EVALUATION OF THE PATIENTS WITH PAROTIS MASS IN THE LAST 7 YEARS: RETROSPECTIVE ANALYSIS OF 211 PATIENTS

Methods: The patients who underwent parotidectomy between 2011-2018 were included in the study. The indications, age and sex distribution, histopathological results and complications were evaluated.

Results: A total of 211 patients who underwent parotidectomy were included in the study. The mean age was 47.64 ± 15.8 (7-82) years. The results of fine needle aspiration biopsy (FNAB) revealed 172 (81.52%) benign, 29 (%13.74) malignancy suspicion, and 10 (% 4.74) malignancy, 178 (84.36%) benign and 33 (15.64%) malignant in surgical pathology. The most common lesion in all parotid masses was pleomorphic adenoma (43.60%). The most common benign lesion was pleomorphic adenoma (51.68%) and the most common malignant tumor was mucoepidermoid carcinoma (27.27%). The tumor was located at right side in 100 (47.39%) and at left side in 111 (52.60%) patients. 31 (14.69%) patients had deep lobe localization or deep lobe extension. 180 (85.31%) of the masses were located in the superficial lobe. Superficial parotidectomy was the most common surgical procedure (84.36%). The concurrent neck dissection was applied to 25 (11.85%) patients. The complications were seen in 30% of the patients and the most common complication was facial paralysis.

Conclusion: The majority of parotid tumors are benign and the most common one is pleomorphic adenoma. Superficial parotidectomy is the most frequently used surgical procedure and its common complication is facial paralysis. Preoperative histopathological diagnosis, location of the mass, tumor stage, facial nerve invasion and the presence of palpable lymph node on the neck play an important role in the planning of the surgery.. In cases of malignant parotid tumors, neck dissection should be added to the treatment. Keywords : Parotid tumors, superficial parotidectomy, pleomorphic adenoma, mucoepidermoid carcinoma
