    Abstract:
    OBJECTIVES: We aimed to correlate the Vocal Tract Discomfort Scale (VTDS) with the Voice Symptom Scale (VoiSS) for evaluation of patients with dysphonia. In addition, we aimed to compare vocal tract discomfort symptoms in patients with and without self-reported voice problem. STUDY DESIGN: This is a descriptive, cross-sectional, and retrospective study. We analyzed 143 women and 62 men with voice disorders, as confirmed by endoscopic larynx examination. All patients completed the VTDS and VoiSS at vocal evaluation. Descriptive statistics and the Spearman correlation test were applied to all variables. The degree of covariance of variables was noted. The Mann-Whitney U test was used to compare the average number of discomfort symptoms among patients with and without self-reported voice problems. RESULTS: A weak to moderate positive correlation was observed between the average number, frequency, and intensity of comfort symptom and the total score, physical domain score, and limitation domain score of the VoiSS. The vocal tract discomfort symptoms and the emotional domain score of the VoiSS were weakly correlated. Patients with self-reported voice problems had a higher number, frequency, and intensity of vocal tract discomfort symptoms. CONCLUSION: There is correlation between the VTDS and VoiSS scales, with greater references to vocal tract discomfort symptom in patients with self-reported voice problems. Therefore, the discomfort symptoms seem to influence the perception of the impact of a voice problem.
