ABSTRACT
Objective To evaluate the clinical effect of preservation of parotid masseter fascia and sternocleidomastoid muscle flap in preventing facial concave deformity and Frey’ s syndrome. Methods 110 patients with parotid gland benign tumor were selected and ran-domly divided into treatment group(56 cases) and control group(54 cases). The treatment group was filled with sternocleidomastoid muscle flap at once and remained parotid masseter fascia in operation. The control group got parotidectomy only. All the cases were followed-up. Re-sults All the cases were successful during a follow-up period of 3~24 months. The treatment group was better than the control group at pre-venting facial concave deformity and Frey’s syndrome (P<0. 01). Conclusion Preservation of parotid masseter fascia and sternocleido-mastoid muscle flap can be the priority selection in improving facial concave deformity and preventing Frey’ s syndrome.
