Abstract: Objective To investigate and analyze the voice changes in patients with thyroid nodules before and after surgery. Methods A total of 64 patients who underwent thyroidectomy between July 14, 2020, and September 1, 2020, were grouped according to the type of surgery and sex as follows: female patients with total thyroidectomy(group 1,18 cases), female patients with partial thyroidectomy(group 2, 28 cases), male patients with thyroidectomy(Group 3, 6 cases), and male patients with partial thyroidectomy(Group 4, 12 cases). Electronic nasopharyngolaryngoscopy, dynamic laryngoscopy, VHI-10, GRBAS, and voice acoustic analysis were performed preoperatively and on the third day and after 1 month postoperatively. Results The recurrent laryngeal nerve(RLN)was exposed during the surgery. All cases had RLN signals. Regarding VHI-10 and GRBAS, there was no significant difference between the preoperative and postoperative values of groups 3 and 4(P>0.05). The score of Asthenia(A)for group 1 and the scores of Physiology(P), total Hoarseness(G), and Roughness(R)for group 2 preoperatively and on the third day postoperatively were statistically significant(P<0.05). However, there was no statistically significant difference 1 month postoperatively(P>0.05). On the third postoperative day, the shimmer(group 4)increased(P<0.05)and the MPT(group 1, group 4), SPLmax(group 1, group 2, group3, group 4), and DSI(groups 1, 2, and 3)decreased(P<0.05). All the voice indicators returned to or became better than the preoperative levels 1 month postoperatively: the F0(group 4), MPT(group 1), and DSI(group1, group 2)increased(P<0.05), and the jitter(group1, group 4)and shimmer(group 4)decreased(P<0.05). Conclusion The abnormal voice of patients after thyroidectomy may be related to gender, psychological factors, tumor range, and recurrent laryngeal nerve exposure. The abnormal voice in patients without recurrent laryngeal nerve paralysis is reversible.
