Various auricular reconstructions including the congenital anomaly such as microtia and the acquired defect and otoplasty are managed.


As a treatment, it is necessary to perform an operation more than 2 times ideally around 10 year-old. Finally, it becomes almost natural-looking ear in appearance.
The costal cartilages taken from the patient's breast are changed into the shape of the auricle and grafted. Because the skin is not sufficient to cover the costal cartilages in shape of the ear, we have to consider the skin coverage method, We select it among two operation methods.1) Expander method: we perform the skin expansion before the cartilage graft, which is excellent in the color match and also maintain the sensibility. 2) Modified Nagata method: we perform the cartilage graft first, after more than 3 months ear elevation with skin graft is performed.
