Endoscope-Assisted Extracapsular Resection of Benign Parotid Tumors Via Temporal and Retroauricular Approach

Objective:To evaluate the feasibility of endoscope-assisted extracapsular resection of benign parotid tumors via temporal and retroauricular approach. Materials and Methods:A total of 12 patients with parotid gland tumors had endoscope-assisted extracapsular resection performed via temporal and retroauricular approach (4 versus 8) between January 2018 and January 2019. Results:All tumors were benign with a median diameter of 2.32 & PLUSMN; 0.49 cm. The mean length of the skin incision was 3.5 & PLUSMN;0.35 cm. The mean operating time 86.7 & PLUSMN; 10.8 minutes. The median blood loss was 30.4 & PLUSMN; 5.94 ml. The median volume of drainage was 27.1 & PLUSMN; 8.88 ml and the duration of drainage was 2 & PLUSMN; 0.71 days. The mean aesthetics scoring assigned by patients was 9.67 & PLUSMN; 0.51. Two patients had numbness of the earlobe and 1 patient developed a transient salivary sialocele. No facial nerve paresis was observed and no tumor recurrence occurred during the follow-up period. Conclusions:The minimally invasive endoscope-assisted extracapsular resection of benign parotid tumors provide both a safe and reliable technique for benign parotid tumors with excellent cosmetic results.
