当教室における耳下腺腫易の臨床統計

抄録

There were 43 males and 37 females. The peak incidence was in the sixth decade. The eighty cases consisted of 57 cases of benign tumors and 23 cases of malignant tumors. Rapid growth, fixation, pain and facial paralysis were commonly observed in patients with malignant tumors. Sialogram and ultrasonic examination were useful for differential diagnosis between benign and malignant tumors but were not always conclusive.
Surgery was the first choice for treatment. For benign tumors, extracapsular removal with facial nerve preservation was the principal method. The results were satisfactory without any recurrence. For obvious malignant tumors, radical or extended radical parotidectomy was mainly performed, followed by cobalt irradiation or chemotherapy when necessary. Five of these 23 patients died due to local recurrence or distant metastasis.
