초록
After thyroidectomy, some patients who show normal vocal cord movement still complain of subjective voice problems, which could lead to a decrease in quality of life related to communication. This study aims to investigate the effectiveness of a newly designed voice therapy applying neck exercise and semi-occluded vocal tract exercise (SOVTE) to improve voice problems after thyroidectomy without neurological injury. For this purpose, voice therapy was randomly assigned to 10 women who received thyroidectomy. Acoustic analysis [fundamental frequency, jitter, shimmer, noise-to-harmonics ratio, min Voice Range Profile (VRP), max VRP, VRP] was performed before and after surgery and immediately after voice therapy to compare voice changes. The study showed a statistically significant increase in max VRP and VRP after voice therapy compared to before surgery. These results suggest that the voice therapy methods in this study effectively improve a major symptom of voice problems after thyroidectomy, specifically the reduction in the high-frequency range. However, this study was limited in the number of s participants and did not control for the type of surgery. Therefore, further research utilizing larger sample sizes and controlled variables is needed to investigate the long-term effects of voice therapy.
