Abstract：Objective To explore the value of vocal cord function in perioperative period by Ultrasonography,so as to pro-vide imaging reference information for clinical diagnosis and evaluation.Methods 260 patients underwent thyroidectomy were selected.Then,we evaluated the accuracy of vocal cord abnormality detection in different sex,age,body mass index(BMI),na-ture of tumor and operation method before and after operation,and preoperative and postoperative vocal cord abnormality accu-racy,sensitivity,specificity.Results With laryngoscopy results as the gold standard,in 260 patients,the diagnostic accu-racy,sensitivity and specificity of ultrasonography before operation were 92.69%,87.50%and 93.22%,after operation,those were 87.69%,84.91%,88.41%,and the before and after operation,all those were 85.71%,90.19%,90.97%,the results were consistent with those of laryngoscopy(Kappa=0.815,P<0.05).The diagnostic accuracy of males,with age≥50 years old,and BMI≥24 kg/m2 was lower than females,with age<50 years old and BMI<24 kg/m2 before operation and after operation(all P<0.05).Conclusion Percutaneous laryngography can accurately assess the function of vocal cord in the perioperative period of thyroid surgery,which can be used as a screening method for vocal cord paralysis before and after thyroid surgery.
