Abstract

Objectives

To study the incidence, sequelae, follow up, and recovery rate of vocal fold motion impairment (VFMI) after complex aortic arch reconstruction in neonates.

Study design

Retrospective case control study.

Methods

We retrospectively evaluated 105 neonates who underwent complex aortic arch reconstruction from 2014-2016. We compared patients that did have VFMI compared to a control group of patients with normal vocal fold movement. Descriptive statistics were computed for all demographic and clinical variables by treatment group.

Results

36% of patients were evaluated for VFMI (n=38) by an otolaryngologist. The incidence of VFMI was 22% (n= 23). Females were more likely to have VFMI (p= 0.02). Aspiration was more common in patients with VFMI (p=0.006). The difference in age, weight, incidence of pneumonia, nasogastric tube, gastrostomy, total length of stay, genetic anomaly, and reintubation was not significant between the VFMI group and control group (p> 0.05). Tracheostomy was not performed in any patients with unilateral paralysis. Only 61% of patients followed up in clinic (n=14). 64% of patients showed improvement or resolution (n=9). Average time to improvement was 4.8 months. Average time to complete resolution was 10.5 months.

Conclusions

VFMI after complex aortic arch reconstruction is relatively common. Despite increased aspiration in patients with VFMI, pneumonia did not occur at all in either group. Tracheostomy was not necessary in any patients with a unilateral paralysis. Most patients showed an improvement in the VFMI within 5 months of surgery. Our data support the need for otolaryngology follow-up.
