Abstract

Objective

To determine the frequency of aspiration resolution after recurrent laryngeal nerve (RLN) reinnervation among children with dysphagia.

Study Design

Case series with chart review.

Methods

All pediatric RLN reinnervations between January 2013 and December 2022 at a tertiary aerodigestive program were included. Only children completing video fluoroscopic swallow studies (VFSS) prior to the RLN procedure were analyzed. Postoperative outcomes included swallowing function from VFSS, including thin liquid aspiration.

Results

Twenty-four RLN reinnervations were reviewed, with six children obtaining both preoperative and postoperative VFSS. Following RLN reinnervation, no patients were noted to aspirate, and all patients had advancement in their diet consistencies.

Conclusions

Resolution of dysphagia and advancement of the oral diet after RLN reinnervation is common among children with aspiration and unilateral vocal fold immobility. Long-term improvement of swallowing function in children with unilateral vocal cord paralysis corrected by RLN reinnervation must be examined further.
