Abstract:
Objective To investigate the characteristics of voice changes by multi-dimensional acoustic analysis in patients who underwent thyroid gland lobectomy without laryngeal nerve injury.Methods To observe vocal cord movement and evaluate voice quality,32 patients with unilateral thyroid adenoma received the examinations of fiberlaryngscopy and Multi-Dimensional Voice Program before and after operation,respectively.Forty subjects with normal voice were used as cantrol group.Results Fiberlaryngscopy examinations were normal in all patients before and after surgery.In thyroid group,the preoperative acoustic parameters in male patients showed no significant difference(P＞0.05) compared with the control group.There was no significant difference between preoperative and postoperative acoustic parameters(P＞0.05).While the postoperative acoustic parameters of female patients was significantly lower than those of preoperative and in control group(P＜0.05).There was significant improvement 3 months after the operation compared with that of preoperative group(P＜0.05).Fhi of 3 months after operation was still lower than those of preoperation and in control group in male and female patients that continues to be significant after 3 months.Conclusion Voice changes may occur after unilateral thyroid gland lobectomy without any laryngeal nerve injury,and there is little voice change in male patients,while in female patients,voice improvement is observed after operation.Fhi still remaines lower level for a certain of time.
