Velopharyngeal Inadequacy

Velopharyngeal inadequacy (VPI) is a malfunction of a velopharyngeal mechanism.

The velopharyngeal mechanism is responsible for directing the transmission of sound energy and air pressure in both the oral cavity and the nasal cavity. When this mechanism is impaired in some way, the valve does not fully close, and a condition known as 'velopharyngeal inadequacy' can develop. VPI can either be congenital or acquired later in life.

    Much literary criticism comes from people for whom extreme specialization is a cover for either grave cerebral inadequacy or terminal laziness, the latter being a much cherished aspect of academic freedom.
