Abstract

Abstract: PURPOSE: To review the clinical data of patients undergoing operation, in order to summarize the incidence, proportion, clinical examination and diagnostic methods of parotid tumors. METHODS: Eight hundred and ninty-six cases of parotid gland tumors were collected from 2008 January to 2015 July from department of oral and maxillofacial surgery in Shengjing Hospital of China Medical University. A retrospective study of the clinical data was carried out, including age, gender, tumor location, diagnostic methods and pathological results. RESULTS: In 896 patients with parotid gland tumor, 432 were male, 464 were female, the ratio was 1:1.07; 431 cases were on the left side, 454 cases were on the right side, 11 cases were bilateral; The proportion of parotid tumor was higher in patients aged 31 to 70 years old. 786 cases were benign, 110 cases were malignant, the ratio of benign to malignant was 7.15:1. Pleomorphic adenoma, Warthin tumor and basal cell adenoma were the most common types of benign tumors, while mucoepidermoid carcinoma, acinic cell carcinoma and adenoid cystic carcinoma accounted for the most of malignant tumors. CONCLUSIONS: The pathological types of parotid gland tumor are complicated. Clinical examination and imaging features are helpful to diagnosis. The accuracy is high in diagnosis of parotid gland tumor by frozen section, which is useful to assist making treatment plan.
