Laryngeal motility alteration: A missing link between XXXX and vagus nerve stimulation for @entity302 .

@entity1 @entity27 @entity302 @entity387
UNASSIGNED: This study aimed to evaluate the prevalence and the relationship of @entity387 ( @entity387 ) and laryngeal motility alterations in @entity1 with @entity302 after vagus nerve stimulator (VNS) implantation. Twenty-three consecutive @entity1 with medically @entity302 underwent out-of-center sleep testing before and after VNS implantation. Eighteen eligible subjects underwent endoscopic laryngeal examination post-VNS implantation. Statistical analysis was carried out to assess an association between laryngeal motility alterations and the onset/worsening of @entity387 . After VNS implantation, 11 @entity1 showed a new-onset mild/moderate SBD. Half of the @entity1 already affected by @entity27 ( @entity27 ) showed worsening of SBD. All of the @entity1 with a new-onset @entity27 had a laryngeal pattern with left vocal cord adduction (LVCA) during VNS stimulation. The association between VNS-induced LVCA and SBD was statistically significant. This study suggests an association between VNS and SBD, hinting to a pivotal role of laryngeal motility alterations. The relationship between SBD and VNS-induced LVCA supports the need to routinely investigate sleep respiratory and laryngeal motility patterns before and after VNS implantation.
