Velopharyngeal insufficiency.

Willging JP.

Department of Otolaryngology-Head and Neck Surgery, Children's Hospital Medical Center, Cincinnati, OH 45229-3039, USA.

Velopharyngeal insufficiency (VPI) refers to the mobility of the velopharyngeal sphincter to adequately separate the nasal cavity from the oral cavity during speech. The auditory result of this structural problem is hyperrhinophy, abnormal resonance and the production of distracting noises during speech created by turbulent airflow escaping from the nasal cavity.
