Abstract
Objective: To determine the significance of the vocal therapy on life quality improvement in patients with vocal fold nodules. Methods: The study included 20 patients diagnosed with nodules on the vocal cords by otolaryngologists. The age of the respondents ranged from 23 to 56. We performed a subjective assessment of voice with the Voice Handicap Index (VHI) instrument, which encompassed three areas: functional, emotional and physical. This instrument was able to demonstrate the efficacy of local therapy and evaluate the weight of voice problems experienced by the patient. Results: Before the vocal therapy, heavy voice disorder had prevailed in patients, and after the vocal therapy the improvement of voice occurred in all respondents. The statistical significance was below the threshold of 0.05 on the basis of which it can be concluded that there is no statistically significant change between the two measurements. Conclusion: The results of the study showed that the vocal therapy has shown success in patients with vocal fold nodules, which led to their life quality improvement.
