[Efficacy and safety of plasma mode surgery under otoscopic endoscopy to remove tympanic paraganglioma].

The data of 15 surgical cases who underwent type A and type B tympanic paragangliomas resections using a complete transcanal approach under otoscopic endoscopy in plasma mode from January 2021 to February 2024 at Senior Department of Otolaryngology Head and Neck Surgery, the 6th Medical Center of Chinese PLA General Hospital were retrospectively analyzed. Among the 15 patients, 3 were male and 12 were female, with a mean age of (43±11) years. All the cases achieved complete resection of the tumors under the plasma hemostasis mode. The mean operative time was (51±7) min. No sensorineural deafness was observed postoperatively in any of the patients. The current study indicates that the innovative surgical modality for treating various types of tympanic paragangliomas can achieve complete tumor resection with minimal or no bone grinding in an almost bloodless state, demonstrating high efficacy and safety profile.
