Simple external ear malformation can be repaired by plastic surgery, but for patients with external ear malformation, it is necessary to check the hearing of the inner ear first, which is more critical for the hearing reconstruction and repair of the inner ear structure. It is suggested to go to the hospital for middle ear CT+ inner ear magnetic vibration+otoacoustic emission+auditory brainstem evoked potential examination. If there is indeed hearing abnormality of inner ear malformation, then it is necessary to carry out hearing reconstruction surgery at the same time as external ear plastic surgery. The timing of ear reconstruction surgery is very important. 9 years old, 10 years old, 1 1 year old are the best ages for ear reconstruction. External ear reconstruction surgery is best completed before puberty, because the psychological changes of adolescent children are great, and the impact on children's psychological development before puberty will be much smaller.
