目的：评价喉结核患者的发声障碍，并评价言语治疗对患者发声质量的影响。材料和方法：在Evandro Chagas临床研究所、Oswaldo Cruz基金会接受治疗的23例确诊喉结核患者中，有7例接受了为期6个月的语言治疗。在言语治疗前、治疗中及治疗后，对7例患者进行视频喉镜检查和声带分析。结果：23例喉结患者中，女性5例，男性18例，年龄25 ~ 83岁，平均41.3岁。91.3%的喉结核患者存在发音障碍，82.6%的喉结核患者以发音障碍为第一症状。在伴有发音障碍的喉结核患者中，喉结核治疗导致发音障碍消退的患者仅为15.8%。通过对抖动、闪烁、基频变变性、最大发声时间、以及清音和浊音的最大发声时间之比。结论：喉结治疗后，发音障碍的发生率很高。言语治疗改善了患者的声音质量。
Objectives: To evaluate dysphonia in patients treated for laryngeal tuberculosis, and to assess the effect of speech therapy on patients' vocal quality.Materials and methods: Seven of 23 patients with a confirmed diagnosis of laryngeal tuberculosis, treated at the Evandro Chagas Institute of Clinical Research, Oswaldo Cruz Foundation, underwent speech therapy for six months. These seven patients were evaluated by videolaryngoscopy and vocal acoustic analysis, before, during and after a course of speech therapy.Results: The 23 patients with laryngeal tuberculosis comprised five women and 18 men, with ages ranging from 25 to 83 years (mean 41.3 years). Dysphonia was present in 91.3 per cent of these laryngeal tuberculosis patients, being present as the first symptom in 82.6 per cent. In laryngeal tuberculosis patients with dysphonia, laryngeal tuberculosis treatment resulted in dysphonia resolution in only 15.8 per cent. After speech therapy, dysphonia patients had better vocal quality, as demonstrated by statistical analysis of jitter, shimmer, fundamental frequency variability, maximum phonation time, and the ratio between maximum phonation time for voiceless and voiced fricative sounds.Conclusions: Following treatment of laryngeal tuberculosis, the incidence of dysphonia was very high. Speech therapy improved patients' vocal quality.
