External ear reconstruction is generally a repair and treatment operation for congenital ear malformation or ear defect caused by external reasons.

Total auricle reconstruction includes the high technical difficulty of plastic surgery, and the difficulty lies in the cutting of skin flap, fascia flap, costal cartilage, carving of cartilage scaffold and skin grafting. A realistic auricle needs to be thin and smart, close to normal ears, and also needs a realistic three-dimensional sense.

Optimum age

External ear reconstruction with costal cartilage should be carried out after the child 10 years old, because costal cartilage needs to be removed from the child's own costal cartilage to carve the ear bracket. If the child's costal cartilage is taken in the child's growth and development stage, it will cause problems such as thoracic deformity of the child. Therefore, many experts think that 10 years old may be too early, because personal development is different and the problem of thoracic deformity is avoided. As far as the effect of ear reconstruction is concerned, some children 10 years old have insufficient bone mass, which will directly affect the effect of the operation.

Optimal operative age

Disposable ear prosthesis is the most advanced external ear reconstruction technology at home and abroad. It is made of American high-tech biomaterial Medpor, and it can be operated when the child is about 5 years old. The disposable ear prosthesis can be operated before the child's preschool age because it does not need to carve the child's own costal cartilage, thus avoiding some psychological obstacles caused by the child being laughed at by other children.
