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.
