Background
Laryngeal complications occur in thyroidectomies as a result of several factors, but especially because of nerve damage. We compared intraoperative stimulation neuromonitoring (IONM) with intraoperative continuous electromyographic neuromonitoring (IEM) to evaluate their ability to identify postoperative laryngeal complications.Methods
This prospective clinical trial included 174 patients (348 nerves) who had both IONM and IEM. We recorded age, sex, pathology, vocal fold motility, and complications.
Results
IONM identified 334 nerves, whereas IEM identified 348. Five patients had transient laryngeal complications, 2 bilateral, and 3 unilateral recurrent laryngeal nerve paresis. In addition, in 2 patients IEM showed placement of the tracheal tube balloon on the vocal folds, which led to correction. Sensitivity and specificity were 96.48%and 100%for IONM and 100%and 100%for IEM, respectively. IONM had a positive predictive value of 100%and a negative predictive value of 36.84%. The positive and negative predictive values of IEM were 100%.
Conclusions
Both techniques identify recurrent laryngeal nerve injuries; however, IEM seems to have an advantage concerning the nonsurgical laryngeal complications and may play a role in preventing morbidity.
