Cleft lip and palate in Madagascar 1998-2007.

Our aim was to find out the prevalence of oral clefts in Madagascar, to compare it with elsewhere in the world, and to give the possible cause of the particular rate in the Vakinankaratra region where Antsirabe is situated. Data were collected from birth registers from 1998 to 2007 in the 10 most important hospitals of the 6 former provinces and of Antsirabe. A total of 150,973 consecutive live births were recorded in the 6 provinces, and 175,981 including those from Antsirabe.
