title: Outcome analysis of benign vocal cord tumors treated by laryngeal endoscopy under low temperature-controlled radiofrequency.
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.
  
  
  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.
  
  
  CONCLUSIONS
  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.
