Role of the sternocleidomastoid muscle flap preventing Frey's syndrome and maintaining facial contour following superficial parotidectomy.

The sternocleidomastoid muscle flap may play a significant role in reducing the incidence of Frey's syndrome and maintaining facial contour after parotidectomy. Patients who underwent superficial parotidectomy from August 1992 to March 1999 were divided into two groups (N = 26). One group had sternocleidomastoid muscle flap reconstruction. A historical cohort study was designed with the two groups being matched for sex, age, pathology, postoperative radiation, date of surgery, and extent of dissection. The starch iodine test was used to evaluate for gustatory sweating, and the Observer Rated Disfigurement Scale was used to assess facial contour and aesthetics. The results of our study suggest that the sternocleidomastoid flap reconstruction following parotidectomy surgery does not alter the incidence of Frey's syndrome and does not significantly improve facial contour and aesthetics.
