Abstract
Objective:The aim of this study is to evaluate the efficacy of CO2 laser and CO2 laser combined with microsuture in the treatment of bilateral sessile polyps of vocal cords. Methods:Forty-eight patients with bilateral sessile polyps of vocal cords were randomly divided into CO2 laser group and CO2 laser combined with microsuture group. The surgical effect of each group and the difference between the two groups were evaluated by subjective score and objective voice analysis. Results:One month and three month after operation, Jitter, Shimmer, dysphonia severity index（DSI）, the maximum phonation time（MPT）, the parameters of G and voice handicap index（VHI-10） in the two groups were significantly different from pre-operation（P<0.05）. There were also significant differences in Jitter, Shimmer, DSI and MPT between the two groups one month and three month after operation respectively（P<0.05）. But no significant differences of the parameters of G and VHI-10 was noted between two groups（P>0.05）. The incidence of postoperative vocal cord adhesion was 8.3% and 0 in two groups respectively, and there was no significant difference between the two groups（P>0.05）. Conclusion:The CO2 laser combined with microsuturing technique can effectively improve the voice quality of patients with bilateral wide-based vocal cord polyps, and the effect is better than that of using CO2 laser alone.
