Abstract

Background: Intraoperative neuromonitoring (IONM) of the recurrent laryngeal nerve (RLN) aims to detect and prevent iatrogenic damage during thyroid surgery. Mechanisms of injury include traction, heat damage, and nerve transection. Continuous IONM (C-IONM) techniques detect impending damage due to traction and heat related when they are still reversible.

Methods: We present a 73-year-old woman who underwent a total thyroidectomy due to a goiter. The IONM included intermittent IONM (I-IONM) in combination with C-IONM using the laryngeal adductor reflex (LAR). The intraoperative neurophysiological signals recorded were correlated with the surgical maneuver and the postoperative evaluation.

Results: During surgery, a significant decrease in left LAR amplitude was observed, coinciding with the use of the harmonic. After some corrective maneuvers, the intraoperative signals recovered, and the postoperative examination showed adequate VF function.

Conclusions: C-IONM of the RLN using the LAR can be a valuable tool for detecting and preventing thermal spread injury during thyroid surgery.

期刊介绍： Head & Neck is an international multidisciplinary publication of original contributions concerning the diagnosis and management of diseases of the head and neck. This area involves the overlapping interests and expertise of several surgical and medical specialties, including general surgery, neurosurgery, otolaryngology, plastic surgery, oral surgery, dermatology, ophthalmology, pathology, radiotherapy, medical oncology, and the corresponding basic sciences.
