Cup-shaped ear plastic surgery This method is usually two operations. The costal cartilage was removed in the first operation, and the ear bracket engraved with costal cartilage was directly implanted under the skin behind the ear. This is the most critical second operation. If you do it for the third time, you can repair your ears more beautifully. Each operation takes about 10 days, and the method is simple, safe, short in treatment time and less painful for patients.
