Novel surgical technique for full face transplantation

Abstract

Full face transplantation raises a new set of ethical concerns and technical difficulties when compared with partial face transplantation. Previously, it was thought that full face allografts must include bilateral superficial temporal and facial arteries, dictating the need for inclusion of donor parotid glands. This would lead to poor aesthetic outcomes and limit facial nerve coaptation to the level of the main trunk, which often results in synkinesias. The authors present a new approach to full facial allograft recovery based on blood supply from facial arteries alone. This approach eliminates the need to include parotid glands, enabling more distal coaptation of facial nerve branches and targeted innervation of effector muscles. The recovery can be reproducibly performed within 4 hours. Three mock cadaver dissections and three full face transplantations were performed. Donor facial allografts were dissected in cranio-caudal and lateral-to-medial fashion. Individual facial nerve branches were cut medial to parotid glands and coapted to corresponding recipient nerve branches. With the exception of one parotid gland used to add bulk, parotids were generally not included in the allografts. Relevant sensory nerves were coapted. ...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
