Histopathological and Surgical Results of Parotidectomy Patients: Single Center Experience

Abstract

Aim:The aim of this study was to retrospectively evaluate the age, sex, pre-operative fine needle aspiration cytology and incisional biopsy diagnosis, surgical procedure and histopathological results of patients who underwent parotidectomy.Materials and Methods:A total of 67 patients with different parotid gland tumors underwent surgery at Tekirdag Namik Kemal University Faculty of Medicine between 2011-2019 years. The patients’s age, sex, fine needle aspiration cytology and biopsy results, histopathological and postoperative histopathological results and tumor sizes were evaluated. Fine needle aspiration cytology and incisional biopsy results were compared with histopathological data and efficacy of these methods were compared.Results:According to the parotidectomy results of 67 patients, 58(%86.5) were diagnosed as benign (Pleomorphic adenoma, Whartin, Sebaceous lymphadenoma, Sialolithiasis) and nine (13.5%) were diagnosed as malignant. Twenty patients underwent fine needle aspiration cytology and 25 patients underwent incisional biopsy before surgery. Of the 20 patients who underwent FNAC, 16 (80%) were diagnostic and four were non-diagnostic. Of the 25 patients who underwent incisional biopsy, 21 (84%) were diagnostic and four were non-diagnostic.Conclusion:80% of salivary gland tumors that occur in the parotid are benign. The majority of these benign tumors (61-90%) are pleomorphic adenomas. In our study, 86,5% of the parotidectomy cases were benign tumors similar to the literature. 52% of these benign cases are pleomorphic adenoma, the second most common benign tumor is whartin and constitutes 43% of benign tumors.
