We aimed to evaluate the effect of  strep muscles’ division on voice and swallowing alterations following thyroidectomy. Methods: The study group consisted of 17 patients who had strep muscles’ division during the thyroidectomy and a control group of 17 patients who also had no recurrent and superior laryngeal nerve injuries. Voice impairment scores (VIS) and swallowing impairment scores (SIS) were obtained preoperatively and at 1 week, 1 month, 3 and 6 months postoperatively. Results: The 2 groups were well matched regarding age, sex, thyroid pathological findings and type of operations. The mean VIS of the Groups 1 and 2 preoperatively, at 1 week,1 month, 3 and 6 months postoperatively were  3.3±2.6 vs 2.8±5.3 (p=0.054), 11.1±10.2 vs 6.4±7.8 (p=0.084), 7.1±8 vs 5.2±8 (p=0.159), 6.3±7.8 vs 3.1±4.8 (p=0.072), 4.8±5.7 vs 2.2±3.8 (p=0.101) respectively. The mean SIS of the Groups 1 and 2 preoperatively, at 1 week,1 month, 3 and 6 months postoperatively were 3.5±4.7 vs 3.7±4.4 (p=0.874), 7.2+5.9 vs 5.1+5.3 (p=0.253), 5.9+5.1 vs 3.1±3.9 (p=0.097), 2.1±2.9 vs 2.7±4.2 (p=0.967), 3.8±5.7 vs 2.9±5.4 (p=0.849) respectively. The mean VIS and SIS were significantly higher than the preoperative values at 1 week after thyroidectomy in both of the groups. However the scores became similar to the preoperative values at 1 month after thyroidectomy. Conclusion: Although the voice and swallowing complaints increase in the early postoperative period, these complaints are not related with the division of the strep muscles.
