Retrospective Study on Clinico-Pathological Presentations and Complications of Parotidectomy

Abstract

Introduction Salivary gland tumors are rarely seen. It constitutes approximately 3% of all head-neck tumors. 75-80% of these tumors originate from the parotid gland. In this study, 98 patients who underwent parotidectomy in a tertiary otorhinolaryngology clinic were analyzed retrospectively, the frequency of different pathologies and our treatment modalities for parotid masses are presented in the light of current literature. Materials and Methods In this study, 98 patients who underwent parotidectomy in our clinic between 2011 and 2018 were retrospectively analyzed, the frequency of different pathologies, our treatment approach, and complications of treatment for parotid masses are presented in the light of current literature. Results The mean age was 48 years (between the range of 7-82 years). 41 cases were female and 57 cases were male. In the results of FNAB, there were 65 (66%) benign cases, 28 (29%) malignancy suspects and 5 (5%) malignant cases, 68 (69%) benign cases, and 30 (31%) malignant cases in surgical pathologies. The most frequent lesion of all parotid masses was pleomorphic adenoma (24%). The most common benign lesion was pleomorphic adenoma (35%) and the most frequent malignant tumor was mucoepidermoid carcinoma (27%). The most common surgery type was superficial parotidectomy (82 cases). The most common complication was marginal mandibular nerve paresis (6). Conclusion The treatment modality of the parotid tumors varies from case to case according to the nature of the tumor and extension.
