Laryngeal Focal Dystonia (LFD) leads to a type of voice with a strained and tense quality which has a neurological origin, affecting the social-emotional realms of the individuals, and their quality of life.
Measure the voice-related quality of life of patients with Adductor LFD pre and post-treatment with Botox, injection followed by voice therapy, using the Voice-Related Quality of Life (V-RQOL).
Prospective study.
Adductor 11 female patients aged between 33 and 74 years with a diagnosis of Adductor LFD were evaluated. All patients underwent a neurological evaluation. Laryngoscopy was performed with both rigid and flexible endoscopes. Speech and Language evaluation followed the Evaluation of Voice Protocol, proposed by Behlau, Pontes (1995). The American V-RQOL measure was utilized.
Statistical analysis demonstrated significant difference (p < 0.05). 81.8% of patients showed higher scores post-Botox, for the social-emotional and physical domain. In the overall V-RQOL scores 72.7% of patients showed greater scores post-treatment.
There was an improvement in the quality of life for these patients post-treatment. The V-RQOL proved to be an efficient tool to measure the treatment outcomes of LFD pre and post botulinum toxin injection.
喉肌张力障碍（LFD）会导致一种声音紧张、紧绷的嗓音，其病因源于神经方面，会影响个体的社会情感领域及其生活质量。
使用与嗓音相关的生活质量（V-RQOL）量表，测量肉毒杆菌毒素注射联合嗓音治疗前后内收型LFD患者与嗓音相关的生活质量。
前瞻性研究。
对11名年龄在33至74岁之间、诊断为内收型LFD的女性患者进行评估。所有患者均接受了神经学评估。使用硬性和软性内窥镜进行喉镜检查。言语和语言评估遵循Behlau、Pontes（1995年）提出的嗓音评估方案。采用美国的V-RQOL量表。
统计分析显示存在显著差异（p < 0.05）。81.8%的患者在接受肉毒杆菌毒素治疗后，在社会情感和身体领域的得分更高。在总体V-RQOL得分方面，72.7%的患者在治疗后得分更高。
这些患者治疗后的生活质量有所改善。V-RQOL量表被证明是一种测量肉毒杆菌毒素注射前后LFD治疗效果的有效工具。
