cleft palate noun (Concise Encyclopedia)
Fairly common congenital disorder in which a fissure forms in the roof of the mouth. It may affect only the soft palate or extend through the hard palate, so that the nasal cavity opens into the mouth. The septum (dividing wall) between the nostrils is often absent. Cleft lip, a fissure in the lip beneath the nostril, or other abnormalities may accompany it. Cleft palate limits the ability of an infant to suck, which may lead to malnutrition, and causes speech problems in childhood. Surgical repair, usually at about 18 months of age, forms an airtight separation between nose and mouth. Speech training is still needed, and patients may have a high risk of nose, ear, and sinus infections.
