Objective To make an inquiry into how to reconstruct a lifelike ear, and which is one of the most thorny problem in plastic surgery. Methods The operation was divided into two stages: the first stage was that an expander was put into a patient's opisthotic subscutaneous region and lobe of the ear was transposed or laid aside; the second stage was that the expander was taken off by a 2.5～3.0 ㎝ incision at the top or bottom of the expanded flap. The reniform incision except the preauriclar pedical part which was 0.5～0.6 ㎝ away from the expander edge was slit until the deep fascia and dissected forword at the same layer in order to form a "bag-shape" flap. Then, an auricle model was put and fixed and aspirating tube was inserted in the "bag". The back of the reconstructive ear was repaired with the full thickness graft. Results It made operating procedure simple, negative pressure plasty looked good, the blood circuit of flap was increased and occurrence rate of complication reduced. The operation had been performed on 18 patients with a satisfactory results. Conclusion The success rate of the procedure is higher and the shape of the reconstructed ear is more lifelike than that of the traditional one.
