The tumbling concha-cartilage flap for correction of lop ear.

This article presents a new surgical method that uses tumbling concha-cartilage flaps to correct lop ears. Through a posterior or anterior auricular skin incision, a rectangular or T-shaped cartilage flap is elevated from the concha and tumbled backward. After passing under the postauricular skin, the flap's tip is fixed to the lidded helix or scapha. The recoiling force of the flap's conchal side enables the lidded portion to be in a normal, erect, anatomic position. The method also increases the vertical height of the ear and creates a normally shaped scapha. Sixteen lop ears were corrected using this procedure, with most of them maintaining natural auricular features. Therefore, this method was considered effective for the correction of moderate lop ear deformity.
