Mannitol Provocation Enhances ILO Diagnosis via Laryngoscopy

Mannitol provocation improves the laryngoscopic diagnosis of inducible laryngeal obstruction (ILO) by accentuating paradoxical vocal fold movement (PVFM). Among 80 suspected ILO patients, PVFM increased from 52.5% at baseline to 72.5% post-mannitol. Accentuation occurred in 56% of cases but was absent in healthy volunteers. Isolated expiratory PVFM without accentuation was not linked to airway obstruction or bronchial hyperresponsiveness.
