Patients
Participants were 113 patients (48 men, 65 women; median age, 54 [15–81] years) with parotid tumors who underwent partial parotidectomy at the Department of Otorhinolaryngology – Head and Neck Surgery of ***** from 2015 to 2018. We excluded patients whose facial nerve trunk was not identified, who had resection of the facial nerve, and who were undergoing salvage surgery. The median maximum tumor diameter was 25 mm (8–90 mm). Tumor localization was 67:18:28 (superficial lobe:deep lobe:lower pole). Surgery was performed under general anesthesia in all cases. The median operative time was 123 minutes (64–245 minutes), and median blood loss was 10 ml (10–100 ml). Histopathologically, 78 patients had pleomorphic adenoma, 19 had Warthin’s tumor, 6 had cyst, 3 had basal cell adenoma, 3 had acinic cell carcinoma, 2 had adenoid cystic carcinoma, and 2 had mucoepidermoid carcinoma (low malignancy) (Table 1). This study was approved by the Ethics Committee of ***** (No. 1508-2014).
