Abstract：Objective:To evaluate the clinical effect of CO2 laser resection under supported laryngoscope in the treatment of bilateral wide basal polyps of vocal cords.Method:A total of 60 patients diagnosed with bilateral wide basal polyps of vocal cords were selected in Department of Otolaryngology of Beijing Huairou Hospital from July 2022 to May 2024.The patients were randomly assigned to the experimental group(n=30)and the control group(n=30)by using the odd-even number method of medical record number.The control group underwent routine vocal cord polypectomy,while the experimental group underwent CO2 laser resection under supported laryngoscope.The clinical response rate,recurrence rate,postoperative first voice time,voice recovery time,hospital stay,voice disturbance index(VHI),voice function index,and complication rate of the two groups were compared.Result:The clinical effective rate of experimental group was higher than that of control group,and the recurrence rate of experimental group was lower than that of control group,the differences were statistically significant(P<0.05).The first sound time,voice recovery time and hospitalization time were shorter in experimental group than those in control group,the differences were statistically significant(P<0.05).After surgery,the VHI and voice function indexes of both groups were improved,and the longest voice time(MPT)of experimental group was longer than that of control group,the VHI,Jitter and Shimmer of experimental group were lower than those of control group,the differences were statistically significance(P<0.05).The incidence of vocal cord adhesion was 6.7%(2/30)in experimental group and 13.3%(4/30)in control group,there was no significant difference between the two groups(x2=0.740,P=0.389).Conclusion:The effect of CO2 laser resection under supported laryngoscope on patients with bilateral wide basal polyps of vocal cords is significant,the postoperative recurrence rate is low,the postoperative recovery time is short,the voice function is recovered well,and the incidence of vocal cord adhesions will not increase.
