About Cleft

Overview

Cleft Lip and Palate (CLP) is the most common congenital facial deformity in the world. Approximately 1 in 500-600 children are affected. This means that over 500 children are born with Cleft each year in Bolivia. Cleft Lip and Palate is present in every country and in all sections of society.

Cleft deformations can vary considerably. They can occur as a cleft lip either on one side of the face (unilateral) or on both sides of the upper lip (bilateral), as a cleft palate, cleft lip and palate or cleft lip and maxilla. Other types of cranio-facial clefts such as lateral clefts or facial clefts are rarer. The combined deformation of cleft lip and palate account for seventy per cent of the cases.
