Definition
Failure of the soft palate to reach the posterior pharyngeal wall to close the opening between the oral and nasal cavities. Incomplete velopharyngeal closure is primarily related to surgeries (adenoidectomy; cleft palate) or an incompetent palatopharyngeal sphincter. It is characterized by hypernasal speech.
