as the inability to completely close the velopharyngeal sphincter that separates the oropharynx and the naso-
pharynx. Despite primary palatoplasty, VPI can be remained and cause the problems of so called “cleft palate speech”. To treat the cleft palate speech, surgery plays an definitive role in combined with the speech therapy.
