Abstract

Objectives/Hypothesis: Lower cranial nerve injury may be an under-reported complication of vestibular schwannoma surgery. This study aims to characterize the prevalence of complications associated with vagus nerve injury following vestibular schwannoma surgery and the impact of these complications on patient care. Study Design: Retrospective cross-sectional study. Methods: Discharge data from the Nationwide Inpatient Sample for 17,281 patients with vestibular schwannoma who underwent surgery in 2003-2008 were analyzed using cross-tabulations and multivariate regression modeling. Results: Dysphagia was reported in 443 cases (2.6%) and unilateral vocal fold paralysis in 115 cases (0.7%). The mean length of hospitalization was 5.3 days (95% confidence interval [CI], 4.9-5.7) and was prolonged in patients with dysphagia (mean, 11.7 days; 95% CI, 8.9-14.4) and in those with unilateral vocal fold paralysis (mean, 12.1 days; 95% CI, 7.3-16.9). Compared to patients without dysphagia, a diagnosis of dysphagia was associated with advanced comorbidity status (37.0% vs. 18.8%), central nervous system complications (39.3% vs. 15.3%), aspiration pneumonia (7.1% vs. 0.4%), and greater likelihood of requiring medical care at another facility or at home after discharge (48.5% vs. 6.6%, P
