CHILD’S HEALTH/EAR, NOSE AND THROAT DISORDERS: CLEFT LIP AND CLEFT PALATE
These are congenital defects (defects present at birth). During development of the foetus, there is incomplete closure of the lip or the roof of the mouth, forming an open cleft. Each can occur separately, but they often occur together, sometimes in association with other malformations. Usually only soft tissues are affected, but occasionally bone can be involved, causing deformity of the nose as well. Cleft lip alone is more common, occurring in about 1 out of every 1000 births; cleft palate occurs in about 1 out of every 2500 births.
Cause
The exact cause is unknown. Genetic influences are believed to be largely responsible.
Clinical features
The defect varies in severity, from a small notch in the upper lip, to a gaping defect of the lip and palate, and sometimes the nose. Aside from the obvious appearance of the lips and mouth, a baby with cleft lip and/or cleft palate will have significant difficulty with feeding. This is because they find it difficult or impossible to suck, even though they have no problems with swallowing. They are usually otherwise very normal children.
Treatment
Initially the baby is fed with a special spout or elongated teat that delivers milk to the back of the throat. Surgery is always necessary, and the type and extent depends on the degree of deformity. The lip is usually repaired at 2-3 months of age, and the palate at around 1 year, before the baby starts to speak. Occasionally minor corrections are made before the child starts school. The cosmetic results with cleft lip alone are usually excellent. Speech therapy can help enormously in correcting nasal-sounding speech in the case of a cleft palate. Regular follow-up with your doctor is essential, as these children are more prone to develop ear infections and subsequent problems. Specialised dental care may also be necessary.
Prevention
Cleft lip and palate cannot be prevented.
