ABSTRACT
One of the most feared complications in thyroid surgery is injury to the superior laryngeal nerve or recurrent laryngeal nerve. Neural identification during surgery is insufficient to assess nerve injury. Intraoperative nerve monitoring of the vagal nerve and recurrent laryngeal nerve during thyroid surgery is a new adjunct designed to allow better identification of nerves at risk and therefore reduce complications related to their injury. This new working tool does not substitute adequate surgical technique but merely provides the surgeon with an adjunct to routine visual identification and functional assessment. The use of nerve monitoring requires standardization of the monitoring procedure. Pursuant to this, we will discuss in two related articles the current state of the art standardized technique of nerve monitoring in thyroid surgery. The aim of part 1 is to provide a concise overview of nerve monitoring in thyroid surgery and its effectiveness. This will include a brief review of the surgical anatomy of the recurrent laryngeal nerve and the key landmarks used to identify the nerve during surgery. Part 2 will describe how to perform the standardized nerve monitoring in a step by step fashion during thyroid surgery which will diminish variable results and misleading information associated with a nonstandardized nerve monitoring procedure.
