It is usually difficult to control the development of mandible. If your mandible is genetically overdeveloped, no matter what you do, you can only temporarily stop growing and eventually grow.

If the maxilla is hypoplastic, the doctor will pull it at an appropriate time to promote the growth of the maxilla, usually before the peak of growth and development.

But your situation is more complicated, because you have cleft lip and palate, you may need to expand your arch or bone graft, which involves multi-department combined treatment, and the specific time should be considered comprehensively

Your maxillary dysplasia is mainly caused by cleft lip and palate.

The mandible is not necessarily overdeveloped, and sometimes it may be because the maxilla is too flat, which makes the mandible appear overdeveloped. Just take an X-ray.

At present, it is recommended to consult the orthodontics department of a regular hospital first.
