Importance: Since 2005, a total of 50 face transplants have been reported from 18 centers in 11 countries. The overall survival of the grafts has not yet been established., Objective: To assess the survival of the face transplant grafts and evaluate factors potentially influencing it., Design, Setting, and Participants: Data on all the transplants included in this multicenter cohort study were collected at participating transplant centers for updated nonpublished data, supplemented with literature review for nonparticipating centers. Data from 2005 until September 2023, were included. Data were analyzed from November 11, 2005, through September 18, 2023. Patients included the first 50 patients in the world to have received a face transplant., Exposure: Face transplant graft., Main Outcomes and Measures: The primary outcome was the overall survival of the face transplant graft, defined as either transplant loss or patient death. The secondary outcome was the number of acute rejection episodes per year., Results: The 50 transplants were performed on 39 men (81%) and 9 women (19%) with a median age of 35 (range, 19-68) years at the time of the transplant. The median follow-up time was 8.9 (range, 0.2-16.7) years. During the follow-up, 6 transplants were lost with 2 patients retransplanted. There were 10 patients who died, 2 of whom had lost a transplant. The 5- and 10-year survival of the transplants was 85% (SD, 5%) and 74% (SD, 7%), respectively. The sequential number of the transplant in the world was a significant predictor of survival (hazard ratio, 95; 95% CI, 90-100; P < 05). The median number of acute rejection episodes per year was 1.2 (range, 0-5.3) for the transplants that were lost and 0.7 (range, 0-4.6) for the transplants that survived. No correlation with patient and transplant variables was detected for either the transplant survival or the number of rejection episodes., Conclusions and Relevance: In this study, the overall survival of the face transplants is encouraging. These data suggest that the acceptable long-term survival of face transplants makes them a reconstructive option for extensive facial defects.

Objective: Determine if the ideal location of the construct in microtia reconstruction for hemifacial microsomia (HFM) can be more accurately derived from measurements on the cranium., Design: High-resolution computerized tomography (CT) images were analyzed through craniometric linear relationships., Setting: Our tertiary care institution from 2000 to 2021., Patients/participants: Patients diagnosed with HFM and microtia, who had high-resolution craniofacial CT scans, yielding 36 patients accounting for 44 CT scans., Main Outcome Measure(s): First, the integrity of the posterior cranial vault among HFM patients was determined. If proven to be unaffected, it could be used as a reference in the placement of the construct. Second, the position of the ear in relation to the cranium was assessed in healthy age-matched controls. Third, if proven to be useful, the concordance of these cranium-based relationships could be validated among our HFM cohort., Results: The posterior cranial vault is unaffected in HFM ( P > .001). Further, craniometric relationships between the tragus and the Foramen Magnum, as well as between the tragus and the posterior cranium, have been shown to be highly similar and equally precise in predicting tragus position in healthy controls ( P > .001). These relationships held true across all age groups ( P > .001), and importantly among HFM patients, where the mean absolute difference in predicted tragus position never surpassed 1.5 mm., Conclusions: Relationships between the tragus and the cranium may be used as an alternative to distorted facial anatomy or surgeon's experience to assist in pre-operative planning of construct placement in microtia reconstruction for HFM patients., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: To determine the association between burns and hospitalization for mental health disorders up to three decades later., Summary Background Data: Burns are associated with pain, disability, and scarring, but the long-term impact on mental health is unclear., Methods: We analyzed a cohort of 23,726 burn patients aged ≥10 years who were matched to 223,626 controls from Quebec, Canada, between 1989 and 2022. The main exposure was admission for a burn. We followed patients during 3,642,206 person-years of follow-up to identify future hospitalizations for psychiatric disorders, substance use disorders, and suicide attempts. We estimated adjusted hazard ratios (HR) with 95% confidence intervals (CI) for the association between burns and subsequent mental health hospitalization using Cox proportional hazards regression., Results: Burn patients had 1.76 times greater risk of mental health hospitalization over time (95% CI 1.72-1.81), compared with controls. Associations were present regardless of burn site, but were greatest for burns covering ≥50% of the body (HR 3.29, 95% CI 2.61-4.15), third degree burns (HR 2.04, 95% CI 1.94-2.14), and burns requiring skin grafts (HR 2.00, 95% CI 1.90-2.10). Compared with controls, burn patients had more than two times the risk of hospitalization for eating disorders (HR 3.14, 95% CI 2.50-3.95), psychoactive substance use disorders (HR 2.27, 95% CI 2.17-2.39), and suicide attempts (HR 2.42, 95% CI 2.23-2.62). Risks were particularly elevated within 5 years of the burn, but persisted throughout follow-up., Conclusions: Burns are associated with an increased risk of hospitalization for mental health disorders up to 30 years later., Competing Interests: Conflicts of Interest and Source of Funding : GK-A has received a grant from the Quebec Network on Suicide, Mood Disorders and Related Disorders. NA has received a grant (#PJT-191702) from the Canadian Institutes of Health Research, and a grant (#296785) from the Fonds de recherche du Québec-Santé.

Objective: Hepatic artery anastomosis in liver transplantations requires a meticulous technique to minimize the risk of hepatic artery thrombosis (HAT). The microscope helped improve anastomosis techniques in pediatric patients with small caliber vessels. The aim of this review was to compare microsurgical and non-microsurgical techniques on the incidence of HAT in liver transplantations. The secondary objective was to compare HAT incidence between pediatric and adult cohorts and between plastic and transplant surgeons., Methods: A systematic review of the literature using Medline, Embase, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) was conducted on studies involving HAT in liver transplantations with microsurgery. Three reviewers performed a full article review and data extraction for studies meeting the eligibility criteria of the study., Results: Forty-five studies were incorporated in the final analysis. A total of 7346 patients and 7506 liver transplants were included. The mean age was 17 years old with an equivalent distribution between pediatric (51%, n = 3218) and adult patients (49%, n = 3145). A total of 6351 of these transplantations underwent microsurgical repair, against 1157 with non-microsurgical techniques. The overall HAT rate was 4.9%, including 4.2% in the microsurgical group (n = 268) and 8.5% in the non-microsurgical group (n = 98), a statistically significant increase of 4.3%. The occurrence of HAT was 2.6% with a plastic surgeon versus 4.6% with other types of surgeons. When using microsurgical techniques, the HAT rate was 4.2% with living donors versus 7.7% with deceased donors., Conclusions: HAT and subsequent liver transplant failure are lower when microsurgical techniques, living donors, and plastic surgeons with a microsurgical training are involved in the operation., Competing Interests: Declaration of Competing Interest None to declare., (Copyright © 2023 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

There is no consensus regarding implant size as an independent risk factor for complications in primary breast augmentation. Choosing appropriate implant volume is an integral part of the preoperative planning process. The current study aims to assess the relationship between implant size and the development of complications following augmentation mammaplasty., Methods: A retrospective chart review of patients undergoing primary breast augmentation at the Westmount Institute of Plastic Surgery between January 2000 and December 2021 was conducted. Demographics, implant characteristics, surgical technique, postoperative complications, and follow-up times were recorded. Univariate logistic regression was used to identify independent predictors, which were then included in multivariate logistic regressions of implant volume and implant volume/body mass index (BMI) ratio regarding complications., Results: A total of 1017 patients (2034 breasts) were included in this study. The average implant volume used was 321.4 ± 57.5 cm 3 (range: 110-605). Increased volume and volume/BMI ratio were associated with a significant increase in risk of implant rupture (odds ratio = 1.012, P < 0.001 and 1.282, P < 0.001 respectively). Rates of asymmetry were significantly associated with increases in implant volume and volume/BMI ratio (odds ratio = 1.005, P = 0.004 and 1.151, P < 0.001, respectively). No single implant volume or volume/BMI ratio above which risks of complications significantly increase was identified., Conclusions: Implant rupture and postoperative asymmetries are positively correlated with bigger implant volumes. Implant size could likely be a useful independent predictor of certain complications, especially in patients with high implant to BMI ratios., (Copyright © 2023 The Authors.

Facial vascularized composite allotransplantation (VCA) offers an added layer of complexity when compared to solid organ transplantation. VCAs must account for aesthetic variables such as skin tone and color. The goal of this study is to validate the Nix Color Sensor as a novel tool to be added to the plastic surgeon's armamentarium for evaluating skin color match of the donor and recipient., Methods: A prospective study of 100 individuals was conducted. All participants were photographed and scanned with the Nix Color Sensor. Sixty pairwise comparisons were randomly generated. Skin color analysis was performed using photographs and the Nix Color Sensor. Delta E2000 values were compared to mean evaluator ratings using a Spearman correlation analysis., Results: One hundred patients were included. A Spearman's correlation demonstrated a strong inverse correlation between Delta E2000 values and the mean evaluator ratings. The higher the mean evaluator rating for likeness, the lower the delta. A correlation coefficient of -0.850 demonstrates a statistically significant relationship ( P < 0.01)., Conclusions: When the Delta E2000 rises above 5 there is a significant drop in the mean evaluator ratings. As mean evaluator ratings of 5 and above would be considered adequate for face transplant amongst most plastic surgeons, an E2000 value of 5 or lower should be targeted when matching donors with recipients for face transplant. The Nix Color Sensor positively correlates to the plastic surgeon's perception of skin color and can serve as an adjunct in donor selection for facial VCAs., (Copyright © 2022 The Authors.

Background: Hemifacial microsomia (HFM) is one of the most common congenital craniofacial disorders. Among many other features, microtia is present in the large majority of these patients. However, mainly due to the unilateral hypoplastic anatomy, microtia reconstruction among this patient population remains a reconstructive challenge for plastic surgeons. Given that no clear standards exist, an evidence-based synthesis of the literature was devised., Methods: A systematic search of Pubmed, Medline, and Embase was carried out, in accordance with the PRISMA guidelines. Studies discussing surgical microtia reconstruction for HFM patients were retained. Qualitative data regarding study design, challenges addressed, specific recommendations, and their respective strengths/limitations were extracted from each. Retrieved recommendations were consolidated and assigned a level of evidence grade., Results: Although only 11 studies were included in this review, these provided 22 main recommendations regarding the eight HFM-specific challenges identified, which were of either grade C (n = 5) or D (n = 17). Included studies addressed construct location (n = 7), the low hairline (n = 6), soft tissue construct coverage (n = 6), earlobe reconstruction (n = 6), construct projection (n = 5), anomalies of the relevant neurovascular systems (n = 2), retroauricular construct coverage (n = 2), and sizing of the construct (n = 2)., Conclusions: Given the many persisting reconstructive challenges regarding surgical microtia reconstruction for HFM patients, the authors present a comprehensive and evidence-based consolidation of recommendations specific to these challenges. The authors hope this systematic review can appropriately guide plastic surgeons and will ultimately improve care for this patient population., (Copyright © 2022 The Authors.

Background: The intercanthal distance (ICD) is central to our perception of facial proportions, and it varies according to gender and ethnicity. Current standardized reference values do not reflect the diversity among patients. Therefore, the authors sought to provide an evidence-based and gender/ethnicity-specific reference when evaluating patients' ICD., Methods: As per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic search of PubMed, Medline, and Embase was carried out for studies reporting on the ICD. Demographics, study characteristics, and ICDs were extracted from included studies. ICD values were then pooled for each ethnicity and stratified by gender. The difference between men and women, and that across ethnicities and measurement types were compared by means of independent sample t -test and one-way ANOVA (SPSS v.24)., Results: A total of 67 studies accounting for 22,638 patients and 118 ethnic cohorts were included in this pooled analysis. The most reported ethnicities were Middle Eastern (n = 6629) and Asian (n = 5473). ICD values (mm) in decreasing order were: African 38.5 ± 3.2, Asian 36.4 ± 1.6, Southeast Asian 32.8 ± 2.0, Hispanic 32.3 ± 2.0, White 31.4 ± 2.5, and Middle Eastern 31.2 ± 1.5. A statistically significant difference ( P < 0.05) existed between all ethnic cohorts, between genders among most cohorts, and between most values stratified by measurement type., Conclusions: Our standards of craniofacial anthropometry must evolve from the neoclassical canons using White values as references. The values provided in this review can aid surgeons in appreciating the gender- and ethnic-specific differences in the ICD of their patients., (Copyright © 2022 The Authors.

Learning Objectives: After studying this article, the participant should be able to: 1. Identify common negative outcomes that arise with conventional nasal reconstruction. 2. Understand the technical refinements that help avoid and reduce negative outcomes in nasal reconstruction. 3. Learn about the utility of regional axial island flaps for nasal reconstruction, in particular, the lateral nasal artery flap., Summary: Nasal reconstruction has been a preoccupation of surgeons dating to before 600 bc. The nose is the central focal point of the face and a key identifying facial feature, and surgery to the nose can prove to be challenging to even the most experienced surgeon. The objective of this CME article is to outline the most commonly used surgical options for each nasal aesthetic subunit, and the specific complications observed for each. The best surgical options and technical refinements are highlighted, and principles that may help restore the nose are outlined., Competing Interests: Disclosure:The authors have no conflicts of interest to declare., (Copyright © 2021 by the American Society of Plastic Surgeons.)

Introduction: Congenital aneurysms of major arteries are very rare diagnoses and prognosis can be poor if treatment is not initiated rapidly. This is the presentation of two cases of infants with congenital iliac aneurysms who underwent treatment in the neonatal period. The report then proceeds with a literature review of paediatric iliac aneurysms., Report: Case 1: A female neonate was diagnosed antenatally with right common iliac (CIA) and internal iliac (IIA) artery aneurysms. Embolisation on day of life (DOL) eight was impossible because of partial thrombosis. The infant was subsequently observed for several months and the aneurysm was injected percutaneously with thrombin on DOL 78. A small residual aneurysm was coil embolised at five months of age. Satisfactory results were observed at one year follow up. Case 2: A female neonate was diagnosed antenatally on routine third trimester ultrasound with voluminous, bilateral CIA aneurysms. The patient underwent surgery on DOL 9 for aneurysm resection and microsurgical vascular reconstruction. The intervention was successful with triphasic flow through the anastomoses on colour Doppler ultrasound at six week follow up., Discussion: Ten cases of congenital iliac aneurysms have been reported previously, with just two diagnosed in the neonatal period and eight undergoing surgical intervention. Definitive management to avoid aneurysm rupture or thrombosis should be timed carefully, and sometimes delayed with watchful waiting, to maximise success and minimise complications. Surgery is the key treatment modality, but endovascular intervention can be considered in selected cases. Congenital iliac aneurysms should be addressed at the safest time for the patient. Following resection, primary microvascular anastomosis is the ideal reconstructive technique, but other options for neonates have been described. Endovascular treatment should be considered for anatomically amenable saccular aneurysms., (© 2021 Published by Elsevier Ltd on behalf of European Society for Vascular Surgery.)

In 2005, the first facial vascularized composite allotransplant was performed in France. In May 2018, our team at Maisonneuve-Rosemont Hospital, Montreal, Quebec, had the privilege to participate in the first facial transplant in Canada. Interdisciplinary collaboration, coordination, and communication formed the cornerstone of this medical undertaking and, ultimately, its success. This report details the anesthetic and organizational considerations of our experience.

Facial transplantation (FT) is recognized as the ultimate reconstruction for severely disfigured patients. The substantial cost of these procedures in a nationalized health system has not been extensively published. The first Canadian FT performed in May 2018 was a great opportunity to address this subject and evaluate the viability of such a program., Methods: A detailed patient chart review was performed and a cost per unit approach was used to estimate the procedure cost. The preoperative, operative, and the postoperative periods up to 1-year after the surgery were analyzed. Financial support from private sponsors and Hospital Fund donations were considered. The literature on international FT and national solid organ transplantation was reviewed., Results: The overall 1-year cost was estimated at $440,224 (2018 CAD). The costs are explained by a long hospital length of stay, costly immunosuppressive therapy, and high immunosuppression-related complications. Those findings are consistent with international FT literature. The societal impact of the surgery was minimized with a $36,921 (2018 CAD) grant obtained from an external contributor. Interestingly, the hospital foundation sustained a 794% increase in donations ($1,787,148; 2019 CAD) the year following the surgery., Conclusion: Our experience confirmed that the combination of private funding, with positive goodwill and hospital donations, is a workable model for innovative surgery in the setting of a nationalized health system with financial restrictions., (Copyright © 2021 The Authors.

Our objective was to determine the potential impact of the surgical treatment of ameloblastoma in children through validated health state utility outcome measures., Methods: A survey-based preference health utility assessment using the visual analog scale, time trade-off, and standard gamble methods was undertaken among a general population sample. Quality-adjusted life years were derived from these measures. A one-way ANOVA was used for statistical analysis, with a mean ( P ) value of 0.05 considered significant. Demographic parameters were individually assessed as possible predictors of each utility score., Results: In total, 86 participants took part in this study, with a mean age of 29.9 years. Greater utility scores were observed among participants reporting no religious beliefs ( P = 0.025, t = 2.28). No other demographic parameters showed statistically significant prediction of utility score. From the mean utility scores (± SD) (visual analog scale = 0.60 ± 0.17; time trade-off = 0.65 ± 0.22; standard gamble = 0.64 ± 0.20), a gain of 30.0, 32.3, and 32.1 quality-adjusted life years may be derived, respectively. All utility outcome measures suggested that an ameloblastoma during childhood is perceived as more burdensome than several debilitating conditions, such as cleft lip and palate., Conclusions: To attain perfect health, participants would theoretically undergo surgical treatment of an ameloblastoma during childhood, with willingness to trade off 28.2 years of life and accepting a 35.7% risk of death. The objective assessment of the perceived burden of an ameloblastoma affliction during childhood may inspire cost-utility or cost-effectiveness analyses at broader societal levels., (Copyright © 2021 The Authors.

The effects of maxillary advancement on velopharyngeal anatomy have primarily been studied using lateral cephalometric radiographs. However, with recent advances in orthognathic surgery, there is an increased need for more detailed and precise imaging such as computerized tomographic (CT) scan reconstructions, to help in surgical planning and to measure outcomes. The purpose of this study was to compare the pre- and post-operative velopharyngeal anatomic configuration modifications as measured on CT scans., Methods: This is a retrospective cohort study of 44 patients with and without cleft palate who were treated with maxillary advancement. The pre- and post-operative CT scans were compared with respect to pre-established landmarks. Linear distances, cross-sectional areas, and volumes were measured using 3-dimensional CT scan reconstructions., Results: For the linear distances measured, a statistically significant difference was found when comparing the pre- and post-operative measures of the narrowest part of the nasopharynx and the narrowest part of the retropalatal airway space ( P = 0.001 and 0.026, respectively). Retropalatal cross-sectional areas, nasopharyngeal cross-sectional areas, and the volumetric assessment of the nasopharyngeal space showed no statistically significant differences when comparing pre- and post-operative scans ( P < 0.05). Mean changes in the measures did not differ over time (pre- and post-operative) depending on whether there was a prior history of cleft palate repair., Conclusions: Although structural modifications of the pharyngeal space are inherent to maxillary advancement, its surface area and volume do not significantly change. The use of 3-dimensional reconstruction using CT scans should be the first choice for evaluation of the upper airway., (Copyright © 2020 The Authors.

Background: Histologic criteria for diagnosing acute rejection in vascularized composite tissue allograft (VCA) have been established by the Banff 2007 Working Classification of Skin-Containing Composite Tissue Allograft, but the role of early vascular lesions in graft rejection warrants additional analysis., Methods: We performed a retrospective study of 34 skin biopsies performed over 430 d for rejection surveillance, in Canada's first face allotransplant recipient. Three observers reviewed all biopsies to assess the nature and intensity of the inflammatory skin infiltrate. A complete histological and immunohistochemical review of the vascular components was performed with a focus on lymphocytic vasculitis, intravascular fibrin, vessel caliber, extent of injury, C4d positivity, and inflammatory cell phenotyping. We then correlated these data points to clinical and immunosuppression parameters., Results: Acute vascular damage in biopsies that would be classified as mild acute rejection correlates with troughs in immunosuppression and subsides when immunosuppressive tacrolimus doses are increased. Grade 0 Banff rejection and Grade I without lymphocytic vasculitis were almost indistinguishable, whereas Grade I with lymphocytic vasculitis was an easy and reproducible histologic finding., Conclusions: Our results highlight the possible relevance of vascular injury in the context of VCA, as its presence might underlie a more aggressive form of immune rejection. If these findings are validated in other VCA patients, vascular injury in mild rejection might warrant a different clinical approach.

Introduction: Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare and recently described type of peripheral T-cell lymphoma. Fewer than 550 cases have been reported worldwide. Although BIA-ALCL is usually indolent, early diagnosis and treatment have been shown to improve outcome., Case Description: This case report describes the management of a 50-year-old healthy Caucasian woman presenting with rapid painful enlargement of the left breast. Imaging revealed findings consistent with BIA-ALCL. This diagnosis was confirmed by fine needle aspiration cytology and subsequent pathological analysis. Bilateral removal of implants, complete left capsulectomy and immediate bilateral implant exchange were performed., Conclusion: No consensus currently exists regarding optimal time of implant exchange and management of the contralateral capsule. The immediate replacement with smooth implants was thoroughly discussed with the patient and endorsed by expert opinion, given complete removal of the disease. There was no sign of recurrence at 6 months. Close clinical and radiological visits are planned for the next years., Level of Evidence V: This journal requires that authors assign a level of evidence to each article.

Background: Areas of surgical care in which, traditionally, plastic surgeons were exclusively involved are now routinely offered by other surgical specialists. Whether this shift in clinical responsibilities influenced publication rates of plastic surgeons remains unknown. The current article investigates the proportion of contributions in plastic surgery journals originating from authors with a plastic surgery background as well as publication rates and author demographics., Methods: A cross-sectional sample study of every publication originating from Annals of Plastic Surgery, Journal of Plastic, Reconstructive and Aesthetic Surgery, and Plastic and Reconstructive Surgery was performed for 2006 and 2016. Data about the articles' methodological design and branch of plastic surgery as well as authors' country of origin, educational degree and specialty training were analyzed., Results: From 1721 publications included, head and neck reconstruction was the branch of plastic surgery with the highest number of publications at 18% and most articles (30%) were retrospective cohort studies. From 3381 authors analyzed, a significant proportion originated from United States (34%). More than 85% of authors were physicians as opposed to other health care professionals. The specialty with the highest representation was plastic surgery at 72%, but the proportion decreased in all 3 journals by a mean rate of 3.8% in 2016., Conclusions: A slight decrease in publication rates from plastic surgeons occurred in Annals of Plastic Surgery, Journal of Plastic, Reconstructive and Aesthetic Surgery, and Plastic and Reconstructive Surgery from 2006 to 2016. Publications rates and author characteristics in plastic surgery journals provide valuable insight on plastic surgeons' contribution to contemporary scientific literature.

Objective: Over the past few years, virtual surgical planning (VSP) has evolved into a useful tool for the craniofacial surgeon. Virtual planning and computer-aided design and manufacturing (CAD/CAM) may assist in orthognathic, cranio-orbital, traumatic, and microsurgery of the craniofacial skeleton. Despite its increasing popularity, little emphasis has been placed on the learning curve., Methods: A retrospective analysis of consecutive virtual surgeries was done from July 2012 to October 2016 at the University of Montreal Teaching Hospitals. Orthognathic surgeries and free vascularized bone flap surgeries were included in the analysis., Results: Fifty-four virtual surgeries were done in the time period analyzed. Forty-six orthognathic surgeries and 8 free bone transfers were done. An analysis of errors was done. Eighty-five percentage of the orthognathic virtual plans were adhered to completely, 4% of the plans were abandoned, and 11% were partially adhered to. Seventy-five percentage of the virtual surgeries for free tissue transfers were adhered to, whereas 25% were partially adhered to. The reasons for abandoning the plans were (1) poor communication between surgeon and engineer, (2) poor appreciation for condyle placement on preoperative scans, (3) soft-tissue impedance to bony movement, (4) rapid tumor progression, (5) poor preoperative assessment of anatomy., Conclusion: Virtual surgical planning is a useful tool for craniofacial surgery but has inherent issues that the surgeon must be aware of. With time and experience, these surgical plans can be used as powerful adjuvants to good clinical judgement.

Background: We have adopted an intraoral microsurgical anastomosis to the facial vessels to eliminate the need for any visible facial incisions., Methods: Cadaveric dissection was used to demonstrate accessibility of the facial artery and vein through an intraoral approach. Additionally, 5 patients underwent free tissue transfer for reconstruction of major defects of the midface through an intraoral, transmucosal approach, obviating the need for visible skin incisions., Results: The pathology included palatal defects due to mucoepidermoid carcinoma and ischemic necrosis from cocaine abuse, maxillary defects secondary to fibrous dysplasia and avascular necrosis from traumatic blast injury, and a residual posttraumatic bony deformity of the zygoma. Reconstructions were performed with a free ulnar forearm flap, a free vastus lateralis muscle flap, a deep circumflex iliac artery myoosseous flap, a free fibula flap, and a deep circumflex iliac artery osseous flap, respectively. The facial artery and vein were used as recipient vessels for microvascular anastomosis for all cases. Mean follow-up was 12.2 months. All free tissue transfers were successful, and each patient had a satisfactory aesthetic outcome with no associated facial scars., Conclusion: This technique can be employed during reconstruction of an array of bony or soft-tissue midface deficits with minimal morbidity. This small series effectively demonstrates the varied pathologies and tissue deficiencies that can be successfully reconstructed with free tissue transfer using an entirely intraoral approach to the recipient facial vessels, resulting in no visible scars on the face and an improvement in the overall aesthetic outcome.

Efficacy of prophylactic antibiotics in craniofacial fracture management is controversial. The purpose of this study was to compare evidence-based literature recommendations regarding antibiotic prophylaxis in facial fracture management with expert-based practice. A systematic review of the literature was performed to identify published studies evaluating pre-, peri-, and postoperative efficacy of antibiotics in facial fracture management by facial third. Study level of evidence was assessed according to the American Society of Plastic Surgery criteria, and graded practice recommendations were made based on these assessments. Expert opinions were garnered during the Advanced Orbital Surgery Symposium in the form of surveys evaluating senior surgeon clinical antibiotic prescribing practices by time point and facial third. A total of 44 studies addressing antibiotic prophylaxis and facial fracture management were identified. Overall, studies were of poor quality, precluding formal quantitative analysis. Studies supported the use of perioperative antibiotics in all facial thirds, and preoperative antibiotics in comminuted mandible fractures. Postoperative antibiotics were not supported in any facial third. Survey respondents (n = 17) cumulatively reported their antibiotic prescribing practices over 286 practice years and 24,012 facial fracture cases. Percentages of prescribers administering pre-, intra-, and postoperative antibiotics, respectively, by facial third were as follows: upper face 47.1, 94.1, 70.6; midface 47.1, 100, 70.6%; and mandible 68.8, 94.1, 64.7%. Preoperative but not postoperative antibiotic use is recommended for comminuted mandible fractures. Frequent use of pre- and postoperative antibiotics in upper and midface fractures is not supported by literature recommendations, but with low-level evidence. Higher level studies may better guide clinical antibiotic prescribing practices.

In preparation for the donor and recipient facial vascularized composite allotransplant (VCA), the marginal mandibular nerve branch should be identified and co-apted to the recipient's nerve to allow for re-innervation. We describe a method to identify the marginal mandibular branch of the facial nerve in facial VCA donors and recipients. Through cadaver dissections, the posterior facial vein was traced posteriorly to identify the marginal mandibular branch of the facial nerve. In cases where we were unable to use this relationship, we found the posterior facial venous system to be diminutive. This technique is useful for finding the marginal mandibular branch when dissecting anterograde to the parotid gland.

Background: As of July of 2013, 27 facial vascularized composite allotransplantations have been performed. The authors developed a classification system and treatment algorithm that is practical and surgically applicable., Methods: The majority of the transplants have been described in the surgical literature and the media, and a review of the data was performed. A classification system and a treatment algorithm were designed. Skeletal defects were defined by craniofacial osteotomies and soft-tissue defects by aesthetic facial subunits. The soft-tissue defect was subdivided into the following subunits: oral-nasal (type 1), oronasal-orbital (type 2), and full facial (type 3). The bony defects were subdivided into mandibular involvement (M), Le Fort 1 (A), Le Fort 3 (B), and monobloc (C)., Results: The mechanisms of injury included trauma (n = 13), burns (n = 8), congenital deformity (n = 3), oncologic resection (n = 1), and unreported (n = 2). According to the proposed classification system: one was type 1; one was type 1-M; one was type 1-MB; two were type 2; two were type 2-B; two were type 2-MB; six were type 3; one was type 3-B; and three were type 3-MB; eight could not be classified due to a lack of data. The treatment algorithm designed a vascularized composite allotransplantation that addressed the bony and soft-tissue components., Conclusions: Patient selection for these complicated procedures, currently dependent on lifelong immunosuppression, is crucial to their success. The authors describe a classification system and treatment algorithm for facial defects that may be ideally suited for facial transplantation. The proposed classification and algorithm may help centers define indications and ideally improve patient outcomes., Clinical Question/level of Evidence: Therapeutic, V.

Background: Considerable operative time is expended during the planning, shaping, and reconfiguring of the cranial vault in the pursuit of symmetry during open craniosynostosis surgery. Computer-aided design and manufacturing has recently been implemented in orthognathic surgery and complex craniomaxillofacial reconstruction as a means of optimizing operative accuracy and efficiency. In this report, we highlight our growing experience with this promising modality for the preoperative planning and intraoperative execution of cranial vault remodeling in patients with both simple and complex forms of craniosynostosis., Methods: Computer-assisted surgical planning begins with acquisition of high-resolution computed tomography scans of the craniofacial skeleton. An Internet-based teleconference is then held between the craniofacial and biomedical engineering teams and provides a forum for virtual manipulation of the patient's preoperative three-dimensional computed tomography with real-time changes and feedback. Through virtual surgical planning, osteotomies are designed and calvarial bones reconfigured to achieve the desired cranial vault appearance. Cutting and positioning guides are manufactured to transform the virtual plan into a reality., Results: From February to March 2012, 4 children (aged 9 months to 6 years) with craniosynostosis underwent computer-assisted simulation and surgery. Diagnoses included metopic, unicoronal (n = 2), and multisutural synostoses (sagittal and left unicoronal). Open craniofacial repairs were performed as virtually planned, including front o-orbital remodeling, fronto-orbital advancement, and anterior two-thirds calvarial remodeling, respectively. Cutting and final positioning guides demonstrated excellent fidelity and ease of use., Conclusions: Computer-aided design and manufacturing may offer a platform for optimizing operative efficiency, precision, and accuracy in craniosynostosis surgery, while accelerating the learning curve for future trainees.

Background: The central face high-energy avulsive injury has been frequently encountered and predictably managed at the R Adams Cowley Shock Trauma Center. However, despite significant surgical advances and multiple surgical procedures, the ultimate outcome continues to reveal an inanimate, insensate, and suboptimal aesthetic result., Methods: To effectively address this challenging deformity, a comprehensive multidisciplinary approach was devised. The strategy involved the foundation of a basic science laboratory, the cultivation of a supportive institutional clinical environment, the innovative application of technologies, cadaveric simulations, a real-time clinical rehearsal, and an informed and willing recipient who had the characteristic deformity., Results: After institutional review board and organ procurement organization approval, a total face, double jaw, and tongue transplantation was performed on a 37-year-old man with a central face high-energy avulsive ballistic injury., Conclusions: This facial transplant represents the most comprehensive transplant performed to date. Through a systematic approach and clinical adherence to fundamental principles of aesthetic surgery, craniofacial surgery, and microsurgery and the innovative application of technologies, restoration of human appearance and function for individuals with a devastating composite disfigurement is now a reality., Clinical Question/level of Evidence: Therapeutic, V.

Background: The anatomy of the facial nerve and its branches has been well documented. The course of the extratemporal facial nerve, its anatomical planes, and the surface landmarks of the temporal division and marginal mandibular division are well known. However, the surface landmark of the middle division of the facial nerve has not been studied to date., Methods: Eighteen hemifacial dissections in 10 fresh human cadavers were performed through a preauricular face-lift incision. An 18-gauge needle with brilliant green dye was used to mark the nerve through the skin before dissection. The exact location of the middle division branches of the facial nerve was documented in relation to the transcutaneous marking., Results: The middle division branches of the facial nerve were found to lie at a mean of 2.3 mm from the tattooed point, with a range of 0 to 6 mm. A nerve branch was found directly tattooed by the needle seven of 18 times, inferior to the tattoo five of 18 times, and superior to the tattoo six of 18 times., Conclusions: The zygomatic/buccal motor branch that innervates the zygomaticus major muscle can be reliably found at the midway point on a line drawn from the root of the helix and the lateral commissure of the mouth. This study will help guide surgeons to the middle division of the facial nerve as it applies to facial surgery.

Background: Reconstructing periorbital defects is challenging because of the simultaneous need for ocular support, corneal protection, and restoration of aesthetic subtleties. In patients with extensive periorbital tissue loss, microvascular free tissue transfer is a reliable reconstructive option for composite defects., Methods: The authors conducted a retrospective review of patients with periorbital craniofacial defects and identified those treated with microvascular reconstruction at the R Adams Cowley Shock Trauma Center and The Johns Hopkins Hospital from 2001 to 2010., Results: Twenty-four patients underwent free flap reconstruction for periorbital defects secondary to trauma (n = 12), oncologic resection (n = 11), and congenital deformity (n = 1). The majority were men (n = 13), and the average age of the patients was 47 years (range, 19 to 80 years). Microvascular reconstructions included fibula (n = 9), anterolateral thigh (n = 6), ulnar forearm (n = 7), and groin flaps (n = 2). Flap survival rate was 100 percent, with an average follow-up of 26.5 months., Conclusions: Microvascular reconstruction of the periorbit can be accomplished successfully through careful analysis of tissue loss, eye or ocular prosthetic support, donor-site morbidity, and patient preference. Despite the multiple flap options that fulfill periorbital reconstructive needs, the authors find that the fibula, anterolateral thigh, ulnar forearm, and groin flaps can be used reliably to successfully reconstruct these defects., Clinical Question/level of Evidence: Therapeutic, IV.

Mandibular trauma is a common problem encountered by the craniofacial surgeon. Fractures in the edentulous mandible represent only 3% of these injuries, and optimal management is controversial. This problem is further compounded by malunion and malocclusion when fracture lines heal in incorrect positions. Even with recent advances in imaging and hardware systems, they remain difficult problems that often require multiple operations to obtain satisfactory results. We present a 69-year-old man with an edentulous mandibular fracture and concomitant malocclusion after a series of unsuccessful operations. By using computer-assisted design and manufacturing technology, we were able to plan osteotomies for correct anatomic positioning, which restored dental occlusion and facial aesthetics. A follow-up at 6 months postoperatively revealed a stable and anatomic reconstruction.

Background: With the transplantation of more extensive facial vascularized composite allografts, fundamental craniofacial and aesthetic principles become increasingly important. In addition, computer-assisted planning and intraoperative navigation may improve precision and efficiency in these complex procedures., Methods: Ten mock face transplants were performed in 20 cadavers. The vascularized composite allograft consisted of all facial skin, mimetic muscles, the tongue, the midface by means of a Le Fort III osteotomy, and the mandible by means of sagittal split osteotomies. Craniofacial computed tomographic scans were obtained before and after the mock transplants. Surgical planning software was used to virtually plan the osteotomies, and a surgical navigation system guided the osteotomies intraoperatively. Cephalometric analyses were compared between the virtually planned transplants and the actual postoperative results., Results: The combination of preoperative computerized planning and intraoperative guidance consistently produced a vascularized composite allograft that could be easily fixated to the prepared recipient, with only minimal burring of osteotomy sites necessary. Satisfactory occlusion was maintained, and postoperative computed tomography confirmed accurate skeletal fixation. Insignificant differences with regard to cephalometric analyses were noted when predicted and actual postoperative data were compared., Conclusions: The authors' experience treating severe craniofacial injury allowed consistent transfer of facial vascularized composite allografts, maintaining proper occlusion. Preoperative computer planning and intraoperative navigation ensured precise osteotomies and a good donor-recipient skeletal match, which greatly reduced the need for intraoperative adjustments and manipulation. This total facial vascularized composite allograft represents one of the most extensive described and is intended to represent a typical central facial demolition pattern.

Background: Transplantation of a facial vascularized composite allograft is a highly complex procedure that requires meticulous planning and affords little room for error. Although cadaveric dissections are an essential preparatory exercise, they cannot simulate the true clinical experience of facial vascularized composite allograft recovery., Methods: After obtaining institutional review board approval to perform a facial vascularized composite allograft research procurement, a 66-year-old, brain-dead donor was identified. The family graciously consented to donation of a total face, double jaw, and tongue allograft and multiple solid organs., Results: A craniofacial computed tomographic angiogram was obtained preoperatively to define the vascular anatomy and facilitate virtual computerized surgical planning. The allograft was procured in 10 hours, with an additional 2 hours required for an open tracheostomy and silicone facial impression. The donor was coagulopathic throughout the recovery, resulting in an estimated blood loss of 1500 ml. Fluorescence angiography confirmed adequate perfusion of the entire allograft based on lingual and facial arterial and external jugular and thyrolinguofacial venous pedicles. The solid organ transplant team initiated abdominal organ isolation while the facial allograft procurement was in progress. After completion of allograft recovery, the kidneys and liver were recovered without complication., Conclusions: Before conducting a clinical face transplant, adequate preparation is critical to maximize vascularized composite allotransplantation outcomes and preserve solid organ allograft function. As more centers begin to perform facial transplantation, research procurement of a facial vascularized composite allograft offers a unique educational opportunity for the surgical and anesthesia teams, the organ procurement organization, and the institution.

Objective: The purpose of this study was to evaluate subperiosteal release of the floor of the mouth (SRFM) musculature to correct neonatal airway obstruction in children with Pierre Robin sequence and to compare this procedure with other surgical options available., Methods: A retrospective chart review of patients who underwent a SRFM for neonatal severe airway obstruction unresponsive to conservative management was performed. Preoperative and postoperative oxygenation parameters, sleep studies, feeding difficulties, and long-term evolution were documented., Results: Thirty-one consecutive patients between 1995 and 2009, 19 boys and 12 girls, had an SRFM procedure to alleviate severe neonatal airway obstruction. Eight children were syndromic, 15 had associated malformations, and eight had an isolated Pierre Robin sequence. The airway obstruction was corrected with SRFM alone in 26 children (84%), three patients remained dependent on nasopharyngeal airway, and two required subsequent mandibular osteogenic distraction procedures following the SRFM to manage persistent obstruction. No patient required a tracheostomy. The average age at SRFM was 33 days, and the patients were kept intubated for an average of 6 days postoperatively. Average hospital stay after the surgery was 45 days, and 10 patients went home with gavage feeding., Conclusions: The SRFM is effective for the treatment of severe airway obstruction in patients with Pierre Robin sequence. The procedure is simple and has fewer complications and secondary procedures than other surgical options for correction of the airway obstruction.
