Patient's question:
NoDoctor's answer:
1 Cleft lip, commonly known as "harelip," refers to a split in the upper lip and is a type of congenital malformation. Cleft lip is the most common congenital anomaly of the oral and maxillofacial region and is often associated with cleft palate. In a normal fetus, facial formation begins after the fifth week, with gradual fusion of embryonic protrusions. If this development is not normal, malformations such as cleft lip may occur. It is generally treated through postnatal surgical repair.
