Patient-Specific Implant Customization for Treatment of Internal Orbital Fractures Using Office-Based Three-Dimensional Printing.

OBJECTIVE: Three-dimensional (3D) modeling technology aids the reconstructive surgeon in designing and tailoring individualized implants for the reconstruction of complex craniofacial fractures. Three-dimensional modeling and printing have traditionally been outsourced to commercial vendors but can now be incorporated into both private and academic craniomaxillofacial practices. The goal of this report is to present a low-cost, standardized office-based workflow for restoring bony orbital volume in traumatic orbital fractures. METHODS: Patients with internal orbital fractures requiring open repair were identified. After the virtual 3D models were created by iPlan 3.0 Cranial CMF software (Brainlab), the models were printed using an office-based 3D printer to shape and modify orbital plates to correctly fit the fracture defect. The accuracy of the anatomic reduction and the restored bony orbital volume measurements were determined using postoperative computed tomography images and iPlan software. RESULTS: Nine patients fulfilled the inclusion criteria: 8 patients had unilateral fractures and 1 patient had bilateral fractures. Average image processing and print time were 1.5 hours and 3 hours, respectively. The cost of the 3D printer was $2500 and the average material cost to print a single orbital model was $2. When compared with the uninjured side, the mean preoperative orbital volume increase and percent difference were 2.7 ± 1.3 mL and 10.9 ± 5.3%, respectively. Postoperative absolute volume and percent volume difference between the orbits were -0.2 ± 0.4 mL and -0.8 ± 1.7%, respectively. CONCLUSIONS: Office-based 3D printing can be routinely used in the repair of internal orbital fractures in an efficient and cost-effective manner to design the implant with satisfactory patient outcomes.

The Digital Footprint of Academic Plastic Surgeons.

INTRODUCTION: The digital age and global pandemic have transformed the way patients select their plastic surgeon. However, as more patients turn to online resources, there is little information on the digital presence of academic plastic surgeons. METHODS: We identified all academic faculty from integrated and independent plastic surgery residency programs. Using a Google-based custom search, the top 10 search results for each surgeon were extracted and categorized as surgeon noncontrolled (eg, physician rating websites) or controlled (eg, social media, institutional, and research profiles). RESULTS: Eight hundred four academic plastic surgeons were included. Most search results were surgeon-noncontrolled sites (57%, n = 4547). Being male (odds ratio [OR], 0.60, P = 0.0020) and holding a higher academic rank (OR = 0.61, P < 0.0001) significantly decreased the prevalence of physician rating websites, whereas career length was significantly associated with a greater number of rating websites (OR = 1.04, P < 0.0001). Surgeon-controlled websites were significantly influenced by academic rank and years in practice; higher academic rank was associated with more social media platforms (OR = 1.42, P = 0.0008), institutional webpages (OR = 1.57, P < 0.0001), and research profiles (OR = 1.62, P = 0.0008). Conversely, longer career duration was a predictor for fewer social media platforms (OR = 0.95, P < 0.0001) and institutional webpages (OR = 0.95, P < 0.0001). CONCLUSIONS: Academic plastic surgeons do not hold control of the majority of their search results. However, digitally savvy plastic surgeons can focus attention by building on certain areas to optimize their digital footprint. This study can serve as a guide for academic plastic surgeons wishing to control their online presence.

Integrated Plastic Surgery Residency Applicant Perceptions of Virtual Interviews.

PURPOSE: The 2020-2021 interview cycle for integrated plastic surgery applicants was the first to be held virtually because of the COVID-19 pandemic. Here, we detail the largest study on integrated plastic surgery applicant perceptions after the virtual interview cycle. METHODS: A 35-question institutional review board-approved survey was distributed to medical students who had applied to the Johns Hopkins/University of Maryland or University of California San Diego integrated residency programs during the 2020-2021 interview cycle. Survey questions assessed the structure, strengths, and weaknesses of the exclusively virtual interview process. Survey administration and data collection were performed using the Qualtrics platform. RESULTS: Of 318 distributed surveys, 94 were completed. In addition, 91.5% of respondents preferred in-person interviews before the interview season, whereas 54.3% preferred in-person interviews afterward. Applicants who favored virtual interviews did not view being unable to physically meet with program staff as a detriment (P = .001) and felt they could effectively advocate for themselves (P = .002). Overall, the most cited strengths were the ability to complete more interviews (P = .01) and cost benefits (P = .02). Criticisms were directed at the impersonal nature of the exchange (86.2%), lack of physical tour (56.4%), and difficulties at self-advocacy (52.1%). CONCLUSION: Preference for virtual interviews increased from 7.5% to 34.0% after the virtual interview cycle. For several students, the ideal interview structure permits both in-person and virtual interviews to maximize flexibility. Augmenting with virtual city tours and one-on-one interviews may mitigate the impersonal nature of virtual interviews as perceived by some applicants.

Blunt Cerebrovascular Injury-Like Injury Observed in Patients With Craniofacial Self-Inflicted Gunshot Wounds.

BACKGROUND: Although blunt cerebrovascular injury (BCVI) is recognized as a risk factor for trauma morbidity and mortality, little is described regarding similar cerebrovascular injury (CVI) in patients with penetrating wounds. The authors aim to characterize these injuries in the craniofacial self-inflicted gunshot wound (SIGSW) population. METHODS: An institutional review board (IRB)-approved retrospective nstudy was conducted on patients presenting to the R Adams Cowley Shock Trauma Center with SIGSWs between 2007 and 2016. All CVIs were categorized by location, type, and associated neurologic deficits. Demographic data, patient characteristics, additional studies, and long-term outcomes were collected. A multivariate analysis determining independent predictors of CVI in the SIGSW population was performed. RESULTS: Of the 73 patients with SIGSWs, 5 (6.8%) had CVIs separate from the bullet/cavitation tract (distant CVIs) and 9 had CVIs along the bullet/cavitation tract (in-tract CVIs). A total of 55.6% of in-tract and 40% of distant injuries were missed on initial radiology read. One distant CVI patient suffered a stroke during admission. The anterior to posterior gunshot wound trajectory was positively associated with distant CVIs when compared with no CVIs ( P  = 0.01). Vessel dissection was more prevalent in patients with distant CVIs, when compared against patients with in-tract CVIs ( P  = 0.02). CONCLUSIONS: Nearly 20% of craniofacial SIGSW patients have CVIs and 6.8% have BCVI-like injuries, which is 2-to-6-fold times higher than traditional BCVIs. Craniofacial SIGSWs serve as an independent screening criterion with comparable screening yields; the authors recommend radiographic screening for these patients with particular scrutiny for CVIs as they are frequently missed on initial radiographic interpretations.

Many Moving Pieces: Virtual Preoperative Surgical Planning for Traumatic Occlusal Splints.

INTRODUCTION: Achieving anatomic reduction and re-establishing premorbid occlusion in patients with complex maxillomandibular fractures is challenging even for seasoned surgeons. Historically, surgeons have utilized occlusal splints to help establish occlusal relationships before fracture reduction and fixation. These acrylic splints are fabricated from dental impressions and require manual repositioning of tooth bearing segments along the fracture line to reapproximate premorbid occlusion. The process is laborious, requires a dental lab, and is less efficacious in edentulous patients or those with significantly comminuted fractures; as such it has largely fallen out of practice. Recently, with advances in virtual 3D modeling and printing, we demonstrate that occlusal splints can be designed from computed tomography scans, manipulated virtually, and printed without obtaining impressions from the patient. METHODS/RESULTS: In our series of 3 patients with complex maxillomandibular fractures, occlusal splints were created by 1) obtaining maxillofacial computed tomography scans, 2) reducing the fractures virtually, and 3) using orthognathic virtual surgery software to create the splint. The time between planning and delivery of the splint was 4 to 7 days. These splints were successfully utilized to help establish premorbid occlusion in conjunction with maxillomandibular fixation and aided in expeditious intraoperative fracture reduction and fixation. CONCLUSIONS: In the treatment of complex facial fractures, occlusal splints can be a useful adjunct in the operative reduction and fixation of fractures. With the advent of virtual preoperative surgical planning via 3D modeling and 3D printing, these occlusal splints can be created of a sufficient fidelity to avoid the strict need for dental impressions.

CT of Skull Base Fractures: Classification Systems, Complications, and Management.

As advances in prehospital and early hospital care improve survival of the head-injured patient, radiologists are increasingly charged with understanding the myriad skull base fracture management implications conferred by CT. Successfully parlaying knowledge of skull base anatomy and fracture patterns into precise actionable clinical recommendations is a challenging task. The authors aim to provide a pragmatic overview of CT for skull base fractures within the broader context of diagnostic and treatment planning algorithms. Laterobasal, frontobasal, and posterior basal fracture patterns are emphasized. CT often plays a complementary, supportive, or confirmatory role in management of skull base fractures in conjunction with results of physical examination, laboratory testing, and neurosensory evaluation. CT provides prognostic information about short- and long-term risk of cerebrospinal fluid (CSF) leak, encephalocele, meningitis, facial nerve paralysis, hearing and vision loss, cholesteatoma, vascular injuries, and various cranial nerve palsies and syndromes. The radiologist should leverage understanding of specific strengths and limitations of CT to anticipate next steps in the skull base fracture management plan. Additional imaging is warranted to clarify ambiguity (particularly for potential sources of CSF leak); in other cases, clinical and CT criteria alone are sufficient to determine the need for intervention and the choice of surgical approach. The radiologist should be able to envision stepping into a multidisciplinary planning discussion and engaging neurotologists, neuro-ophthalmologists, neurosurgeons, neurointerventionalists, and facial reconstructive surgeons to help synthesize an optimal management plan after reviewing the skull base CT findings at hand.

Global Burn Registry Perspective on Head and Neck Burns.

INTRODUCTION: As exposed regions of the body, the head and neck are at increased risk of burn injury. The cosmetic and functional importance of these anatomical regions means that burns can result in substantial morbidity and mortality. Our objective was to characterize predictive factors for surgery and discharge condition in patients with head and neck burns internationally. METHODS: We conducted an epidemiological study of all head and neck burns in 14 countries reported in the World Health Organization Global Burn Registry. Multivariate regression was used to identify variables predictive of surgical treatment and discharge condition. RESULTS: We identified 1014 patients who sustained head and neck burns; the majority were adults (60%). Both adults and children admitted to hospital with head and neck burn injuries were less likely to be treated surgically in lower-middle-income countries (LMIC) than in higher-income countries (P < 0.001). Increasing age and greater total surface body area (TBSA) were significant predictors of surgical intervention in children with head and neck burn injuries (P < 0.001). Total surface body area, associated injuries, ocular burns, female sex, and LMIC residency were all significant predictors of mortality in adult patients with head and neck burns (P < 0.050). Conversely, TBSA was the only variable that independently increased the risk of death in children with head and neck burns (P < 0.001). CONCLUSIONS: Certain groups are at increased risk of an adverse outcome after admission with a head and neck burn injury. Given the reduced incidence of surgical intervention and the elevated mortality risk in LMICs, global health initiatives should be targeted to these countries.

Survival Following Self-Inflicted Gunshot Injuries to the Face Using the National Trauma Data Bank.

INTRODUCTION: Self-inflicted gunshot wounds to the face frequently result in devastating injuries; however, there is a paucity of large experiences describing determinants of mortality and outcomes. METHODS: Using the National Trauma Databank from 2007 to 2015, patients suffering self-inflicted firearm facial injuries were included. RESULTS: Over 9 years 7869 patients were included: 87.7% were male, 46.4% suffered traumatic brain injury (TBI) and overall in-hospital mortality was 44.7%. The majority (67.8%) of in-hospital mortality occurred within the first 24 hours. Using multiple regression, advanced age (>65 years), presence of TBI, admission hypotension, and decreased Glasgow coma score were each independently associated with increased odds of mortality (all P < 0.001). Mandible or combined mandible/midface fracture injury patterns were most likely to survive (P < 0.001). Of those surviving to hospital discharge, the median [interquartile range] length of stay was 13 [6, 23] days, 86.6% required an intensive care unit stay with 67% requiring intubation and 42.5% tracheostomy. Among survivors, the combined mandible and midface fracture pattern resulted in the highest rates of tracheostomy (70.5%), gastrostomy tube placement (50.5%), and facial operations (87.0%) with a median [interquartile range] of 5 [3, 7] operative trips (all P < 0.001). CONCLUSIONS: Self-inflicted facial firearm injuries are highly morbid injuries with the majority of in-hospital deaths occurring the first hospital day. Differences including concomitant TBI, facial injury pattern, neurologic status, and presence of hypotension on admission were independently associated with survival/death. More extensive facial injuries (combined mandible and midface fracture patterns) were more likely to survive and required more intensive interventions.

A Cross-Sectional Analysis of American Insurance Coverage of Prominauris Otoplasty.

BACKGROUND: Prominent ears affect up to 5% of the population and can lead to social and psychological concerns at a critical time of social development. It can be addressed with an otoplasty, which is often considered a cosmetic procedure. The authors assessed insurance coverage of all indications of otoplasty and their medical necessity criteria. METHODS: A cross-sectional analysis was conducted of 58 insurance policies for otoplasty. The insurance companies were selected based on their state enrolment and market share. A web-based search and telephone interviews were utilized to identify the policies. Medically necessary criteria were then abstracted from the publicly available policies. RESULTS: Of the 58 insurance policies assessed, 25 (43%) provide coverage of otoplasty. There were 2 indications for coverage: hearing loss (n = 20, 80%) and normal approximation (n = 14, 56%), which would encompass prominent ears. Normal approximation was a covered indication for significantly fewer insurers than hearing loss (56% versus 80%, P = 0.0013). Of all the otoplasty policies which covered normal approximation, 21% (n = 3) addressed protruding ears as an etiology. Prominent ears were not included in any policies which covered hearing loss. All policies inclusive of prominent ears required a protrusion of >20 mm from the temporal surface of the head (n = 3, 100%). CONCLUSIONS: There is a great discrepancy in insurance coverage of otoplasty. A greater proportion of policies cover hearing loss compared to normal approximation. The authors encourage plastic surgeons to advocate for the necessity and coverage of normal approximation by insurers.

The Baltimore Criteria for an ethical approach to penile transplantation: a clinical guideline.

Significant advances and increasing acceptance of vascularized composite allotransplantation (VCA) have contributed to emerging success of penile transplantation. The aims of penile transplantation are fourfold: adequate urinary function, enabling natural erections, restoration of erogenous sensation and appearance of external male genitalia. Successful penile transplantation also requires limiting risks and managing complications of lifelong immunosuppression. Given the limited experience with this procedure, potential recipients must understand that penile transplantation is not currently standard of care and long-term functional outcomes are unknown. Moreover, these transplants are associated with complex ethical issues. Nevertheless, as the efficacy and safety of penile transplantation are being evaluated, clear indications for transplant are needed. Although preliminary recommendations have been proposed, a more comprehensive framework is needed. We performed a literature review for English language publications related to penile transplantation and ethics. Based on the results of the search, a review of prior recommendations, and our experience performing the first whole male genital allotransplantation including penis, scrotum and abdominal wall; screening and identifying potential donors and recipients for the procedure; and addressing the associated ethical issues, we propose guidelines for responsible penile transplantation: The Baltimore Criteria for an Ethical Approach to Penile Transplantation.

Sir Harold Delf Gillies-The Surgeon Artist.

Harold Gillies, a plastic surgeon who created the discipline of plastic surgery and trained hundreds of young surgeons, was foremost an artist. In a short historical perspective, we illustrate this facet of the Gillies' life through a friendship with the British ecologist William Sladen and a painting that Gillies drew during their encounters.

Orbital Injuries From Self-Inflicted Gunshots: Patterns, Management, and Visual Outcomes.

PURPOSE: Self-inflicted facial gunshots (SIGSWs) typically result in a spectrum of severe injuries to facial structures, including the orbit and globe. Roughly three-quarters of those who arrive to the hospital will survive their injuries, and recidivism is typically low. Therefore, effective management is paramount to preserve vision, and long-term quality of life. The objective of this study is to characterize the common injuries to the orbit, globe, and periocular structures following SIGSWs, their management, and their eventual visual and reconstructive outcomes. METHODS: Retrospective review of trauma registry records at a Level 1 trauma center for patients who presented alive following SIGSWs involving the globe and/or orbit from 2007 to 2016. RESULTS: Of the 47 patients who presented with SIGSWs to the orbit, 33 (70%) were discharged alive from the hospital. Management strategies for these patients fell into 3 groups, based on the involved structures: i) Open globe injuries (Type I: n = 12, 34%) ii) Orbital fractures with preserved globe and optic nerve (Type II: n = 15, 43%), and iii) Optic nerve injuries with preserved globe (Type III: n = 8, 23%). Compared with Type II and III injuries, patients who had Type I injuries were more likely to die prior to hospital discharge (46% vs. 20% vs. 12%, p = 0.04), undergo ophthalmologic intervention (73% vs. 6% vs. 11%, p = 0.01), and more surgery (6 vs. 3 vs. 0.5 mean surgeries, p < 0.001). Type II injuries most frequently underwent debridement and reconstruction of the bony orbit. Type III and Type I injuries were associated with worse initial and final visual acuity, with the majority (100% and 75%, respectively) having No Light Perception (NLP) on initial exam, and no visual recovery during the follow-up period (median follow up= 25 months). CONCLUSIONS: Management and visual outcomes of orbital injuries from SIGSWs is determined by whether the globe and optic nerve are preserved. Open globe injury by itself is associated with higher mortality and significant permanent vision loss.

The Prevalence of Blood-Borne Pathogens in Maxillofacial Trauma Patients.

BACKGROUND: Blood-borne pathogen infections (BPIs), caused by the human immunodeficiency virus, hepatitis C and hepatitis B viruses pose an occupational hazard to healthcare workers. Facial trauma reconstruction surgeons may be at elevated risk because of routine use of sharps, and a higher than average incidence of BPIs in the trauma patient population. METHODS: The authors retrospectively reviewed health records of patients admitted to a level 1 trauma center with a facial fracture between January 2010 and December 2015. Patient demographics, medical history, mechanism of injury, type of fracture, and procedures performed were documented. The authors detemined the frequency of human immunodeficiency virus, hepatitis B, and hepatitis C diagnosis and utilized univariable/multivariable analyses to identify risk factors associated with infection in this population. RESULTS: In total, 4608 consecutive patients were included. Infections were found in 4.8% (n = 219) of patients (human immunodeficiency virus 1.6%, hepatitis C 3.3%, hepatitis B 0.8%). 76.3% of BPI patients in this cohort were identified by medical history, while 23.7% were diagnosed by serology following initiation of care. 39.0% of all patients received surgical treatment during initial hospitalization, of whom 4.3% had a diagnosed BPI. History of intravenous drug use (odds ratio [OR] 6.79, P < 0.001), assault-related injury (OR 1.61, P = 0.003), positive toxicology screen (OR 1.56, P = 0.004), and male gender (OR 1.53, P = 0.037) were significantly associated with a BPI diagnosis. CONCLUSION: Patients presenting with facial fractures commonly harbor a BPI. The benefit of early diagnosis and risk to surgical staff may justify routine screening for BPI in high risk facial trauma patients (male, assault-related injury, and history of intravenous drug use).

Differences in Facial Fracture Patterns in Pediatric Nonaccidental Trauma.

BACKGROUND: The purpose of this study was to characterize differences in facial fracture injury patterns among pediatric patients at highest risk of abusive head trauma/nonaccidental trauma (age ≤ 5 years). METHODS: Using the National Trauma Databank from 2007 to 2015, patients (age ≤ 5 years) suffering facial fractures were included. Demographics and injury characteristics were compared between those sustaining accidental versus nonaccidental trauma (NAT). RESULTS: Over 9 years 9741 patients were included with 193 patients (2.0%) suffering NAT. Nonaccidental trauma patients were younger (median [interquartile range]; 0 [0, 2] versus 3 [1, 4], P < 0.001), and more frequently were insured by Medicaid (76.7% versus 41.9%, P < 0.001). NAT patients were more likely to sustain mandible fractures (38.9% versus 21.1%, P < 0.001), but less likely to sustain maxilla (9.8% versus 18.3%, P = 0.003), or orbital fractures (31.1% versus 53.4%, P < 0.001). Nonaccidental trauma patients had fewer instances of multiple facial fracture sites (8.9% versus 22.6%, P < 0.001). Among those sustaining mandible fractures, NAT patients were more likely to sustain condylar fractures (75.8% versus 48.4%, P < 0.001), but less likely to sustain subcondylar fractures (0% versus 13.2%, P = 0.002), or angle fractures (1.6 versus 8.7%, P = 0.048). CONCLUSIONS: Differences exist in facial fracture patterns in accidental versus nonaccidental trauma within the pediatric population at highest risk for abusive head trauma. Specifically, NAT is associated with fractures of the mandibular condyle and involve fewer facial fracture sites. In the appropriate context, presence of these fractures/patterns should increase suspicion for NAT.

Factors influencing the local cure rate of hidradenitis suppurativa following wide local excision.

Wide local excision is the gold standard and only potential curative therapy for recalcitrant hidradenitis suppurativa. However, high recurrence rates persist even post-surgery with little known on the influencing factors for remission. We evaluated the effect of patient, disease, and operative factors on local cure rate of moderate to severe hidradenitis following wide local excision. We performed a retrospective chart review for all patients who had undergone surgical excision of hidradenitis at a university hospital from 2012 to 2018. We identified 79 patients with a total of 220 operative sites. The majority were obese (mean body mass index [BMI] 32.5), female (71%), African-American (84%), and had a mean age of 31 years. A quarter of operative sites experienced a recurrence (n = 56). Patients who achieved remission had a significantly lower number of affected regions than those who experienced a recurrence (2.3 vs 3.6, P = .0023). Additionally, recurrence rate differed significantly between body locations (P = .0440). Smoking, BMI, Hurley grade, closure method, and excision size did not influence local cure rate. Surgical excision remains a worthy management option for hidradenitis patients with three quarters achieving remission after a single operation. Number of affected regions and location of hidradenitis may play a factor in recurrence.

Panniculectomy at the time of living donor renal transplantation: An 8-year experience.

Panniculectomy can be performed as a prophylactic procedure preceding transplantation to enable obese patients to meet criteria for renal transplantation. No literature exists on combined renal transplant and panniculectomy surgery (LRT-PAN). We describe our 8-year experience performing LRT-PAN. A retrospective chart review of all patients who had undergone LRT-PAN from 2010 to 2018 was conducted. Data were collected on patient demographics, allograft survival and function, and postoperative course. Fifty-eight patients underwent LRT-PAN. All grafts survived, with acceptable function at 1 year. Median length of stay was 4 days with a mean operative duration of 363 minutes. The wound complication rate was 24%. Ninety-day readmission rate was 52%, with medical causes as the most common reason for readmission (45%), followed by wound (32%) and graft-related complications (23%). Body mass index, diabetes status, and previous immunosuppression did not influence wound complication rate or readmission (P = .7720, P = .0818, and P = .4830, respectively). Combining living donor renal transplant and panniculectomy using a multidisciplinary team may improve access to transplantation, particularly for the obese and postobese population. This combined approach yielded shorter-than-expected hospital stays and similar wound complication rates, and thus should be considered for patients in whom transplantation might otherwise be withheld on the basis of obesity.

Characterization of Age-Related Injury Patterns and Surgical Treatment of Pediatric Facial Fractures: Analysis of the National Trauma Data Bank.

BACKGROUND: Presentation of pediatric facial fractures varies widely and many injuries are encountered infrequently by most practitioners. This study summarizes injury patterns in a large cohort of facial fractures and their subsequent surgical management. METHODS: Demographic and clinical characteristics of patients 18 years of age or younger admitted between 2009 and 2015 to trauma centers participating in the National Trauma Data Bank were examined. Craniofacial fractures and reconstructive procedures performed at index admission were selected based on ICD-9 and AIS codes. A multivariable analysis was used to determine independent determinants of surgical repair. RESULTS: Out of 60,094 pediatric patients evaluated in the US emergency departments, 48,821 patients were admitted and underwent open treatment (n = 8364; 17.1%) or closed treatment (n = 4244; 8.7%) of facial fractures. Falls were the most common mechanism of injury in infants and toddlers (<2-year-old, 44.4%, P <0.001), while motor vehicle collisions (32.9%, P <0.001) and assault (22.1%, P <0.001) were most commonly seen in adolescents (12-18-year-old). The frequency and odds of repair of facial fractures increased with advancing age, more so with open than closed treatment in adolescents (73.0%) as compared to infants and toddlers (50.3%). Children who sustained mandible fractures are the most likely to require surgical treatment at index-admission (odds ratio = 13.9, 95% confidence interval 13.1-14.8, P <0.001). CONCLUSIONS: Population-based data shows that pediatric fracture patterns and associated early repair vary significantly with age. Patient demographics and hospital characteristics are significant determinants of surgical treatment that should be related to clinical outcomes in future studies.

Contemporary Characterization of Injury Patterns, Initial Management, and Disparities in Treatment of Facial Fractures Using the National Trauma Data Bank.

BACKGROUND: Contemporary description of facial fracture patterns and factors associated with early operative intervention at trauma centers is lacking. The purpose of this study was to characterize injuries and initial treatment patterns of patients suffering from facial fractures. METHODS: Using the National Trauma Databank from 2007 to 2015, patients suffering from facial fractures were included. Demographics, injury characteristics, and outcomes including operative interventions were assessed. RESULTS: Over 9 years, 626,270 patients were included: 74.5% were male, 39.0% suffered traumatic brain injury (TBI), and 23.3% severe noncraniofacial injuries (chest, abdomen, and/or extremity Abbreviated Injury Score ≥3). A total of 537,594 (85.8%) patients were admitted and 184,206 (34.3%) underwent operations for their facial injuries during the index hospitalization. The frequency and patterns of fractures varied by age, sex, race, and mechanism of injury. Operative intervention rates were highest for mandible (63.2%) and lowest for orbit fractures (1.0%). Multiple regression revealed that multiple factors were independently associated with the odds of early fracture repair including: female versus male (odds ratio [95% confidence interval]: 0.96 [0.94-0.98]), age >65 versus <18 years (0.62 [0.59-0.64]), non-white race (0.95 [0.94-0.97]), uninsured versus Medicaid (0.88 [0.86-0.90]), hospital bed size (>600 vs ≤200 beds, 1.67 [1.61-1.73]), TBI (0.70 [0.69-0.71]), and C-spine injury (0.93 [0.90-0.96]). CONCLUSIONS: Facial fractures are common among many demographic cohorts, and multiple patient and injury-specific factors influenced fracture patterns and management. Early operative intervention was highest for mandible fractures and lowest for orbit fractures. Multiple factors including age, sex, insurance status, hospital characteristics, and race/ethnicity were independently associated with early operative intervention, highlighting disparities in care.

Multidetector CT of Midfacial Fractures: Classification Systems, Principles of Reduction, and Common Complications.

The advent of titanium hardware, which provides firm three-dimensional positional control, and the exquisite bone detail afforded by multidetector computed tomography (CT) have spurred the evolution of subunit-specific midfacial fracture management principles. The structural, diagnostic, and therapeutic complexity of the individual midfacial subunits, including the nose, the naso-orbito-ethmoidal region, the internal orbits, the zygomaticomaxillary complex, and the maxillary occlusion-bearing segment, are not adequately reflected in the Le Fort classification system, which provides only a general framework and has become less relevant in contemporary practice. The purpose of this article is to facilitate the involvement of radiologists in the delivery of individualized multidisciplinary care to adults who have sustained blunt trauma and have midfacial fractures by providing a clinically relevant review of the role of multidetector CT in the management of each midfacial subunit. Surgically relevant anatomic structures, search patterns, critical CT findings and their management implications, contemporary classification systems, and common posttraumatic and postoperative complications are emphasized. ©RSNA, 2018.

Contemporary Management of Mandibular Fracture Nonunion-A Retrospective Review and Treatment Algorithm.

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.
