    Abstract:
    PURPOSE: There are many reports of the efficacy of laryngeal reinnervation on voice, but there is a paucity of literature regarding its impact on swallowing function. The goal of this study was to explore the impact of laryngeal reinnervation on swallowing outcomes among unilateral vocal fold paralysis (UVFP) patients. METHODS: We reviewed 22 UVFP cases treated with laryngeal reinnervation at our institution. Ten patients had complete datasets, including Eating Assessment Tool (EAT-10) scores and appropriate follow-up. Wilcoxon signed-rank test was used to compare pre- and postoperative scores. RESULTS: Over the study period, 10 cases (mean age 45.7 ± 13.3 years; 6/10 men) with UVFP underwent ansa cervicalis to recurrent laryngeal nerve anastomosis (6/10) or nerve-muscle pedicle procedure (4/10). The median time between injury and surgical reinnervation was 12.4 months (range 2.7-88.5 months). Based on EAT-10 scores 6/10 patients were found to have dysphagia. Of these, four improved their score after surgery, one remained stable, and one deteriorated. The median EAT-10 score of these patients improved from 13 to 7 after surgery, but this difference was not statistically significant (P = 0.138). CONCLUSION: Laryngeal reinnervation procedure has the potential for restoring a near normal voice in UVFP. Laryngeal reinnervation of the vocal fold may be associated with a tendency toward improvement in the EAT-10 score in patients after surgery for hoarseness in the setting of UVFP.
