Abstract
Background Reconstruction of the head and neck is dominated by free flaps, and for bone reconstruction by fibula and scapula flaps. However, this choice is sometimes difficult to make in patients who cannot tolerate an extensive and lengthy surgical procedure. In addition, vascular micro-anastomoses are sometimes complicated in patients who have been previously irradiated. Pedicle flaps remain an option and can sometimes be considered as first choice for head and neck reconstruction. Purpose In this study, we describe the feasibility of a split temporal muscle pedicled flap with coronal harvesting for a reconstruction that can reach the midline. Study design sample covariates Ten fresh-frozen human cadaver heads were dissected, and the length of the split flap was noted, followed by the length of the non-split flap. Results The mean length was 155.7 mm (± 20.0) for the split flap, from the point of rotation to the tip of the coronoid process. These results coincide with the tragus-midline distance, which makes it possible to consider reconstruction of the midline, especially the maxilla and the mandible, which has not yet been described in the literature. Conclusions and relevance This technique would then allow a supply of pedicled vascularized bone for loco-regional reconstruction.

Abstract
Osteoradionecrosis (ORN) is a late secondary iatrogenic complication of external radiotherapy for cancers of the upper aero-digestive tract. Despite the systematization of intensity-modulated radiotherapy and its potential for preserving salivary secretion and limiting the dose delivered to the supporting bone, ORN remains a feared and frequent complication. The objective of this literature review was to provide an overview of the management of ORN and to determine the key points that would make it possible to improve patient care. The diagnosis of ORN requires to eliminate tumor recurrence then is based on clinical arguments and imaging by CT or Cone Beam evolving in a chronic mode (more than 3-6 months). The harmonization of its classifications aims to offer comprehensive and multidisciplinary care as early as possible. Primary prevention is based on pre-therapeutic oral and dental preparation, then associated with fluoroprophylaxis if salivary recovery is insufficient and requires supervision of invasive dental care and prosthetic rehabilitation. Semi-automatic contouring tools make it possible to identify doses delivered to dental sectors and guide dental care with personalized dosimetric mapping. Conservative medical treatment is offered at an early stage where innovative medical treatments, highlighted by early studies, could be of interest in the future. In the event of advanced ORN, a non-conservative treatment is then proposed and frequently consists of interruptive mandibulectomy associated with reconstruction by bony free flap, the conditions of implantation remaining to be defined with the support of prospective clinical trials.

Abstract
ABSTRACT After the first face transplantation from woman to woman we performed in our clinic, it was aimed to eliminate the lack of knowledge about the subject in the literature by transferring our experiences and long-term results to the problems we had with the patient. A 20-year-old patient underwent partial osteomyocutaneous facial transplant (22nd facial transplant), which included 2 functional units of the face. The patient had no major problems in the early period and had a good aesthetic appearance. In the postoperative period, the patient ended her social isolation and adopted the transplanted face.In the late period, secondary surgical interventions, management of the problems caused by immunosuppression, and the patient's living in a remote location to our clinic were the difficulties encountered. Six revision surgeries were performed after the transplantation. Due to immunosuppression, opportunistic infections and metabolic problems required intermittent hospitalization. The patient died at the end of 56 months because of complications secondary to immunosuppression.A successful transplant involves the management of long-term problems rather than a successful tissue transfer in the early period. In today's conditions, long-term success can be achieved with a good patient compliance, as well as each team member should take an active role in the team at the transplantation centers. More case series are needed to adapt the standard treatment and follow-up protocols for solid organ transplantations for composite tissue allotransplantations. This will be possible by sharing the results and experiences transparently in the centers where face transplantation is performed worldwide.

Hyperbaric Oxygen Therapy in the Management of Zygomatic Bone Osteomyelitis. J Maxillofac Oral Surg 2021; 20:414-417.

Abstract
Introduction Zygomatic bone osteomyelitis is a rare condition having an incidence of 1.42%. Zygomatic osteomyelitis can be due to haematogenous infection with tubercle bacillus, facial bone fractures or very rarely due to an unknown aetiology like in our case. If surgically managed alone, it would lead to complete loss of zygomatic bone, causing high morbidity to the patient in terms of function and aesthetics like loss of globe support causing dystopia, loss of facial projection causing facial asymmetry. Restoration of facial symmetry and globe support would require extensive procedures such as non-vascular bone grafting or patient-specific implant placement or microvascular bone flap transfer. Materials and Methods Hyperbaric oxygen therapy (HBOT) was used to try and preserve the zygoma by promoting revascularisation. The patient received 100% oxygen at 2.5 absolute atmospheric pressure for 90 min, one session per day for 5 days in a week using a mask system in a multiplace chamber. The patient was reviewed clinically and radiologically after each 5 dives of HBOT sessions. After a total of 30 dives of HBOT, CT examination was repeated. There was partial reconstitution of cortical bone without any additional residual bone lesion. Minimal residual sequestra were noted. At this stage, the patient underwent conservative sequestrectomy in contrast to extensive surgery if HBOT was not contemplated. Conclusion HBOT has the potential to be a very useful adjunct in the treatment of osteomyelitis in head and neck surgery; however, there is a need for carefully designed trials, avoiding methodological bias due to the great variability of patients, infectious agents, antibiotic resistance, host factors, to broaden the evidence of this therapeutic modality.

Abstract
BACKGROUND Facial allotransplantation including the temporomandibular joints may improve the functional outcomes in face transplant candidates who have lost or damaged this joint. METHODS Linear and angular measurements were taken in 100 dry skulls and mandibles and in 100 three-dimensionally-reconstructed facial computed tomographic scans to determine the variability of the temporomandibular joint, glenoid fossa, and mandible. A vascular study was performed in six fresh cadaveric heads, followed by harvest of the face allograft in three heads. Next, four heads were used for mock transplantation (two donors and two recipients). The full facial allograft included four different segments: a Le Fort III, a mandibular tooth-bearing, and two condyle and temporomandibular joint-bearing segments. Statistical analysis was performed using SAS software. RESULTS In only one-third of the skulls, the condylar shape was symmetric between right and left sides. There was a wide variability in the condylar coronal (range, 14.3 to 23.62 mm) and sagittal dimensions (range, 5.64 to 10.96 mm), medial intercondylar distance (range, 66.55 to 89.91 mm), and intercondylar angles (range, 85.27 to 166.94 degrees). This high variability persisted after stratification by sex, ethnicity, and age. The temporomandibular joint was harvested based on the branches of the superficial temporal and maxillary arteries. The design of the allograft allowed fixation of the two condyle and temporomandibular joint-bearing segments to the recipient skull base, preserving the articular disk-condyle-fossa relationship, and differences were adjusted at the bilateral sagittal split osteotomy sites. CONCLUSION Procurement and transplantation of a temporomandibular joint-containing total face allograft is technically feasible in a cadaveric model.

Abstract
PURPOSE In the mandible, the condylar neck vascularization is commonly described as mainly periosteal; while the endosteal contribution is still debated, with very limited anatomical studies. Previous works have shown the contribution of nutrient vessels through accessory foramina and their contribution in the blood supply of other parts of the mandible. Our aim was to study the condylar neck's blood supply from nutrient foramina. METHODS Six latex-injected heads were dissected and two hundred mandibular condyles were observed on dry mandibles searching for accessory bone foramina. RESULTS Latex-injected dissections showed a direct condylar medular arterial supply through foramina. On dry mandibles, these foramina were most frequently observed in the pterygoid fovea in 91% of cases. However, two other accessory foramina areas were identified on the lateral and medial sides of the mandibular condylar process, confirming the vascular contribution of transverse facial and maxillary arteries. CONCLUSIONS The maxillary artery indeed provided both endosteal and periosteal blood supply to the condylar neck, with three different branches: an intramedullary ascending artery (arising from the inferior alveolar artery), a direct nutrient branch and some pterygoid osteomuscular branches.

Abstract
In this report, the authors introduce a rare complication after reduction malarplasty in 2 patients. One patient underwent temporal rhytidectomy and malar osteotomy. The other patient underwent zygoma grinding without osteotomy. Both patients presented malar depression and cheek ptosis after surgery and visited the clinic. Physical examination, cephalometric radiographs, and facial 3-dimensional computed tomography were conducted, which indicated total zygomatic arch bone resorption. After examining the possible causes of the complication, the authors concluded that preserving enough blood supply and performing adequate rigid fixation of the separated zygoma bone are key prevention for bone resorption. This is the first report of total zygomatic arch bone resorption after reduction malarplasty.

Abstract
BACKGROUND Hand transplantation in patients with severe upper extremity burns can be associated with an increased risk of exposure of vessels, tendons, and nerves because of extensive skin and soft-tissue deficit. This study evaluated how to reliably transfer additional extended skin flaps with a standard hand allograft. METHODS Twenty-five upper extremities were used. Sixteen were injected with latex to map the perforating branches of the brachial, superior ulnar collateral, radial, ulnar, and posterior interosseous arteries. Nine hand allografts were procured, injected with blue ink through the brachial artery to assess the perfusion of the skin flaps, and then mock transplanted. RESULTS Sizable perforators from the brachial, superior ulnar collateral, radial, ulnar, and posterior interosseous arteries were used to augment the vascularization of the skin flaps. The average stained area of the medial arm flap was between 85.7 and 93.9 percent. The stained area of the volar forearm flap was the smallest when based on perforators within 6 cm from the wrist crease (51.22 percent). The dorsal forearm flap showed the least amount of staining (34.7 to 46.1 percent). The average time to repair tendons, nerves, and vessels was longer when a single volar forearm-arm flap was harvested (171.6 minutes). Harvest of the allograft associated with a distally based forearm flap and islanded arm flap was the fastest (181.6 ± 17.55 minutes). CONCLUSION Extended skin flaps, based on perforators of the main axial vessels, can be reliably transplanted with a standard hand allograft based on the brachial or axillary vascular pedicle.

Abstract
Methods for harvest of the temporomandibular joint (TMJ) for transplantation may involve several anatomic levels. The authors aim to assess the feasibility and identify challenges with 2 such methods, resuspending the donor condyles from the recipient glenoid fossae and en bloc harvest of the joint and surrounding temporal bone with plate-fixation to the recipient skull base. Two mock face transplantations were carried out using 4 fresh cadavers. Computed tomography imaging was obtained before and after the procedures to assess the technical success of each method. Both techniques were technically successful, allowing for full passive jaw range of motion following graft transfer and appropriate condyle positioning as assessed by computed tomography. En bloc TMJ harvest allowed for transfer of the entire joint without violating its capsule or altering its biomechanics. The authors found this technique better able to avoid issues with size mismatch between the donor mandible and recipient skull base width. When no such mismatch exists, graft harvest at the level of the mandibular condyle is technically easier and less time consuming. Although both methods of TMJ harvest are technically feasible with acceptable immediate postoperative jaw position and range of motion, the en bloc technique allows for more natural jaw function with less risk of postoperative joint immobility by preserving the joint capsule and its ligamentous support.

Abstract
Concomitant temporomandibular joint (TMJ) transplantation is an obvious advancement in the reconstructive armamentarium for face transplantation in scenarios involving TMJ ankylosis. This study investigates the fidelity of mandibular morphology and explores the feasibility of bilateral mandibular condyle transfer in facial vascularized composite allotransplantation. Geometric analysis was performed on 100 skeletally mature maxillofacial computed tomography scans. Exclusion criteria included mandibular trauma and dentoalveolar disease. Parameters measured were posterior height, ramus tilt, anterior height, intercondylar widths, condyle height, coronoid height, interglenoid distances, symphyseal and gonial angles, condyle and glenoid volumes, and condyle shapes. Parameters were compared by gender and ethnicity using χ, independent sample t tests, and one-way ANOVA. Correlation with age was assessed using Pearson correlation coefficients. Bilateral measurements were compared using paired-sample t tests. Mean intercondylar width was 102.5 mm (SD 7.0 mm), anterior height 21.5 mm (5.5), and posterior height 65.3 mm (7.7), Males demonstrate larger geometric parameters, for example, intercondylar width (4 mm mean difference, P = 0.005), anterior height (2.3 mm, P = 0.032), posterior height (5 mm, P = 0.001). Asians demonstrated statistically larger intercondylar width (8 mm difference to Caucasians, P < 0.001). Increased age was associated with greater anterior height, gonial angle, and symphyseal angle; decreased glenoid height; and change in condyle shape. Despite significant disparity of laterality measurements within individuals, posterior height, glenoid, and condyle volumes are equivalent. Mandibular morphology is highly variable. However, transplantation of a facial allograft including the mandible and bilateral condyles is technically and anatomically feasible in patients with concomitant TMJ pathology.
