Abstract: Objective To explore the feasibility of resecting benign gloss-epiglottis lesions assisted with video laryngoscope and radio frequency plasma system, and to summarize the indications and operative methods. Methods Patients with benign gloss-epiglottis lesions were prospectively enrolled in this study during Jan. 2014 and June 2015. The lesions were resected with assist of video laryngoscope and radiofrequency ablation system in patients with lingual base papilloma, lingual tonsillar hypertrophy and epiglottis cyst. All patients were followed up, and therapeutic effects and complications were recorded. Results A total of 71 patients were enrolled, including 44 with epiglottis cyst, 17 with lingual base papilloma and 10 with lingual tonsillar hypertrophy. After general anaesthesia with tracheal intubation stabilization, all operations were conducted with assist of video laryngoscope and radiofrequency ablation system. All patients recovered well, except 2 patients who developed tardive postoperative hemorrhage. No other complications occurred. During the 6-18 month follow-up, no recurrence was observed. Conclusions Lesion ectomy with assist of video laryngoscope and radiofrequency ablation system is safe, simple, mini-invasive, and effective, which offers good exposure and wide field, and achieves a high local control and low surgical complication rate.
