The study aimed to identify the electrical characteristics of nonrecurrent inferior laryngeal nerves (NRILNs) during thyroid surgeries using intraoperative neuromonitoring (IONM) and look for associated vascular anomalies.
Out of 7865 thyroidectomy patients, 42 had NRILNs, with most cases detected through specific EMG signs and difficulties identifying the recurrent laryngeal nerve.
The findings showed a 0.53% prevalence of NRILNs, with a significant percentage having vascular anomalies, and suggest early detection methods during surgery to reduce the risk of nerve injury.
