Abstract
The recurrent laryngeal nerve is at risk of injury during open pharyngeal diverticula operations. The utility of recurrent laryngeal nerve (RLN) monitoring during these procedures was investigated. A retrospective chart review was performed of 8 open pharyngeal diverticulectomies completed between 2009 and 2014. Intraoperative RLN monitoring took place during all operations. Open pharyngectomy and myotomy was successfully performed in all cases. In two cases the RLN was encountered outside of its normal course. The identity of the nerve was confirmed with electrical stimulation and normal EMG response. Vocal fold motion was preserved in all cases. Use of intraoperative nerve monitoring in pharyngeal diverticula procedures may be beneficial, especially during open operations for Killian-Jamieson diverticulum (KJD) and large Zenker diverticulum (ZD), where the RLN is typically encountered outside of its normal course.
