Relationship to cleft palate A cleft palate is one of the most common causes of VPI. Cleft palate is an anatomical abnormality that occurs in utero and is present at birth. This malformation can affect the lip and palate, or the palate only. A cleft palate can affect the mobility of the velopharyngeal valve, thereby resulting in VPI.
