To date, a radial forearm flap is considered the gold standard for a phalloplasty. However, the visible aesthetic defect to the forearm means a stigmatising scar for male transsexual patients.
The technique described by Coleman based on free fat grafting is one of the therapeutic options proposed to correct the defects caused by scar tissue. This technique is based on an augmentation of volume, while it would also appear to stimulate collagen fibre synthesis, generating an increase in skin thickness and improving tissue quality. Likewise, it has been shown to improve neuropathic pain on the physiopathological basis that the graft’s mesenchymal cells generate a phenomenon of prolonged analgesia through changes in the micro-environment and secretion of substances inducing analgesia.
