Dermis-fat graft after parotidectomy to prevent Frey's syndrome and the concave deformity.

Dermis-fat grafts were performed on 7 patients at the time of parotidectomy to prevent Frey's syndrome and the characteristic concave deformity. Only 1 patient demonstrated postoperative Frey's syndrome, and 1 demonstrated a slightly concave deformity due to fat absorption. Although other barrier materials have been reported to achieve success in preventing gustatory sweating, our method simultaneously corrects the associated deformity of facial contour as well.
