Objective: This study aimed to evaluate the outcome of benign vocal cord tumors treated using a laryngeal endoscopy under low temperature-controlled radiofrequency and to elucidate the application of a dynamic laryngoendoscopy in the operation. Materials and Methods: 85 patients with benign vocal cord tumors were treated by laryngeal endoscopy under low temperature-controlled radiofrequency from September 2011 to October 2013. A XION electronic dynamic laryngoendoscopy (Germany) was used to observe curative effects 3 months after operation. Wave images were recorded with larynx-wave recording software to analyze tumor characteristics. Results: Among the 85 patients, 81 showed smooth surface of operation wounds without any residue. The mucosal wave was also basically normal. Sound was generally recovered after 1-3 months. Three cases presented improved pronunciation function after the operation, whereas 1 patient with residual tumor at the front of vocal chords underwent another operation after 6 months. Conclusion: Low temperature-controlled radiofrequency exhibited many advantages, including minimal trauma, minimal bleeding, high safety, and few complications. Moreover, treatment of benign vocal cord tumors with a laryngeal endoscopy presented satisfactory outcomes. Therefore, this technology has broad application prospects.
