Abstract:
Objective:To evaluate the feasibility and clinical efficacy of transoral endoscopic-assisted submandibular gland resection with low-temperature plasma knife technology, aiming to establish a scarless surgical approach to meet the patients aesthetic demands. Methods:A retrospective analysis was conducted on 5 consecutive patients with benign submandibular gland pathologies treated by a single surgical team between January 2021 and December 2023. All procedures employed a transoral mucosal incision in the floor of mouth, with 0-degree high-definition endoscope assistance and low-temperature plasma knife for precise dissection and hemostasis. Close postoperative follow-up was performed. A systematic literature review compared surgical approaches regarding critical anatomical landmarks, complication profiles, and scar formation. The clinical efficacy of this technique was summarized and analyzed. Results:Successful transoral endoscopic plasma knife resections were performed for benign submandibular conditions（including neoplasms, chronic sialadenitis, and sialolithiasis）. All operations were completed without conversion to open approach. No permanent lingual nerve or marginal mandibular nerve injuries occurred. Transient lingual hypoesthesia recovered within 2 weeks. During 6-12 months follow-up, there was no recurrence and absence of visible cervical scarring, with 100% patient satisfaction regarding cosmesis. Conclusion:Transoral endoscopic plasma knife resection of the submandibular gland demonstrates procedural safety and technical feasibility. This approach offers significant advantages in minimally invasive access, superior aesthetic outcomes, and accelerated recovery, representing a viable novel alternative for benign submandibular gland disease management.
