The cleft lip, also known as harelip, is one of the most common defects of the face and skull. A cleft lip is an incomplete joining of the upper lip, typically occurring just below the nose. A cleft palate is an abnormal passageway running through the roof of the mouth into the nose's airway. Both of these conditions can be corrected through surgery.

Clefts usually form during the fourth to eighth week of pregnancy, often before the woman even knows she is pregnant. After the cleft forms, nothing the mother does or does not do will have an effect on the cleft.

A folic acid deficiency may cause clefts to develop, along with other neural tube defects such as spina bifida. Some medications interfere with the body's absorption of folic acid or other processes that are required for normal fetal development.

One child in 700 is born with a cleft-related birth defect.
