Congenital cleft lip is a common congenital malformation of the maxillofacial region, commonly known as “hare lip”. Cleft lip not only causes significant damage to the child’s appearance, but also leads to difficulty in sucking and diction due to loss of the circumferential contraction of the mouth and lip, as well as dental and jaw deformities and secondary nasal deformities caused by abnormal development of the upper alveolar ridge. Currently, treatment for cleft lip and palate has become more procedural and specialized treatment centers have been formed, and treatment outcomes are improving. The treatment of cleft lip requires multiple surgeries for repair. Generally, a simple cleft lip requires a one-stage repair at 3 to 6 months of age. After a cleft lip is repaired, the child will still have certain defects that produce secondary deformities as he or she continues to develop. The nasolabial deformity of cleft lip is often repaired in adulthood, mainly for the aesthetic repair of the nose and upper lip shape. The methods used include prosthetic implants, cartilage implants, and tissue rearrangement. Although the improvement in results after surgery can be very noticeable, the scar cannot be completely removed.
