I know little about these conditions, and you are most definitely
right.
This from Wiki:
Cleft lip (cheiloschisis) and cleft palate (palatoschisis), which can
also occur together as cleft lip and palate, are variations of a type
of clefting congenital deformity caused by abnormal facial development
during gestation. A cleft is a fissure or opening�a gap. It is the
non-fusion of the body's natural structures that form before birth.
Approximately 1 in 700 children born have a cleft lip and/or a cleft
palate. In decades past, the condition was sometimes referred to as
harelip, based on the similarity to the cleft in the lip of a hare,
but that term is now generally considered to be offensive.
This from the Medical Dictionary:
A cleft is a birth defect that occurs when the tissues of the lip
and/or palate of the fetus do not fuse very early in pregnancy. A
cleft lip, sometimes referred to as a harelip, is an opening in the
upper lip that can extend into the base of the nostril. A cleft palate
is an opening in the roof of the mouth.

I used "hair lip" in the same sense as "Hair-line fracture". Not that
it makes much difference as it's wrong anyway!
