Tumors of the salivary glands were fairly frequent among head and neck tumors. One hundred and three patients (53 male,50 female, average age 54.5 years) were resected surgically in the Department of Otolaryngology, University of Tokushima between 1982 and 1997. The most common type of tumor was pleomorphic adenoma (72.0%), followed by adenolymphoma (21.8%). Preoperative investigations included ultrasound echography, CT, MRI, radioisotope imaging, and sialography, malignancy was correctly diagnosed with 84% sensitivity (false negatives = 3). Seventynine subtotal parotidectomies were performed for a variety of benign and low-grade malignant tumors. Total parotidectomy and neck dissection were required in 3 cases.
