Abstract
Objective:To explore the application value of ultrasound in etiologic judgement of hoarseness after thyroidecomy. Method:Sixty-three cases of hoarseness after thyroidecomy were examed by laryngeal ultrasonography. Vocal cord, arytenoid cartilage, pyriform fossa, thyroid operation area and recurrent laryngeal nerve pathway were evaluated. Regard electronic laryngoscope results as gold standard and compare the differences between the two methods. Result:Sixty-three patients were detected by ultrasound, then, 29 cases were diagnosed with left vocal cord paralysis, 24 cases with right vocal cord paralysis, 2 cases with bilateral vocal cord paralysis, 1 case with right vocal cord polyp, 3 cases with left vocal cord polyp, 1 case with renke layer edema, and 3 cases has normal laryngeal imaging. The accuracy of ultrasonography in determining the etiology of hoarseness after thyroidecomy is 92.1%, the sensitivity is 93.3%, and the specificity is 66.7%. Conclusion:The ultrasonography can not only show laryngeal structures, but also display thyroid operation area and recurrent laryngeal nerve pathway. Moreover, as an non-invasive method, ultrasonography has high accuracy in etiologic judgement of hoarseness after thyroidecomy and certain clinical application values.
