Surgical treatment of progressive facial hemiatrophy.

On the basis of multiple clinical observations (64 persons), classification of the defects in progressive facial hemiatrophy is proposed. Three degrees of atrophy of the facial tissues have been pointed out and the methods of surgical treatment depending on them have been described. In degree I-II atrophy, contour plasty using silicone implants and injections of elastosil are preferred. In degree III atrophy, autotransplantation of free skin-muscle and skin-fascia flaps is performed.
