In general, doctors cut the upper part of the auricle along the edge of the auricle cartilage according to each person's own situation, turn the cartilage to the root of the concha cartilage, and then cover the wounds behind the auricle and the cranial side wall with free skin graft. Because the skin graft is easy to shrink after plastic surgery of the ear with hidden ear, the local flap transfer method or the local flap plus skin graft method is often used at present.

First, if there is inflammation near the plastic site or incision of the hidden ear, those with ear ulcers should undergo surgery after treatment.

Two, there are infections in other parts of the body, or heart, liver, kidney and other important organs and blood, immune system lesions should not be hidden ear plastic surgery.

Third, elderly patients with weak body should carefully carry out plastic surgery for hearing loss, and those with mental disorders refuse to carry out plastic surgery for hearing loss.
