Autuor reviewed a total of 77 patients of salivary gland tumors who had been admitted and treated in Yonsei Medical Center during the period from 1965 to 1977, and evaluated their clinical pattern, histologic diagnosis, behavior and type of treatment.
The following results were obtained.
1. Female was affected 1.38 times more than male, and the most frequent age group was 2rd and 3rd decades that occupied more than half(52%) of all salivary gland tumors.
2. The benign tumors had slightly longer duration than malignant tumors, and the
average overwhole duration was 4. 8 years.
3. About 70% of all salivary gland tumors were located in the parotid gland, and 57% of the parotid gland tumors were benign.
Tumors of the submandibular gland occupied about 22% of all salivary gland tumors and 71% of them were benign.
Tumors of the sublingual gland were about 2.6% of all salivary gland tumors and all of them were malignant.
Minor salivary gland tumors occupied about 5.2% of all salivary gland tumors and 50% of them were benign.
4. The most common tumor of the salivary gland was pleomorphic adenoma(benign
mixed tumor) with the incidence of 54.5% of all salivary gland tumors and 55.6% of all parotid gland tumors. The second most common tumor was mucoepidermoid carcinoma, which was 14.3% of all salivary gland tumors.
5. The most frequent type of surgery performed for all salivary gland tumors was local or wide excision comprising about 42% of all procedures, and for the parotid lesions, superficial parotidectomy was the most favoured operative method comprising 35.3% of all parotid gland procedures.
