Comparative study on the therapeutic effects of laser ablation and instrument ablation on vocal cord leukoplakia
Objective To compare the efficacy of CO2 laser ablation and instrument ablation in the treatment of vo-cal cord leukoplakia.Method A retrospective analysis was conducted on 158 patients with vocal cord leukoplakia who un-derwent surgical treatment at Zhejiang Provincial Traditional Chinese Medicine Hospital from May 2017 to June 2022.Ac-cording to the surgical method,patients were divided into a laser ablation group(n=85)and an instrument ablation group(n=73),and the treatment effects,voice function,and vocal cord function were compared between the two groups.Results The cure rate of the laser ablation group was 96.5％,the effective rate was 2.4％,the total effective rate was 97.6％,and the re-currence rate was 1.2％.The cure rate of the instrument detachment group was 94.5％,the effective rate was 1.4％,the total effective rate was 95.9％,and the recurrence rate was 4.1％.Both groups showed improvement in postoperative voice function and vocal cord function(P＜0.05),with the laser ablation group outperforming the instrument ablation group in terms of fun-damental frequency perturbation,amplitude perturbation,severity index of voice disorders,vocal cord vibration symmetry score,and vocal cord mucosal wave score(P＜0.05).Conclusion The overall effect of CO2 laser ablation on vocal cord leuko-plakia is better than instrument ablation,and it has a positive effect on improving the patient's voice.
