Objective To assess the therapeutic efficacy of the low temperaturecontrolled radiofrequency ablation (RFA) on vocal cord polyps. Methods From Sep 2008 to Oct 2010, RFA was applied to treating vocal cord polyps in 85 cases, and all patients were followed up for 3 months postopatively to observe the therapeutic effect via laryngostroboscopy combined with video strobokymography. Results Of all the 85 cases, 81 got smooth vocal cord and normal mucosal wave without residual foci. Their phonatory function got recovered 1 to 3 months after surgery. Phonatory function got improved significantly in 3 patients. One patient with residual polyp received revisional surgery 6 months later and cured. Conclusion With advantages of good effect and safety, minimal invasion and less bleading, the low temperaturecontrolled radiofrequency ablation through laryngeal endoscopic can be widely used to treat vocal cord polyps.
