The Risk Profile of Face Transplant Versus Other Types of Vascularized Composite Allotransplantation Surgery-A...

Vascularized composite allotransplantation (VCA) represents a transformative advance in reconstructive surgery, offering restoration of essential functions and psychological well-being for individuals with severe facial trauma or anomalies. There are different types of VCA. Facial vascularized composite allotransplantation (FVCA) is a complex procedure that carries the potential risk of severe complications in the event of rejection. There is a paucity of research that compares outcomes following FVCA to other types of VCA.

Data were retrieved from the Organ Procurement and Transplantation Network (OPTN) database, which provides comprehensive information on all US organ donation and transplant activities. A search identified 96 eligible VCA cases, consisting of 16 FVCAs and 80 non-FVCA cases that were included in the final analysis.

In facial vascularized composite allotransplantation (FVCA) recipients, the median number of acute rejection episodes was significantly higher compared with non-FVCA patients [5.0 (IQR=0.0-10) versus 0.0 (IQR=0.0-2.0), P =0.0022]. Similarly, the median number of hospitalizations was greater in FVCA patients [3.0 (IQR=0.75-4.0) versus 0.0 (IQR=0.0-1.0), P <0.001]. While the overall complication rates did not differ significantly between groups (44% versus 25%, P =0.14), infectious complications were notably more frequent in FVCA recipients (44% versus 15%, P =0.015).

Facial vascularized composite allotransplantation (FVCA) stands out from VCA procedures due to its heightened immunologic complexity and unique clinical challenges, including high antigenicity from the included skin, presensitized patients, and visible grafts. Facial vascularized composite allotransplantation (FVCA) demands stronger immunosuppression and intensive perioperative monitoring to manage complications. Continued efforts to optimize these strategies are crucial to reduce morbidity and improve outcomes, ensuring FVCA's transformative potential is realized safely and effectively.
