OBJECTIVE: The nonrecurrent inferior laryngeal nerve (NRILN) is a nerve anomaly that is associated with the developmentally aberrant subclavian artery. Thus, it is possible to predict NRILN by preoperative diagnosis of an aberrant subclavian artery. The purpose of this study was to report a new case of this anomaly and to assess the possibility of diagnosis of an aberrant subclavian artery preoperatively by CT scan of the neck, underline how such recognition is crucial for the prevention of intraoperative nerve damage and review the literature.
METHODS: We report a case of thyroid surgery associated with a right NRILN diagnosed preoperatively by CT scan of the neck.
RESULTS: The preoperative CT scan showed a retroesophageal aberrant right subclavian artery. The patient underwent total thyroidectomy for a multinodular goiter. She had identification of recurrent laryngeal nerve on the left side and NRILN on the right side. Postoperatively, the patient had normal vocal cord function on laryngoscopy.
CONCLUSION: It was possible to predict preoperatively a right NRILN by identifying an aberrant right subclavian artery on the CT film of the neck, which likely enabled the prevention of vocal cord paralysis.
