Endoscope‐Assisted Resection of Benign Parotid Tumors via Concealed Post‐Auricular Sulcus Incision

Objectives To investigate the feasibility, safety, and effectiveness of endoscopic‐assisted resection of benign parotid tumors via concealed post‐auricular sulcus incision. Methods Between October 2019 and March 2021, eligible patients with diagnosed benign parotid tumors were prospectively included and randomly assigned to two groups: the endoscope‐assisted post‐auricular sulcus incision group (endoscope group) and the conventional Blair “S” incision group (conventional group). Results A total of 45 patients were finally included, including 24 subjects in the endoscope group and 21 subjects in the conventional group. No obvious differences were observed in basic information between these two groups of patients. The surgical incision length in endoscope group patients was 4.0 ± 0.4 cm, which was significantly shorter than that in conventional group patients, 10.3 ± 1.6 cm ( p < 0.001). The total intraoperative blood loss, the first post‐operative day drainage volume, the total post‐operative drainage volume, and the total drainage days were all significantly lower in endoscope group patients than in conventional group patients (all p < 0.05). Among 3 months follow‐ups, no local recurrence or residual tumor were found in both groups of patients, and there were none of them had permanent facial paralysis or parotid fistula. The self‐evaluated appearance satisfaction VAS scores of endoscope group patients were all 0, which was significantly lower than that of conventional group patients, 4.7 ± 1.6 ( p < 0.001). Conclusion Compared with the conventional Blair “S” incision surgery, the endoscope‐assisted resection of the benign parotid tumors via concealed post‐auricular sulcus incision was safe and effective and showed advantages of faster recovery and better self‐assessments of appearance satisfaction.
