A review of literature relating to velopharyngeal dysfunction reveals that there is no consensus regarding the precise definition of the terms "velopharyngeal incompetence," "velopharyngeal inadequacy," or "velopharyngeal insufficiency." Since this represents an obstacle to communication among members of multidisciplinary teams concerned with rehabilitation of velopharyngeal problems, current usage of these terms is reviewed and recommendations for clarification of the nomenclature are provided.
