Geospatial and Socioeconomic Disparities Influencing the Management of Craniosynostosis.

BACKGROUND: Various social determinants of health have been described as predictors of clinical outcomes for the craniosynostosis population. However, literature lacks a granular depiction of socioeconomic factors that impact these outcomes, and little is known about the relationship between patients' proximity to the care center and management of the condition. METHODS/DESIGN: This study retrospectively evaluated patients with craniosynostosis who presented to a tertiary children's hospital between 2000 and 2019. Outcomes of interest included age at presentation for surgery, incidence of reoperation, and length of follow-up. Patient addresses were geocoded and plotted on two separate shapefiles containing block group information within San Diego County. The shapefiles included percent parental educational attainment (bachelor's degree or higher) and median household income from 2010. The year 2010 was chosen for the shapefiles because it is the median year of data collection for this study. Multivariate linear, logistic, and polynomial regression models were used to analyze the relationship between geospatial and socioeconomic predictors and clinical outcomes. RESULTS: There were 574 patients with craniosynostosis included in this study. The mean ± SD Haversine distance from the patient's home coordinates to the hospital coordinates was 107.2 ± 321.2 miles. After adjusting for the suture fused and insurance coverage, there was a significant positive correlation between distance to the hospital and age at index surgery (P = 0.018). There was no correlation between distance and incidence of reoperation (P = 0.266) or distance and duration of follow-up (P = 0.369). Using the same statistical adjustments, lower parental percent educational attainment and lower median household income correlated with older age at index surgery (P = 0.008 and P = 0.0066, respectively) but were not correlated with reoperation (P = 0.986 and P = 0.813, respectively) or duration of follow-up (P = 0.107 and P = 0.984, respectively). CONCLUSIONS: The results offer evidence that living a greater distance from the hospital and socioeconomic disparities including parental education and median household income may serve as barriers to prompt recognition of diagnosis and timely care in this population. However, the geospatial and socioeconomic factors studied do not seem to hinder incidence of reoperation or length of follow-up, suggesting that, once care has been initiated, longitudinal outcomes may be less impacted.

Eyeing Risks: A Critical Analysis of the Use of Periorbital Steroids in Fronto-orbital Advancement.

OBJECTIVE: To evaluate the outcomes associated with two techniques of periorbital steroid administration in bilateral fronto-orbital advancement (FOA). DESIGN: Multi-institutional retrospective chart review. SETTING: Two high volume, tertiary US craniofacial centers. PATIENTS, PARTICIPANTS: Patients who underwent FOA between 2012 and 2021. INTERVENTIONS: Patients were divided into three cohorts based on method of steroid administration. Groups GEL and INJ represent those who received steroids in the form of triamcinolone soaked gelfoam or direct injection of dilute triamcinolone to the frontal/periorbital region, respectively. Group NON did not receive any periorbital steroids. MAIN OUTCOME MEASURE(S): Peri-operative outcomes including hospital length of stay and complications were evaluated based on method of periorbital steroid administration. Variables predictive of infectious complications were assessed using stepwise logistic regression. RESULTS: Four hundred and twelve patients were included in our sample (INJ:249, GEL:87, NON:76). Patients in the INJ group had a higher ASA class (P < .001) while patients in the NON group were significantly more likely to be syndromic (P < .001) and have multisuture craniosynostosis (P < .001). Rate of infectious complications for each cohort were NON: 2.6%, INJ: 4.4%, and GEL: 10.3%. There was no significant difference between groups in hospital length of stay (P = .654) or rate of post-operative infectious complications (P = .061). Increased ASA class (P = .021), increased length of stay (P = .016), and increased intraoperative narcotics (P = .011) were independent predictors of infectious complications. CONCLUSIONS: We identified a dose-dependent relationship between periorbital steroids and rate of postoperative infections, with key contributions from ASA class, hospital length of stay, and dose of intraoperative narcotics.

Long-term aesthetic and photogrammetric outcomes in non-syndromic unicoronal synostosis: comparison of fronto-orbital distraction osteogenesis and fronto-orbital advancement and remodeling.

BACKGROUND: Fronto-orbital advancement and remodeling (FOAR) is among the most common surgical approaches for unicoronal craniosynostosis (UCS), although some data demonstrate failure to achieve long-term aesthetic normalcy, leading some to seek alternative treatment paradigms such as fronto-orbital distraction osteogenesis (FODO). This study compares long-term aesthetic outcomes of patients with UCS treated with FOAR and FODO. METHODS: Twenty patients (four males) with non-syndromic UCS presenting to our institution and undergoing distraction were compared to a matched cohort of 20 patients (six males) undergoing FOAR. Clinical photographs and ImageJ were used to quantify periorbital anatomy including palpebral fissures, pupil-to-brow distance (PTB), and margin-reflex distance (MRD1) in pixels. Whitaker classification was blindly assigned by craniofacial surgeons. RESULTS: Photogrammetric analysis and Mann-Whitney U tests demonstrated significantly improved postoperative symmetry in distraction patients for palpebral width (p = 0.020), MRD1 (p = 0.045), and canthal tilt (p = 0.010). Average Whitaker classification scores between FOAR (1.94) and distraction (1.79) cohorts were similar (p = 0.374). CONCLUSIONS: UCS patients demonstrated significant postoperative improvements in periorbital symmetry, with distraction patients demonstrating superior results in palpebral width and canthal tilt. FOAR and FODO patients achieved similar Whitaker classification scores. These cohorts will be followed until craniofacial maturity prior to making any definitive conclusions.

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.

Spring forces and calvarial thickness predict cephalic index changes following spring-mediated cranioplasty for sagittal craniosynostosis.

BACKGROUND: Variables interacting to predict outcomes following spring-mediated cranioplasty (SMC) for non-syndromic craniosynostosis, including spring parameters and calvarial thickness, are poorly understood. This study assessed interactions between spring parameters and calvarial thickness to predict changes in cephalic index (CI) following SMC. METHODS: Patients undergoing SMC for non-syndromic sagittal craniosynostosis at our institution between 2014 and 2021 were included. Calvarial thickness was determined from patient preoperative CTs using Materalise Mimics at 27 points in relation to the sagittal suture. Linear mixed effects models were used to determine interactions between anterior, middle, and posterior calvarial thickness with spring force and length. RESULTS: Sixty-nine patients undergoing surgery at mean age 3.7 months were included in this study. Stronger posterior spring force interacted with thinner posterior calvarial thickness to predict greater changes in CI at 3 months postoperatively (p = 0.022). When evaluating spring force and calvarial thickness set distances from the sagittal suture, stronger posterior spring force interacted with thinner posterior calvarial thickness 5 mm (p = 0.043) and 10 mm (p = 0.036) from the sagittal suture to predict changes in CI. Interactions between spring parameters and calvarial thickness in the anterior and middle positions did not significantly predict changes in CI. CONCLUSIONS: Stronger posterior spring force interacted with thinner posterior calvaria to predict greater changes in CI 3 months following SMC for non-syndromic sagittal craniosynostosis. These results suggest dynamic interactions between several variables may impact outcomes following SMC.

Real Face Analysis of Masculinity-Femininity, Facial Ratios, and Attractiveness.

BACKGROUND: Previous studies have evaluated the influence of facial features in determining male and female sex using prototypical renderings or artificially altered faces in relatively small sample sizes. Using a large set of human photographs and raters, this study hypothesized that certain anatomic facial ratios are associated with perceptions of masculinity/femininity, can interact to predict sex, and are associated with ratings of attractiveness differently in males and females. METHODS: Ratings of masculinity-femininity and binary self-identification (male or female) were compared with facial anatomic ratios from 827 frontal facial photographs. Ratios were used to characterize facial feature relativity, where higher ratio scores indicated relatively more facial feature representation. RESULTS: Femininity was associated with prominent middle third ratio, nose length, lip vermillion height, eye height, and eye width ratios; masculinity was associated with prominence of the upper and lower facial thirds, nose width, chin height, and philtrum height ratios (all P < 0.01). Subgroup analysis demonstrated many of these relationships persisted when evaluating masculinity in females and femininity in males. Misgendering in males was associated with greater middle third ratio and upper lip ratio, whereas misgendering in females was associated with increased nose width ratio. CONCLUSIONS: This study demonstrates associations of femininity with increased horizontal middle third representation, and masculinity was associated with increased upper and lower horizontal representation. These facial ratios interact to predict male and female sex, which could have implications for optimizing facial feminization/masculinization outcomes and building algorithms for artificial intelligence analysis of faces.

Visual Attention, Bias, and Social Dispositions Toward People With Facial Anomalies: A Prospective Study With Eye-Tracking Technology.

BACKGROUND: Facial attractiveness influences our perceptions of others, with beautiful faces reaping societal rewards and anomalous faces encountering penalties. The purpose of this study was to determine associations of visual attention with bias and social dispositions toward people with facial anomalies. METHODS: Sixty subjects completed tests evaluating implicit bias, explicit bias, and social dispositions before viewing publicly available images of preoperative and postoperative patients with hemifacial microsomia. Eye-tracking was used to register visual fixations. RESULTS: Participants with higher implicit bias scores fixated significantly less on the cheek and ear region preoperatively (P = 0.004). Participants with higher scores in empathic concern and perspective taking fixated more on the forehead and orbit preoperatively (P = 0.045) and nose and lips (P = 0.027) preoperativel. CONCLUSIONS: Participants with higher levels of implicit bias spent less visual attention on anomalous facial anatomy, whereas participants with higher levels of empathic concern and perspective taking spent more visual attention on normal facial anatomy. Levels of bias and social dispositions such as empathy may predict layperson gaze patterns toward those with facial anomalies and provide insights to neural mechanisms underlying the "anomalous is bad" paradigm.

Birk-Barel Intellectual Disability Dimorphism and KCNK9 Imprinting Syndrome: Craniofacial Surgery Considerations for an Exceedingly Rare Syndrome.

Birk-Barel intellectual disability dimorphism syndrome, also referred to as KCNK9 imprinting syndrome, is an exceedingly rare condition described in under 20 cases that presents with intellectual disability, hypotonia, scoliosis, dysphonia, dysphagia, and craniofacial dysmorphic features. The condition follows an autosomal dominant pattern of inheritance in the maternally expressed KCNK9 gene on chromosome 8. Due to the complexity of presentation, patients with Birk-Barel syndrome are optimally managed by a multidisciplinary team including a craniofacial surgeon. Previously described craniofacial dysmorphic features include micrognathia, cleft palate, dolichocephaly, broad nasal tip, and broad philtrum, among others. Here the authors describe a genetically confirmed case that has been managed in our institution's multidisciplinary cleft and craniofacial clinic. The authors aim to discuss Birk-Barel syndrome for a surgical and craniofacial audience with considerations for operative management in the context of a multidisciplinary team.

Machine Learning in Metopic Craniosynostosis: Does Phenotypic Severity Predict Long-Term Esthetic Outcome?

BACKGROUND: There have been few longitudinal studies assessing the effect of preoperative phenotypic severity on long-term esthetic outcomes in metopic craniosynostosis. This study evaluates the relationship between metopic severity and long-term esthetic outcomes using interfrontal angle (IFA) and CranioRate, a novel metopic synostosis severity measure. METHODS: Patients with metopic craniosynostosis who underwent bifrontal orbital advancement and remodeling between 2012 and 2017 were reviewed. Preoperative computed tomography head scans were analyzed for IFA and CranioRate, a machine learning algorithm which generates quantitative severity ratings including metopic severity score (MSS) and cranial morphology deviation (CMD). Long-term esthetic outcomes were assessed by craniofacial surgeons using blinded 3-rater esthetic grading of clinical photos. Raters assessed Whitaker score and the presence of temporal hollowing, lateral orbital retrusion, frontal bone irregularities and/or "any visible irregularities." RESULTS: Preoperative scans were performed at a mean age of 7.7±3.4 months, with average MSS of 6/10, CMD of 200/300, and IFA of 116.8±13.8 degrees. Patients underwent bifrontal orbital advancement and remodeling at mean 9.9±3.1 months. The average time from operation to esthetic assessment was 5.4±1.0 years. Pearson correlation revealed a significant negative correlation between MSS and age at computed tomography ( r =-0.451, P =0.004) and IFA ( r =-0.371, P =0.034) and between IFA and age at surgery ( r =-0.383, P =0.018). In multinomial logistic regression, preoperative MSS was the only independent predictor of visible irregularities (odds ratio=2.18, B =0.780, P =0.024) and preoperative IFA alone significantly predicted Whitaker score, with more acute IFA predicting worse Whitaker score (odds ratio=0.928, B =-0.074, P =0.928). CONCLUSIONS: More severe preoperative phenotypes of metopic craniosynostosis were associated with worse esthetic dysmorphology. Objective measures of preoperative metopic severity predicted long-term esthetic outcomes.

Translation, Validation, and Cultural Adaptation of CLEFT-Q© for use in Indonesia.

OBJECTIVE: To translate and validate CLEFT-Q©, patient-reported outcome measure for patients with cleft lip and/or palate (CL and/or P), into Indonesian. CLEFT-Q© covers the domains of appearance, facial function, health-related quality of life and consists of scales describing outcomes after cleft surgery. DESIGN: The CLEFT-Q© instrument was translated according to the International Society of Pharmacoeconomics and Outcomes Research guidelines, including translation, cognitive debriefing, and field-testing. SETTING: Dr. Cipto Mangunkusumo Hospital, Indonesia; independent CL and/or P support groups. PATIENTS: Patients ages 8-29 with a history of repaired CL and/or P were grouped based on age. Those unable to complete the questionnaire independently were excluded. INTERVENTIONS: The primary objective was reliable translation of the CLEFT-Q® instrument. Each scale was assessed for its internal consistency (Cronbach's alpha) and validity (inter-item correlation), and sub-group analyses were performed based on age group. RESULTS: Forward and back translation revealed 25(13.3%) and 12(6.3%) of items were difficult to translate. Cognitive debriefing revealed 10(5.3%) items were difficult to understand, with the lowest reliability on the facial appearance scale (α=0.27). Other scales demonstrated acceptable to excellent reliability (α=0.53-0.68). Field testing revealed acceptable reliability and validity of the translation (α = 0.74-0.92; 69% ideal range of inter-item correlation). Sub-group analyses revealed patients in the <11y.o. and >18y.o. groups had the lowest scores on the "cleft lip scar" scale while those 11-18y.o. had the lowest scores on the "nostrils" scale. CONCLUSION: Iterative translation and cultural adaptation of CLEFT-Q© into Indonesian demonstrated reliability and validity of the tool, supported by acceptable to excellent internal consistency and ideal inter-item correlation.

Geospatial and Socioeconomic Factors Interact to Predict Management and Outcomes in Cleft Lip and Palate Surgery: A Single Institution Study of 740 Patients.

OBJECTIVE: Determine interactions between geospatial and socioeconomic factors influencing cleft lip and/or cleft palate (CL/P) management and outcomes. DESIGN: Retrospective review and outcomes analysis (n = 740). SETTING: Urban academic tertiary care center. PATIENTS: 740 patients undergoing primary (CL/P) surgery from 2009 to 2019. MAIN OUTCOMES MEASURES: Prenatal evaluation by plastic surgery, nasoalveolar molding, cleft lip adhesion, and age at CL/P surgery. RESULTS: Prenatal evaluation by plastic surgery was predicted by the interaction between higher patient median block group income and shorter patient distance from the care center (OR = 1.07, p = 0.022). Nasoalveolar molding was also predicted by the interaction between higher patient median block group income and shorter distance from the care center (OR = 1.28, p = 0.016), whereas cleft lip adhesion was predicted by higher patient median block group income alone (OR = 0.41, p < 0.001). Lower patient median block group income predicted later age at cleft lip (ß = -67.25, p = 0.011) and cleft palate (ß = -46.35, p = 0.050) repair surgery. CONCLUSIONS: Distance from the care center and lower median income by block group interacted to significantly predict prenatal evaluation by plastic surgery and nasoalveolar molding for patients with CL/P at a large, urban, tertiary care center. Patients living farthest from the care center who received prenatal evaluation by plastic surgery or who underwent nasoalveolar molding had higher median block group income. Future work will determine mechanisms perpetuating these barriers to care.

Speech Outcomes Following Operative Management of Velopharyngeal Dysfunction (VPD) in Non-Syndromic Post-Palatoplasty Cleft Palate Patients.

OBJECTIVE: Approximately 30% of patients with a history of repaired cleft palate (CP) go on to suffer from velopharyngeal dysfunction (VPD). This study discusses the operative management of VPD and postoperative speech outcomes in a cohort of CP patients. SETTING: An academic tertiary pediatric care center. METHODS: Retrospective cohort study. PATIENTS: Patients with history of repaired CP (Veau I-IV) who underwent operative management of VPD between January 1st, 2010 and December 31st, 2020. Operative modalities were posterior pharyngeal flap (PPF), sphincter pharyngoplasty (SPP), Furlow palate re-repair, and buccal myomucosal flap palate lengthening (PL). OUTCOME MEASURES: The primary outcome measure is postoperative speech improvement evaluated by the Pittsburgh Weighted Speech Scale (PWSS). RESULTS: 97 patients met inclusion criteria. 38 patients with previous straight-line primary palatoplasty underwent Furlow re-repair; these patients were significantly younger (7.62 vs 11.14, P < .001) and were more likely to have severe VPD per PWSS (OR 4.28, P < .01, 95% CI 1.46-12.56) when compared to VPD patients with previous Furlow repair. 21.1% of these patients required an additional non-revisional VPD procedure. The remaining patients underwent a non-revision procedure (26 PPF, 22 SPP, 11 PL); all experienced significant (P < .001 on paired t-test) reductions in PWSS total and subgroup VPD severity scores without difference in improvement between operation types. SPP was statistically associated with all-cause complication (OR 2.79, 95% CI 1.03-7.59, P < .05) and hyponasality (OR 3.27, 95% CI 1.112-9.630, P < .05). CONCLUSION: Furlow re-repair reduced need for additional VPD operations. Speech outcomes between non-revisional operations are comparable, but increased complications were seen in SPP.

Disability Caused by Cleft Lip and Palate: A Systematic Review and Critical Valuation Appraisal.

OBJECTIVE: Measuring disability as a concept of impaired global function enables beneficiaries of treatment, the impact of treatment, and targets of health system investment to be rigorously assessed. Measures of disability are not well established for cleft lip and palate. This study aims to systematically review disability weight (DW) studies pertaining to orofacial clefts (OFCs) and identify methodological strengths and shortcomings of each approach. DESIGN: Systematic literature review of studies that met the following criteria: (1) peer-reviewed publication, (2) focus on disability valuation, (3) mention orofacial clefts, and (4) publication January 2001-December 2021. SETTING: None. PATIENTS/PARTICIPANTS: None. INTERVENTIONS: None. MAIN OUTCOME MEASURE(S): Disability weight method of valuation and the value itself. RESULTS: The final search strategy yielded 1,067 studies. Seven manuscripts were ultimately included for data extraction. The disability weights used in our studies, including those newly generated or taken from the Global Burden of Disease Studies (GBD), ranged widely for isolated cleft lip (0.0-0.100) and cleft palate with or without cleft lip (0.0-0.269). The GBD studies limited their consideration of cleft sequelae informing disability weights to impact on appearance and speech-related concerns, while other studies accounted for comorbidities such as pain and social stigma. CONCLUSIONS: Current measures of cleft disability are sparse, inadequately reflect the comprehensive impact of an OFC on function and socialization, and are limited in detail or supporting evidence. Use of a comprehensive health state description in evaluating disability weights offers a realistic means of accurately representing the diverse sequelae of an OFC.

To Operate or Not to Operate? Reconstructive Surgical Burden and Quality of Life of Pediatric Patients with Facial Differences.

OBJECTIVE: The Craniofacial Condition Quality of Life Scale (CFC-QoL) was used to evaluate the relationship between surgical burden and quality of life (QoL). DESIGN: Patient-parent dyads completed the CFC-QoL which queries the following QoL domains: Bullying, Peer Problems, Psychological Impact, Family Support, Appearance Satisfaction, and Desire for Appearance Change. Stepwise multivariate linear regressions were performed for each QoL domain. SETTING: Urban tertiary care center. PATIENTS, PARTICIPANTS: Pediatric patients with facial differences, and their parents. INTERVENTION: Survey study. MAIN OUTCOME MEASURE(S): Demographic, diagnostic, and surgical characteristics were collected. Surgical burden was calculated as the standard deviation from the mean number of surgeries per diagnostic cohort. RESULT: Patients (N = 168) were majority female (57.1%) and Hispanic (64.3%). Diagnoses were cleft lip and/or palate (CLP,n = 99) or other craniofacial conditions (CFC,n = 69). Average patient age was 2.3 ± 5.6 years at first reconstructive surgery and 12.3 ± 3.4 years at study enrollment. Patients received an average of 4.3 ± 4.1 reconstructive surgeries.Worse Bullying was associated with higher surgical burden. Worse Peer Problems was associated with higher surgical burden, but only for children with non-CLP CFCs. Worse Family Support was associated with CFC diagnosis, female sex, and higher surgical burden. Worse Psychological Impact was associated with higher surgical burden. Worse Appearance Satisfaction was associated with younger age and with lower surgical burden. Greater Desire for Appearance Change was associated with older age, higher surgical burden, CLP diagnosis, female sex, and non-Hispanic ethnicity. Socioeconomic status did not predict QoL per patient self- or parent-proxy report. CONCLUSIONS: Higher surgical burden was associated with worse QoL outcomes in multiple domains.

Sociodemographic Disparities in Craniosynostosis: A Systematic Review.

OBJECTIVE: Given the consequences of delayed treatment and diagnosis of craniosynostosis, this study reviews the literature on sociodemographic risk factors and disparities associated with delayed craniosynostosis treatment. DESIGN: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A literature search of PubMed/Medline and Embase was performed by two independent reviewers. Included studies discussed craniosynostosis health disparities. Demographic characteristics and outcomes were analyzed. SETTING: Not applicable. PATIENTS: Patients with craniosynostosis. INTERVENTIONS: Standard surgical intervention for craniosynostosis. RESULTS: Our literature search yielded 273 studies, of which 18 were included for analysis. Included studies represented data from 31 256 U.S. patients with craniosynostosis. Sixty percent of patients (n = 16 510) were White, 13.8% were Hispanic/Latino, 6.2% were Black/African American, 1.3% were Asian, 0.3% were American Indian or Alaska Native, and 0.1% were Native Hawaiian or Pacific Islander. Average age at surgery was 6.36 months for White patients, 10.63 months for Black patients, and 9.18 months for Hispanic patients. Minority racial and/or ethnic status was a risk factor for delayed presentation, and increased incidence of open surgery, complication rates, hospital charges, operative time, anesthesia duration, and hospital length of stay. Government-funded health insurance was associated with delayed intervention and increased complications. CONCLUSIONS: Minority craniosynostosis patients experience delays in intervention and increased complication rates. Our findings highlight the importance of expedited and equitable referrals, screenings, and treatment, and the need for a standardized approach to investigating longitudinal demographic and outcomes data in this population.

Making the Diagnosis in Sagittal Craniosynostosis-It's Height, Not Length, That Matters.

INTRODUCTION: This study assesses the diagnostic reliability of a novel photogrammetric measurement to distinguish sagittal craniosynostosis (SS) from control and false positive cases (SNS). METHODS: Head CTs from 2014-2020 were reviewed for patients with sagittal synostosis (SS, n = 177), presumed sagittal synostosis with normal imaging (SNS, n = 30), and controls (n = 100). Using preoperative clinical photographs and CTs, a measurement reflecting the anterior-posterior location of the vertex was measured using an angle drawn between the cranial vertex, nasion, and opisthocranion (VNO) in profile view, with the head in a neutral position. RESULTS: Mean age at pre-operative head CT was 9.5 months for the SS cohort, 4.2 months for the SNS cohort, and 8.9 months for controls (p = .327). Mean age at pre-operative clinical photograph was 9.5 months for the SS cohort and 4.2 months for the SNS cohort (p = .149). Pearson correlations revealed no significant association between age and VNO angle. The average VNO angle measured on clinical photographs was 54.7° ± 3.8° for the SS group, 43.1° ± 2.2° for the SNS group, and 41.1° ± 3.7° for controls (p < .001). Receiver operating characteristic (ROC) analysis yielded a cut-off of ≥ 50° to identify SS. Diagnostic sensitivity and specificity were 96.6% and 99.2%, respectively. Three-rater analysis yielded an average ICC of 0.742 (p = .004). CONCLUSIONS: Measurement of the VNO angle is a reliable screening tool to diagnose sagittal craniosynostosis, with an angle of 50° or more suggesting suture synostosis. This method relies on the relationship between the anterior displacement of the vertex and occipital bulleting to approach the diagnostic accuracy of CT imaging.

Using the Disruptive Score to Identify Publications That Changed Plastic Surgery Practice.

PURPOSE: The impact of academic publications is often characterized by the total number of future citations. However, this metric does not adequately characterize the true impact in terms of changing practices or paradigms. A new metric called the "disruption score" (DS) has been developed and validated in nonsurgical publications. This study aims to use the DS to identify the most disruptive publications in plastic surgery.The DS, a ratio of 2 numbers, varies between -1 and +1. Scores closer to -1 are developing papers that summarize the known literature while papers closer to +1 are disruptive-they result in a paradigm shift in the field of study. METHODS: A search was performed for all articles from 1954 to 2014 in the following journals: Plastic and Reconstructive Surgery; Aesthetic Surgery Journal; Journal of Plastic, Reconstructive, and Aesthetic Surgery; Annals of Plastic Surgery; Aesthetic Plastic Surgery; Clinics in Plastic Surgery; and Plastic Surgery. The disruptive score was calculated for each article.The top 100 papers ranked by DS were examined and any editorials/viewpoints, publications with less than 26 citations, or less than 3 references were excluded because of their subjective nature and smaller academic contribution. The remaining 64 publications were analyzed for topic, study type, and citation count. RESULTS: A total of 32,622 articles were found with a DS range from 0.385 to 0.923. The mean score of the top 64 articles was 0.539 with an average citation count of 195 and 9 references. Plastic and Reconstructive Surgery had the most disruptive papers with 50. There were no randomized controlled trials with a majority of the studies being technical descriptions or case series. CONCLUSIONS: There are many ways to measure academic success, but there are fewer ways to measure the impact of academic contributions. The DS is a novel measurement that can demonstrate when an article results in a paradigm shift as opposed to just total citation count. When applied to the plastic surgery literature, the DS demonstrates that technical innovation and creativity are the most academically impactful. Future evaluations of academic success should include the DS to measure the quality of academic contributions.

Cadaveric Bone Allografting for Severe Mandibular Hypoplasia With Alleviation of Upper Airway Obstruction in Goldenhar Syndrome.

ABSTRACT: Severe congenital mandibular hypoplasia may cause significant upper airway obstruction, often necessitating immediate tracheostomy. Recent surgical advances have demonstrated early intervention with mandibular distraction osteogenesis over tracheostomy may yield desirable aesthetic and functional outcomes. Here we present a case of bilateral mandibular hypoplasia, severe on the right and mild on the left, secondary to Goldenhar syndrome yielding significant tongue-based upper airway obstruction that was surgically corrected with mandibular bone allograft reconstruction of the right condyle, ramus, and posterior half of the mandibular body. Postoperative polysomnography revealed significantly improved obstructive apnea and computed tomography demonstrated adequate placement of the bone allograft to overcorrect the affected hemi-mandible. To the authors' knowledge, this is the first report of immediate mandibular allografting alleviating tongue-based upper airway obstruction secondary to mandibular hypoplasia in an infant. Mandibular bone allografting may be a favorable alternative to immediate tracheostomy with delayed surgical intervention, though long-term follow up is needed to assess graft durability and maintenance of airway patency.

Lambdoid Craniosynostosis in an Infant With Congenital Cystic Adenomatoid Malformation (CCAM).

ABSTRACT: Both congenital cystic adenomatoid malformation (CCAM) and lambdoid craniosynostosis are exceedingly rare, with estimated incidences of around 1 in 30,000 live births for each. Herein, we present a case of a patient with prenatally diagnosed CCAM requiring 4 doses of prenatal steroids and ultimately thoracotomy with right lower lobectomy. The operation was uncomplicated, and genome-wide analysis of SNPs revealed no pathologic abnormalities. Development was normal until head shape changes were noted at 5 months of age at which point evaluation by a craniofacial surgeon and 3D CT imaging revealed left-sided lambdoid craniosynostosis. The patient underwent uncomplicated posterior and middle vault expansion and remodeling of his lambdoid synostosis at 11 months of age. This paper explores the etiopathogenesis of CCAM and lambdoid craniosynostosis in an attempt to identify common pathways involved in the development of these exceedingly rare diseases which, to date, have not been described in the peer-reviewed literature.

Associations of Facial Proportionality, Attractiveness, and Character Traits.

BACKGROUND: Facial proportionality and symmetry are positively associated with perceived levels of facial attractiveness. OBJECTIVE: The aims of this study were to confirm and extend the association of proportionality with perceived levels of attractiveness and character traits and determine differences in attractiveness and character ratings between "anomalous" and "typical" faces using a large dataset. METHODS: Ratings of 597 unique individuals from the Chicago Face Database were used. A formula was developed as a proxy of relative horizontal proportionality, where a proportionality score of "0" indicated perfect proportionality and more negative scores indicated less proportionality. Faces were categorized as "anomalous" or "typical" by 2 independent reviewers based on physical features. RESULTS: Across the ratings for all faces, Spearman correlations revealed greater proportionality was associated with attractiveness ( ρ = 0.292, P < 0.001) and trustworthiness ( ρ = 0.193, P < 0.001), while lesser proportionality was associated with impressions of anger (ρ = 0.132, P = 0.001), dominance (ρ = 0.259, P < 0.001), and threateningness ( ρ = 0.234, P < 0.001). Mann-Whitney U tests revealed the typical cohort had significantly higher levels of proportionality (-13.98 versus -15.14, P = 0.030) and ratings of attractiveness (3.39 versus 2.99, P < 0.001) and trustworthiness (3.48 versus 3.35, P < 0.001). CONCLUSIONS: This study demonstrated that facial proportionality is not only significantly associated with higher ratings of attractiveness, but also associated with judgements of trustworthiness. Proportionality plays a role in evoking negative attributions of personality characteristics to people with facial anomalies.
