Objectives: This study aimed to evaluate surgical feasibility and the aesthetic outcome and frequency of development of Frey's syndrome after superficial parotidectomy with superficial musculoaponeurotic system (SMAS) advancement The study included 23 patients assigned for superficial parotidectomy: 15 men and 8 females with mean age of 36.7+9.7. Surgery was conducted through a modified Blair incision and the skin flap was raised under the periparotid fascia. Facial nerve and its branches and the great auriclar nerve were dissected and preserved. The parotid swelling was dissected and excised with preservation of the parotid duct. The SMAS _flap was dissected sharply from the skin and superficial fascia and then stretched and advanced so as to cover the dissected raw area and fixed to the anterior edge of the stemomastoid. Patients were observed and followed- up for the development of Frey's syndrome and the aesthetic outcome depending on subjective satisfaction with the incision scar and depth of the retromandibular dimple as assessed on a visual analogue scale ranged between 0=unsatisfied and 10=highly satisfied.
