Abstract：
BACKGROUND: Regarding human coronavirus, the severe acute respiratory syndrome coronavirus 2 pandemic, the novelty of disease, and consequently the lack of studies, the etiology of dysphonia in patients with coronavirus disease 2019 is still unknown and needs to be investigated. The purpose of the current study is to investigate the effect of a new manual therapy technique, cricothyroid visor maneuver, on muscle tension dysphonia symptoms for a patient who had experienced dysphonia symptoms due to the coronavirus disease 2019 infection.
METHODS: A 55-year-old retired Iranian teacher who was diagnosed with muscle tension dysphonia by an otolaryngologist participated in this study. Fifty days before being referred to an otolaryngologist, he was diagnosed with coronavirus disease 2019 on the basis of the results of a standard laboratory test, namely real-time polymerase chain reaction. Treatment was provided in ten sessions. Pre- and post-treatment audio recordings of sustained vowels, selected sentences, and connected speech samples were submitted for auditory perceptual and acoustic analysis to assess the effects of the treatment program. Also, videolaryngostroboscopy voice quality perceptions by the patient, both before and after therapy, were assessed. The reduction in all features of the Consensus Auditory-Perceptual Evaluation of Voice was observed. The results of acoustic assessment showed that jitter (35.13%) and shimmer (20.48%) decreased; moreover, the harmonics-to-noise ratio (1.17%), cepstral peak prominence smoothed (28.53%) and maximum phonation time (15.5%) increased after treatment sessions. The scores of four parameters of Stroboscopy Examination Rating Form (SERF) form changed after cricothyroid visor maneuver therapy. Also, the visual analog scales score at the pre-treatment assessment was 40, and increased to 90 at the post-treatment assessment.
CONCLUSIONS: The effectiveness of cricothyroid visor maneuver therapy on dysphonia associated with coronavirus disease 2019 was investigated in the current study. This case study has highlighted chronic dysphonia after coronavirus disease 2019 infection, and suggests that the cricothyroid visor maneuver therapy approach may have positive outcomes for patients with muscle tension dysphonia with this background.

摘要：
背景：关于人类冠状病毒，严重急性呼吸系统综合症冠状病毒2大流行，疾病的新颖性，因此缺乏研究，2019年冠状病毒病患者的发音障碍的病因仍然未知，需要进行调查。本研究的目的是探讨一种新的手法治疗技术的效果,环甲护目镜动作，关于一名因2019年冠状病毒感染而出现发音障碍症状的患者的肌张力发音障碍症状。
方法：一名55岁的伊朗退休教师被耳鼻喉科医生诊断为肌肉紧张性发声障碍。在转诊给耳鼻喉科医生前50天,根据标准实验室检查的结果，他被诊断出患有2019年冠状病毒病，即实时聚合酶链反应。在十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，和连接的语音样本被提交用于听觉感知和声学分析，以评估治疗方案的效果。此外，视频喉镜检查患者的语音质量感知，治疗前后,被评估。观察到声音的共识听觉感知评估的所有特征都减少。声学评估结果表明，抖动(35.13%)和微光(20.48%)降低；此外，谐波噪声比(1.17%)，治疗后，倒谱峰突出平滑（28.53％），最大发声时间（15.5％）增加。环甲护目镜动作治疗后，频闪镜检查评级表（SERF）表的四个参数得分发生变化。此外，治疗前评估时的视觉模拟量表评分为40分,治疗后评估时增加至90分.
结论：本研究调查了环甲护目镜手法治疗2019年与冠状病毒疾病相关的发音障碍的有效性。这一案例研究强调了2019年冠状病毒感染后的慢性发声困难，并提示环甲护目镜手法治疗方法对这种背景下的肌张力发声障碍患者可能有积极的结果。
