Epidemiologic and Clinical Manifestations of Parotid Masses

Abstract

Parotid tumors are among the most common tumors. One of the main treatments for these tumors is surgery, which is directly related to the surgeon's experience, and the main postoperative complications include damage to the facial nerve. Therefore, the aim of the present study was to investigate the epidemiology and clinical manifestations of parotid masses. Materials and Methods: In this cross-sectional study, 154 patients with parotid tumors referred to ENT clinics of Tabriz University of Medical Sciences were studied. Patients' information was extracted from the archived clinical file. Patient information including age, sex, type of surgery (superficial or total parotidectomy), type of pathology, type of tumor (pleomorphic adenoma, Wartin tumor, cyst, inflammation or reactive lymph nodes and schwannoma), benign or malignant tumor, early complications of Such as transient facial nerve palsy, wound infection, sialocell, and soft-tissue anesthesia were recorded in a researcher-designed data collection form. Results: The mean age of the studied patients was 46.75±13.60 years and 51.3% of the patients were female. In addition, the highest frequency of tumors was in the age group of 41 to 60 years and there was no difference in terms of gender in the prevalence of tumors. The highest frequency of parotid tumors in the present study was related to pleomorphic adenoma (77.9%) and 98.7% of tumors were benign, of which pleomorphic adenoma is the most common benign tumor. The most common clinical manifestations of parotid tumors were mass in the cheek area with a frequency of 99.4% and the most common risk factors for parotid tumors in patients were smoking (33.1%) and then hair dye (22.7%).
