Facial Transplantation for an Irreparable Central and Lower Face Injury: A Modernized Approach to a Classic Challenge

Computerized Surgical Planning in Face Transplantation

Face transplantation (FT) has emerged as a critical intervention for patients with complex facial deformities unsuitable for conventional reconstructive methods. It aims to restore essential functions such as facial expression, mastication, and speech, while also improving psychosocial health. The procedure utilizes various surgical principles, addressing unique challenges of craniofacial complexity and diverse injury patterns. The integration of Computerized Surgical Planning (CSP) leverages computer-aided technologies to enhance preoperative strategy, intraoperative navigation, and postoperative assessment. CSP utilizes three-dimensional computed tomography, printing, angiography, and navigation systems, enabling surgeons to anticipate challenges and reduce intraoperative trial and error. Through four clinical cases, including a groundbreaking combined face and bilateral hand transplant, CSP's role in FT is highlighted by its ability to streamline operative processes and minimize surgical revisions. The adoption of CSP has led to fewer cadaveric rehearsals, heightened operative precision, and greater alignment with preoperative plans. Despite CSP's advancements, it remains complementary to, rather than a replacement for, clinical expertise. The demand for technological resources and multidisciplinary teamwork is high, but the improved surgical outcomes and patient quality of life affirm CSP's value in FT. The technology has become a staple in reconstructive surgery, signaling a step forward in the evolution of complex surgical interventions.

A World Update of Progress in Lower Extremity Transplantation: What's Hot and What's Not

ABSTRACT

The field of vascularized composite allotransplantation (VCA) is the new frontier of solid organ transplantation (SOT). VCA spans life-enhancing/life-changing procedures such as upper extremity, craniofacial (including eye), laryngeal, tracheal, abdominal wall, penis, and lower extremity transplants. VCAs such as uterus transplants are life giving unlike any other SOT. Of all VCAs that have shown successful intermediate- to long-term graft survival with functional and immunologic outcomes, lower extremity VCAs have remained largely underexplored. Lower extremity transplantation (LET) can offer patients with improved function compared to the use of conventional prostheses, reducing concerns of phantom limb pain and stump complications, and offer an option for eligible amputees that either fail prosthetic rehabilitation or do not adapt to prosthetics. Nevertheless, these benefits must be carefully weighed against the risks of VCA, which are not trivial, including the adverse effects of lifelong immunosuppression, extremely challenging perioperative care, and delayed nerve regeneration. There have been 5 lower extremity transplants to date, ranging from unilateral or bilateral to quadrimembral, progressively increasing in risk that resulted in fatalities in 3 of the 5 cases, emphasizing the inherent risks. The advantages of LET over prosthetics must be carefully weighed, demanding rigorous candidate selection for optimal outcomes.

Acute Rejection Rates in Vascularized Composite Allografts: A Systematic Review of Case Reports

INTRODUCTION

Vascularized Composite Allografts (VCA) are usually performed in a full major histocompatibility complex mismatch setting, with a risk of acute rejection depending on factors such as the type of immunosuppression therapy and the quality of graft preservation. In this systematic review, we present the different immunosuppression protocols used in VCA and point out relationships between acute rejection rates and possible factors that might influence it.

METHODS

This systematic review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We systematically searched Medline (PubMed), Embase, and The Cochrane Library between November 2022 and February 2023, using following Mesh Terms: Transplant, Transplantation, Hand, Face, Uterus, Penis, Abdominal Wall, Larynx, and Composite Tissue Allografts. All VCA case reports and reviews describing multiple case reports were included.

RESULTS

We discovered 211 VCA cases reported. The preferred treatment was a combination of antithymocyte globulins, mycophenolate mofetil (MMF), tacrolimus, and steroids; and a combination of MMF, tacrolimus, and steroids for induction and maintenance treatment, respectively. Burn patients showed a higher acute rejection rate (P = 0.073) and were administered higher MMF doses (P = 0.020).

CONCLUSIONS

In contrast to previous statements, the field of VCA is not rapidly evolving, as it has encountered challenges in addressing immune-related concerns. This is highlighted by the absence of a standardized immunosuppression regimen. Consequently, more substantial data are required to draw more conclusive results regarding the immunogenicity of VCAs and the potential superiority of one immunosuppressive treatment over another. Future efforts should be made to report the VCA surgeries comprehensively, and muti-institutional long-term prospective follow-up studies should be performed to compare the number of acute rejections with influencing factors.

Immunosuppressive strategies in face and hand transplantation: a comprehensive systematic review of current therapy regimens and outcomes

Background

Recipients of Vascularized Composite Allotransplants require effective immunosuppressive therapy to prevent graft rejection. This systematic review summarizes the current body of literature on immunosuppressive regimens used in face and hand transplants while summarizing their outcome in terms of rejection, renal failure, and infections.

Methods

A systematic search of electronic databases was conducted to identify relevant studies from 1998 until July 1st, 2023. We included all studies that discussed immunosuppressive strategies in face and hand transplant recipients according to PRISMA.

Results

The standard triple maintenance therapy was mostly adjusted due to nephrotoxicity or high incidence of rejection. The most common alternative treatments utilized were sirolimus (25/91; 27.5%) or everolimus (9/91; 9.9%) following hand- and photophoresis (7/45; 15.6%), sirolimus (5/45; 11.1%) or belatacept (1/45; 2.2%) following face transplantation. Episodes of rejection were reported in 60 (65.9%) of hand- and 33 (73%) of face transplant patients respectively. Graft loss of 12 (13.2%) hand and 4 (8.9%) face transplants was reported. Clinical CMV infection was observed in 6 (6.6%) hand and 7 (15.5%) face transplant recipients.

Conclusions

Based on the herein presented data, facial grafts exhibited a heightened incidence of rejection episodes and CMV infections. Facial mucosa adds complexity to the immunological graft composition highlighting the need of individualized immunosuppressive regimens and further research.

Vascularized Composite Allograft Versus Prosthetic for Reconstruction After Facial and Hand Trauma: Comparing Cost, Complications, and Long-term Outcome

ABSTRACT

In the past decade, vascularized composite allotransplantation (VCA) has become clinical reality for reconstruction after face and hand trauma. It offers patients the unique opportunity to regain form and function in a way that had only been achieved with traditional reconstruction or with the use of prostheses. On the other hand, prostheses for facial and hand reconstruction have continued to evolve over the years and, in many cases, represent the primary option for patients after hand and face trauma. We compared the cost, associated complications, and long-term outcomes of VCA with prostheses for reconstruction of the face and hand/upper extremity. Ultimately, VCA and prostheses represent 2 different reconstructive options with distinct benefit profiles and associated limitations and should ideally not be perceived as competing choices. Our work adds a valuable component to the general framework guiding the decision to offer VCA or prostheses for reconstruction after face and upper extremity trauma.

Re-cognizing the new self: The neurocognitive plasticity of self-processing following facial transplantation

The face is a defining feature of our individuality, crucial for our social interactions. But what happens when the face connected to the self is radically altered or replaced? We address the plasticity of self-face recognition in the context of facial transplantation. While the acquisition of a new face following facial transplantation is a medical fact, the experience of a new identity is an unexplored psychological outcome. We traced the changes in self-face recognition before and after facial transplantation to understand if and how the transplanted face gradually comes to be perceived and recognized as the recipient's own new face. Neurobehavioral evidence documents a strong representation of the pre-injury appearance pre-operatively, while following the transplantation, the recipient incorporates the new face into his self-identity. The acquisition of this new facial identity is supported by neural activity in medial frontal regions that are considered to integrate psychological and perceptual aspects of the self.

Validating a Novel Device to Improve Skin Color Matching for Face Transplants

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.

Youngest Composite Full-Face Transplant: A Model for Vascularized Composite Allograft in Younger Populations

BACKGROUND

The field of face transplantation continues to evolve, with more complex defects being addressed, and, at the same time, increased outcome expectations. Given our unique long-term experience in this field, we consented one of the youngest patients to undergo a full-face transplant.

METHODS

An 18-year-old woman presented with complete destruction of her central face and craniofacial structures. She had coexisting major injuries, including pituitary gland, visual axis, and motor control. After extensive rehabilitation and reconstruction techniques, the patient underwent face transplant on May 4, 2017, at the age of 21 years.

RESULTS

The total operative time for the recipient was 26 hours. There were no major perioperative complications. Since transplant, the patient has undergone 3 revision surgeries. She is near completely independent from a daily life activity standpoint. She has had 1 episode of rejection above grade II that was successfully treated with a short-term increased in immunosuppression.

CONCLUSIONS

Contrary to data in solid organ transplantation where youth is associated with increased risk of rejection, our current algorithm in immunosuppression, combined with this patient's compliance, has led to only 1 rejection episode beyond grade II. This successful transplant can serve as a model for future vascularized composite transplants in younger populations.

Current Concepts in Maxillary Reconstruction

SUMMARY

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.

Recipient Selection Criteria for Facial Transplantation: A Systematic Review

BACKGROUND

Recipient selection is an important determinant of surgical outcomes in facial transplantation (FT). Appropriately, each FT program develops their own guidelines for recipient selection criteria. Currently, there is no resource to simultaneously assess and identify similarities and differences between these guidelines. Such information could be useful in distinguishing areas of FT that are well understood from those that could benefit from further exploration.

METHODS

We performed a systematic review of the scientific literature from inception to June 18, 2021, using Pubmed, Embase, Cochrane Library, and Scopus to identify articles pertaining to recipient selection criteria. Clinical trials were identified through the Clinicaltrials.gov registry. United States and international program websites were reviewed for patient-facing information.

RESULTS

Our systematic review yielded 90 suitable articles, 8 clinical trials, and 7 program websites containing the recipient selection criteria of 24 different FT programs. The most reported on recipient criteria were age, positive human immunodeficiency viral status (HIV+), positive hepatitis C viral status, psychosocial stability, and medical compliance. Other criteria were rarely addressed, such as blindness and recipient immune status.

CONCLUSIONS

Guidelines among different face transplant programs are changing over time. We found consensus on certain recipient selection criteria, but the majority remain program or surgeon dependent, emphasizing that FT is still an evolving procedure. Although most programs reported on their recipient selection criteria, the rationale was often missing. Further discussion about recipient selection criteria and the reasoning behind employing or changing them will help advance the field.

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

INTRODUCTION

Self-inflicted gunshot wounds to the face frequently result in devastating injuries; however, there is a paucity of large experiences describing determinants of mortality and outcomes.

METHODS

Using the National Trauma Databank from 2007 to 2015, patients suffering self-inflicted firearm facial injuries were included.

RESULTS

Over 9 years 7869 patients were included: 87.7% were male, 46.4% suffered traumatic brain injury (TBI) and overall in-hospital mortality was 44.7%. The majority (67.8%) of in-hospital mortality occurred within the first 24 hours. Using multiple regression, advanced age (>65 years), presence of TBI, admission hypotension, and decreased Glasgow coma score were each independently associated with increased odds of mortality (all P < 0.001). Mandible or combined mandible/midface fracture injury patterns were most likely to survive (P < 0.001). Of those surviving to hospital discharge, the median [interquartile range] length of stay was 13 [6, 23] days, 86.6% required an intensive care unit stay with 67% requiring intubation and 42.5% tracheostomy. Among survivors, the combined mandible and midface fracture pattern resulted in the highest rates of tracheostomy (70.5%), gastrostomy tube placement (50.5%), and facial operations (87.0%) with a median [interquartile range] of 5 [3, 7] operative trips (all P < 0.001).

CONCLUSIONS

Self-inflicted facial firearm injuries are highly morbid injuries with the majority of in-hospital deaths occurring the first hospital day. Differences including concomitant TBI, facial injury pattern, neurologic status, and presence of hypotension on admission were independently associated with survival/death. More extensive facial injuries (combined mandible and midface fracture patterns) were more likely to survive and required more intensive interventions.

Secondary Rhinoplasty for Unilateral Cleft Nasal Deformity

BACKGROUND

Secondary cleft rhinoplasty presents some of the most challenging cases of both cosmetic and functional nasal deformities. Understanding the anatomy and growth abnormality seen with the cleft nasal deformity helps to tailor surgical management. This article seeks to expand on the application of current concepts in secondary rhinoplasty for unilateral cleft lip nasal deformity.

METHODS

The authors review nasal analysis in the cleft rhinoplasty patient and provide the surgical management for each aspect in the secondary cleft rhinoplasty.

RESULTS

The secondary rhinoplasty was divided into seven areas: piriform hypoplasia, septal reconstruction, dorsal reshaping, tip reshaping, tip projection, alar reshaping, and alar repositioning. Surgical management for each is provided.

CONCLUSION

Secondary cleft rhinoplasty requires an understanding of the structural dysmorphology, and the use of cosmetic, functional, and secondary rhinoplasty techniques for its successful management.

Is Digital Animation Superior to Text Resources for Facial Transplantation Education? A Randomized Controlled Trial

BACKGROUND

Facial transplantation is a complex surgical procedure that requires education of medical professionals, patients, and the general public. The objective of this randomized controlled trial was to compare the educational efficacy of facial transplantation digital animation versus text resources for teaching medical students a complex surgical procedure and its applicable anatomical and surgical principles.

METHODS

Medical student volunteers were recruited and prospectively randomized to an animation or a text group. Students completed preintervention and postintervention assessments of confidence and knowledge of head and neck anatomy and facial transplantation. Student Evaluations of Educational Quality survey assessed student satisfaction with both tools following study crossover. Knowledge assessment was developed using National Board of Medical Examiners guidelines and content validated by four experts. The Cohen d statistic was used to measure the effect size of each intervention.

RESULTS

Thirty-six students were assigned randomly to the animation group (n = 19) or the text (n = 17) group. Postintervention analysis demonstrated significantly higher performance scores in the animation group compared to the text group (p = 0.029). The animation group had a larger effect size (Cohen d = 1.96 versus 1.27). Only students in the animation group reported significantly improved confidence in head and neck anatomy after the intervention (p = 0.002). Both groups demonstrated significantly increased postintervention confidence in knowledge of facial transplantation (p < 0.001). Satisfaction scores revealed that students significantly favored the animation resource (p < 0.001).

CONCLUSIONS

Animation can be an effective tool for facial transplantation education and results in improved student knowledge, confidence, and satisfaction compared to text resources. Facial transplantation can also be used as an educational framework for teaching medical students anatomical and surgical principles.

Preservation solutions for attenuation of ischemia-reperfusion injury in vascularized composite allotransplantation

Vascularized composite allotransplantation represents the final level of the reconstructive ladder, offering treatment options for severe tissue loss and functional deficiencies. Vascularized composite allotransplantation is particularly susceptible to ischemia–reperfusion injury and requires preservation techniques when subjected to extended storage times prior to transplantation. While static cold storage functions to reduce ischemic damage and is widely employed in clinical settings, there exists no consensus on the ideal preservation solution for vascularized composite allotransplantation. This review aims to highlight current clinical and experimental advances in preservation solution development and their critical role in attenuating ischemia–reperfusion injury in the context of vascularized composite allotransplantation.

Plastic Surgery amidst the Pandemic: The New York University Experience at the Epicenter of the COVID-19 Crisis

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.

The 2020 Facial Transplantation Update: A 15-Year Compendium

Over the past 15 years, landmark achievements have established facial transplantation (FT) as a feasible reconstructive option for otherwise irreparable craniofacial defects. However, as the field matures and long-term outcomes begin to emerge, FT teams around the world are now facing new challenges. Data for this review were identified by searches of the PubMed/MEDLINE database from inception through August 2020. All English-language articles pertaining to FT were included. Significant advances in candidate selection, technology, operative technique, posttransplant care, and immunosuppressive management have contributed to the tremendous expansion of the field, culminating in the execution in the past 3 years of 2 facial re-transplantations, and most recently the world’s first successful combined face and double hand transplant in August 2020. Despite these achievements, the allograft donor pool remains limited, with long wait times, requiring surgical experimentation with cross-sex FT. Immunosuppressive management has improved, but significant adverse events continue to be reported. Most recently, the COVID-19 pandemic has placed an unprecedented strain on the healthcare system, with various implications for the practice of reconstructive transplantation. In this article, we provide the most comprehensive and up-to-date FT review, highlighting fundamental lessons learned and recent advancements, while looking toward the challenges ahead. Over the past 15 years, extensive multidisciplinary efforts have been instrumental to the establishment of FT as a feasible reconstructive option. As novel challenges are beginning to emerge, continued collaborative and multispecialty research efforts are needed to further this field.

Maxillofacial Bony Considerations in Facial Transplantation

Alloplastic facial transplantation has become a new rung on the proverbial reconstructive ladder for severe facial wounds in the past couple of decades. Since the first transfer including bony components in 2006, numerous facial allotransplantations across many countries have been successfully performed, many incorporating multiple bony elements of the face. There are many unique considerations to facial transplantation of bone, however, beyond the considerations of simple soft tissue transfer. Herein, we review the current literature and considerations specific to bony facial transplantation focusing on the pertinent surgical anatomy, preoperative planning needs, intraoperative harvest and inset considerations, and postoperative protocols.

Infectious complications of vascularized composite allograft transplantation

PURPOSE OF REVIEW

Vascularized composite allograft (VCA) transplants constitute multiple tissues transplanted together as one functional unit. These procedures are increasing in frequency and complexity, yet data about graft survival, quality of life, and infection risk remain limited.

RECENT FINDINGS

Informative guidance for this patient population is often inferred from the solid organ transplantation literature. Yet, it is important to understand that VCA transplantation additionally carries its own significant and distinctive risk factors for infection.

SUMMARY

In this review, we give an overview of previously described infectious complications of VCA transplantation in the literature, discuss risk factors for future infection in these patients, and discuss how to manage such obstacles.

Limitations and limits and of vascularized composite allotransplantations: can we reach the holy grail?

PURPOSE OF REVIEW

In recent times, vascularized composite allotransplantation (VCA) have been gaining more attention and applications. Currently, VCA are at the highest level of the reconstruction pyramid, and thus the effects expected after them are intended to outweigh what the 'classical' reconstructive surgery can offer us, including even the most advanced microsurgical techniques.

RECENT FINDINGS

Over 40 patients have received a partial or full-face transplant. Others have received penis, uterus, larynx, abdominal wall, and lower extremity transplants. Each type of VCA has its own problems and limitations. However, resolving the limits defined by immunosuppression and improved donor selection would revolutionize all of them.

SUMMARY

Defining the limits and limitations of given procedures will not only allow for better preparation of transplant teams but will also help in determining the direction of future research.

First human facial retransplantation: 30-month follow-up

BACKGROUND

Since the first successful facial transplantation in 2005, the benefits of this procedure in terms of aesthetics, functionality, and quality of life have been firmly established. However, despite immunosuppressive treatment, long-term survival of the allograft might be compromised by chronic antibody-mediated rejection (CAMR), leading to irreversible necrosis of the tissue. In the absence of therapeutic options, this complication is inevitably life-threatening.

METHODS

We report facial retransplantation in a man, 8 years after his first facial transplantation because of extensive disfigurement from type 1 neurofibromatosis and 6 weeks after complete loss of his allograft due to severe CAMR. We describe the chronology of immune-related problems that culminated in allograft necrosis and the eventual loss of the facial transplant, the desensitisation protocol used for this highly immunosensitised recipient, the surgical technicalities of the procedure, the specific psychological management of this patient, and the results from follow-up at 30 months.

FINDINGS

Although the patient had a complicated postoperative course with numerous immunological, infectious, cardiorespiratory, and psychological events, he was discharged after a hospital stay of almost 1 year. He has since been able to re-integrate into his community with acceptable restoration of his quality of life.

INTERPRETATION

This clinical report of the first documented human facial retransplantation is proof-of-concept that the loss of a facial transplant after CAMR can be mitigated successfully by retransplantation combined with an aggressive desensitisation process.

Equity in access to facial transplantation

We examine ethical considerations in access to facial transplantation (FT), with implications for promoting health equity. As a form of vascularised composite allotransplantation, FT is still considered innovative with a relatively low volume of procedures performed to date by a small number of active FT programmes worldwide. However, as numbers continue to increase and institutions look to establish new FT programmes, we anticipate that attention will shift from feasibility towards ensuring the benefits of FT are equitably available to those in need. This manuscript assesses barriers to care and their ethical implications across a number of considerations, with the intent of mapping various factors relating to health equity and fair access to FT. Evidence is drawn from an evolving clinical experience as well as published scholarship addressing several dimensions of access to FT. We also explore novel concerns that have yet to be mentioned in the literature.

Anesthetic Considerations in Facial Transplantation: Experience at NYU Langone Health and Systematic Review

Anesthetic considerations are integral to the success of facial transplantation (FT), yet limited evidence exists to guide quality improvement. This study presents an institutional anesthesia protocol, defines reported anesthetic considerations, and provides a comprehensive update to inform future directions of the field.

Should We Consider Preparing Patients for Future Face Transplant when Managing Complex Facial Trauma?

With advancements in microsurgical technique and experience, face transplantation is becoming a clinical reality and acceptable procedure. Preparation of the maxillofacial skeleton and initial soft-tissue coverage for face transplant candidates is essential for optimizing the ultimate outcome by providing immediate coverage of vital structures, functionality, and a stable skeletal framework. We present our experience of preparing such a patient who underwent a successful face transplant, with an excellent outcome. A 24-year-old man sustained a self-inflicted ballistic injury to his face. Composite tissue deficits included significant soft-tissue loss in the central lower and midface, comminuted fractures of midface, and large bone gaps of the maxilla and mandible. He underwent open reduction internal fixation of bilateral LeFort III, zygomaticomaxillary complex, and complex maxillary and mandibular fractures with titanium plates and a free anterolateral thigh perforator flap to the midface with concomitant pedicled left supraclavicular artery fasciocutaneous flap to the lower face. He subsequently underwent a second free anterolateral thigh perforator for the exposed mandibular hardware due to partial necrosis of the supraclavicular artery fasciocutaneous flap. The patient achieved stable bone reconstruction and soft-tissue coverage and was discharged home. He was placed on the waiting list for a face transplant by another center in the country and eventually underwent a successful face transplant. We believe that the preparation of the patient with complex craniomaxillofacial trauma for face transplant should be considered when the extent of injury exceeds conventional reconstructive limits. Our approach provides the best opportunity for an optimal face transplant outcome while minimizing flap donor site morbidity.

Enhancing Face Transplant Outcomes: Fundamental Principles of Facial Allograft Revision

Facial transplantation (FT) has become a feasible reconstructive solution for patients with devastating facial injuries. Secondary revisions to optimize functional and aesthetic outcomes are to be expected, yet the optimal timing and approach remain to be determined. The purpose of this study was to analyze all facial allograft revisions reported to date, including the senior author's experience with 3 FTs.

Methods

A literature review was performed, with 2 reviewers independently conducting title and abstract screening, followed by a full-text review. All articles mentioning FT revision surgeries were evaluated. The medical records of the senior author's 3 FT recipients were additionally reviewed.

Results

Initially, 721 articles were captured and 37 were included in the final analysis. Thirty-two FTs were reported to have involved posttransplant allograft revisions, with FT recipients undergoing a mean of 4.8 ± 4.6 revision procedures. The mean duration between FT and the first revision procedure was 149 ± 179 days. A wide spectrum of revisions was identified and categorized as involving the soft tissues, craniofacial skeleton, dentition, oronasal cavity, salivary glands, facial nerve, or ocular region. In the senior author's experience, when indicated, posttransplant occlusal changes and integrity of the donor-recipient intraoral interface were successfully addressed with secondary procedures without allograft compromise or loss.

Conclusions

The worldwide experience shows that secondary procedures are nearly ubiquitous after FT and can be safely performed at various timepoints. The authors thereby establish 5 distinct categories of facial allograft revisions and define 7 critical principles to optimize posttransplant procedures.

Crane Principle Revisited

BACKGROUND

Scalp and forehead defects represent one of the most complex defects for reconstruction. The nature of these sites being hair bearing, together with the complicated nature of the injuries, for example, electrical burns and motor vehicle accidents, and of course the aesthetic concern being in the face, all add to the complexity of reconstruction.

METHODS

This is a case series representing the experience of the authors in using the "crane principle" in the reconstruction of various defects in the forehead and the scalp presented to emergency department, Cairo University Hospital, for the period between January 2018 and January 2019.

RESULTS

Twenty patients, 15 men and 5 women, presented with various soft tissue defects of the forehead and the scalp. The injuries of eighteen patients were due to motor vehicle accidents, and 2 patients had postelectrical burns. Age range was from 20 to 65 years, with a mean follow-up of 8 months. The number of total complications was 5. Three patients had wound dehiscence, and 2 patients had ulceration in the grafts placed at the flap donor site.

CONCLUSION

Crane principle represents an adequate reconstruction tool for forehead and scalp defects especially when the access to free flap and more complex reconstruction techniques is not available.

Contemporary reconstruction after complex facial trauma

Complex facial trauma requires complex repair and solutions. This process is challenging for the surgeon who seeks to manage the expectations of the patient and family while achieving the best possible result. Historically, the use of pedicled flaps, and then free tissue transfer, were the primary techniques utilized. Advancements in soft-tissue reconstruction, such as perforator flaps and pre-expanded and prefabricated flaps, allow refinement of the soft-tissue reconstruction process to create the best initial soft-tissue coverage. The advent of contemporary technologies, such as virtual surgical planning, stereolithography and customized implants and plates, facilitates a tailored approach to the patient’s reconstructive needs for precise bony reconstruction. When surgical and technological techniques are combined in complementary multistage reconstructions, better reconstructive and aesthetic outcomes are achievable than ever before. In this review, the authors present a summary of the management of complex facial trauma based on the senior author’s broad experience. Initial management and contemporary reconstructive techniques and technology to provide optimal outcomes are reviewed. A case series of complex facial traumas and their reconstructive process is also presented to demonstrate how complementary staged procedures can yield an optimal result. We believe the reconstructive surgeon managing complex facial trauma should strive to incorporate contemporary technologies and techniques into their armamentarium to provide the best patient care.

A face-lift for reconstructive surgery

3D printing and digital modeling improve face transplantation for people affected by facial trauma unrepairable by traditional reconstructive surgery.

Computerized Approach to Facial Transplantation: Evolution and Application in 3 Consecutive Face Transplants

Face transplant (FT) candidates present with unique anatomic and functional defects unsuitable for autologous reconstruction, making the accurate design and transplantation of patient-specific allografts particularly challenging. In this case series, we present our computerized surgical planning (CSP) protocol for FT.
