Effect of Velopharyngeal Gap Size on Laryngeal Morphology and Vocal Function in Children With VPI

Sponsor: Assiut University

Summary

Speech production relies on the precise coordination of the respiratory, phonatory, resonatory, and articulatory systems . The velopharyngeal mechanism is essential in separating the oral and nasal cavities during speech and swallowing. Disruption of this mechanism leads to velopharyngeal insufficiency (VPI), which is characterized by the inability to achieve complete velopharyngeal closure due to structural or anatomical deficits. VPI is frequently associated with cleft palate, either repaired or unrepaired. It may also occur secondary to submucous cleft palate (CP), craniofacial syndromes, short palate, or post-adenoidectomy.
