Abstract

We reviewed retrospectively 152 patients' records with salivary gland tumors confirmed histologically at Hanyang University Hospital from Jan. 1984 to Dec. 1993. The results obtained were as follows: 1) Sites of tumors were parotid gland in 102 cases(67%), submandibular gland in 29 cases(19%) and minor salivary glands in 21 cases (14%). 2) 113 cases(74%) were benign. and 39 cases(26%) were malignant. 3) The incidence of benign and malignant tumors were 81% & 19%, 69% & 31% and 48% & 52% in the parotid gland, the submandibular gland and the minor salivary glands respectively. 4) The most frequent histologic types of benign and malignant tumors were pleomorphic adenoma (64%) and mucoepidermoid carcinoma (11%) respectively. 5) The surgical procedures include superficial parotidectomy. total parotidectomy. extended total parotidectomy & neck dissection in the parotid gland. wide excision & neck dissection in the submandibular gland and wide excision, partial maxillectomy & neck dissection in the minor salivary glands. 6) The postoperative recurrence rate were 4.4% in benign tumors and 27% in malignant tumors.
