A congenital deformity in which a child is born with a hole in the roof of their mouth. This could be unilateral or bilateral; one hole or two holes. This deformity is usually corrected at birth and throughout childhood/adolesence. This deformity effects a child's psychological well being as well as physical. So... be nice.
I was born with a unilateral cleft lip and palate.. and no I am not retarded.
