WHAT IS A CLEFT?
Early in pregnancy at about 6-8 weeks, the usual fusing,or joining up of tissues of the lip and/or palate does not occur, leaving an opening or “cleft”. A cleft sometimes occurs in the lip, or the palate (soft and/or hard palate), or the lip and palate together. It can occur on one side of the lip/palate (called a uni-lateral cleft) or on both sides (called a bi-lateral cleft). A cleft lip may sometimes be called a ‘hare lip’. This term dates back to medieval times when it was believed a mother gave birth to a baby with a cleft lip because a hare had jumped across her path. ‘Cleft lip’ is a more meaningful term to describe the condition today.
