Abstract
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.
