이개연골성형과 유양돌기 피판을 이용한 매몰귀의 교정

Abstract

Cryptotia is a rare congenital anomaly among Caucasian but more common auricular malformation in Asia. Cryptotia characterized by the anterosuperior portion of the auricle lying beneath mastoid skin. From May of 2005 to May of 2010, three cryptotia were operated on. We use mastoid fasciocutaneous flap (MFF) raised from mastoid region and post-auricular area. And two triangular flaps (TF) which are raised from temporal region can release tension of skin and cover defect of skin. Note that two-thirds of the skin paddle should be taken from the mastoid region. After ear release, MFF and two TF are rotated into the defect. For appropriate correction of the cartilage deformity, the conchal cartilage should be pulled cephalad and fixed to the temporal periosteum. All the patients had a satisfaction for operation. There was no case of partial or full through skin necrosis. There was no wound dehiscence and relapse. The mastoid fasciocutaneous flap is a simple technique, retaining the depth of the auriculocephalic sulcus. This technique can correct deformity of cartilage at same time. There was no distorting hair line, skin color dismatching, visible scar and wound dehiscence.
