- Abstract
Traumatic brain injury (TBI) is common in up to 50% of patients with facial fractures. Orbital fractures account for 25% of all facial fractures. The authors sought to determine the prevalence and risk factors for TBI in patients undergoing orbital fracture repair (OFR) and assess the impact of TBI on surgical timing. A retrospective review of trauma patients who underwent OFR at a single trauma center from 2015 to 2020 was conducted. Excluded were patients <18 years old and those with unreported GCS on presentation. TBI was defined as GCS <15 or any neurological symptom on presentation. TBI was categorized into mild (GCS=14-15), moderate (GCS=9-13), and severe TBI (GCS=3-8). Our primary and secondary outcomes were the prevalence of TBI on presentation and duration from injury to surgery, respectively. Of the 200 patients analyzed, 99 (49.5%) had concomitant TBI on presentation. The most common neurological symptom on presentation was loss of consciousness [n=80 (40%)]. Patients with TBI were significantly more likely to have an orbital roof [n=11 (11.1%), n=4 (4.0%), P=0.048] and lateral wall fractures [n=25 (25.3%), n=14 (13.9%), P=0.031] compared with patients without TBI. Patients with severe TBI were more likely to have delayed OFR-a significantly greater proportion of patients who had severe TBI had OFR after 60 days of injury compared with those without TBI or with mild TBI [5 (39%), 12 (12%), 4 (5%), P=0.032]. Craniofacial surgeons must suspect and screen for TBI in patients presenting with facial trauma, especially those with orbital roof and lateral wall fractures., Competing Interests: The authors report no conflicts of interest, (Copyright © 2024 by Mutaz B.

- Abstract
Facial buttresses are supportive bony structures of the facial skeleton that form a thick, strong, and protective framework for the face. Surgical fixation may be required to restore morphology and function when damage to these buttresses occurs. We sought to determine if, similar to buttresses of the facial skeleton, buttresses of the internal orbit exist. Hence, we analyzed 10 human cadaver skulls imaged by microcomputed tomography (micro-CT). Image processing and thickness/heat mapping were performed using Avizo and ImageJ softwares. After identifying the orbital buttresses, we reviewed CT scans of patients who had orbital fractures across three years to determine the frequency of fracture of the orbital buttresses. We identified 5 buttresses of the internal orbit: superomedial fronto-ethmoidal strut with the deep orbital buttress, inferomedial strut with the posterior ledge, inferior orbital fissure, sphenoid-frontal superolateral strut, and the sphenoid lip. The average threshold orbital buttress thickness was 1.36 (0.25) mm. A total of 1186 orbits of 593 individuals were analyzed for orbital buttress involvement. Orbital buttresses were spared in 770 (65%) orbits. The inferomedial strut with the posterior ledge was the most commonly fractured buttress in 14.4% of orbits (n=171), followed by the sphenoid strut and lip (66 [5.6%]). To our knowledge, this is the first description of the buttresses of the internal orbit. Orbital reconstruction for fracture repair or oncologic purposes requires the support of orbital buttresses. Understanding the anatomy of orbital buttresses is crucial for successful surgical planning, proper implant positioning, and restoration of function and appearance., Competing Interests: Financial Disclosure Statement: All authors report no potential conflicts of interest, including financial interests, activities, relationships, and affiliations.

- Abstract
Traumatic optic neuropathy (TON) is a rare but potentially devastating complication of craniofacial trauma. Approximately half of patients with TON sustain permanent vision loss. In this study, we sought to identify the most common fracture patterns associated with TON. We performed a retrospective review of craniomaxillofacial CT scans of trauma patients who presented to the R Adams Cowley Shock Trauma Center from 2015 to 2017. Included were adult patients who had orbital fractures with or without other facial fractures. Patients diagnosed with TON by a formal ophthalmologic examination were analyzed. Craniofacial fracture patterns were identified. Bivariate analysis and multivariate logistic regression were performed to identify craniofacial fracture patterns most commonly associated with TON. A total of 574 patients with orbital fractures who met inclusion criteria [15 (2.6%)] were diagnosed with TON. The median [interquartile range (IQR)] age was 44 (28-59) years. Patients with optic canal fractures and sphenoid sinus fractures had greater odds of TON compared with patients who did not have these fracture types [adjusted odds ratio (aOR) 95% confidence interval (CI) 31.8 (2.6->100), 8.1 (2.7-24.4), respectively]. Patients who sustain optic canal and sphenoid sinus fractures in the setting of blunt facial trauma are at increased odds of having a TON. Surgeons and other physicians involved in the care of these patients should be aware of this association., Competing Interests: The authors report no conflicts of interest., (Copyright © 2024 by Mutaz B.

- Abstract
Postoperative diplopia is the most common complication following orbital fracture repair (OFR). Existing evidence on its risk factors is based on single-institution studies and small sample sizes. Our study is the first multi-center study to develop and validate a risk calculator for the prediction of postoperative diplopia following OFR. We reviewed trauma patients who underwent OFR at two high-volume trauma centers (2015-2019). Excluded were patients < 18 years old and those with postoperative follow-up < 2 weeks. Our primary outcome was incidence/persistence of postoperative diplopia at ≥ 2 weeks. A risk model for the prediction of postoperative diplopia was derived using a development dataset (70% of population) and validated using a validation dataset (remaining 30%). The C-statistic and Hosmer-Lemeshow tests were used to assess the risk model accuracy. A total of n = 254 adults were analyzed. The factors that predicted postoperative diplopia were: age at injury, preoperative enophthalmos, fracture size/displacement, surgical timing, globe/soft tissue repair, and medial wall involvement. Our predictive model had excellent discrimination (C-statistic = 80.4%), calibration (P = 0.2), and validation (C-statistic = 80%). Our model rules out postoperative diplopia with a 100% sensitivity and negative predictive value (NPV) for a probability < 8.9%. Our predictive model rules out postoperative diplopia with an 87.9% sensitivity and a 95.8% NPV for a probability < 13.4%. We designed the first validated risk calculator that can be used as a powerful screening tool to rule out postoperative diplopia following OFR in adults., (© 2024. The Author(s).)

- Abstract
Study Design: Retrospective chart review of revisional orbital surgery outcomes in patients with diplopia from prior operative treatment of orbital trauma., Objective: Our study seeks to review our experience with management of persistent post-traumatic diplopia in patients with previous orbital reconstruction and present a novel patient stratification algorithm predictive of improved outcomes., Methods: A retrospective chart review was performed on adult patients at Wilmer Eye Institute at Johns Hopkins Hospital and at the University of Maryland Medical Center who underwent revisional orbital surgery for correction of diplopia for the years 2005-2020. Restrictive strabismus was determined by Lancaster red-green testing coupled with computed tomography and/or forced duction. Globe position was assessed by computed tomography. Seventeen patients requiring operative intervention according to study criteria were identified., Results: Globe malposition affected fourteen patients and restrictive strabismus affected eleven patients. In this select group, improvement in diplopia occurred in 85.7% of cases with globe malposition and in 90.1% of cases with restrictive strabismus. One patient underwent additional strabismus surgery subsequent to orbital repair., Conclusions: Post-traumatic diplopia in patients with prior orbital reconstruction can be successfully managed in appropriate patients with a high degree of success. Indications for surgical management include (1) globe malposition and (2) restrictive strabismus. High resolution computer tomography and Lancaster red-green testing discriminate these from other causes that are unlikely to benefit from orbital surgery., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

- Abstract
Background: Mandibular fractures are the most common of pediatric facial fractures. The effect of race on management/outcomes in these injuries has not been previously studied. Given the significant association between race and healthcare outcomes in many other pediatric conditions, an in-depth study of race as related to mandibular fractures in the pediatric patient population is warranted., Methods: This was a 30-year retrospective, longitudinal study of pediatric patients who presented to a single institution with mandibular fractures. Patient data were compared between patients of different races and ethnicities. Demographic variables, injury characteristics, and treatment variables were analyzed to find predictors of surgical treatment and posttreatment complications., Results: One hundred ninety-six patients met inclusion criteria, of whom 49.5% were White, 43.9% were Black, 0.0% were Asian, and 6.6% were classified as "other." Black and "other" patients were more likely than their White counterparts to be injured as pedestrians (P = 0.0005). Black patients were also more likely than White patients or "other" patients to be injured by assault than by sports-related injuries or animal-related accidents (P = 0.0004 and P = 0.0018, respectively). Race or ethnicity were not found to be a predictor of receiving surgical treatment (ORIF) or of posttreatment complications. The posttreatment rates for all the complications observed were comparable among all race and ethnic groups. Higher mandible injury severity score (odds ratio [OR], 1.25), condyle fracture (OR, 2.58), and symphysis fracture (OR, 3.20) were positively correlated with receiving ORIF as treatment. Mandible body fracture (OR, 0.36), parasymphyseal fracture (OR, 0.34), bilateral mandible fracture (OR, 0.48), and multiple mandibular fractures (OR, 0.34) were negatively correlated with receiving ORIF as treatment. Only high mandible injury severity score (OR, 1.10) was identified as an independent predictor of posttreatment complications. Lastly, Maryland's transition to an all-payer model in 2014 also had no impact on treatment modality; treatment of fractures among race and ethnicity were not significantly different pre- and post-2014., Conclusions: There is no difference in how patients are treated (surgically vs nonsurgically) and no difference in outcomes for patients based on race at our institution. This could be due to institutional ideology, services provided by a tertiary care center, or simply the more diverse patient population at baseline., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2023 Wolters Kluwer Health, Inc.

- Abstract
Background: Despite clinical concerns associated with pediatric traumatic brain injuries (TBIs), they remain grossly underreported. This is the first retrospective study to characterize concomitant pediatric TBIs and craniomaxillofacial (CMF) trauma patients, including frequency, presentation, documentation, and outcomes., Methods: An institutional review board-approved retrospective cohort study was performed to identify all pediatric patients presenting with CMF fractures at a high-volume, tertiary trauma center between the years 1990 and 2010. Patient charts were reviewed for demographic information, presentation, operative management, length of stay, mortality at 2 years, dentition, CMF fracture patterns, and concomitant TBIs. Data were analyzed using two-tailed t tests and chi-square analysis. A value of P≤ 0.05 was considered statistically significant., Results: Of the 2966 pediatric CMF trauma patients identified and included for analysis [mean age, 7 ± 4.7 years; predominantly White (59.8%), and predominantly male (64.0%)], 809 had concomitant TBI (frequency, 27.3%). Only 1.6% of the TBI cases were documented in charts. Mortality at 2 years, length of stay in the hospital, and time to follow-up increased significantly from mild to severe TBIs. Concomitant TBIs were more common with skull and upper third fractures than CMF trauma without TBIs (81.8% versus 61.1%; P < 0.05)., Conclusions: Concomitant TBIs were present in a significant number of pediatric CMF trauma cases but were not documented for most cases. CMF surgeons should survey all pediatric CMF trauma patients for TBI and manage with neurology and/or neurosurgery teams. Future prospective studies are necessary to characterize and generate practice-guiding recommendations., Clinical Question/level of Evidence: Risk, II., Competing Interests: Disclosure:The authors have no financial interests or conflicts of interest to declare ., (Copyright © 2022 by the American Society of Plastic Surgeons.)

- Abstract
Background: In 2014, the Plastic Surgery Residency Review Committee of the Accreditation Council for Graduate Medical Education (ACGME) increased minimum aesthetic surgery requirements. Consequently, the resident aesthetic clinic (RAC) has become an ever more important modality for training plastic surgery residents., Objectives: To analyze demographics and long-term surgical outcomes of aesthetic procedures performed at the Johns Hopkins and University of Maryland (JH/UM) RAC. A secondary objective was to evaluate the JH/UM RAC outcomes against those of peer RACs as well as board-certified plastic surgeons., Methods: We performed a retrospective chart review of all patients who underwent aesthetic procedures at the JH/UM RAC between 2011 and 2020. Clinical characteristics, minor complication rates, major complication rates, and revision rates from the JH/UM RAC were compared against 2 peer RACs. We compared the incidence of major complications between the JH/UM RAC and a cohort of patients from the CosmetAssure (Birmingham, AL) database. Pearson's chi-square test was used to compare complication rates between patient populations, with a significance set at 0.05., Results: Four hundred ninety-five procedures were performed on 285 patients. The major complications rate was 1.0% (n = 5). Peer RACs had total major complication rates of 0.2% and 1.7% ( P = .07 and P = .47, respectively). CosmetAssure patients matched to JH/UM RAC patients were found to have comparable total major complications rates of 1.8% vs 0.6% ( P = .06), respectively. At JH/UM, the minor complication rate was 13.9%, while the revision rate was 5.9%., Conclusions: The JH/UM RAC provides residents the education and training necessary to produce surgical outcomes comparable to peer RACs as well as board-certified plastic surgeons., (© The Author(s) 2022.

- Abstract
Background: Cranioplasty is critical to cerebral protection and restoring intracranial physiology, yet this procedure is fraught with a high risk of complications. The field of neuroplastic surgery was created to improve skull and scalp reconstruction outcomes in adult neurosurgical patients, with the hypothesis that a multidisciplinary team approach could help decrease complications., Objective: To determine outcomes from a cohort of cranioplasty surgeries performed by a neuroplastic surgery team using a consistent surgical technique and approach., Methods: The authors reviewed 500 consecutive adult neuroplastic surgery cranioplasties that were performed between January 2012 and September 2020. Data were abstracted from a prospectively maintained database. Univariate analysis was performed to determine association between demographic, medical, and surgical factors and odds of revision surgery., Results: Patients were followed for an average of 24 months. Overall, there was a reoperation rate of 15.2% (n = 76), with the most frequent complications being infection (7.8%, n = 39), epidural hematoma (2.2%, n = 11), and wound dehiscence (1.8%, n = 9). New onset seizures occurred in 6 (1.2%) patients.Several variables were associated with increased odds of revision surgery, including lower body mass ratio, 2 or more cranial surgeries, presence of hydrocephalus shunts, scalp tissue defects, large-sized skull defect, and autologous bone flaps. importantly, implants with embedded neurotechnology were not associated with increased odds of reoperation., Conclusions: These results allow for comparison of multiple factors that impact risk of complications after cranioplasty and lay the foundation for development of a cranioplasty risk stratification scheme. Further research in neuroplastic surgery is warranted to examine how designated centers concentrating on adult neuro-cranial reconstruction and multidisciplinary collaboration may lead to improved cranioplasty outcomes and decreased risks of complications in neurosurgical patients., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 by Mutaz B.

- Abstract
Abstract: Orbital floor fractures result in posterior globe displacement known as enophthalmos, and diplopia due to extraorbital soft tissue impingement. Surgical repair may involve the use of autolo-gous or synthetic materials. Previous studies have demonstrated a higher prevalence of orbital floor fractures among lower socioeconomic status (SES) populations. The authors aimed to characterize the impact of socioeconomic status on surgical management, outcomes, and use of synthetic orbital implant. The authors conducted a cross-sectional study of adult orbital floor fracture patients from 2002 to 2017 using the National Inpatient Sample. Among patients who underwent surgical treatment, our study found decreased synthetic orbital implant use among uninsured and Black patients and decreased home discharge among Medicare patients. There were no differences in orbital reconstruction. Further research is needed to elucidate possible mechanisms driving these findings., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 by Mutaz B. Habal, MD.)

- Abstract
Background: Despite significant advances in the management of frontal sinus fractures, there is still a paucity of large-cohort data, and a comprehensive synthesis of the current literature is warranted. The purpose of this study was to present an evidence-based overview of frontal sinus fracture management and outcomes., Methods: A comprehensive literature search of PubMed and MEDLINE was conducted for studies published between 1992 and 2020 investigating frontal sinus fractures. Data on fracture type, intervention, and outcome measurements were reported., Results: In total, 456 articles were identified, of which 53 met our criteria and were included in our analysis. No statistically significant difference in mechanism of injury, fracture pattern, form of management, or total complication rate was identified. We found a statistically significant increase in complication rates in patients with nasofrontal outflow tract injury compared with those without., Conclusions: Frontal sinus fracture management is a challenging clinical situation, with no widely accepted algorithm to guide appropriate management. Thorough clinical assessment of the fracture pattern and associated injuries can facilitate clinical decision-making., (Copyright © 2022 The Authors.

- Abstract
Abstract: This study is the first to investigate pediatric craniomaxillofacial (CMF) trauma patients that present with concomitant burns. The authors aim to identify differing etiologies, presentations, facial fracture patterns, interventions, and outcomes between pediatric CMF trauma patients with versus without concomitant burns. In this retrospective cohort study of a tertiary care center between the years 1990 and 2010, concomitant burns were identified among pediatric patients presenting with CMF fractures. Patient charts were reviewed for demographics, presentation, burn characteristics (total body surface area %, location, and degree), imaging, interventions, involvement of child protective services, and long-term outcomes. Data were analyzed using two-tailed Student t tests and chi-square analysis. Of the identified 2966 pediatric CMF trauma patients (64.0% boys; age 7 ± 4.7 years), 10 (0.34%) patients presented with concomitant burns. Concomitant burn and CMF traumas were more likely to be due to penetrating injuries (P < 0.0001) and had longer hospital lengths of stay (13 ± 18.6 versus 4 ± 6.2 days, P < 0.0001). 40% were due to child abuse, 40% due to motor vehicle collisions, and 20% due to house fires. All four child abuse patients presented in a delayed fashion; operative burn care was prioritized and 70% of the CMF fractures were managed nonoperatively. Concomitant burn and CMF trauma is a rare injury pattern in pediatrics and warrants skeletal surveys with suspicious injury patterns. Future research is necessary to develop practice guidelines., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 by Mutaz B. Habal, MD.)

- Abstract
Background: Combined symphyseal-condylar mandible fractures are relatively common but difficult to manage in children. This study investigated the cause and management of symphyseal-condylar fractures in pediatric patients., Methods: This study presents a retrospective review and expert opinion of pediatric symphyseal-condylar mandibular fracture management at the authors' institution between 1990 and 2019. National data from the Healthcare Cost and Utilization Project Kids' Inpatient Database (2000 to 2016) were used to determine whether institutional data had national applicability., Results: Twenty-one patients at the authors' institution met inclusion criteria. Of these patients, 26.7 percent of deciduous dentition patients underwent open reduction and internal fixation, 40 percent underwent closed treatment (maxillomandibular fixation), and 33.3 percent received a soft diet. All mixed dentition patients underwent open reduction and internal fixation or closed treatment; all permanent dentition patients underwent open reduction and internal fixation. The national database (n = 1708) demonstrated similar treatment patterns: most permanent dentition patients (88.7 percent) underwent open reduction and internal fixation, most mixed dentition patients (79.2 percent) underwent closed treatment, and among deciduous dentition patients, 53.5 percent patients received a soft diet; 38 percent received closed treatment. In this study, the overall posttreatment complication rate was 62.5 percent among open reduction and internal fixation patients, 14.3 percent among closed treatment patients, and 16.7 percent among patients treated with a soft diet., Conclusions: Symphyseal-condylar mandibular fractures were associated with substantial morbidity in children. The authors created a treatment algorithm to maximize outcomes in children who suffer from this challenging fracture pattern., Clinical Question/level of Evidence: Therapeutic, III., (Copyright © 2021 by the American Society of Plastic Surgeons.)

- Abstract
Background: Naso-orbitoethmoid fractures associated with ipsilateral zygomaticomaxillary complex fractures are more challenging injuries than zygomaticomaxillary complex fractures alone. However, there is a paucity of information on this complex fracture pattern in the pediatric population. This study investigated the cause, treatment, and outcomes of combined zygomaticomaxillary complex and naso-orbitoethmoid fractures versus isolated zygomaticomaxillary complex fractures in pediatric patients., Methods: This was a 25-year retrospective cohort study of pediatric patients who presented to a single institution with zygomaticomaxillary complex fractures. Baseline patient demographics and clinical information, and concomitant injuries, treatment/operative management, and postoperative complications/deformities were recorded and compared between patients with combined zygomaticomaxillary complex and naso-orbitoethmoid fractures and patients with isolated zygomaticomaxillary complex fractures., Results: Forty-nine patients were identified to have had zygomaticomaxillary complex fractures in the authors' 25-year study period, of whom 46 had adequate clinical documentation and follow-up. Seventeen patients had combined zygomaticomaxillary complex-naso-orbitoethmoid fractures, of whom six had panfacial fractures. Both patient groups (zygomaticomaxillary complex only and combined zygomaticomaxillary complex-naso-orbitoethmoid fractures) were similar in terms of demographics. However, a significantly greater proportion of combined fracture patients experienced postoperative complications compared to isolated zygomaticomaxillary complex fracture patients, even after excluding those with panfacial fractures (87.5 percent versus 35.3 percent; p < 0.001). Enophthalmos (37.5 percent) and midface growth restriction (37.5 percent) were the two most common complications/deformities in all combined fracture patients., Conclusions: High-impact trauma can lead to zygomaticomaxillary complex fractures with associated naso-orbitoethmoid fractures in children. This injury pattern was found to cause significantly greater postoperative morbidity than isolated zygomaticomaxillary complex fractures alone. Thus, pediatric patients presenting with this complex facial fracture pattern should be closely monitored., Clinical Question/level of Evidence: Risk, II., (Copyright © 2021 by the American Society of Plastic Surgeons.)

- Abstract
Background: The purpose of this study was to examine injury patterns in pediatric mandibular condylar fractures and to propose and evaluate the validity of an institutional treatment algorithm for such fractures., Methods: A retrospective chart review was conducted on pediatric patients who presented to the authors' institution with isolated mandibular condylar fractures between 1990 and 2016. Patients were categorized by dentition, and information regarding demographics, injury characteristics, management, and complications was compiled., Results: Forty-three patients with 50 mandibular condylar fractures were identified. Twelve patients (27.9 percent) had deciduous dentition, 15 (34.9 percent) had mixed dentition, and 16 (37.2 percent) had permanent dentition. The most common fracture pattern in all groups was diacapitular [n = 30 (60 percent)]; however, older groups showed higher rates of condylar base fractures and bilateral fractures (p = 0.029 and p = 0.011, respectively). Thirty-one patients (72.1 percent) were treated with nonoperative management, 10 (23.2 percent) with closed treatment and mandibulomaxillary fixation, and two (4.7 percent) with open treatment and mandibulomaxillary fixation; nonoperative treatment was more common in younger patients (p = 0.008). Management for 10 patients (23.2 percent) was nonadherent to the treatment algorithm. Eight patients had complications (18.6 percent). Common complications included temporomandibular joint ankylosis (n = 2) and malocclusion (n = 2). Although complications were seen in all groups, adherence to the algorithm was associated with an 81.8 percent reduction in odds of complications (p = 0.032)., Conclusions: Nonoperative management has a low complication rate in deciduous children. Children with permanent/mixed dentition may undergo closed treatment and mandibulomaxillary fixation if they have malocclusion/contralateral open bite, significant condylar dislocation, and ramus height loss greater than 2 mm., Clinical Question/level of Evidence: Therapeutic, III., (Copyright © 2021 by the American Society of Plastic Surgeons.)

- Abstract
Background: Fractures of the orbital roof require high-energy trauma and have been linked to high rates of neurologic and ocular complications. However, there is a paucity of literature exploring the association between injury, management, and visual prognosis., Methods: The authors performed a 3-year retrospective review of orbital roof fracture admissions to a Level I trauma center. Fracture displacement, comminution, and frontobasal type were ascertained from computed tomographic images. Pretreatment characteristics of operative orbital roof fractures were compared to those of nonoperative fractures. Risk factors for ophthalmologic complications were assessed using univariable/multivariable regression analyses., Results: In total, 225 patients fulfilled the inclusion criteria. Fractures were most commonly nondisplaced [n = 118 (52.4 percent)] and/or of type II frontobasal pattern (linear vault involving) [n = 100 (48.5 percent)]. Eight patients underwent open reduction and internal fixation of their orbital roof fractures (14.0 percent of displaced fractures). All repairs took place within 10 days from injury. Traumatic optic neuropathy [n = 19 (12.3 percent)] and retrobulbar hematoma [n = 11 (7.1 percent)] were the most common ophthalmologic complications, and led to long-term visual impairment in 51.6 percent of cases., Conclusions: Most orbital roof fractures can be managed conservatively, with no patients in this cohort incurring long-term fracture-related complications or returning for secondary treatment. Early fracture treatment is safe and may be beneficial in patients with vertical dysmotility, globe malposition, and/or a defect surface area larger than 4 cm2. Ophthalmologic prognosis is generally favorable; however, traumatic optic neuropathy is major cause of worse visual outcome in this population., Clinical Question/level of Evidence: Risk, III., (Copyright © 2020 by the American Society of Plastic Surgeons.)

- Abstract
Background: Mandibular body fractures can cause severe and long-term morbidity in the pediatric population. Nonetheless, there is insufficient data on the treatment and management of this specific fracture type in children. This study aimed to investigate the etiology, treatment, and outcomes of pediatric mandibular body fractures by analyzing our institution's experience managing these uncommon injuries., Methods: This was a 30-year retrospective, longitudinal cohort study of pediatric patients presenting to a single institution with isolated, unilateral, mandibular body fractures. Patient data was extracted from electronic medical records, while subgroup analysis was completed by dentition stage., Results: A total of 14 patients met inclusion criteria, of whom 8 (57.1%) had deciduous, 3 (21.4%) had mixed, and 3 (21.4%) had permanent dentition. Deciduous dentition patients with displaced, mobile or comminuted fractures underwent open reduction and internal fixation (ORIF), while those with nondisplaced and/or nonmobile fractures received soft diet or closed treatment with maxillomandibular fixation. For the mixed dentition cohort, all patients (100%) received closed treatment with maxillomandibular fixation. Among permanent dentition patients, most patients (66.6%) underwent ORIF regardless of fracture severity. The post-ORIF complication rate was 20% (dental maleruption)., Conclusions: Isolated, unilateral mandible body fractures are relatively uncommon in the pediatric population, and management differs by dentition stage and injury pattern. While isolated body fractures had considerable associated morbidity, this fracture pattern did not result in major growth restrictions or malformations., Competing Interests: Dr. Dorafshar receives indirect research support and is entitled to royalties from KLS Martin.

23. Resolution of Vertical Gaze Following a Delayed Presentation of Orbital Floor Fracture With Inferior Rectus Entrapment: The Contributions of Charles E. Iliff and Joseph S. Gruss in Orbital Surgery.

Gowda AU, Manson PN, Iliff N, Grant MP, and Nam AJ
- Abstract
Introduction: Orbital floor fractures occur commonly as a result of blunt trauma to the face and periorbital region. Orbital floor fractures with a "trapdoor" component allow both herniation and incarceration of contents through a bone defect into the maxillary sinus as the bone rebounds faster than the soft tissue, trapping muscle, fat, and fascia in the fracture site. In children, the fractured floor, which is often hinged on one side, tends to return toward its original anatomical position due to the incomplete nature of the fracture and elasticity of the bone. The entrapment of the inferior rectus muscle itself is considered a true surgical emergency-prolonged entrapment frequently leads to muscle ischemia and necrosis leading to permanent limitation of extraocular motility and difficult to correct diplopia. For this reason, prompt surgical intervention is recommended by most surgeons. In adults, true entrapment of the muscle itself is not as common because the orbital floor is not as elastic and fractures are more complete., Methods: We present an adult patient with an isolated orbital floor fracture with clinical and radiologic evidence of true entrapment of the inferior rectus muscle itself., Results: Despite the delayed surgical repair (4 days after the injury), the patient's inferior rectus muscle function returned to near normal with mild upward gaze diplopia., Conclusions: Inferior rectus entrapment in adults may more likely be associated with immobilization of the muscle without total vascular compression/incarceration significant enough to lead to complete ischemic necrosis., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2020.)

- Abstract
Background: Mandible angle fractures can result in significant, long-term morbidity in children. However, management of this particular mandibular fracture type is not well-characterized in the pediatric population. This study investigated isolated mandibular angle fractures in the pediatric patients., Methods: This was a 30-year retrospective, longitudinal cohort study of pediatric patients presenting to a single institution with mandibular angle fractures. Patient data were abstracted from electronic medical records. Subgroup analyses were completed by dentition stage., Results: Seventeen patients met inclusion criteria, of whom 6 (35.3%) had deciduous, 4 (23.5%) had mixed, and 7 (41.2%) had permanent dentition. Deciduous/mixed dentition patients with mobile, displaced fractures underwent ORIF, whereas those with nondisplaced fractures underwent treatment with soft diet. Among permanent dentition patients, most patients (71.4%) underwent ORIF regardless of fracture severity. The post-ORIF complication rate was 55.6%; no complications were reported after soft diet or closed treatment (Fischer exact: P = 0.05). The most common post-ORIF complication was alveolar nerve paresthesia (17.6%) and post-ORIF complication rates did not vary by age (deciduous: 16.7%, mixed: 25.0%, permanent: 42.9%, Fischer exact: P = 0.80). ORIF patients who received a single upper border miniplate had a lower complication rate (42.9%) than other plating methods (upper and lower miniplates-100%). Fracture severity was predictive of post-ORIF complications (odds ratio: 2.23, 95% confidence interval: 2.22-2.24, P < 0.0001)., Conclusions: Isolated mandible angle fractures were relatively rare in children, and treatment requirements varied by injury severity and dentition stage. Although isolated angle fractures had substantial associated morbidity, this fracture pattern did not result in notable growth limitations/deformity.

- Abstract
Background: Isolated symphyseal or parasymphyseal mandibular fractures can confer significant morbidity in children. However, this mandibular injury pattern has not been well-characterized in children. This study investigated isolated symphyseal/parasymphyseal mandibular fractures in pediatric patients., Methods: This was a 29-year retrospective, longitudinal cohort study of pediatric patients who presented to a single institution with isolated symphyseal/parasymphyseal mandibular fractures. Patient data were abstracted from medical records and compared between patients of varying dentition stages., Results: Fourteen patients met inclusion criteria during the study period, of whom 2 (14.3%) had deciduous dentition, 7 (50.0%) had mixed dentition, and 5 (35.7%) had permanent dentition. Patients with deciduous dentition were significantly more likely to receive soft diet or closed treatment with mandibulomaxillary fixation than open reduction and internal fixation when compared to patients with mixed or permanent dentition (p = 0.04). The post-treatment complication rate was 40% among all patients treated with open reduction and internal fixation, 16.7% among patients who underwent closed treatment with mandibulomaxillary fixation, and 75% amongst patients treated with soft diet (though 2 patients who received soft diet had permanent dentition and thus were inappropriately managed). The most common complication overall was malocclusion (20%). A treatment algorithm was proposed based on study data; adherence to the algorithm significantly decreased odds of complications (odds ratio: 0.03, 95% confidence interval:0.001-0.6)., Conclusions: The etiology, management, and outcomes of children with isolated symphyseal or parasymphyseal mandibular fractures at our institution varied by dentition stage. The authors proposed a treatment algorithm in order to optimize outcomes of symphyseal/parasymphyseal mandibular fractures in this patient population.

- Abstract
Background: Currently, the pathogenesis of leptomeningeal cysts, also known as growing skull fractures, is still debated. The purpose of this study was to examine the specific skull fracture characteristics that are associated with the development of growing skull fractures and describe the authors' institutional experience managing this rare entity., Methods: A retrospective cohort study was performed that included all patients younger than 5 years presenting to a single institution with skull fractures from 2003 to 2017. Patient demographics, cause of injury, skull fracture characteristics (e.g., amount of diastasis, linear versus comminuted fracture), concomitant neurologic injuries, and management outcomes were recorded. Potential factors contributing to the development of a growing skull fracture and neurologic injuries associated with growing skull fractures were evaluated using univariate logistic regression., Results: A total of 905 patients met the authors' inclusion criteria. Of these, six (0.66 percent) were diagnosed with a growing skull fracture. Growing skull fractures were more likely to be comminuted (83.3 percent versus 40.7 percent; p = 0.082) and to present with diastasis on imaging (100 percent versus 26.1 percent; p < 0.001; mean amount of diastasis, 7.1 mm versus 3.1 mm; p < 0.001). Univariate logistic regression analysis confirmed the role of a comminuted fracture pattern (OR, 7.572) and the degree of diastasis (OR, 2.081 per mm diastasis) as significant risk factors for the development of growing skull fractures., Conclusions: The authors' analysis revealed that fracture comminution and diastasis width are associated with the development of growing skull fractures. The authors recommend dural integrity assessment, close follow-up, and early management in young children who present with these skull fracture characteristics., Clinical Question/level of Evidence: Risk, III.

- Abstract
Background: The purpose of this study was to assess the incidence, cause, characteristics, presentation, and management of pediatric frontal bone fractures., Methods: A retrospective cohort review was performed on all patients younger than 15 years with frontal fractures that presented to a single institution from 1998 to 2010. Charts and computed tomographic images were reviewed, and frontal bone fractures were classified into three types based on anatomical fracture characteristics. Fracture cause, patient demographics, management, concomitant injuries, and complications were recorded. Primary outcomes were defined by fracture type and predictors of operative management and length of stay., Results: A total of 174 patients with frontal bone fractures met the authors' inclusion criteria. The mean age of the patient sample was 7.19 ± 4.27 years. Among these patients, 52, 47, and 75 patients were classified as having type I, II, and III fractures, respectively. A total of 14, 9, and 24 patients with type I, II, and III fractures underwent operative management, respectively. All children with evidence of nasofrontal outflow tract involvement and obstruction underwent cranialization (n = 11)., Conclusions: The authors recommend that type I fractures be managed according to the usual neurosurgical guidelines. Type II fractures can be managed operatively according to the usual pediatric orbital roof and frontal sinus fracture indications (e.g., significantly displaced posterior table fractures with associated neurologic indications). Lastly, type III fractures can be managed operatively as for type I and II indications and for evidence of nasofrontal outflow tract involvement. The authors recommend cranialization in children with nasofrontal outflow tract involvement., Clinical Question/level of Evidence: Risk, II.

Wang HD, Susarla SM, Yang R, Mundinger GS, Schultz BD, Banda A, MacMillan A, Manson PN, Nam AJ, and Dorafshar AH
- Abstract
The purpose of this study was to compare the functional outcomes of different types of bilateral mandibular condylar fractures. This was a retrospective study of patients with bilateral mandibular condylar fractures at a level-1 trauma center over a 15-year period. The primary predictor variable was fracture pattern, classified as type I (bilateral condylar), type II (condylar-subcondylar), or type III (bilateral subcondylar). Secondary predictor variables were demographic, injury-related, and treatment factors. Bivariate associations between the predictors and complication rates were computed; a multiple logistic regression model was utilized to adjust for confounders and effect modifiers. Thirty-eight subjects with bilateral condylar injuries met the inclusion criteria. The sample's mean age was 37.6 + 18.2 years, and 16% were female. The most common mechanisms of injury were motor vehicle collisions (53%) and falls (29%). Seventy-four percent had associated noncondylar mandibular fractures, and 32% of cases had concomitant midface fractures. Fifty-three percent of cases were classified as type I, 21% as type II, and 26% as type III. Ten subjects (26%) were managed with open reduction and internal fixation. The average length of follow-up was 4.5 + 6.3 months. After adjusting for confounders and effect modifiers, the type of fracture was a significant predictor of functional complications with type II injuries having the highest likelihood of a poor functional outcome (odds ratio: 7.77, 95% confidence interval: 1.45-41.53, p = 0.02). Asymmetric bilateral mandibular condylar fractures may be associated with an increased risk of poor functional outcomes.

- Abstract
Background: The purpose of this study was to investigate surgical outcomes with the use of resorbable plating systems for the repair of craniomaxillofacial trauma in the pediatric population., Methods: A systematic review of the literature was performed. A descriptive analysis, operative technical data, outcomes, and postoperative complications with the use of absorbable plating systems for craniomaxillofacial trauma were included., Results: The systematic literature review identified 1264 abstracts, of which only 19 met inclusion criteria. From these 19 studies, 312 clinical cases with 443 facial fractures that were treated with absorbable fixation systems were extracted for analysis. The review identified only level III/IV (n = 17) and level V (n = 2) studies. Minor and major complications were rare, occurring in 5.45 percent (n = 17) and 3.21 percent (n = 10) of cases, respectively. The most common complications were surgical-site infections (n = 4) and plate extrusion (n = 4)., Conclusions: This report is, to the authors' knowledge, one of the first comprehensive reports on the use of absorbable plating systems for pediatric craniomaxillofacial trauma. Their analysis suggests that the use of absorbable fixation devices for pediatric craniomaxillofacial trauma is relatively safe, with a low-risk profile. Outcome studies with longer follow-up periods specifically investigating facial growth, reoperation rates, standardized surgical outcome metrics, and cost are necessary to effectively compare these fixation devices to titanium alternatives for craniomaxillofacial trauma.

- Abstract
Purpose: In pediatric patients with craniomaxillofacial (CMF) trauma, evaluation for cervical spine injury (CSI) is critical, but there are no studies investigating CSI in this unique population. The aim of this study was to measure the frequency of CSI in the pediatric CMF fracture population., Materials and Methods: A retrospective cohort study of all pediatric patients who presented to the Johns Hopkins Hospital Emergency Department (Baltimore, MD) with CMF fractures were examined for concurrent CSIs. Patient charts were reviewed for mechanism of injury, type and level of CSI, type and location of CMF fracture patterns, and overall outcome. Data were analyzed for correlation and statistical relevance., Results: A total of 2,966 pediatric patients (1,897 boys [64.0%]; age range, 0 to 15 yr; average age, 7 ± 4.73 yr) were identified from 1990 to 2010 to have CMF fractures. Of these patients, only 5 children were found to have concomitant CSIs (frequency, 0.169%). The frequency of CSI in patients with CMF fracture and deciduous, mixed, and permanent dentition was 0, 0.307, and 0.441%, respectively. Of the 5 identified cases, 4 had concomitant middle-third facial skeletal fracture, 4 had concomitant upper-third cranial skeletal fracture, and 2 had concomitant lower-third cranial skeletal fracture., Conclusion: CSIs in pediatric patients with CMF fracture are rare (frequency, 0.169%); this is considerably lower than the reported ranges in adults (3.69 to 24%). No child with deciduous dentition was found to have a CSI. The lack of CSI in deciduous patients with CMF fracture could be explained by the anatomic differences between pediatric and adult cervical spines and supports conservative imaging for children in this age group (level of evidence, III)., (Copyright © 2019 American Association of Oral and Maxillofacial Surgeons.

- Abstract
Background: Currently, there is a paucity of information on the presentation and proper management of pediatric nasoorbitoethmoid fractures. The purpose of this study was to examine the incidence, cause, associated injuries, and management of these fractures. Furthermore, the authors sought to assess outcomes after transnasal wiring or suture canthopexy for type III nasoorbitoethmoid fractures., Methods: A retrospective cohort review was performed of all patients with nasoorbitoethmoid fractures who presented to a Level I trauma center from 1990 to 2010. Charts and computed tomographic imaging were reviewed, and nasoorbitoethmoid fractures were labeled based on the Markowitz-Manson classification system. Patient fracture patterns, demographics, characteristics, and outcomes were recorded. Univariate and multivariate methods were used to compare groups., Results: A total of 63 pediatric patients were identified in the study period. The sample's mean age was 8.78 ± 4.08 years, and 28.6 percent were girls. The sample included 18 type I injuries, 28 type II injuries, and 17 type III injuries. No significant demographic differences were found between patients with type I, II, and III fractures (p > 0.05). Operative intervention was pursued in 16.7, 46.4, and 82.4 percent of type I, II, and III nasoorbitoethmoid fractures, respectively. In patients with type III nasoorbitoethmoid fractures, no patients with transnasal wiring developed telecanthus., Conclusions: Pediatric nasoorbitoethmoid fractures are uncommon injuries. Type I fracture can often be treated with close observation. However, type II and III injury patterns should be evaluated for operative intervention. Transnasal wiring is an effective method to prevent traumatic telecanthus deformity in type III fracture patterns.

- Abstract
Introduction: Numerous techniques have been described to overcome scalp deficiency and high-tension closure at time of cranioplasty. However, there is an existing controversy, over when and if a free flap is needed during complex skull reconstruction (ie, cranioplasty). As such the authors present here our experience using full-thickness skin grafts (FTSGs) to cover local defects following scalp adjacent tissue transfer in the setting of cranioplasty., Methods: By way of an institutional review board-approved database, the authors identified patients treated over a 3-year period spanning January 2015 to December 2017, who underwent scalp reconstruction using the technique presented here. Patient demographics, clinical characteristics, technical details, outcomes, and long-term follow up were statistically analyzed for the purpose of this study., Results: Thirty-three patients, who underwent combined cranioplasty and scalp reconstruction using an FTSG for local donor site coverage, were identified. Twenty-five (75%) patients were considered to have "high complexity" scalp defects prior to reconstruction. Of them, 12 patients (36%) were large-sized and 20 (60%) medium-sized; 21 (64%) grafts were inset over vascularized muscle or pericranium while the remaining grafts were placed over bare calvarial bone. In total, the authors found 94% (31/33) success for all FTSGs in this cohort. Two of the skin grafts failed due to unsuccessful take. Owing to the high rate of success in this series, none of the patient's risk factors were found to correlate with graft failure. In addition, the success rate did not differ whether the graft was placed over bone verses over vascularized muscle/pericranium., Conclusion: In contrary to previous studies that have reported inconsistent success with full-thickness skin grafting in this setting, the authors present a simple technique with consistent results-as compared to other more complex reconstructive methods-even in the setting of highly complex scalp reconstruction and simultaneous cranioplasty.

- Abstract
Background: Relatively few reports have been published investigating the operative management of pediatric zygomaticomaxillary complex fractures. The purpose of this study was to assess pediatric zygomaticomaxillary complex fracture management and associated complications, and potentially describe a standard treatment paradigm for these cases., Methods: A retrospective cohort review was performed of all patients younger than 15 years presenting to a single institution with zygomaticomaxillary complex fractures from 1990 to 2010. Patient demographics, concomitant injuries, management details, and complications were recorded. Complications were compared among patients by dentition stage, number of fixation points, and identity of fixation sites., Results: A total of 36 patients with 44 unique zygomaticomaxillary complex fractures met the authors' inclusion criteria. Thirty-two fractures exhibited at least 2.0 mm of diastasis along at least one buttress (73 percent), and all but one of these were managed operatively. Among operatively managed patients with deciduous dentition, two-point fixation was associated with a lower overall complication rate compared with one- and three-point fixation (0 percent versus 75 percent and 75 percent; p = 0.01). Furthermore, rigid plate-and-screw fixation at the zygomaticomaxillary buttress was not associated with an increased complication rate in operatively managed patients with deciduous dentition (40 percent versus 50 percent; p = 0.76)., Conclusions: The authors' results suggest that two-point fixation is an effective management strategy for repair of displaced zygomaticomaxillary complex fractures in children. In addition, rigid plate-and-screw fixation at the zygomaticomaxillary buttress in children with deciduous dentition appears to be safe and effective when performed., Clinical Question/level of Evidence: Therapeutic, III.

- Abstract
Purpose: Nonunion is an uncommon complication after mandibular fractures. The purpose of this investigation was to compare outcomes of patients with mandibular fracture nonunion who were treated with a 1- versus 2-stage approach and propose a pragmatic treatment algorithm for surgical management based on preoperative characteristics., Materials and Methods: The authors conducted a retrospective study consisting of patients who presented to 2 level 1 trauma centers for the management of mandibular fracture nonunion over a 10-year period. The primary predictor variable was 1- versus 2-stage treatment. Outcomes were examined to propose a treatment algorithm., Results: Eighteen patients were included in the study. The sample's mean age was 44.0 ± 19.3 years and most were men (88.9%). Mandibular angle and body accounted for 77.8% of cases. A single-stage approach was used in 13 patients (72.2%). Bone grafts or vascularized bone flaps were required in 13 patients (72.2%). Patients who required 2-stage treatments had intraoral soft tissue defects. Mean length of follow-up was 13.3 ± 20.4 months. All patients achieved bony union, with complications occurring in 5 patients (27.8%). The authors' 10-year experience was used to formulate a treatment algorithm based on bony defect size and soft tissue status, which can be used to inform optimal surgical management., Conclusions: Nonunion of mandibular fractures is an infrequent and complex condition requiring careful and deliberate surgical management. A single-stage approach is appropriate in most cases and does not negatively affect outcomes. Bony defect size and soft tissue status are essential parameters for determining the approach and timing of reconstruction., (Copyright © 2018 American Association of Oral and Maxillofacial Surgeons.

- Abstract
Historically, periodic academic meetings held by surgical societies have set the stage for discussion and exchange of ideas, which in turn have led to advancement of clinical practices. Since 2007, the AONA State of the Art: Facial Reconstruction and Transplantation Meeting (FRTM) has been organized to provide a forum for specialists around the world to engage in open conversation about the approaches currently at the forefront of facial reconstruction. Review of registration data of FRTM iterations from 2007 to 2015 was performed. The total number of participants, along with their level of medical training, location of practice, and medical specialty, was recorded. Additionally, academic programs and 2015 participant feedback were evaluated. From 2007 to 2011, there was a decrease in the overall number of participants, with a slight increase in the number of clinical specialties present. In 2013, a sharp increase in total participants, international attendance, and represented clinical specialties was observed. This trend continued in 2015. Adjustments to academic programs have included reorganization of lectures and optimization of content. FRTM is a unique forum for multidisciplinary professionals to discuss the evolving field of facial reconstruction and join forces to accelerate progress and improve patient care.

- Abstract
Background: The purpose of this study was to identify factors associated with the decision to perform open reduction and internal fixation of mandibular condylar fractures., Methods: This was a retrospective cohort study of patients with mandibular condylar fractures managed by the plastic and reconstructive surgery, oral and maxillofacial surgery, and otorhinolaryngology services over a 15-year period. Bivariate associations and a multiple logistic regression model were computed for injury characteristics that were associated with open reduction and internal fixation. For all analyses, a value of p ≤ 0.05 was considered significant., Results: Six hundred fifty-four condylar injuries were identified in 547 patients. The sample's mean age was 36.0 ± 16.5 years, 20.5 percent were women, and 63 percent were Caucasian. The most common mechanisms of injury were motor vehicle collisions (49 percent), 53.4 percent involved the subcondylar region and 20 percent were bilateral injuries. Associated noncondylar mandibular fractures were present in 60 percent of cases; 20.7 percent were managed with open reduction and internal fixation. The overall complication rate was 21.6 percent. In a multiple logistic regression model, factors associated with an increased likelihood of open reduction and internal fixation were the presence of extracondylar mandibular injuries, condylar neck or subcondylar region injuries, increasing dislocation, and treatment by plastic and reconstructive surgery/oral and maxillofacial surgery (p ≤ 0.04)., Conclusions: Increasing severity of mandibular injury, lower level of fracture, joint dislocation, and treatment by plastic and reconstructive surgery/oral and maxillofacial surgery are associated with open reduction and internal fixation of mandibular condylar injuries., Clinical Question/level of Evidence: Risk, III.

- Abstract
Purpose: Management of zygomaticomaxillary complex (ZMC) fractures should be based on injury patterns and not on training background. This study assessed management decisions for ZMC injuries among surgeons with different training backgrounds., Materials and Methods: This was a cross-sectional study of surgeons who evaluated 5 ZMC injury cases. The primary predictor variable was training background: plastic and reconstructive surgeons (PRSs), craniofacial PRSs (c-PRSs), and oral and maxillofacial surgeons (OMSs). Other variables were years in practice, fellowship training, practice scope, and comfort with managing facial injuries. The primary outcome variable was management of the ZMC and orbital floor (operative vs nonoperative). Secondary outcome measurements were related to surgical approaches and fixation. Descriptive, bivariate, and regression statistics were computed., Results: Twenty-one surgeons (7 PRSs, 7 c-PRSs, and 7 OMSs) with an average of 14.4 ± 12.6 years of experience provided a total of 105 treatment plans. There was significant agreement between c-PRSs and OMSs for management of ZMC and orbital floor injuries (rs = 0.70 and 0.76, respectively; P ≤ .001). PRSs did not have substantial agreement with c-PRSs or OMSs with regard to ZMC fractures (rs = 0.39 and 0.49, respectively; P ≤ .06), but significant agreement with regard to orbital floor injuries (rs = 0.70 and 0.76, respectively; P < .001). In a regression model, injury pattern was the only factor associated with operative management (P ≤ .001)., Conclusions: There is substantial agreement between OMSs and c-PRSs regarding the management of ZMC fractures and associated orbital floor injuries., (Copyright © 2016 American Association of Oral and Maxillofacial Surgeons.

Bonawitz S, Crawley W, Shores JT, and Manson PN
- Abstract
The transconjunctival approach to the lower orbit is well described in the literature and has been used for both cosmetic and reconstructive purposes. When properly performed, it allows access to the orbital floor and inferior orbital rim with minimal lower lid morbidity and an inconspicuous scar. Many variations of this approach have been described and these can lead to confusion and uncertainty regarding the surgical technique including when and how to best utilize this approach in the traumatized eyelid. Residents and less experienced attendings employing this approach often fail to fully understand the technical and anatomic details that can make this a very fast and simple way to gain complete access to the inferior, medial, and lateral orbit while minimizing complications such as postoperative lid malposition and canthal deformities. We describe our method for transconjunctival access to the inferior orbital rim and orbital floor with specific attention to several precise surgical aspects that make this a fast and reliable technique with low morbidity and predictable architecture of closure.

- Abstract
Background: The purpose of this study is to identify whether intraoperative use of vasoactive medications increases the risk of free flap failure or complications through a systematic review and meta-analysis., Materials and Methods: PubMed/MEDLINE, EMBASE, and Scopus databases were searched for studies published through January 2015. English publications that met the following criteria were included: (1) adult patients undergoing head and neck free flap reconstruction; (2) comparison of patients with and without intraoperative vasopressor administration; and (3) documentation of flap failure rate and/or flap complications. The primary outcome was the incidence of flap failure. The secondary outcome was the incidence of overall flap complications. Meta-analysis was performed to obtain pooled odds ratios (ORs) of the effect of intraoperative use of vasopressors on flap failure and complication rates., Results: Four cohort studies met inclusion criteria. All studies were of high methodological quality with an average Methodological Index for Non-Randomized Studies score of 18.75 (range 16-23). A total of 933 patients undergoing head and neck free flap reconstruction were included. Meta-analysis demonstrated no statistically significant difference in the incidence of flap failure (2.9 vs. 3.6%; OR, 0.68; 95% confidence interval [CI], 0.23-1.99; p = 0.48) or incidence of flap complications (16.8 vs. 18.6%; OR, 0.92; 95% CI, 0.60-1.42; p = 0.71)., Conclusion: Based on the current evidence, intraoperative use of vasopressors has no impact on the incidence of flap failure or flap complications., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

- Abstract
Background: Traumatic optic neuropathy is characterized by sudden loss of vision following facial trauma leading to variable visual deficits. The purpose of this study was to evaluate recent institutional trends in the treatment of traumatic optic neuropathy, evaluate the outcomes of different treatment strategies, and identify factors associated with improved vision., Methods: Institutional review board approval was obtained to retrospectively review patients diagnosed with traumatic optic neuropathy at a high-volume trauma center from 2004 to 2012. Pretreatment and posttreatment visual acuity was compared using quantitative analysis of standard ophthalmologic conversion., Results: A total of 109 patients met inclusion criteria (74.3 percent male patients), with a mean age of 38.0 ± 17.5 years (range, 8 to 82 years). Management of traumatic optic neuropathy involved intravenous corticosteroids alone in 8.3 percent of patients (n = 9), 56.9 percent (n = 62) underwent observation, 28.4 percent (n = 31) had surgical intervention, and 6.4 percent (n = 7) underwent surgery and corticosteroid administration. Only 19.3 percent of patients returned for follow-up. Vision improved in 47.6 percent of patients, with a mean follow-up of 12.9 weeks. Patients younger than 50 years had a trend toward higher rates of visual improvement, 60 percent versus 16.7 percent (p = 0.15)., Conclusions: The majority of traumatic optic neuropathy patients are unlikely to return for a follow-up examination. Optic nerve decompression has fallen out of favor in the authors' institution, and observation is the most common management strategy. Outcomes following corticosteroid administration and observation are comparable., Clinical Question/level of Evidence: Therapeutic, IV.

- Abstract
Background: Multidisciplinary approaches have shown improved outcomes in secondary cranial reconstruction, however, scalp deficiency remains a common obstacle for tension-free scalp closure during cranioplasty. Therefore, our objective was to create an algorithmic approach using a novel concept of "component separation" to help minimize potential complications., Methods: The authors tested the hypothesis of achieving greater scalp mobility by way of "component separation" in a half-scalp, bilateral cadaver study, and describe within 2 clinical examples. Pterional-sized (N = 2) and hemicraniectomy-sized (N = 2) scalp flaps were dissected on 2 cadaveric heads using an internal control for each scenario. All flaps (N = 4) were created with (experimental group) and without (control group) "retaining ligament release." Total amounts of scalp mobility were measured bilaterally and compared accordingly., Results: Scalp flap mobility was calculated from the sagittal midline using identical arcs of rotation. With zero tension, we observed an increased distance of movement equaling 1 cm for the "experimental" pterional flap, compared with the contralateral "control." Similarly, we found an increase of additional 2 cm in scalp mobility for the "experimental" hemicraniectomy-sized flap., Conclusions: Tension free scalp closure is most critical for achieving improved outcomes in secondary cranial reconstruction. In this study, we show that a range of 1 to 2 additional centimeters may be gained through a component separation, which is of critical value during scalp closure following cranioplasty. Therefore, based on our high volume cranioplasty experience and cadaver study presented, we offer some new insight on methods to overcome scalp deficiency accompanying secondary cranial reconstruction.

- Abstract
Background: Knowledge of topographic skin thickness is important to plastic surgery of the face as it may guide resection and restoration in oncologic, aesthetic, and reconstructive procedures., Objective: The purpose of this study is to report the relative thickness of the face throughout 39 distinct subunits., Methods: Full-thickness punch biopsy samples were obtained at 39 predetermined anatomic locations of the face from 10 human cadaveric heads. Tissue was fixed in paraffin-embedded slides and analyzed using triplicate measurement of dermis and epidermis using computerized measurements. Data were analyzed using univariate statistical analysis and expressed as mean thickness values and relative thickness (RT) values based on the thinnest portion of the face., Results: The area of the face with the thickest dermis was the lower nasal sidewall (1969.2 µm, dRT: 2.59), and the thinnest was the upper medial eyelid (758.9 µm, dRT: 1.00). The area with the thickest epidermis was the upper lip (62.6 µm, eRT: 2.12), and the thinnest was the posterior auricular skin (29.6 µm, eRT: 1.00). Our results confirm that eyelid skin is the thinnest in the face. The thickest portions of the skin appeared to be in the lower nasal sidewall, but the measurements are comparable to those in the ala and posterior auricular skin, which are novel findings., Conclusions: The greatest epidermal, dermal and total skin thickness are found in the upper lip, right lower nasal sidewall, and left lower nasal sidewall respectively. The least epidermal skin thickness is in the posterior auricular skin. The least dermal skin thickness, and the least total skin thickness, are both in the upper medial eyelid., (© 2015 The American Society for Aesthetic Plastic Surgery, Inc.

- Abstract
Background: Posttraumatic midface pain secondary to injury of the anterior superior alveolar nerve (ASAN) is characterized as pain localized to the central and lateral incisors, canines, and maxilla. This nerve is susceptible to injury and subsequent formation of neuromas after midface trauma. Surgical intervention requires an accurate and precise understanding of the course of the ASAN., Methods: Dissections of 12 human cadaver heads were conducted to identify the course of the ASAN through the canalis sinuosus (CS). Fifty 1-mm slice face computed tomographic scans were evaluated to document the dimensions and course of the CS., Results: The ASAN branched laterally from the infraorbital nerve before reaching the infraorbital rim in all cadavers. The bifurcation occurred 18 mm posterior to the infraorbital rim (range, 10-30 mm). At a point 25 mm inferior to the infraorbital rim, the ASAN is found 3.4 mm lateral to the piriform aperture (range, 3-4 mm). Radiographic analysis demonstrated a 12.9-mm horizontal length of the CS across the anterior maxilla (SD, 2.2 mm), a distance of 4.8 mm between the piriform aperture and the CS (SD, 1.2 mm), and 11.7 mm vertical length of the CS along the piriform aperture (SD, 3.0 mm)., Conclusions: The ASAN maintains consistent coordinates at specific points along its course through the midface. An improved understanding of the course of the ASAN will guide future diagnosis of injury to this nerve and surgical intervention for patients with posttraumatic midface pain secondary to ASAN injury.
