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).
