Patient: At birth, it was found that the mucosa and skin of the right upper lip were not in the same plane, and the mucosa was slightly higher than the skin by about 2 mm, showing a good crest shape, but not splitting. The child had a cleft lip repair under general anesthesia when he was 11 months old, but after the surgery, he felt that there was not much change from before the surgery, and the scar was more ugly than before. Many people said that it was better not to do it, and I felt the same way. My child’s situation is that the lateral incisors and permanent cusps on the right side have not yet erupted and there is a gap between them, but they are not completely cracked. And it is accompanied by collapse of the right side of the nose. The most important thing I want to know now is whether it is necessary for my child to have iliac bone graft? What is the result after transplantation? Ma Lian, Department of Maxillofacial Surgery, Peking University Oral Hospital Ma Lian, Department of Maxillofacial Surgery, Peking University Oral Hospital: If you hope to get an intact treatment result or you should have bone graft, there are many factors affecting the effect of bone graft, if the age is appropriate and the patient goes according to the doctor’s requirements, the success rate is still possible.
