Gasless Endoscopic Submandibular Gland Excision Through Hairline Approach.

Background: The aim of this study was to evaluate the therapeutic effect of gasless endoscopic submandibular gland excision through hairline approach and the safety, feasibility and practicability of this technique.
Methods: Twenty-five patients with submandibular gland lesions who underwent gasless endoscopic submandibular gland excision through hairline approach at the Department of Head and Neck Oncology of the West China Hospital of Stomatology from May 1 st 2021 to May 31 st 2022 were included in this prospective study. The variables were analyzed statistically with SPSS software version 23.0 (IBM Corp, Armonk, New York, USA).
Results: There was a female predominance (72%), female to male ratio was 2.6. The mean age was 30.6±10.2 years (range: 11 to 52 year). All 25 cases of endoscopic submandibular gland excision through hairline approach were done without conversion to conventional approach. This approach was indicated in 14 cases (56%) for pleomorphic adenoma, 8 cases (32%) for chronic sialadenitis, 2 cases (8%) for adenoid cystic carcinoma, and 1 case (4%) for lymphadenitis. The incision length mean was 4.8±0.4 mm (range: 4 to 5 mm); the operation duration mean was 100.6±39.7 min (range: 51 to 197 min); the intraoperative bleeding mean was 13.2±5.7 ml (range: 5 to 20 ml); the hospital length of stay mean was 4.5±0.8 days (range: 3 to 6 days). The follow-up mean was 10±3.4 months (range: 5 to 16 months). The patients were very satisfied with postoperative cosmetic result (score mean: 9.2±1). No recurrence of disease and complications such as postoperative bleeding, hematoma, nerve damage, skin necrosis, infection, and hair loss occurred.
Conclusions: Gasless endoscopic submandibular gland excision through hairline approach is safe, feasible and practicable, resulting in a very satisfied cosmetic result without significant complications; the intraoperative bleeding is less, the operative field is clear, the operation duration decreases with accumulation of experience.
