Abstract：
OBJECTIVE: The aim of the study is the clinical investigation of a patient with a vocal fold polyp, and the visual, acoustical, perceptual, and self-report changes before and after using the cricothyroid visor manoeuvre (CVM).
METHODS: A 48-year-old female university professor, gynecologist, and obstetrician with a history of laryngopharyngeal reflux and a left vocal polyp participated. Treatment was provided in 10 sessions. Pre- and post-treatment audio recordings of sustained vowels, selected sentences, and connected speech samples were submitted to auditory-perceptual and acoustical analysis to assess the effects of the two-treatment program. Also, laryngoscopic images, perceptions by the patient about her voice quality and quality of life before and after therapy were assessed.
RESULTS: Improvements in acoustic parameters were obtained especially in perturbation and CCPS parameters. The overall voice quality scores on the CAPE-V were moderate before therapy and became mild after therapy. Laryngoscopy images demonstrated improvement in the glottis closure configuration in two phases (open and close) in pre- and post- CVM therapy and a decrease in polyp size. The patient had improvement in VAS, IVQLP, and VRQOL scores.
CONCLUSIONS: The CVM therapy used in the study resulted in positive changes in acoustic and perceptual-auditory aspects of voice production, self-report, and QOL for the patient. The CVM approach appears to have been effective for this case in decreasing the polyp size or its regression or for vocal adaptation.

摘要：
目的：本研究的目的是对患有声带息肉的患者进行临床调查，和视觉，声学,感性的，并自我报告使用环甲护目镜动作（CVM）前后的变化。
方法：一位48岁的大学教授，妇科医生,有喉咽反流和左声带息肉病史的产科医生参加。在10个疗程中提供了治疗。持续元音的治疗前后录音，选定的句子，并将连接的语音样本提交给听觉感知和声学分析，以评估两种治疗方案的效果。此外，喉镜图像,评估患者对治疗前后嗓音质量和生活质量的看法.
结果：获得了声学参数的改善，尤其是在扰动和CCPS参数方面。CAPE-V的总体语音质量评分在治疗前为中等，治疗后变得温和。喉镜图像显示，在CVM治疗前后的两个阶段（打开和关闭）声门闭合配置有所改善，息肉大小减小。患者的VAS有所改善，IVQLP,和VRQOL分数。
结论：研究中使用的CVM疗法导致了声音产生的声学和感知听觉方面的积极变化，自我报告,以及患者的生活质量。CVM方法似乎对这种情况有效，可以减少息肉的大小或消退或声音适应。
