초록
The recurrent laryngeal nerve (RLN) is an important structure that requires careful attention to be preserved during thyroidectomy. Because injury of this nerve results in vocal cord paralysis, which can lead to voice change, aspiration and even pneumonia. RLN often has branches which is vulnerable to nerve injury during surgery. RLN branch usually occurs close to the cricothyroid joint, or close to the junction between the nerve and the inferior thyroid artery. However, if the RLN branch is located lower than inferior thyroid artery, the risk of nerve damage could be increased. We report this rare anatomic variation of RLN case with a review of the literature.
Abstract
The recurrent laryngeal nerve (RLN) is an important structure that requires careful attention to be preserved during thyroidectomy. Because injury of this nerve results in vocal cord paralysis, which can lead to voice change, aspiration and even pneumonia. RLN often has branches which is vulnerable to nerve injury during surgery. RLN branch usually occurs close to the cricothyroid joint, or close to the junction between the nerve and the inferior thyroid artery. However, if the RLN branch is located lower than inferior thyroid artery, the risk of nerve damage could be increased. We report this rare anatomic variation of RLN case with a review of the literature.
