Abstract

Introduction

Vocal cord dysfunction (VCD) is a complex disorder characterized by episodic adduction of the vocal folds during inspiration and expiration, which can lead to dyspnea, wheezing, cough, and acute-onset respiratory distress. Currently, there is a lack of standardized criteria among treating physicians across multiple disciplines, including otolaryngologists, pulmonologists, allergists, and speech and language pathologists, for diagnosis and treatment of VCD, although laryngeal-respiratory retraining therapy (LRT) has emerged as the preferred treatment modality.

Objective

In the present study, we examined the efficacy of LRT in patients presenting with a clinical diagnosis of VCD in the presence and absence of laryngeal adduction on laryngoscopy.

Results

Overall, 74.1% of the cohort showed a response to LRT, of which 62.1% were partial and 12.1% were significant responses. When comparing between patients with and without laryngeal adduction on laryngoscopy, there were no significant differences in the number of sessions of LRT undertaken, mean time to response, and overall response rate between the groups.

Conclusion

Our findings suggest that LRT should be utilized for all patients presenting with symptoms of VCD, even in the absence of laryngeal adduction on laryngoscopy.

声带功能障碍:喉镜下的喉内收能否预测疾病的严重程度和对喉部再训练治疗的反应?
声带功能障碍(VCD)是一种复杂的障碍,其特征是吸气和呼气时声带间歇性内收,可导致呼吸困难、喘息、咳嗽和急性呼吸窘迫。目前,尽管喉呼吸再训练疗法(LRT)已成为首选的治疗方式,但在包括耳鼻喉科医生、肺科医生、过敏症医生、语言和语言病理学家在内的多学科治疗医生中,对VCD的诊断和治疗缺乏标准化的标准。目的在本研究中,我们研究了LRT在喉镜检查中有或没有喉内收的临床诊断为VCD的患者中的疗效。结果总体而言,74.1%的队列患者对LRT有反应,其中62.1%为部分反应,12.1%为显著反应。在喉镜下比较有和没有喉部内收的患者时,两组之间进行LRT的次数、平均反应时间和总反应率没有显著差异。结论我们的研究结果表明,对于所有出现VCD症状的患者,即使在喉镜检查没有喉内收的情况下,也应该使用LRT。
