To analyse the clinical and histopathological characteristics of parotid gland masses at a tertiary referral centre and to compare the results with those cited in literature. The retrospective study was conducted at Adana Numune Training and Research Hospital, Adana, Turkey, and comprised data of patients undergoing parotid surgery between January 2011 and December 2016. They were evaluated in terms of age, gender, surgery method, fine-needle aspiration biopsy results, specimen reports and complications after the surgery for one year. SPSS 20 was used for data analysis. Of 170 parotidectomies, 97(57.1%) had been performed on males and 73(42.9%) on females. There were 145(85.3%) benign and 25(14.7%) malignant tumours. Pleomorphic adenoma 67(39.4%) and Warthin's tumour 56(32.9%) were the two most common benign tumours. Mucoepidermoid carcinoma 7(4.1%) and adenoid cystic carcinoma 6(3.5%) were the two most prevalent malignant tumours. Superficial parotidectomy 133(78.2%) was the main type of surgical intervention. The sensitivity of fine needle aspiration cytology for identifying malignant tumours was 64.71%, the specificity was 100% and overall accuracy of the procedure was 94.92%. Repeated aspirations for sampling different parts of the lesion should be performed on suspicion of malignancy, especially if fine needle aspiration cytology reported pleomorphic adenoma.
