaicism levels were higher in those who underwent TRS compared to those who did not (85.9 85.9 (56.5-95.9)% vs. 29.7 (2.8-73.1)%, p<0.001). BWS clinical score was also higher in those requiring TRS (9.0 (8.0-11.0) versus 7.0 (6.0-9.0), p<0.001). There was a positive correlation between clinical score and obstructive apnea-hypopnea index (r=0.320, p=0.011). Receiver operating characteristic curve analysis showed a clinical score ≥11 had 100% specificity and 36.4% sensitivity for detecting patients requiring TRS. Blood mosaicism ≥80% had 63.6% sensitivity and 83.6% specificity for predicting surgery. A combined criteria of BWS clinical score ≥11 or mosaicism ≥80% had 72.7% sensitivity and 83.6% specificity for predicting TRS. CONCLUSION: Blood mosaicism levels and higher BWS clinical scores appear associated with a greater frequency of having surgery in patients with macroglossia referred for surgical evaluation. Elevations in BWS clinical scoring are associated with increased OSA severity while increased blood mosaicism is not.
