Velopharyngeal Closure In a nutshell… During normal speech production, the velum moves upward and backward to contact the posterior pharyngeal wall. Simultaneously, the lateral pharyngeal walls move medially to abut against the edges of the velum.* These movements (vp closure)separate the oral and nasal cavities for oral consonants. *The contribution of these components vary among individuals.

Delivery of Care “…children with special health care needs (Koop, 1987)…require comprehensive, coordinated care provided by health care systems that are readily accessible and responsive to the individual needs of the parents and their families.” (ACPA, Parameters of Care, 2007)
ACPA, Parameters of Care (1993, 2000, 2007) Optimal care of children with clefts and craniofacial conditions: Best provided by an interdisciplinary team of specialists From neonatal period through adulthood - until all management needs are met
Team Composition Audiology Dentistry Genetics Oral maxillofacial surgery Plastic surgery Psychology Speech-language pathology Patient and caregivers
Team Responsibilities Recognize the needs of each patient and assist in providing all services needed to complete care Evaluate patients at regular intervals Hold regularly scheduled meetings to discuss findings Develop treatment plan based on patient needs Maintain comprehensive records for each discipline Communicate findings & recommendations Collaborate with providers in the community

Summary Cleft and other conditions affecting VP function can present complex problems Careful evaluations are essential to making an appropriate diagnosis and planning effective treatment Interdisciplinary team management is the standard of care for these patients
