Clinical Results of Surgical Treatment in Parotid Tumors

Abstract

Objective: In this study, we aimed to evaluate clinical presentations, histopathological diagnosis, surgical treatment modalities and complications of patients operated for a parotid gland mass. Methods:Medical records of 100 patients who were operated for a parotid gland mass between 2010 and 2016 years evaluated retrospectively.Results and discussion: 49 (49%) of these patients were female and 51 (51%) were male. The mean age of the patients was 47.9. Post-operative histopathologic assessement, 89 of the cases were found to be primary benign, 7 of the cases primary malignant and 4 of the cases secondary malignant. For benign tumors the most common histopathology was pleomorphic adenoma in 45 (45%) patients, and the second was whartin tumor in 32 (32%) patients. Mucoepidermoid carsinoma was seen as the most common primary malign tumor (3 patients). All cases with primary malignancy continue to follow-up visits and the average follow-up period is 37 months. However, all of the cases with secondary malignant parotid tumors were died due to malignancy. Complication ratio was 12% and facial paresis was the most common complication. Conclusion:Subtotal parotidectomy is an adequate and efficient surgical procedure for the benign parotid tumors and complication risk is considerably low when applied carefully. However it may be required complementary total parotidectomy for malignant tumors. The prognosis is very good especially for the primary malign parotid tumors. However, it is not satisfactory for the secondary malign tumors.
