Identification of Non-Recurrent Laryngeal Nerve - A Case Report
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 17, Issue 2
Abstract
The recurrent laryngeal nerves is present on both sides of the trachea, and at the point of entrance to the larynx they are located just lateral to the Berry ligament. They have important anatomic variations. Very rarely, the inferior laryngeal nerve exits the vagus nerve in the cervical region and enters the larynx with a short and straight course from its origin. This anomaly is called “non-recurrent laryngeal nerve”. Injury to the recurrent laryngeal nerve is a serious complication in thyroid and parathyroid surgery. Identification and preservation of recurrent laryngeal nerve (Inferior laryngeal nerve) is one of the most important step during Thyroid surgery. Very rarely, Thyroid surgeons may encounter a Non recurrent laryngeal nerve. A preoperative clinical suspicion, in case of an aberrant subclavian artery or situs inversus and a systematic meticulous dissection will help in the identification and preservation of a non recurrent laryngeal nerve In this case report, we present a non-recurrent laryngeal nerve abnormality in a patient who underwent total thyroidectomy for multi-nodular goitre. A non-recurrent laryngeal nerve was identified on the right side during exploration.
