[Effectiveness of modified method for cup ear deformity].

OBJECTIVE

To introduce a modified method to correct type I and type II cup ear and to evaluate the effectiveness.

METHODS

Between May 2006 and November 2011, 23 patients with type I or type II cup ear (27 ears, type I in 6 ears and type II in 21 ears according to Tanzer's criteria) were treated. There were 14 males and 9 females with an average age of 10 years (range, 7-16 years). The unilateral ear was involved in 19 cases and bilateral ears in 4 cases. The main clinical manifestations included the flat helix and scapha and ptosis of upper 1/3 auricle. The arc incision was adopted in the auriculocephalic angle, elevation of the dis-clothing-like flap in the front and rear of the auricular cartilage, relocation of the craniofacial initiation site of the scapha and the cavity of auricular concha, correction of deformational auricular cartilage and reconstruction of smooth helix, antihelix, superior and inferior antihelix crus.

RESULTS

All the incisions healed by first intention without any hematoma, postoperative infection, or flap necrosis. All patients were followed up 9 months-6 years (median, 36 months). No auricle ptosis, deformity contour, or atrophy was observed. The structure of the helix, scapha, and antihelix were clear, natural, and excellent. The scars at the local site were limited and unconspicuous.

CONCLUSION

Modified method can almost correct all the anatomic defects of cup ear. It is an ideal method to treat type I and type II cup ear.
