Intraoperative neuromonitoring of the recurrent laryngeal nerve (RLN) is used to minimize risk of RLN paralysis during thyroid surgeries.
Laryngotracheal anesthesia (LTA) decreases coughing upon emergence, minimizing risk of hematoma formation.
LTA is prohibited during these cases because of concerns that it can interfere with intraoperative neuromonitoring of the RLN.
We show that LTA administration does not have an inhibitory effect on the conduction of the RLN.
