Non-recurrent laryngeal nerve injury associated with an aberrant right subclavian artery: a case report.

Background: Injury to the recurrent laryngeal nerve (RLN) is a recognised complication of surgery in the neck. The presence of a non-recurrent laryngeal nerve (NRLN) significantly increases the risks of a nerve injury. Given that NRLNs are strongly associated with vascular abnormalities that can be visualised on preoperative imaging, we describe a case to raise awareness of this association with the aim of reducing the risk of iatrogenic nerve injury.
