Fifty parotid tumors were resected surgically during the past five years between 1994 and 1998 in the Department of Otolaryngology, Tachikawa Hospital. There were 27 males and 23 females. The peak incidence was in the fifth decade of life and the average age was 49 years. 41 tumors were benign and 9 were malignant. A pleomorphic adenoma was noted in 50% of the parotid tumors, followed by Warthin's tumor (22%).
Facial nerve palsy occurred in 36% of the patients after operation. Most of the facial nerve palsies after operation recovered in 3 months. Mandibular branch palsy was noted most often.
