Abstract

Background: Voice changes are common complaint following thyroidectomy that might or might not be associated with laryngeal nerve damage. Objective: The aim of this study is to evaluate the effect thyroidectomy on voice alteration and its association with gender and age. Methods: In this descriptive analytical study, patients who underwent thyroidectomy at (XXX) without laryngeal nerve damage were included. These patients were evaluated based on subjective (self-reported) and objective (videostroboscopy) voice assessment. The data was collected immediately after the surgery and 6 months after the surgery during the follow-up. Results: Of 76 patients included, the mean age of patients was 46.3 year. 25 (43.4%) were males and 51 (56.6%) were female. 28.9% patients were presented with apparent damage to the vocal cords, of which 8 (10.5) had voice changes. There was no statistically signifcant difference between sex and postoperative vocal cord dysfunction (P = 0.592). However, in male gender, late postoperative voice changes were signifcantly more, p = 0.013. The age was also not associated with immediate or late postoperative changes and damage to vocal cords, p > 0.05. Conclusion: Our study reported that male gender can be an important factor in deterring voice changes after thyroidectomy nonetheless, it can not predict the risk of vocal cord damage. Furthermore, age might not a risk factor either. Studies with greater sample size are required to confrm these fndings. t a,b, c, a,e,*, Hossein Chitgarchari
