Analysis on Effect of Laser Excision for Vocal Cord Leukoplakia on Recovery of Voice Functions
Objective To explore the effect of laser excision treatment of vocal cord leukoplakia on the recovery of patients'voice functions.Methods Totally 60 patients with vocal cord leukoplakia treated between Oct.2019 and Jan.2024 were selected and randomly divided into a control group and an observation group.While the patients in the control group being given traditional exfoliation surgery,the patients in the surgical group received the CO2 laser resection(in super pulse mode)with a cutting power of 1-2 W and a pulse width time of 0.1 ms.The changes to the patients'voice,including amplitude perturbations and fundamental frequency perturbations were analyzed 2 weeks after the surgery,the voice handicap index(VHI)and surgical efficacy 2 weeks and 1 month after the surgery were compared respectively.Results In both groups,the voice change index increased and the amplitude perturbation and fundamental frequency perturbation decreased after the surgery(P＜0.05).Moreover,the amplitude perturbation and fundamental frequency perturbation in the observation group were lower than those in the traditional exfoliation group(P＜0.05).The subjective VHI decreased after the surgery in both groups(P＜0.05),and the VHI was lower in the surgical group than in the control group(P＜0.05).The postoperative efficacy of the surgical group was better than that of the control group(P＜0.05).No serious complication occurred in either group after the surgery.Conclusions Laser resection for vocal cord leukoplakia plays a positive role in improving the recovery of patients'voice functions.
