Vocal fold function research

From: Koufman, J. A., & Block, C. (2008). Differential Diagnosis of Paradoxical Vocal Fold Movement. American Journal of Speech-Language Pathology, 17(4), 327. doi:10.1044/1058-0360(2008/07-0014)

Purpose: To present the differential diagnosis of paradoxical vocal fold movement (PVFM) and its distinguishing features.

Methods: The authors provide an overview of PVFM by drawing from 30 years of clinical and research experience, and relating that experience to literature in this area.

Conclusion: PVFM is characterized by inappropriate adduction of the vocal folds during inspiration. PVFM is an uncommon and some- times confusing cause of airway obstruction. The resultant obstruction may be intermittent or continuous, mild or severe. Most patients with PVFM have a specific etiology— inflammatory, neurological, neoplastic, iatrogenic, or psychological—that influences type of treatment and outcome.
