客观嗓音分析比较CO2激光术与传统剥脱术治疗声带白斑患者的疗效

目的 运用客观嗓音分析比较CO₂激光术与传统剥脱术治疗声带白斑的疗效。 方法 回顾性分析2018年10月至2019年5月住院治疗的确诊为声带白斑患者病历资料,筛选出行CO₂和传统剥脱术患者,CO₂治疗组、传统剥脱术治疗组,对比两组患者手术时间、术中出血量、术后有效率,分别于术后2周、1个月、2个月分析统计两组患者嗓音障碍指数(VHI),采用xion divas的嗓音分析软件,检测手术前及手术后2周、1个月、2个月基频微扰(Jitter)、振幅微扰(Shimmer)、最低音强(SPLmin)、最高基频(F0max)、基频(F0)、最长声音持续时间(MPT)、嗓音障碍指数(DSI)。 结果 CO₂治疗组患者手术时间更短,术中出血量更少;CO₂治疗组有效率高于传统剥脱术治疗组,疗效更佳;两组患者术后1个月、2个月VHI指数均较术前降低,且CO₂治疗组VHI指数低于传统剥脱术治疗组;两组患者治疗后基频微扰、振幅微扰、最低音强均低于治疗前,基频、最长声音持续时间、嗓音障碍指数高于治疗前。 结论 采用CO₂激光术治疗声带白斑较传统的剥脱术疗效更佳,能显著改善患者嗓音。

Evaluation the efficacy of a CO2 laser and traditional exfoliation in the treatment of vocal cord leukoplakia by using objective voice analysis

Objective To evaluate the efficacy of a CO₂ laser and traditional exfoliation in the treatment of vocal cord leukoplakia by using objective voice analysis and to explore the value of objective voice analysis and the effects of the two treatment methods. Methods Medical records of patients with leukoplakia diagnosed in our department from January to February 2018 in 2017 were screened for CO₂ and traditional exfoliation and retrospectively analyzed. The CO₂ treatment group and the traditional exfoliation treatment group were denoted to be the observation and control groups, respectively; the postoperative effective rate was compared between these two groups. The Voice Disorder Index(VHI)was analyzed at 2 weeks, 1 month, and 3 months after surgery. XION DiVAS audio analysis software was used to detect preoperative and surgery 2 Weekly, January, March fundamental frequency perturbation(Jitter), amplitude perturbation(Shimmer), lowest sound intensity(SPLmin),(highest fundamental frequency)F0max, fundamental frequency(F0), longest sound duration(MPT), Voice Disorder Index(DSI). Results Compared to the control group, the observation group had a higher effective rate and a better curative effect. The VHI index in the two groups was lower than that of the preoperative group in the first and third months after operation, and the observation group The VHI index was lower than that of the control group, and the difference was statistically significant. In both groups, postoperative fundamental frequency perturbation, amplitude perturbation, and lowest sound intensity were lower than those before treatment, while fundamental frequency, longest sound duration, and snoring index was higher than those before treatment; a significant difference was noted between the observation group and the control group. The highest fundamental frequency after treatment was not significantly different from that before treatment. Conclusion For objective voice analysis, use of a CO₂ laser for treatment of vocal cord leukoplakia is more effective than the use of traditional exfoliation and can significantly improve the patient's voice.
