Adequate treatment of Cleft palate is of great importance for those who suffer from such malformations. Their relationship toward their environment is affected by several aspects : speech, audition, mimic disorders, aesthetical appearance. The treatment is the duty of a multidisciplinary team working together in close collaboration. Hearing impairment is very frequent by CP children due to tube dysfunction in relation to the velum malformation. Considering the pathophysiological conditions, it is now generally recommended to correct every kind of anatomical malformation as soon as possible : early surgery allows the child to develop and acquire a normal phonological system at normal age. It permits an early functioning of velopharyngeal closure with better tube function and an early developement of the speech articulatory system.
