Abstract
PURPOSE: This study evaluated the efficiency of transcutaneous laryngeal ultrasonography (TLUS) as an alternative to direct flexible laryngoscopy (DFL) in the early postoperative screening of vocal cord palsy (VCP) after total thyroidectomy, performed for benign and non-extensive malignant disease. METHODS: A prospective study was performed on patients who underwent total thyroidectomy between October 2013 and January 2015 at the Nantes University Hospital (France). Patients underwent DFL on postoperative day 1 performed by an otolaryngologist, followed by TLUS performed by a radiologist on postoperative day 1 or 2. RESULTS: One hundred and three (103) patients were included in this study, 17.5% were male and 82.5% were female, with a mean age of 51 ± 12 years. Nine patients (9.5%) were diagnosed with postoperative VCP using DFL of these cases 2 were not completely resolved at 3 months postoperatively. Three cases of VCP (33%) were diagnosed using TLUS. TLUS had a sensitivity of 33% and a negative predictive value (NPV) of 95% for the diagnosis of postoperative VCP. Vocal cords (VC) were unassessable in 27.2% of patients. Unassessable VC were significantly associated with male gender (p = 0.0001), age (p = 0.0001), weight (p = 0.002), operating time (p = 0.032), postoperative drainage (p = 0.001), and thyroid weight (p = 0.001). Independent risk factors in the multivariate analysis were male gender (p = 0.0001) and age (p = 0.0001). In the group of women under 50-year old, TLUS had a sensitivity of 50% and a NPV of 97.4%. CONCLUSION: TLUS sensitivity is insufficient in early postoperative screening of VCP after thyroid surgery. Ultrasonographic VCP diagnosis should be confirmed with DFL.
