A case of right non-recurrent laryngeal nerve and related diagnosis and treatment
Non-recurrent laryngeal nerve is a rare anatomical variation.It is divided from the vagus nerve,extends directly to the medial side of the neck after around the carotid artery,and further entering the larynx.The level at which it separates from the vagus nerve determines the path into the larynx.Due to its variable route,there is a high risk of injury during thyroid surgery.In this paper,a case of non-recurrent laryngeal nerve was retrospectively analyzed,and the relevant literature was reviewed.From the preoperative examination,intraoperative operation and other diagnosis and treatment links,the clinical evaluation method of nerve variation is discussed by analyzing the anatomical basis and type of nerve variation,which is helpful to strengthen the intraoperative protection of variant nerves and reduce the probability of injury,so as to improve the quality of life of postoperative patients and reduce the clinical medical risk.
