The objective of this study was to develop guidelines for the transfer of patients with isolated craniomaxillofacial trauma.A national, multidisciplinary expert panel was assembled from leadership in national organizations and contributors to published literature on facial reconstruction. The final panel consisted of five plastic surgeons, four otolaryngologist-head and neck surgeons, and four oral and maxillofacial surgeons. The expert panelists' opinions on transfer guidelines were collected using the modified Delphi process. Consensus was predefined as 90 percent or greater agreement per statement.After four Delphi consensus building rounds, 13 transfer guidelines were established, including statements on fractures of the frontal sinus, orbit, midface, and mandible, as well as soft-tissue injuries. Twelve guidelines reached consensus.The decision to transfer a patient with craniomaxillofacial trauma to another facility is complex and multifactorial. While a percentage of overtriage is acceptable to promote safe disposition of trauma patients, unnecessarily high rates of secondary overtriage divert emergency medical services, increase costs, delay care, overload tertiary trauma centers, and result in tertiary hospital staff providing primary emergency coverage for referring hospitals. These craniomaxillofacial transfer guidelines were designed to serve as a tool to improve and streamline the care of facial trauma patients. Such efforts may decrease the additional health care expenditures associated with secondary overtriage while decompressing emergency medical systems and tertiary emergency departments.

Vascularized composite allotransplantation has redefined the frontiers of plastic and reconstructive surgery. At the cutting edge of this evolving paradigm, the authors present the first successful combined full face and bilateral hand transplant.A 21-year-old man presented for evaluation with sequelae of an 80 percent total body surface area burn injury sustained after a motor vehicle accident. The injury included full face and bilateral upper extremity composite tissue defects, resulting in reduced quality of life and loss of independence. Multidisciplinary evaluation confirmed eligibility for combined face and bilateral hand transplantation. The operative approach was validated through 11 cadaveric rehearsals utilizing computerized surgical planning. Institutional review board and organ procurement organization approvals were obtained. The recipient, his caregiver, and the donor family consented to the procedure.Combined full face (i.e., eyelids, ears, nose, lips, and skeletal subunits) and bilateral hand transplantation (i.e., forearm level) was performed over 23 hours on August 12 to 13, 2020. Triple induction and maintenance immunosuppressive therapy and infection prophylaxis were administered. Plasmapheresis was necessary postoperatively. Minor revisions were performed over seven subsequent operations, including five left upper extremity, seven right upper extremity, and seven facial secondary procedures. At 8 months, the patient was approaching functional independence and remained free of acute rejection. He had significantly improved range of motion, motor power, and sensation of the face and hand allografts.Combined face and bilateral hand transplantation is feasible. This was the most comprehensive vascularized composite allotransplantation procedure successfully performed to date, marking a new milestone in plastic and reconstructive surgery for patients with otherwise irremediable injuries.

Defects involving the midface and maxilla pose unique challenges to reconstructive surgeons. The maxilla serves as the central keystone of the face and interfaces with various other facial subunits to affect form and function. Reconstructive methods range from prosthetics to free tissue transfer, and the indications for different options are reviewed here. Finally, special considerations including management of the orbit, dental rehabilitation, and future directions are discussed.

SUMMARY: The coronavirus disease of 2019 pandemic became a global threat in a matter of weeks, with its future implications yet to be defined. New York City was swiftly declared the epicenter of the pandemic in the United States as case numbers grew exponentially in a matter of days, quickly threatening to overwhelm the capacity of the health care system. This burgeoning crisis led practitioners across specialties to adapt and mobilize rapidly. Plastic surgeons and trainees within the New York University Langone Health system faced uncertainty in terms of future practice, in addition to immediate and long-term effects on undergraduate and graduate medical education. The administration remained vigilant and adaptive, enacting departmental policies prioritizing safety and productivity, with early deployment of faculty for clinical support at the front lines. The authors anticipate that this pandemic will have far-reaching effects on the future of plastic surgery education, trends in the pursuit of elective surgical procedures, and considerable consequences for certain research endeavors. Undoubtedly, there will be substantial impact on the physical and mental well-being of health care practitioners across specialties. Coordinated efforts and clear lines of communication between the Department of Plastic Surgery and its faculty and trainees allowed a concerted effort toward the immediate challenge of tempering the spread of coronavirus disease of 2019 and preserving structure and throughput for education and research. Adaptation and creativity have ultimately allowed for early rebooting of in-person clinical and surgical practice. The authors present their coordinated efforts and lessons gleaned from their experience to inform their community's preparedness as this formidable challenge evolves.

Background:Facial transplantation introduced a paradigm shift in the reconstruction of extensive facial defects. Although the feasibility of the procedure is well established, new challenges face the field in its second decade.Methods:The authors’ team has successfully treated patients with extensiv

BACKGROUND Face transplant teams have an ethical responsibility to restore the donor's likeness after allograft procurement. This has been achieved with masks constructed from facial impressions and three-dimensional printing. The authors compare the accuracy of conventional impression and three-dimensional printing technology. METHODS For three subjects, a three-dimensionally-printed mask was created using advanced three-dimensional imaging and PolyJet technology. Three silicone masks were made using an impression technique; a mold requiring direct contact with each subject's face was reinforced by plaster bands and filled with silicone. Digital models of the face and both masks of each subject were acquired with Vectra H1 Imaging or Artec scanners. Each digital mask model was overlaid onto its corresponding digital face model using a seven-landmark coregistration; part comparison was performed. The absolute deviation between each digital mask and digital face model was compared with the Mann-Whitney U test. RESULTS The absolute deviation (in millimeters) of each digitally printed mask model relative to the digital face model was significantly smaller than that of the digital silicone mask model (subject 1, 0.61 versus 1.29, p < 0.001; subject 2, 2.59 versus 2.87, p < 0.001; subject 3, 1.77 versus 4.20, p < 0.001). Mean cost and production times were $720 and 40.2 hours for three-dimensionally printed masks, and $735 and 11 hours for silicone masks. CONCLUSIONS Surface analysis shows that three-dimensionally-printed masks offer greater surface accuracy than silicone masks. Greater donor resemblance without additional risk to the allograft may make three-dimensionally-printed masks the superior choice for face transplant teams.

BACKGROUND Autologous bone grafts remain a standard of care for the reconstruction of large bony defects, but limitations persist. The authors explored the bone regenerative capacity of customized, three-dimensionally printed bioactive ceramic scaffolds with dipyridamole, an adenosine A2A receptor indirect agonist known to enhance bone formation. METHODS Critical-size bony defects (10-mm height, 10-mm length, full-thickness) were created at the mandibular rami of rabbits (n = 15). Defects were replaced by a custom-to-defect, three-dimensionally printed bioactive ceramic scaffold composed of β-tricalcium phosphate. Scaffolds were uncoated (control), collagen-coated, or immersed in 100 μM dipyridamole. At 8 weeks, animals were euthanized and the rami retrieved. Bone growth was assessed exclusively within scaffold pores, and evaluated by micro-computed tomography/advanced reconstruction software. Micro-computed tomographic quantification was calculated. Nondecalcified histology was performed. A general linear mixed model was performed to compare group means and 95 percent confidence intervals. RESULTS Qualitative analysis did not show an inflammatory response. The control and collagen groups (12.3 ± 8.3 percent and 6.9 ± 8.3 percent bone occupancy of free space, respectively) had less bone growth, whereas the most bone growth was in the dipyridamole group (26.9 ± 10.7 percent); the difference was statistically significant (dipyridamole versus control, p < 0.03; dipyridamole versus collagen, p < 0.01 ). There was significantly more residual scaffold material for the collagen group relative to the dipyridamole group (p < 0.015), whereas the control group presented intermediate values (nonsignificant relative to both collagen and dipyridamole). Highly cellular and vascularized intramembranous-like bone healing was observed in all groups. CONCLUSION Dipyridamole significantly increased the three-dimensionally printed bioactive ceramic scaffold's ability to regenerate bone in a thin bone defect environment.

Innovative surgery is defined as a novel procedure, a significant modification of a standard technique, or a new application of an established technique. Although innovation is a crucial part of improving patient care in plastic surgery, there are various ethical considerations and dilemmas in performing unvalidated techniques and procedures, especially for non-life-threatening indications. The aim of this study was to gain a better understanding regarding the motivations and ethical considerations of plastic surgeons in their decision to perform innovative operations. An anonymous, institutional review board-approved, online survey was sent to members of the American Society of Plastic Surgeons and other international plastic surgeons worldwide. The survey asked respondents to rank various factors that influence their decisions to perform innovative plastic surgery, both reconstructive and aesthetic, on a five-point Likert scale. Seven hundred thirty-three of 26,028 plastic surgeons (response rate, 2.9 percent) responded to the survey. Although similar factors were considered to be important for both reconstructive and aesthetic operations, only approximately 50 percent of respondents considered institutional review board approval to be an important factor when considering innovation in both reconstructive (50 percent) and aesthetic surgery (51 percent), suggesting that respondents do not consider innovation a form of research that ought be subject to standard research protections. Overall, the authors' survey suggests that more effort must be extended to ethical training in plastic surgery to create a stronger professional atmosphere regarding innovation and, possibly, to the creation of a more formal group charged with oversight of innovation.

Reconstruction of the nasal lining has traditionally been performed using the folded radial forearm free flap, given its reliable blood supply, pliability, and familiarity to surgeons with respect to its harvest. More recently, the free ulnar forearm flap has been proposed as an alternative reconstructive option for the nasal lining, with safe and reliable outcomes, and improved donor-site morbidity compared with its radial counterpart. In this article, the authors provide educational video footage with accompanying text description of the senior author's (E.D.R) approach to design and elevation of the free ulnar forearm flap for the purpose of reconstructing a composite nasal defect.

Background Since the 1990s, the field of vascularized composite allotransplantation has gained momentum, offering unprecedented solutions for patients with defects not amenable to autologous reconstruction. As with solid organ donation, the vascularized composite allotransplant donor pool remains limited. This systematic review identifies past successes and failures in organ donation campaigns to guide future strategies for expanding vascularized composite allotransplant donation. Methods A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Three databases (PubMed/MEDLINE, PsycINFO, and Embase) were searched through July 31, 2019. The study compiled solid organ and vascularized composite allotransplant campaigns that aimed to increase donor registration. Articles depicting the current state of vascularized composite allotransplant donation were also assessed. Results Of an initial 3318 articles identified, 40 were included. Six articles described direct mail or print interventions, 10 depicted Web-based interventions, 13 dealt with interpersonal interventions, and seven used multimodal interventions. Four articles described the current state of vascularized composite allotransplant donation. A qualitative synthesis was conducted. The authors found that social media campaigns can have a robust but fleeting effect on registration trends and that interpersonal interventions are effective at increasing registration rates. In addition, the opportunity for participants to immediately register as organ donors, by means of either return mail, in-person, or online, is vital to campaign success. Conclusions Public organ donation campaigns have had success in increasing organ donor registration rates, particularly through the use of social media and interpersonal interventions that allow for immediate registration. Synthesizing this information, we propose a multimodal campaign to expand the vascularized composite allotransplant donor pool.

Changes made to the forehead and periorbital region can have dramatic effects in gender-affirmation surgery. Removal of frontal bossing and alteration of orbital shape can result in significant facial feminization. This elective surgical intervention must be safe, reliable, and aesthetically effective. The described technique of frontal and periorbital bone contouring allows for a safe and consistent surgical outcome in properly selected patients. Nuances in specific technical maneuvers in this operation can have profound effects on safety and aesthetic outcomes. In this article, specific points are detailed in text and video describing the senior author's (E.D.R) surgical approach.

Chronic frontal sinus infections in the setting of previous trauma or tumor removal are challenging clinical scenarios. To remove and débride all chronically infected tissue, obliterate dead space, and provide a stable reconstructive yet aesthetic contour are critical tasks in managing these patients. The vascularized free fibula is an ideal flap for this situation; in this article, the authors detail their technique in a patient with chronic frontal sinus infections complicated by mucocele formation.

Technical success has been achieved in several forms of vascularized composite allotransplantation, including hand, face, penis, and lower extremity. However, the risks of lifelong immunosuppression have limited these procedures to a select group of patients for whom nontransplant alternatives have resulted in unsatisfactory outcomes. Recent reports of facial allograft failure, and subsequent reconstruction using autologous tissues, have reinforced the idea that a surgical contingency plan must be in place in case this devastating complication occurs. Interestingly, backup plans in the setting of vascularized composite allotransplantation consist of the nontransplant alternatives that were deemed suboptimal in the first place. Moreover, these options may have been exhausted before transplantation, and may therefore be limited in the case of allograft loss or reamputation. In this article, the authors describe the surgical and nonsurgical alternatives to hand, face, penis, and lower extremity transplantation. In addition, the authors explore the ethical implications of approaching vascularized composite allotransplantation as a "last resort" or as a "high-risk, improved-outcome" procedure, focusing on whether nontransplant options eventually preclude vascularized composite allotransplantation, or whether vascularized composite allotransplantation limits future nontransplant reconstruction.

Reconstruction of extensive facial and scalp burns can be increasingly challenging, especially in patients that have undergone multiple procedures with less than ideal outcomes resulting in restricting neck and oral contractures, eyelid dysfunction, and suboptimal aesthetic appearance.To establish a reconstructive solution for this challenging deformity, a multidisciplinary team was assembled to develop the foundation to a facial vascularized composite allotransplantation program. The strategy of developing and executing a clinical transplant was derived on the basis of fostering a cohesive and supportive institutional clinical environment, implementing computer software and advanced technology, establishing a cadaveric transplant model, performing a research facial procurement, and selecting an optimal candidate with the aforementioned burn defect who was well informed and had the desire to undergo face transplantation.Approval from the institutional review board and organ procurement organization enabled our face transplant team to successfully perform a total face, eyelids, ears, scalp, and skeletal subunit transplant in a 41-year-old man with a full face and total scalp burn.The culmination of knowledge attained from previous experiences continues to influence the progression of facial vascularized composite allotransplantation. This surgical endeavor methodically and effectively synchronized the fundamental principles of aesthetic, craniofacial, and microvascular surgery to restore appearance and function to a patient suffering from failed conventional surgery for full face and total scalp burns. This procedure represents the most extensive soft-tissue clinical face transplant performed to date.Therapeutic, V.

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.

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.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.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).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.Therapeutic, IV.

Multiple perfusion assessment technologies exist to identify compromised microvascular free flaps. The effectiveness, operability, and cost of each technology vary. The authors investigated surgeon preference and clinical behavior with several perfusion assessment technologies.A questionnaire was sent to members of the American Society for Reconstructive Microsurgery concerning perceptions and frequency of use of several technologies in varied clinical situations. Demographic information was also collected. Adjusted odds ratios were calculated using multinomial logistic regression accounting for clustering of similar practices within institutions/regions.The questionnaire was completed by 157 of 389 participants (40.4 percent response rate). Handheld Doppler was the most commonly preferred free flap-monitoring technology (56.1 percent), followed by implantable Doppler (22.9 percent) and cutaneous tissue oximetry (16.6 percent). Surgeons were significantly more likely to opt for immediate take-back to the operating room when presented with a concerning tissue oximetry readout compared with a concerning handheld Doppler signal (OR, 2.82; p0.01), whereas other technologies did not significantly alter postoperative management more than simple handheld Doppler. Clinical decision making did not significantly differ by demographics, training, or practice setup.Although most surgeons still prefer to use standard handheld Doppler for free flap assessment, respondents were significantly more likely to opt for immediate return to the operating room for a concerning tissue oximetry reading than an abnormal Doppler signal. This suggests that tissue oximetry may have the greatest impact on clinical decision making in the postoperative period.

BACKGROUND Microvascular reconstruction is the mainstay of treatment in complex scalp defects. The rate of elderly patients requiring scalp reconstruction is increasing, but outcomes in elderly patients are unclear. The purpose of this study was to systematically review the literature pertaining to free tissue transfer for scalp reconstruction in patients older than 65 years to compare outcomes among different free flaps and determine the safety profile of treatment. METHODS A systematic review of the available literature of patients undergoing microvascular scalp reconstruction was completed. Details for patients 65 years and older were extracted and reviewed for data analysis. RESULTS A total of 45 articles (112 patients) were included for analysis. Mean age of the patients was 73.3 ± 6.3 years (men, 69.4 percent; women, 23.4 percent; not reported, 7.2 percent). Mean flap size was 598 cm2 (range, 81 to 2500 cm2). The mean age of patients developing a complication was 72.8 ± 6.4 years and patients that did not develop a complication was 73.4 ± 5.5 years (p = 0.684). Overall, periprocedural mortality was 0.9 percent. Flap failures occurred in two cases (1.8 percent). The overall complication rate was 22.3 percent (n = 25). Complications by flap type varied without reaching statistical significance. CONCLUSIONS Microvascular reconstruction in complex scalp defects is associated with successful outcomes, and chronologic age does not increase mortality or catastrophic flap complications. The most common flaps used to repair scalp defects are anterolateral thigh and latissimus dorsi, but a superior flap type could not be identified.

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 There has been rising interest in computer-aided design/computer-aided manufacturing for preoperative planning and execution of osseous free flap reconstruction. The purpose of this study was to compare outcomes between computer-assisted and conventional fibula free flap techniques for craniofacial reconstruction. Methods A two-center, retrospective review was carried out on patients who underwent fibula free flap surgery for craniofacial reconstruction from 2003 to 2012. Patients were categorized by the type of reconstructive technique: conventional (between 2003 and 2009) or computer-aided design/computer-aided manufacturing (from 2010 to 2012). Demographics, surgical factors, and perioperative and long-term outcomes were compared. Results A total of 68 patients underwent microsurgical craniofacial reconstruction: 58 conventional and 10 computer-aided design and manufacturing fibula free flaps. By demographics, patients undergoing the computer-aided design/computer-aided manufacturing method were significantly older and had a higher rate of radiotherapy exposure compared with conventional patients. Intraoperatively, the median number of osteotomies was significantly higher (2.0 versus 1.0, p=0.002) and the median ischemia time was significantly shorter (120 minutes versus 170 minutes, p=0.004) for the computer-aided design/computer-aided manufacturing technique compared with conventional techniques; operative times were shorter for patients undergoing the computer-aided design/computer-aided manufacturing technique, although this did not reach statistical significance. Perioperative and long-term outcomes were equivalent for the two groups, notably, hospital length of stay, recipient-site infection, partial and total flap loss, and rate of soft-tissue and bony tissue revisions. Conclusion Microsurgical craniofacial reconstruction using a computer-assisted fibula flap technique yielded significantly shorter ischemia times amidst a higher number of osteotomies compared with conventional techniques.

Ten years after the first face transplantation, the available data in peer-reviewed literature, various media outlets, and recent specialty meetings and courses are conflicting and inconsistently reported. The purpose of this study was to consolidate the available data by means of multiple sources to reflect an accurate and current state of facial vascularized composite allotransplantation as of December of 2015.Using applied search terms pertaining to face transplantation, a systematic PubMed search, Google search, and review of Plastic Surgery Education Network News Connection e-mailed newsletters were performed, and data presented at three meetings (i.e., the most recent American Society of Reconstructive Transplantation biennial meeting, the American Society of Reconstructive Microsurgery annual meeting, and the biennial AO North America State of the Art: Face Reconstruction and Transplantation course) were consolidated to capture the most contemporary and accurate data in face transplantation.A total of 37 face transplants have been performed (20 partial and 17 full face) from 2005 to December of 2015. A discrepancy between actual transplantations performed and peer-reviewed reports exists at multiple time points, with a propensity for underreporting. Ten cases were described through media outlets but were not reported by the surgical teams in peer-reviewed literature. Two clinical cases were not described in peer-reviewed literature or media. There have been a total of five deaths, and posttransplant malignancy and revision surgery have been underreported.This serves as the most contemporary and all-inclusive face transplantation review. There is a critical need for timely reporting and outcome transparency in the reconstructive transplant community.Therapeutic, V.

The application of aesthetic, craniofacial, and microsurgical principles in the execution of face transplantation may improve outcomes. Optimal soft-tissue face transplantation can be achieved by incorporating subunit facial skeletal replacement and subsequent tissue resuspension. The purpose of this study was to establish a reconstructive solution for a full face and scalp burn and to evaluate outcome precision and consistency.Seven mock face transplants (14 cadavers) were completed in the span of 1 year. Components of the vascularized composite allograft included the eyelids, nose, lips, facial muscles, oral mucosa, total scalp, and ears; and skeletal subunits of the zygoma, nasal bone, and genial segment. Virtual surgical planning was used for osteotomy selection, and to evaluate postoperative precision of hard- and soft-tissue elements.Each transplant experience decreased each subsequent transplant surgical time. Prefabricated cutting guides facilitated a faster dissection of both donor and recipient tissue, requiring minimal alteration to the allograft for proper fixation of bony segments during inset. Regardless of donor-to-recipient size discrepancy, ample soft tissue was available to achieve tension-free allograft inset. Differences between virtual transplant simulation and posttransplant measurements were minimal or insignificant, supporting replicable and precise outcomes.This facial transplant model was designed to optimize reconstruction of extensive soft-tissue defects of the craniofacial region representative of electrical, thermal, and chemical burns, by incorporating skeletal subunits within the allograft. The implementation of aesthetic, craniofacial, and microsurgical principles and computer-assisted technology improves surgical precision, decreases operative time, and may optimize function.

Background Cadaveric face transplant models are routinely used for technical allograft design, perfusion assessment, and transplant simulation but are associated with substantial limitations. The purpose of this study was to describe the experience of implementing a translational donor research facial procurement and solid organ allograft recovery model. Methods Institutional review board approval was obtained, and a 49-year-old, brain-dead donor was identified for facial vascularized composite allograft research procurement. The family generously consented to donation of solid organs and the total face, eyelids, ears, scalp, and skeletal subunit allograft. Results The successful sequence of computed tomographic scanning, fabrication and postprocessing of patient-specific cutting guides, tracheostomy placement, preoperative fluorescent angiography, silicone mask facial impression, donor facial allograft recovery, postprocurement fluorescent angiography, and successful recovery of kidneys and liver occurred without any donor instability. Preservation of the bilateral external carotid arteries, facial arteries, occipital arteries, and bilateral thyrolinguofacial and internal jugular veins provided reliable and robust perfusion to the entirety of the allograft. Total time of facial procurement was 10 hours 57 minutes. Conclusions Essential to clinical face transplant outcomes is the preparedness of the institution, multidisciplinary face transplant team, organ procurement organization, and solid organ transplant colleagues. A translational facial research procurement and solid organ recovery model serves as an educational experience to modify processes and address procedural, anatomical, and logistical concerns for institutions developing a clinical face transplantation program. This methodical approach best simulates the stressors and challenges that can be expected during clinical face transplantation. Clinical question/level of evidence Therapeutic, V.

Injuries to the face can potentially lead to destruction of vital structures, with devastating sequelae to the patient. Facial fractures, especially of the midface, are often complicated by ocular injuries. The purpose of this study was to systematically review the literature to better understand specific fracture patterns associated with ocular injuries, including visual impairment and blindness.The PubMed, EMBASE, and Cochrane databases from January of 2004 to April of 2010 were systematically reviewed to identify relevant studies. Only those that investigated facial fractures with concomitant ocular injuries, visual impairment, and/or blindness were included. Studies that described nonfacial fractures or those that only focused on the function of extraocular muscles were excluded. Case reports, nonsystematic reviews, and studies with fewer than 10 patients were also excluded.Eleven articles met study criteria and were included for analysis. There were a total of 14,535 patients, with an average of 1211 patients (range, 39 to 4426) per study. Level of evidence included levels II (n = 1 study), III (n = 1), and IV (n = 9). The mean reported rate of acute visual loss was 1.7 percent. Periorbital and orbital blowout fractures were more often complicated by ocular injuries compared with other facial fracture patterns. High-impact zygomatic fractures were most commonly associated with blindness.Existing studies exploring ocular injuries, visual impairment, and blindness associated with facial fractures offer conflicting data. Specifically directed studies are required so that significant correlations between specific fracture patterns and specific ocular injuries can be drawn.Risk, IV.

Vascularized composite tissue allotransplantation has demonstrated clinical success with standard immunosuppression in hand and upper extremity transplantation. The authors developed a fibular vascularized composite tissue allotransplantation model in nonhuman primates to investigate healing and rejection patterns of bone and associated tissues.Five fibular vascularized composite tissue allotransplantations were performed between mismatched cynomolgus macaques (Macaca fascicularis). Vascularized fibular segments with associated muscle and skin were transplanted to recipient forearm radius defects. Recipients were treated with either tacrolimus monotherapy or tacrolimus plus co-stimulatory blockade with a novel anti-CD28 antibody. Animals were followed for 6 months with serial radiographs, blood sample collection, and biopsies. At the study endpoint, angiographic, biomechanical, histologic, and immunologic assays were performed.All animals survived to the experimental endpoint of 180 days. Rapid or immediate skin loss was evident secondary to vascular compromise (n = 3) or rejection (n = 1) in four animals. Despite loss of nonbony segments and the development of transplant arteriopathy consistent with chronic rejection in two animals, serial radiologic imaging and histology demonstrated bone healing and donor-recipient bony union by 10 weeks in all animals. Histology confirmed the presence of viable cortical and marrow elements. Biomechanical analysis supported donor-recipient bony union. Short-tandem repeated genotypic analysis revealed that donor marrow had been completely replaced by recipient marrow.In contrast to successes in extremity vascularized composite tissue allotransplantation, the authors' nonhuman primate fibular vascularized composite tissue allotransplantation model showed early skin loss, replacement of donor bone marrow, and chronic rejection. Donor-recipient bone union did occur and supports the potential for reconstruction of bony continuity defects using isolated vascularized bone allotransplants.

Background To date, only limited case reports involving isolated bilateral zygomatic arch fractures exist. This fracture pattern is defined by the presence of bilateral zygomatic arch fractures and the absence of any other facial fractures. The purpose of this study was to systematically review a large trauma database to determine whether this fracture pattern exists and, if so, to elucidate the mechanism of injury and associated concomitant injuries. Methods A retrospective review of all patients admitted to the R Adams Cowley Shock Trauma center from February of 1998 to December of 2009 was conducted. International Classification of Diseases, Ninth Revision coding of computed tomographic scans was used to identify patients with zygoma fractures. The facial computed tomographic scans of all patients coded with bilateral zygoma fractures were reviewed to determine whether any had isolated bilateral zygomatic arch fractures. Medical charts were reviewed extensively. Results Five patients (0.24 percent of all zygoma fractures, 3.18 percent of bilateral zygoma fractures) were found to have isolated bilateral zygomatic arch fractures. All five patients had evidence of skull impact with at least one skull fracture and one skull base fracture. Glasgow Coma Scale scores (range, 6 to 14; average, 8.2) were significantly lower (t test, two-sided, p=0.01) compared with all patients (average, 12.2) with facial trauma during the study period. Conclusions Isolated bilateral zygomatic arch fractures do exist. The authors' findings suggest skull impacts as the inciting mechanism of injury and an intimate link with skull base force transmission. The severe nature of this injury warrants a search for concomitant injuries to the head, brain, and spinal cord.

The aim of lower extremity reconstruction has focused on early wound coverage and functional recovery but rarely aesthetics. Free muscle flaps provide durable coverage; however, they require skin graft coverage and result in muscle atrophy limiting future revisions. Perforator-based flap reconstructions can be easily elevated to allow for both orthopedic and contouring procedures. The authors reviewed the role of secondary procedures in achieving improved functional and aesthetic results following perforator flap reconstruction of lower extremity defects.A retrospective review identified 70 patients treated at R Adams Cowley Shock Trauma Center with 73 free perforator flaps for coverage of lower extremity wounds from 2002 to 2009.Seventy patients were identified who underwent reconstruction with a perforator flap: 65 with anterolateral thigh flaps and five with superficial circumflex iliac artery flaps. Nineteen of these patients underwent 32 refinement procedures of the reconstructed limb. Fifteen refinements were performed with suction-assisted lipectomy, 21 with complex tissue rearrangement, including sharp debulking, and one with tissue expanders. Twenty-seven of the 70 patients underwent 40 orthopedic-related secondary procedures in which the free flap was elevated. The most common reasons for the orthopedic interventions were tibial nonunion requiring bone grafting (n = 17) and osteomyelitis (n = 11).Limb salvage remains the primary goal of lower extremity reconstruction. Following convalescence and functional recovery, however, appearance becomes increasingly important with regard to quality of life. Initial flap selection with free perforator flaps, meticulous inset, and secondary refinements provide superior functional and aesthetic outcomes.

Since 2005, seven facial composite tissue allotransplantations have been performed in five different centers in three countries. Four teams have reported their outcomes in separate publications. The authors sought to review the first four global experiences and compare several factors. This review facilitates discussion of indications and future implications for facial composite tissue allotransplantation.A thorough review of five publications by the four transplantation groups was conducted. Additional information gathered from official press releases or surgeon presentations was also included. Summary of data and comparative analysis were performed.Patient selection is of utmost importance; specifically, patient compliance with the immunosuppressive and postoperative regimen. Functional and aesthetic improvement must be achieved by composite tissue allotransplantation reconstruction to justify lifelong immunosuppression; therefore, patients with loss of perioral and/or periorbital structures have priority. Objective measures are required to monitor this functional restoration. The importance of viral mismatch was demonstrated by the severe cytomegalovirus viremia observed in the third facial transplant patient. Finally, the mucosa appears to be a predictor of rejection and is more antigenic than skin. Histopathologic diagnosis of mucosal rejection may allow early treatment and prevention of subsequent diffuse composite tissue allotransplant rejection.The pioneering teams that ventured into facial composite tissue allotransplantation offered their patients improved aesthetic, functional, and social outcomes not possible with conventional measures in a single procedure. In addition, these innovative facial composite tissue allografts have provided early data on important factors related to patient selection, donor/recipient matching, immunosuppressive protocols, objective measures of functional recovery, and monitoring of acute graft rejection.

Background: Frontobasal injury is a classic craniomaxillofacial fracture affecting the anterior cranial base. No data exist regarding the degree of frontobasal injury and associated midfacial fractures. The authors propose a classification of frontobasal and midface fractures involving the cranial base based on cadaveric experiments and comprehensive clinical experience. Methods: An institutional review board–approved retrospective review was conducted on patients with frontobasal fractures from 1995 to 2005. Fractures were categorized by pattern, location, midfacial involvement (impure), and complications compiled. One hundred five cadaveric heads underwent blunt impact to the frontal bone and upper midface. Calvarial vault, cranial base, and midface fracture patterns were categorized. Results: Three frontobasal fracture patterns were identified. Isolated linear cranial base fractures constitute type I. Vertical-linear fractures of the skull vault (frontal bone) occur in combination with base fractures, representing type II (vault and base). Comminution of the frontolateral skull vault and orbital roof in association with a linear base fracture constitute type III. Two hundred ninety patients were identified with 49 complications (cerebrospinal fistula, 24; and infectious 25). Type III (n = 159) had the highest complication rate (impure, 29 percent; pure, 17 percent), followed by type II (impure, 19 percent; pure, 5 percent). There is essentially no extension of midface fractures to the cranial vault. Conclusions: Frontobasal fractures have three unique and reproducible patterns based on vector, location, and force. This new classification scheme, paired with known patterns of midfacial injuries, assists in fully understanding frontofaciobasal injury and its complications. Overwhelmingly, impure type II and any type III fractures are associated with a high rate of complications and must be carefully managed.

The technical success of facial composite tissue allotransplantation demands full understanding of superficial and deep perfusion for reliable microvascular transfer. Candidates with composite midface defects require an appreciation of the circulatory patterns to design a composite midface allotransplant.External carotid vascular territories were evaluated in 10 cadavers to determine the reliability of facial soft-tissue flaps based on a single vascular pedicle. The right common carotid artery was injected with red latex and the left was injected with blue latex. Dual perfusion was confirmed by purple, following two-color mixing. Vascular pedicles included the superficial temporal, transverse facial, and facial arteries. In five additional cadavers, the midface segment was isolated by Le Fort III osteotomy after two-color latex injection with inclusion of the internal maxillary vascular pedicle. Cadavers were imaged with three-dimensional computed tomographic reconstructions following latex injection to confirm perfusion patterns.In soft-tissue facial flaps, unilateral carotid dominance was seen in the nasal dorsum and tip, confirming reliable supply by a single external carotid artery. In midface flaps, bilateral perfusion was seen in the maxilla. Ipsilateral perfusion was observed at the zygomaticomaxillary complex without any contralateral contribution.Dual soft-tissue perfusion was confirmed in most specimens at the nasal, central face, and maxilla. The inclusion of the maxilla in the design of a facial composite allotransplant demands bilateral vascular pedicles based on the internal maxillary arteries. The authors highlight a procurement strategy for design of such flaps.

BACKGROUND:: Patients presenting with traumatic craniomaxillofacial fractures often have occult concomitant injuries. This study was designed to determine whether facial fracture patterns are associated with a particular constellation of concomitant head and neck injuries. METHODS:: A retrospective review of 4786 consecutive patients diagnosed with maxillofacial fractures at a dedicated urban trauma center from 1998 to 2005 was conducted; maxillofacial fractures and cervical spine injuries were grouped by dividing the craniomaxillofacial skeleton and cervical spine into thirds. Univariate and multivariate logistic regression analyses were used to identify associations between facial fractures and other traumatic injuries. RESULTS:: Among all patients with facial fractures, 461 (9.7 percent) also had cervical spine injuries and 2175 (45.5 percent) had associated head injuries. Fractures of the upper face were associated with increased likelihood of mid lower cervical spine injuries, severe intracranial injuries, and increased mortality rates. Unilateral mandible injuries were associated with an increased likelihood of having upper cervical spine injuries, whereas unilateral midface injuries were associated with basilar skull fractures and several intracranial injuries. Finally, bilateral midface injuries were associated with basilar skull fracture and death. CONCLUSIONS:: Craniomaxillofacial fractures are commonly associated with head and cervical spine injuries that involve predictable patterns of force dispersion from the maxillofacial skeleton and transmission to the cranial vault and cervical spine. These results suggest that concomitant injuries should be investigated closely with distinct types of facial fractures. Language: en

Background Osteoradionecrosis is a serious complication of head and neck radiotherapy. Advanced cases are not amenable to periodic debridement, systemic antibiotics, or hyperbaric oxygen therapy. The authors sought to describe a cost-effective approach for patients with advanced craniofacial osteoradionecrosis. Methods Fifteen consecutive patients with craniofacial osteoradionecrosis were treated with radical resection and immediate microvascular free flap reconstruction at Johns Hopkins Hospital or R Adams Cowley Shock Trauma Center from 2002 to 2008. Demographic data were reviewed, and procedure costs were used to compare treatment options. Results All patients presented with intractable osteoradionecrosis, and most failed conservative therapy. Most cases (60 percent) involved the mandible, and the fibula was the flap of choice (73 percent). The median follow-up was 14 months, with 13 percent complications. Relative cost analysis for hyperbaric oxygen, surgical debridement, and a hospital stay was $25,010; simultaneous resection-microvascular free flap reconstruction and 7-day hospital stay were $30,030. The majority of patients, however, had prior attempts at conservative therapy followed by simultaneous resection and reconstruction; therefore, the average total relative cost per patient was $55,040 ($25,010 + $30,030). Conclusion Definitive treatment of advanced or intractable osteoradionecrosis with simultaneous resection and microvascular composite flap reconstruction is not only definitive but financially sound.

Background: Posttraumatic, high-energy defects of the midface can be challenging to reconstruct because they involve extensive composite tissue loss and result in significant permanent functional and cosmetic deformity. These injuries require replacement of the bony framework, external soft tissue, and intraoral mucosa. Local skin flaps and nonvascularized bone grafts have been used for reconstruction, but bony resorption and the associated soft-tissue collapse limit long-term viability. The authors present a classification of maxillary defects following high-energy trauma and a treatment algorithm using vascularized bone flaps. Methods: Fourteen patients with significant maxillary loss from high-energy trauma underwent reconstruction with composite vascularized bone flaps. Eight patients had fibula flaps and six had iliac crest flaps. There were five women and nine men, with a mean age of 36.3 years (range, 21 to 48 years) and a mean follow-up of 18 months (range, 5 to 54 months). Results: Thirteen of the 14 flaps survived. Nine patients had additional procedures. Nine patients had oronasal fistulas and eight were dependent on gastrostomy tubes preoperatively. All patients were able to feed orally without nasal regurgitation postoperatively. All patients achieved stable restoration of the midfacial architecture. Conclusions: The classification scheme presented centers on the missing maxillary subunits. The reconstructive algorithm is based on the type of defect, tissue requirement, and donor tissues necessary to restore facial projection and prosthodontic rehabilitation. Iliac crest and fibula bone free flaps are ideal for restoring a variety of traumatic maxillary defects. The authors advocate early reconstructive intervention using vascularized bone flaps to achieve superior functional and cosmetic outcomes.

Mandibular condyle fractures are common following facial trauma and carry an increased risk for concomitant blunt carotid artery injuries. Further elucidation of this relationship may improve vascular injury screening and management.A retrospective cohort study was performed for all patients sustaining condylar fractures presenting to a large trauma center over twelve years. Fracture locations were classified according to the Strasbourg Osteosynthesis Research Group (1, condylar head; 2, condylar neck; and 3, extracapsular condylar base). Carotid artery injury severity was based on the Biffl scale. Severe vascular injury was defined as a Biffl score greater than I.605 patients were identified with mandibular condyle fractures consisting of 21.0 percent (n = 127) condylar head; 26.8 percent (n = 162) condylar neck; and 52.2 percent (n = 316) extracapsular condylar base. The incidence of vascular injuries in this population was 5.5 percent (n = 33), of which 75.8 percent (n = 25) were severe. Severe vascular injuries occurred in 1.6 percent (n = 2) of condylar head, 2.5 percent (n = 4) of condylar neck, and 6.0 percent (n = 19) of extracapsular condylar base fractures (p0.05). Extracapsular condylar base fractures were independently associated with a 2.94-fold increased risk of a severe blunt carotid artery injury compared with other condyle fractures on multivariable analysis (p0.05).Extracapsular subcondylar fractures should heighten suspicion for concomitant blunt carotid artery injury. The data support a force transmission mechanism of injury in addition to direct injury from bony fragments.Risk, II.
