velopharyngeal insufficiency
Pronunciation: VEE-lo-fair-in-JEE-al
Inadequate closure of the velopharyngeal port during speech, resulting in hypernasality and nasal air emission.
Full Definition
Velopharyngeal insufficiency (VPI) refers to incomplete closure of the velopharyngeal port—the space between the soft palate and posterior pharyngeal wall—during speech production requiring oral pressure. This anatomical or functional deficit results in unwanted nasal airflow and acoustic coupling between the oral and nasal cavities, causing hypernasality, nasal air emission, and reduced speech intelligibility. VPI may result from structural abnormalities (such as cleft palate), neurological conditions, or adenoidectomy. Speech-language pathologists assess VPI through perceptual analysis, instrumental measures, and collaborate with surgeons for comprehensive management including possible surgical intervention.
Usage
Usage note: Often abbreviated as VPI; may require interdisciplinary team management.
