After phase I repair of harelip patients, it is difficult to put the nasal cartilage in a normal position and fix it after separation because it is still extremely imperfectly developed. If the surgery is not done carefully, it may affect the development of cartilage in the future, so only general and simple correction can be done. Therefore, after the development of the child, the second stage of repair should be done more thoroughly and definitively.
Generally, the surgery is needed in adulthood, when the tissue structure of the lip and nose is basically developed, and the deformation and displacement will not occur again after the surgery, and the more ideal results can be achieved. Therefore, it is very suitable to do orthognathic surgery and residual deformity repair after adulthood.
Adult cleft lip repair surgery is mainly to repair the different degrees of lip and nose deformities left after stage I surgery, mainly in cases of too short and too wide mid-lip, asymmetrical lip redness, too tight and too long upper lip, obvious collapse of the nose, and poorly repaired orbicularis oris muscle.
In severe cleft nose, lip and palate patients, the surgery is more difficult, and the general repair is only for the lip and palate, but because the nose, lip and palate are integrated, usually patients suffering from lip and palate will have nasal problems such as nasal distortion, collapse, or even nasal loss, etc. The traditional cleft lip repair only repairs the lip and palate, but ignores the nose, so the results of conventional surgery are not satisfactory. The combined nasolabial and nasal repair method combines the labial and nasal parts, and the postoperative results are excellent.
