Background: Voice and swallowing symptoms following thyroidectomy are frequently reported even without laryngeal nerves’ injury. 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.
