The aim of surgery for all parotid masses is directed toward total removal of the tumor with adequate safe margins of adjacent normal tissue and preservation of the facial nerve whenever possible. Reconstructive procedures following parotidectomy for benign or low grade malignant lesions are most commonly necessary if soft tissue deficits appear at the angle of the mandible below the earlobe as a major cosmetic deformity. This is a report of Z4 cases with a diagnosis of parotid tumor who were treated using various surgical procedures at Department of Plastic and Reconstructive Surgery, Hanyang University Hospital over the period of 4 years from January, 1983 to December, 1986. Among 24 cases, 11 cases were reconstructed by Sternocleidomastoid muscle flap at the same time that extirpative surgery is outlined. The advantage of Sternocleidomastoid muscle flap is the coverage of the facial nerve, so adhesion between the facial nerve and skin was prevented. Absorption and loss of bulk was not found such as dermofat graft. It was a simple method. Neither donor site defect nor sternocleidomastoid muscle deformity was developed. Sternocleidomastoid muscle flap have been found satisfactory in maintaining filled-out soft tissue hollows with good result cosmetically and functionally.
