Background:Postoperative dysphagia, hypocalcemia, hoarseness, shortness of breath, a permanent requirement for replacement therapy, scarring in the surgical site, and other complications are possible after thyroid surgery and may lower the patient's quality of life following the procedure.The present study was conducted to assess voice outcomes in patients after thyroidectomy.Materials & Methods:100 patients were studied.Perceptual assessment was performed using the GRBAS scale, completed by a speech therapist on a sample of spontaneous speech for each study participant. Each of the scale’s parameters, including the Grade of Abnormality (G), Roughness (R), Breathiness (B), Asthenia (A), and Strain (S) were assessed on a four-grade scale (0 – normal voice, 1 – mild deviation, 2 – moderate deviation, and 3 – severe deviation).Results: Out of 100 patients, 54 were males and 46 were females. tumor was Papillary in 62, Follicular/Hürthle cell in 38. Tumor size was <1 cm in 36, 1-2 cm in 14 and 2-4 cm in 50. Extent of disease was localized in 62, regional in 25 and distant in 13. Treatment done was lobectomy in 7, total thyroidectomy in 45, with dissection location unknown in 24 and with central neck dissection in 9 and with lateral neck dissection in 15 cases. The difference was significant (P< 0.05).Before voice therapy and after voice therapy, mean JITT (%) value was 1.02 and 0.58, SHIMM (dB) was 0.67 and 0.29, HNR (dB) was 2 and 3, G was 2 and 1, R was 2 and 1, B was 2 and 0, A was 2 and 0, S was 0 and 0 and VHI-T was 62 and 11 respectively. The difference was significant (P< 0.05).Conclusion: There were improvements in all voice parameters after voice therapy, voice rehabilitation seems to be the essential clinical activity for thyroid surgery patients who suffer from voice disorders postoperatively.
