      Summary

      Objectives

      The objective of this study was to compare the recurrence rate and voice improvement of vocal fold leukoplakia (VFL) between microflap resection alone or radiofrequency (RF) Coblation alone.

      Methods

      Patients with VFL intraoperatively treated via microflap resection alone or Coblation alone were enrolled. The recurrence rate, voice assessment, and Videostroboscopic images were compared between the two groups.

      Results

      The recurrence rate at postoperative 12 months was 37.7% (26/69) in the microflap resection group and 7.7% (4/52) in the Coblation group; the difference was significant (P < 0.05). The preoperative and postoperative subjective detection data from the two groups showed significant differences, but the Coblation group recovered better compared to the microflap resection group. No Coblation-related complications were found, including postoperative granulation tissue hyperplasia or anterior commissure adhesion.

      Conclusions

      In patients with vocal cord leukoplakia, RF Coblation had a lower recurrence rate and better voice improvement compared with microflap resection.
