声带息肉围手术期嗓音训练的临床疗效分析

目的　探讨声带息肉患者围手术期行嗓音训练对嗓音恢复的临床疗效。方法　选取72例于我院耳鼻咽喉科行声带息肉手术的患者，随机均分为研究组和对照组，术后对照组仅接受常规治疗，研究组在常规治疗的基础上进行嗓音训练，比较两组患者术后8周的嗓音声学分析结果。结果　术后8周研究组在最长发声时间（maximum phonation time，MPT）、嗓音障碍严重指数（dysphonia severity index，DSI）及最高基频（highest frequency，F0-High）等方面显著高于对照组，差异有统计学意义（P <0.05）；在基频微扰（Jitter）方面显著低于对照组，差异有统计学意义（P <0.05）。两组患者在基频（Fundamental frequency，F0）、最低音强（lowest intensity，I-Low）及振幅微扰（Shimmer）等方面差异无统计学意义（P >0.05）。结论　声带息肉围手术期嗓音训练有助于患者嗓音的恢复。

Clinical efficacy of voice training in the perioperative period of vocal cord polyp

OBJECTIVE To study the clinical efficacy of voice training on voice recovery in patients with vocal cord polyps during perioperative period.METHODS A total of 72 patients with vocal cord polyp were chosen in this study and they were randomly divided into study group and control group. After operation, the control group received routine treatment, and the study group received voice training on the basis of routine treatment. The results of voice acoustic analysis in the two groups were compared at 8 weeks after operation.RESULTS After 8 weeks, the maximum phonation time(MPT), dysphonia severity index (DSI) and the highest frequency(F0-High) of the study group were significantly higher than that of control group (P<0.05). The fundamental frequency perturbation(Jitter) of the study group was markedly lower than that of the control group(P<0.05). There was no statistical difference in the fundamental frequency(F0), the lowest intensity(I-Low) and amplitude perturbation(Shimmer) between the two group (P>0.05).CONCLUSION Voice training in the early postoperative period of vocal cord polyps was helpful to the recovery of the voice.
