Key Points

This review aims to evaluate the impact of vagus nerve stimulation on upper airway dynamics in obstructive sleep apnea patients.
Retrospective review of drug-induced sleep endoscopy
Assessment of airway dynamics with VNS ON and OFF conditions
Comparison of airway obstruction levels between baseline and stimulation states.
VNS ON shows partial obstruction with anterior-posterior collapse at baseline; airway opening by 1-2 mm observed during stimulation.
VNS OFF indicates no significant movement in airway dynamics; collapsed at the genu but later open laterally.
Overall, VNS appears to modify airway dynamics positively, leading to better airflow.
