Two Cases of Paradoxical Vocal Fold Movement / 대한이비인후과학회지

ABSTRACT

Paradoxical vocal fold movement (PVFM) is a rare disease characterized by the adduction of vocal folds during inspiration. Since patients with PVFM may suffer from acute airway distress or inappropriate treatment for a long period of time, proper diagnosis by the otolaryngologist is critical to proper management. Case 1 was treated with voice therapy which involved self-awarness about what was happening inside his larynx during inspiration, the use of diaphragmatic breathing and laryngeal muscle tension reduction. Case 2 could not be treated with the initial voice therapy but the botulium toxin injection which was used as the second treatment option proved be successful.
