Cleft lip and palate as seen in the University College Hospital, Ibadan.

The purpose of this study was to update cleft lip and palate anormalies in Nigerian Africans using clinic materials. Hospital available information about records of 45 children with cleft lip and palate were reviewed. The 24 males and 21 females were all seen at the Dental centre, U. C. H., Ibadan during a period of six years. Twice more females than males had complete cleft of the palate and alveolar process on one side of the premaxilla. Majority of the clefts of the soft and hard palates on both sides of the premaxilla occurred in males with a male-to-female ration 6:1. There were several bilateral clefts and a preponderance of left unilateral clefts over clefts on right side. No other clear-cut patterns emerged probably because of small sample size.
