BACKGROUND:Acute rejection (AR) is a common complication in facial transplant (FT) patients associated with allograft edema and erythema. Our study aims to demonstrate the feasibility of using software-based 3-dimensional (3D) facial analysis to quantify edema as it resolves during/after AR treatment in an FT patient. METHODS:Our patient is a 23-year-old man who underwent a face and bilateral hand allotransplant in August 2020. The Vectra H1 (Canfield, Fairfield, NJ) portable scanner was used to capture 3D facial images at 8 time points between postoperative day (POD) 392 and 539. The images were analyzed with the Vectra Software using a rejection-free image (POD 539) as a control. RESULTS:Edema increased in the periorbital, lower third, and submandibular regions before AR treatment (POD 392-415). At POD 448, total facial edema was reduced to near baseline values in response to plasmapheresis and thymoglobulin (+156.94 to +28.2 mL). The fastest and most notable response to treatment was seen in the periorbital region, while some edema remained in the submandibular (+19.79 mL) and right lower third (+8.65 mL) regions. On POD 465, after the initial improvement, the edema increased but was resolved with steroid use. Facial edema did not correlate with the histopathological evaluation in our patient. CONCLUSIONS:We demonstrated the feasibility of analyzing 3D facial images to quantify edema during/after AR treatment in an FT patient. Our analysis detected edema changes consistent with AR followed by an improvement after treatment. This technology shows promise for noninvasive monitoring of FT patients.

Background/Purpose: APS ACTION is an international Clinical Database and Repository of persistently antiphospholipid antibody (aPL)-positive subjects, collecting demographic, medical history, and aPL data.This study focused on the prevalence of antinuclear antibodies (ANA) in aPL positive patients without a defined concomitant autoimmune disease. The objective of this study was to evaluate potential differences when stratifying patients by ANA, and to better phenotype aPL positive patients.
Method(s): Data from aPL positive patients with or without APS classification criteria were retrieved from the APS ACTION Database. Patients with a diagnosis of systemic lupus erythematosus (SLE) or other connective tissue disease were excluded. Patients were divided in two groups (ANA+ and ANA-), based on ANA status at registry entry. Subsequently, Table 1. Demographic, clinical and serological characteristics of the patients. demographic, clinical (including 1997 ACR SLE classification criteria), and serological data were compared between the two subgroups.
Result(s): 521 aPL-positive patients were included in the study (meanage 52.1+/-13 years, 70% female). Among them, 224 patients were ANA+ and 297 ANA-. Patients characteristics are displayed in Table 1. ANA positivity was significantly associated with previous history of hematologicalmanifestations as a whole, including hemolytic anemia, thrombocytopenia, and leukopenia, (19.3% ANA+ vs. 8.4% ANA-, p < 0.01) and livedo reticularis (15.1% ANA+ vs. 10% ANA-, p < 0.05). A positive association with the number of unexplained fetal deaths beyond 10 weeks of gestation was also noted (p < 0.05), and a trend was observed for lower platelet count, aPL-related nephropathy and arthritis, though these associations were not statistically significant. No significant association was found for extra-criteria manifestations such as haemolytic anemia and history of thrombocytopenia, when considered individually. When sub-analysing the ANA-group, a significant association with any history of arterial thromboses (29.4% ANA+ vs. 38.8% ANA-, p < 0.02) and the number of arterial events was observed (p < 0.01). When evaluating ANA positivity in aPL carriers and primary APS (PAPS) individually, the association between ANA+ and previous hematologic disorder remained significant for both groups, with stronger significance for PAPS patients. In addition, ANA positivity in PAPS patients was significantly associated with livedo reticularis and previous history of small vessel disease (p < 0.05).
Conclusion(s): In this large international cohort, ANA positivity was associated with a higher rate of hematologic manifestations in aPL-positive patients without connective tissue disease. ANA+ patients, especially those with PAPS, showed a tendency toward a higher rate of microvascular manifestations and arthritis. ANA-subjects showed a significantly higher rate of arterial thrombosis, without any other significant association with clinical, serological or demographic data

Although the ethical and technical feasibility of face transplant (FT) has been established, current literature lacks consensus on functional outcomes monitoring for recipients. This systematic review aims to appraise and summarize the current literature on tools used to assess motor functional outcomes in FT. This study complied with the guidelines outlined in the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). On September 15, 2020, two reviewers conducted independent electronic searches using medical literature databases, without language or time frame limitations. Eligibility criteria included studies reporting on the evaluation of motor functional outcomes in face transplant recipients. Of 451 papers found in the literature, 12 fulfilled the study inclusion criteria. The reported tools included clinical scales/examinations, electromyography, optical movement tracking devices, muscle volumetric measurement using magnetic resonance imaging, and software-based video and photo analyses. The frequency of data collection varied from every three months to every year. Publications reporting on motor functional outcomes tracking tools vary broadly and demonstrate a lack of consensus. Although quantitative measurements are desirable, adapted clinical scales are still the current standard of care.

BACKGROUND:Vascularized composite allotransplantation (VCA) has redefined the frontiers of plastic and reconstructive surgery. At the cutting edge of this evolving paradigm, we present the first successful combined full face and bilateral hand transplant (FT-BHT). METHODS:A 21-year-old man with sequelae of an 80% total body surface area burn injury sustained following a motor vehicle accident presented for evaluation. 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 FT-BHT. 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. RESULTS:Combined full face (eyelids, ears, nose, lips, and skeletal subunits) and bilateral hand transplantation (forearm level) was performed over 23 hours on August 12-13th, 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 eight months, the patient is approaching functional independence and remains free of acute rejection. He has significantly improved range of motion, motor power, and sensation of the face and hand allografts. CONCLUSION/CONCLUSIONS:Combined FT-BHT is feasible. This is the most comprehensive VCA procedure successfully performed to date, marking a new milestone in plastic and reconstructive surgery for patients with otherwise irremediable injuries.

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.

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.

BACKGROUND:Facial feminization surgery is composed of a variety of craniomaxillofacial surgical procedures that are increasingly sought after by male-to-female transgender patients and by those seeking feminization of the face. Facial feminization surgery can play a prominent role in alleviating gender dysphoria. In consideration of an observed increase in gender-affirming procedures performed in recent years, a broad knowledge base in the techniques, outcomes, and challenges of facial feminization surgery should be established by surgeons offering these procedures. Our review was designed to critically appraise the current literature and inform future advancements in gender-affirming surgical practice. In addition, we detail a representative case to illustrate the senior author's approach to full facial feminization. METHODS:A comprehensive literature search of the PubMed, EMBASE, and Cochrane databases was conducted for studies published through June 2020 using following the search terms: "Face" OR "facial" OR "craniofacial" AND "Feminization" OR "Feminization Surgery" OR "Gender Reassignment" OR "Gender Affirming Surgery" OR "Gender Confirmation Surgery." Data on procedures, outcomes, patient age, follow-up time, complications, and patient satisfaction were collected. The data were categorized by facial thirds and then further stratified by facial feature. RESULTS:Our search yielded 388 articles. Thirty articles fit our inclusion criteria, and of these, 23 articles were included in the review. We extracted primary data pertaining to 3554 patients with an age range of 18 to 73 who underwent 8506 total procedures. Most of the procedures addressed the upper facial third (hairline, forehead, and brow), comprising 49.1% of total procedures performed. Further categorization by facial feature revealed that the most commonly addressed feature was the forehead (34.6% of procedures), followed by the nose (12.8%) and the chin (12.2%). In studies that used quantitative measures to gauge patient-reported outcomes, satisfaction was high. CONCLUSIONS:Facial feminization surgery seems to be safe, whether it is conducted in a single stage or as a staged procedure. Patients report high satisfaction and better gender congruency after facial feminization procedures. Further research is needed to establish best surgical practice and gauge patient satisfaction beyond the length of average follow-up and determine the frequency with which adjunctive procedures are sought out.

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