Facial allotransplantation is a clinical reality, proposed to provide improved functional and aesthetic outcomes to conventional methods of facial reconstruction. Multidisciplinary efforts are needed in addressing not just the surgical and immunological issues but the psychological and sociological aspects as well. In view of this, an international survey was designed and conducted to demonstra...
Material and Methods: Between 2005 and 2015, 32 FTs were performed worldwide. We defined functional outcomes of FT as the ability to smell, breathe, eat, speak, generate facial expressions and experience facial sensation. We performed physical examination, phography/video recordings and imaging-based airway volume measurements on the 7 FT recipients at our institution. We quote functional outco...
Craniofacial birth defects occur in 1 out of every 700 live births, but etiology is rarely known due to limited understanding of craniofacial development. To identify where signaling pathways and tissues act during patterning of the developing face, a 'face transplant' technique has been developed in embryos of the frog Xenopus laevis. A region of presumptive facial tissue (the "Extreme Anterio...
A 47-year-old man developed a complete facial nerve palsy secondary to non-cholesteatomatous suppurative otitis media. At operation, this was seen to be due to destruction of the nerve from halfway along the horizontal segment to a point just distal to the second genu. The history of recent renal transplantation and subsequent immunosuppression was judged to be significant in the pathogenesis o...
The face and scalp define functionally and aesthetically important units. Traumatic deformities of the head and neck region resulting from burn injuries, gunshot wounds, or ablative tumor surgeries may be presented as a single defect, such as of the skin, the subcutaneous tissue, or the muscle, or as a combination defect involving all three units. The optimal reconstruction of these specialized...
The pioneering Times Although the concept of Transplantation could be traced back as early as Saint Cosmas and Damian most famous miracle, grafting of a leg to replace a patient’s ulcered leg, it is not before the 50’s that it entered reality. Important steps were made before, from sewing vessels to understanding the basis of the major histocompatibility complex (MHC) in mice (Snell, 1986). Thi...
