Matters needing attention in cup-shaped ear plastic surgery should first determine what kind of cup-shaped ear the patient belongs to, such as the auricle leaning forward or the auricle curling, and then decide the plastic surgery method. Friends with serious cup-shaped ears will be affected by wearing glasses, so plastic surgery of cup-shaped ears is very necessary. Cup-shaped ear, also known as rolled ear or drooping ear, is a congenital malformation between windy ear and small ear, accounting for about 10% of all kinds of congenital ear malformations. It is common on both sides, but it is not necessarily symmetrical on the left and right, and it has certain heredity. Ear curl is only the fold of the helix itself, while the upper part of the ear hangs down and covers the ear hole. The auricle leans forward, but it is different from simple ear deformity; Ears become smaller, mainly because the length of ears becomes shorter; The position of auricle is low, which is more obvious in severe cases, and is often accompanied by maxillofacial deformity. For severe cup-shaped ear deformity, posterior auricular flap and cartilage transplantation are needed to repair it. Methods A full-thickness incision was made in the upper part of auricle to correct the deficiency of helix. At the same time, a small piece of cartilage was taken from the external ear and added to the defect of the helix margin to form a stent, and then a local flap was formed behind the ear to cover the wound, and the donor site was free.
