Abstract
Objective:The aim of this study is to evaluate the efficacy of CO2 laser and CO2 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 CO2 laser group and CO2 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 CO2 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 CO2 laser alone.
