A Clinical Study of the Salivary Gland Tumors

타액선 종양의 임상적 고찰

This review is based on the 52 cases of salivary gland tumors treated at the department of surgerym Hallym University Kangdong Sacred Heart hospital during the period from March 1987 to May 1992. There were 43 benign and 9 malignant tumors. Twenty eight(54%) of these cases were located in the parotid gland, 14(27%) in the submandibular gland, the rest of 10 cases(19%) in the minor salivary glands. Female outnumbered male by the ratio 1.6:1. Pleomorphic adenoma was the most common tumor followed by carcinoma and adenolymphoma(Warthin's tumor). The most common presenting symptom in both benign and malignant tumors was palpable mass. However, some patients with malignancy presented symptoms such as pain, facial palsy and dysphagia. Among 9 cases with malignancies 3 cases were found to have metastasis in the regional lymphnodes and two cases had distant metastasis. In majority of benign parotid tumors, superficial parotidectomy was carried out. In three cases of carcinoma of parotid gland with lymphnode metastasis, total parotidectomy with radical neck dissection was done. One case out of two cases of carcinoma of submandibular gland was treated with total excision of the gland with radical neck dissection. There were no postoperative mortalies. Two cases each of facial palsies and wound infections were observed as complication.
