Cleft lip surgery is a surgical procedure performed to treat cleft lip. Cleft lip is a congenital abnormality that occurs in infants characterized by the presence of a gap in the lips and palate. The gap is formed due to imperfect union between the two sides of the lips and the palate. Cleft lip surgery can generally be done on infants aged 3-12 months. If the cleft lip that occurs affects the shape of the nose, the doctor who performs the cleft lip surgery will also improve the patient's nose shape. This nose shape repair surgery is known as rhinoplasty. For the purpose of surgery, the doctor can take tissue from other body parts (grafts). Patients with cleft lip can undergo several operations to completely close the cleft. Indications for Cleft Lip Surgery Cleft lip surgery is performed on a child if he has a cleft lip, cleft palate, or a combination of the two. Cleft lip and palate are often known by doctors after the birth of the baby at the time of postpartum examination.
