The simplest method is to first incise the upper part of the auricle along the edge of the ear cartilage, open the cartilage to the root of the auricular cartilage, and then apply a free skin graft to the wound behind the auricle and the lateral wall of the skull. Transplant coverage. Since the skin graft is easy to shrink after surgery and affects the surgical effect, the local skin flap transfer method or the local skin flap plus skin grafting method is currently used.

1. Use the method of local flap transfer and use the "V-Y" method of advancing the flap to design a triangular flap with the upper part of the auricle as the base; lift up the triangular flap and peel it open The adhesion surface of the auricle is then folded downward and rearward on the formed wound. The wound in the donor flap area is directly pulled together and sutured after the two sides are subtly separated.

2. Local flap plus skin grafting method

For patients with severe cryptotia or low hairline above the ear, when only local flap transfer cannot cover the entire wound, then This method can be applied.

Characteristics after cryptotia plastic surgery:

1. There is no post-auricular groove due to this disease, which brings great inconvenience to the patient. In addition to being unable to wear glasses, water leaks when bathing. Easy to flow into the external auditory canal. Therefore, surgery can not only improve appearance but also resolve functional impairments.

2. The surgical method is to dissect out the upper part of the auricle cartilage hidden in the temporal scalp and establish a stable posterior auricle groove. The specific method can be divided into skin grafting and local flap method.

3. Routinely apply antibiotics for 3-5 days. Sutures should be removed about a week after the flap method and 12 days after the skin flap and skin grafting method. There should be no external force in the short term after the operation. impact.
