Abstract:
Objective To study the dynamic changes and potential impacts on the voice in postoperative pa-tients with different types of thyroid operation.Methods A total of 48 cases thyroidectomy,34 with thyroid isth-mus and lobectomy and 4 with total thyroidectomy,and 19 cases neck operation were included in this study for the examinations of electric laryngoscope,and acoustic voice analysis preoperative and postoperative,respectively.The characteristics of the acoustic parameters were analyzed.Results Vocal cord paralysis and cricothyroid joint disloca-tion in all the patients before and after operation were not observed.For male patients in the experimental group, postoperative parameter values of F0TD were higher than the day before surgery and 30 days after thyroidectomy. The difference was statistically significant (P <0.05 ).In female patients,postoperative parameter values of F0 were lower than the day before surgery and 2nd,7th,and30th day after thyroidectomy.Postoperative parameter values of Jitter for 30th day were lower than 1st day after the operation.The postoperative parameter values of F0TD for 1st,2nd,3rd,and 7th day were higher than the day before thyroidectomy.The parameter value of F0TD was lower than 1st day after surgery,and the postoperative parameter value of HNR for 30th day was lower than 3rd day after the thyroidectomy.The difference was statistically significant (P <0.05 ).Compared to the control group,there were no significantly differences in male patients of experimental group before and after the surgery(P >0.05).The parameter values of F0 in famale patients before the thyroidectomy,the 1st,2nd,3rd,7th day after the surgery and the parameter value of Jitter,Shimmer,HNR for 1st day after the operation were significantly dif-ferent(P <0.05).There were no significant differences in all parameter value of 30 days after thyoidectomy(P >0. 05).Conclusion Voice parameter values alter in a way after thyroid surgery without apparent recurrent laryngeal nerve injury,especially in the female patients.The improvement of voice acoustic parameters can be observed on the 30th day after operation.
