OBJECTIVE:The aim of this study was to evaluate the outcomes of orthognathic surgery (OGS) in patients with craniofacial microsomia (CFM) who had previously undergone mandibular distraction osteogenesis (MDO). DESIGN/METHODS:A retrospective cohort study was performed including all patients with CFM who were treated with OGS at a single institution between 1996 and 2019. The clinical records, operative reports, and cone beam computed tomography (CBCT) scans were reviewed. CBCT data before OGS (T1), immediately after OGS (T2), and at long-term follow-up (T3) were analyzed using Dolphin three-dimensional software to measure the occlusal cant and chin point deviation. RESULTS:  =  .808). CONCLUSIONS:Within the limitations of this study, these findings suggest that OGS after MDO in patients with CFM can produce stable results.

BACKGROUND:There is a paucity of data on the impact of cytomegalovirus (CMV) serostatus and CMV infection on outcomes in facial vascularized composite allotransplantation. METHODS:This international, multicenter, retrospective cohort study presents data on CMV and basic transplant-related demographics, including pretransplant viral D/R serostatus, and duration of antiviral prophylaxis. CMV-related complications (viremia, disease), allograft-related complications (rejection episodes, loss), and mortality were analyzed. RESULTS:We included 19 patients, 4 of whom received CMV high-risk transplants (D+/R-). CMV viremia was noted in 6 patients (all 4 D+/R- patients and 2 D-/R+), mostly within the first-year posttransplant, shortly after discontinuation of antiviral prophylaxis (median 2 mo). CMV disease occurred in 2 D+/R- patients. The high-risk group experienced relatively more rejection episodes per month follow-up. None of D+/R- patients suffered allograft loss due to rejection (longest follow-up: 121 mo). CONCLUSIONS:D+/R- patients were at increased risk of CMV-related complications. Although a higher number of rejections was noted in this group, none of the D+/R- patients lost their allograft or died because of CMV or rejection. Thus, CMV D+/R- face transplantation can likely be safely performed with prophylaxis, active surveillance, and prompt treatment.

OBJECTIVE:This study aims to develop guidelines for the transfer of patients with isolated craniomaxillofacial (CMF) trauma. METHODS: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 panelist's opinions on transfer guidelines were collected using the modified Delphi process. Consensus was pre-defined as ≥ 90% agreement per statement. RESULTS:After 4 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. CONCLUSIONS:The decision to transfer a patient with CMF 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 CMF transfer guidelines were designed to serve as a tool to improve, and safely streamline, the care of facial trauma patients. Such efforts may decrease the additional healthcare expenditures associated with secondary overtriage while decompressing emergency medical systems and tertiary emergency departments.

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.

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/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

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.

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.
