Frey syndrome: treatment with temporoparietal fascia flap interposition.

There is a 10% to 48% reported incidence of clinically significant gustatory sweating after parotid surgery or injury. Various medical and surgical treatments have been used in the attempt to treat this socially embarrassing condition. These treatments are not always effective and often have unwanted risks and adverse effects. They also do not address the post-parotidectomy defect. Prevention of Frey syndrome and correction of the postoperative contour deformity after parotidectomy have recently been achieved by interposition of temporoparietal fascia flap between the parotid gland and the cheek skin flap at the time of parotidectomy. This article presents the first report (to our knowledge) of an established case of Frey syndrome being treated with temporoparietal fascia flap interposition.
