Application of mastoid flap for correction of moderate or severe cup ear

Objective To propose a practical method for moderate-to-server cup-ear correction.Methods Auricular reconstruction was performed in a manner of two-stage approach with mastoid flap and costal cartilage support.In the first stage,the autogenous costal cartilage framework was inserted under the retroauricular mastoid skin flap.The corrected ear was raised in the second operation and wound was closed with grafting skin.Results Satisfaction of appearance was achieved for totally 18 cases except one case of partly necrosis of cartilage.They were followed-up for 3-26 months.Conclusions This integrative two-stage approach of mastoid flap combining three dimensional costal cartilage is safe and effctive for moderate to severe cup-ear correction,which brings about good appearances and symmetry.The complications are in control.
