“…Unlike other studies that also included swallowing complaints within their quoted rates of 10-13%, in this study we only evaluated complaints specific to voice. 9,10 The yield of routine laryngoscopy in our study population is quite low with abnormalities found in only 6% of patients undergoing laryngoscopy, compared with 18-36% found in other studies. 6,11 Our rate of preoperative cord paralysis (2%) is in line with findings in other studies (1-7%).…”

“…However, up to 30% of patients with normal VF mobility after thyroid surgery complain of subjective voice changes of which exact cause remains unclear [17,18] . In such patients with postoperative symptoms, fiberscopic examination should be performed to protect the surgeon from subsequent litigation [19] or not to overlook any other abnormalities in the larynx, even when VF mobility can be observed by US.…”

Background: Evaluating recurrent laryngeal nerve function before and after thyroid surgery is important. Although laryngeal electroendoscope is the most reliable tool for evaluating vocal fold (VF) mobility, ultrasonography (US) may offer a non-invasive alternative. The aim of this study is to evaluate the validity and limitation of US evaluation for the assessment of VF mobility.Methods: This was a study for diagnostic testing of US in a single center. One hundred and one patients who underwent thyroid surgery between February 2011 and August 2011 were enrolled to this study. Observation of the VF mobility using a B-mode US scanner was performed before and after thyroid surgery, through the thyrohyoid membrane, thyroid notch, and cricothyroid membrane. The results of US were compared with those of electroendoscopic examination which was performed on the same day but after the US.Results: First we excluded one case that could not be observed by electroendoscopic examination before surgery. After excluding the cases which the VF mobility was invisible by US, we analyzed 89 out of the 100 patients before thyroid surgery and 89 out of the 101 patients after surgery. The sensitivity and specificity of US were 87.5%, 100% for before and 94.4%, 100% for after surgery, respectively. It was significantly more difficult to assess the VF mobility by US among patients who were men (odds ratio [OR] 24.7, 95% confidence interval [CI] 4.9-124.2), 65 years old or more (OR 3.5, 95% CI 1.0-11.9), and have past history of thyroid surgery (OR 7.9, 95% CI 2.1-29.2). Being obese was also a significant factor (OR 10.5, 95% CI 1.7-64.8) among younger patients (less than 65 years).Conclusion: US evaluation can be used for the assessment of recurrent laryngeal nerve function before and after thyroid surgery. This is a safe and non-invasive diagnostic tool which may be performed as a first-line method.

“…Preoperatively, VCF detects an existing RLN palsy from local invasion of the nerve by extrathyroidal cancer extension or regional lymph node metastases [8,11,12]. Postoperative assessment of VCF document a wellpreserved VCF, or an iatrogenic RLN injury, and yet the benefits of speech, rehabilitation, steroid, and surgical treatment [7].…”
