1. Removal of the thyroid gland often leads to vocal problems due to potential nerve damage, affecting voice quality and causing symptoms like hoarseness and vocal fatigue. 2. Vocal dysfunction post-thyroidectomy significantly impacts patients’ daily lives, affecting communication and social interactions. 3. Semi-occluded vocal tract exercises (SOVTE), such as straw phonation and lip trills, are effective in improving voice outcomes by enhancing vocal efficiency and minimizing vocal fold stress. 4. The case study presented Preliminary evidence from a single subject showed positive changes in vocal behavior, including improved intensity, frequency, and quality of voice after SOVTE therapy. 5. The study suggests that SOVTE could be beneficial in enhancing voice quality for thyroidectomy patients. However, further research with larger patient cohorts is necessary to establish the effectiveness of SOVTE as a standard therapy option in this population.
