Near-total human face transplantation for a severely disfigured patient in the USA

BACKGROUND Multiple reconstructive procedures are common for the reconstruction of complex facial deformities of skin, soft tissues, bony structures, and functional subunits, such as the nose, lips, and eyelids. However, the results have been unsatisfactory. An innovative approach entailing a single surgical procedure of face allograft transplantation is a viable alternative and gives improved results. METHODS On Dec 9, 2008, a 45-year-old woman with a history of severe midface trauma underwent near-total face transplantation in which 80% of her face was replaced with a tailored composite tissue allograft. We addressed issues of immunosuppressive therapy, psychological and ethical outcomes, and re-integration of the patient into society. FINDINGS After the operation, the patient did well physically and psychologically, and tolerated immunosuppression without any major complication. Routine biopsy on day 47 after transplantation showed rejection of graft mucosa; however, a single bolus of corticosteroids reversed rejection. During the first 3 weeks after transplantation, the patient accepted her new face; 6 months after surgery, the functional outcome has been excellent. In contrast to her status before transplantation, the patient can now breathe through her nose, smell, taste, speak intelligibly, eat solid foods, and drink from a cup. INTERPRETATION We show the feasibility of reconstruction of severely disfigured patients in a single surgical procedure using composite face allotransplantation. Therefore, this should be taken in consideration as an early option for severely disfigured patients. FUNDING None.

Three Patients with Full Facial Transplantation

Unlike conventional reconstruction, facial transplantation seeks to correct severe deformities in a single operation. We report on three patients who received full-face transplants at our institution in 2011 in operations that aimed for functional restoration by coaptation of all main available motor and sensory nerves. We enumerate the technical challenges and postoperative complications and their management, including single episodes of acute rejection in two patients. At 6 months of follow-up, all facial allografts were surviving, facial appearance and function were improved, and glucocorticoids were successfully withdrawn in all patients.

First U.S. Near-Total Human Face Transplantation: A Paradigm Shift for Massive Complex Injuries

Background: Severe complex facial injuries are difficult to reconstruct and require multiple surgical procedures. The potential of performing complex craniofacial reconstruction in one surgical procedure is appealing, and composite face allograft transplantation may be considered an alternative option. The authors describe establishment of the Cleveland Clinic face transplantation program that led them to perform the first U.S. near-total face transplantation. Methods: In November of 2004, the authors received the worlds first institutional review board approval to perform a face transplant in humans. In December of 2008, after a 22-hour operation, the authors performed the first near-total face transplantation in the United States, replacing 80 percent of the patients traumatic facial deficit with a composite allograft from a brain-dead donor. This largest, and most complex, face allograft in the world included over 535 cm2 of facial skin; functional units of full nose with nasal lining and bony skeleton; lower eyelids and upper lip; underlying muscles and bones, including orbital floor, zygoma, maxilla, alveolus with teeth, hard palate, and parotid glands; and pertinent nerves, arteries, and veins. Immunosuppressive treatment consisted of thymoglobulin, tacrolimus, mycophenolate mofetil, and prednisone. Results: The patient tolerated the procedure and immunosuppression well. At day 47 after transplantation, routine biopsy showed rejection of the graft mucosa without clinical evidence of skin or graft rejection. The patients physical and psychological recovery went well. The functional outcome has been excellent, including optimal return of breathing through the nose, smelling, tasting, speaking, drinking from a cup, and eating solid foods. Conclusion: The functional outcome thus far at 8 months is rewarding and confirms the feasibility of performing complex reconstruction of severely disfigured patients in a single surgical procedure of facial allotransplantation.

The technical and anatomical aspects of the world's first near-total human face and maxilla transplant

OBJECTIVE To discuss the technical and anatomical analysis and design of an osteocutaneous allograft transplant incorporating the donor maxilla and the execution of the operative protocol during the transplant. METHODS The Cleveland Clinic reported the worlds first successful combined face and maxilla transplant in December 2008. Unlike the 3 prior face transplants, this surgical procedure was done as a salvage operation in a patient who had undergone 23 major reconstructive procedures. The additional complexity due to significant postoperative scarring and recipient vessel depletion presented a unique challenge in this case. The extensive 3-dimensional losses of facial structures in multiple tissue planes required a Le Fort III osteomyocutaneous allotransplant incorporating the donor maxilla. RESULTS We report the first successful transfer of a complete bony framework and soft-tissue envelope. The allograft has shown excellent integration and no long-term rejection. The traditional conception based on anatomical studies suggested that this transfer would require independent dissection of the internal maxillary vascular system. This was not required in our patient whose allograft was based solely on the facial arterial system and its arcades. CONCLUSIONS Successful near-total face and maxilla allograft transplant can be accomplished based on the facial arterial system and its arcades. This presents a novel method for reconstructing massive facial injuries with significant involvement of the facial skeleton.

Outcomes of vascularized bone graft reconstruction of the mandible in bisphosphonate-related osteonecrosis of the jaws†‡

Analysis of outcomes of vascularized flap reconstruction in patients with advanced mandibular osteoradionecrosis.

OBJECTIVE: To examine outcomes of vascularized bone flap reconstruction of end-stage osteoradionecrosis of the mandible. STUDY DESIGN: Case series with planned data collection. SETTING: Tertiary care academic hospital. SUBJECTS: Patients with end-stage radiation-induced osteoradionecrosis (ORN) refractory to conservative therapy with wound complications including chronic infections, fistula formation, and pathologic fracture were included. RESULTS: Outcomes of 33 patients were prospectively collected and analyzed, making this the largest series on this subject in the literature and the only one with planned data collection. Data on preoperative variables including radiation dose, sub-site location, treatment date, and prior therapy, along with intraoperative issues and postoperative outcomes, were tracked and are presented. ORN was seen to develop in a bimodal distribution based on the timing of interval surgical intervention. The extent of local soft tissue injury often required the use of contralateral recipient vessels. Local wound complication rates were higher than that seen in primary reconstructions. CONCLUSIONS: Successful reconstruction was achieved in all of the patients in this series. Long-term resolution of infectious complication and disease resolution was seen in 91 percent of the patients in this series.

Saddle Nose Deformity Reconstruction With a Split Calvarial Bone L-Shaped Strut

OBJECTIVE To describe a technique for creation of a split calvarial bone L-shaped strut that provides dorsal support while increasing tip projection in patients with substantial septal saddle nose deformities from various underlying inflammatory conditions and surgical resection. METHODS Case series and review of the literature. RESULTS Fifteen patients underwent nasal reconstruction at our institution using the split calvarial bone L-shaped strut technique with postoperative follow-up to 36 months (range, 9-36 months). The causes of septal perforation leading to saddle nose deformity included cocaine use, infection, sarcoidosis, malignant lesion, iatrogenic causes, and Wegener granulomatosis. All cases resulted in an augmented, straightened nasal dorsum and increased tip projection. Results were maintained throughout follow-up with no evidence of graft infection, resorption, or migration. CONCLUSIONS The split calvarial bone L-shaped strut provides dual benefits of dorsal support and increased tip projection. Numerous techniques have been discussed for dorsal augmentation with varied success; however, the long-term maintenance of this graft in patients with severely compromised vascularity owing to underlying inflammatory conditions such as Wegener granulomatosis highlights its presumed advantages. The procedure can be performed using the external rhinoplasty approach, obviating the need for radix incisions for plating or intranasal mucosal incisions. These advantages make the L-shaped strut technique excellent for nasal reconstruction in patients with substantial septal saddle nose deformities regardless of cause and duration of defect.

Swallowing Outcomes After Microvascular Head and Neck Reconstruction: A Prospective Review of 191 Cases

Background: The use of microvascular free tissue flaps tailored specifically to the ablative surgical defects has allowed precise anatomic reconstructions to be performed and, in turn, has improved patient outcomes. We report here the postoperative swallowing outcomes of patients undergoing microvascular reconstructions for a range of head and neck defects at the Cleveland Clinic.

Prospective Analysis of Outcomes and Complications of 300 Consecutive Microvascular Reconstructions

OBJECTIVE To prospectively follow up patients requiring microvascular reconstruction of head and neck defects to determine preoperative factors predictive of surgical complications. METHODS A prospectively collected database comprising 300 consecutive microvascular head and neck reconstructions performed by a single surgeon (D.S.A.) in a tertiary care hospital over a 6-year period was reviewed in a retrospective manner. Data collected included preoperative medical and surgical history (presence of documented cardiac disease, diabetes mellitus, and hypertension) and previous cancer treatment (surgery or radiation therapy). Postoperative data, including early or late complications, hematocrit during hospitalization, and functional status, were also collected. A multiple linear regression was used to identify predictors of surgical complications and secondarily crossed to determine the strength of the prediction. Statistical significance was set at P = .05. RESULTS Patients were stratified into 4 groups based on (1) previous radiation therapy, (2) previous surgery, (3) no previous radiation therapy or surgery, and (4) both previous radiation therapy and previous surgery, with an increased predictability of complications with both. Diabetes also added to the predictability of complications, with a smaller effect. Cardiac disease and hypertension were not predictive. CONCLUSIONS Previous radiation therapy and surgery are positive predictors for wound complications after microvascular reconstruction. Diabetes may add further risk in this setting.

Total parotidectomy defect reconstruction using the buried free flap

OBJECTIVE 1) Present an alternative method of total parotidectomy with or without neck dissection defect reconstruction that results in improved cosmesis. 2) Describe applications of free tissue transfer in parotidectomy defect reconstruction. STUDY DESIGN Case series with chart review. SETTING Two tertiary-care medical centers. SUBJECTS AND METHODS A two-institution retrospective review from 2002 to 2009 was conducted for buried free flaps utilized in reconstruction of defects from total parotidectomy with or without neck dissection. Patients with temporal bone or skin resections were excluded. Demographic information, tumor characteristics, surgical interventions, flap details, and adjunctive facial reconstructive techniques were recorded. Postoperative cosmetic results were evaluated by patient and physician satisfaction. RESULTS Eighteen patients with a mean age of 57.4 years underwent flap reconstruction. Total parotidectomy was performed in all cases, 11 cases required facial nerve sacrifice, and 14 cases included neck dissection. The anterolateral thigh flap was the most often utilized free flap. Mean flap area was 65.5 cm2. Adjunctive static facial reanimation was employed in eight patients. All flaps survived. Ten patients underwent adjuvant radiation. Free flap reconstruction resulted in cosmetic patient and surgeon satisfaction, despite adjuvant radiation therapy. CONCLUSION Free flap reconstruction of total parotidectomy (with or without neck dissection) defects is safe and effective. It does not preclude adjunctive facial reanimation and provides sufficient tissue bulk to match the contralateral facial contour despite radical resections and adjuvant radiation therapy in most cases.
