乳突区皮瓣法在先天性中重度杯状耳三维重建中的应用

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

目的 探讨中重度杯状耳三维立体重建的有效方法及临床效果.方法 采用乳突区皮瓣及自体肋软骨切取的Ⅱ期再造方法对中重度杯状耳进行三维重建.Ⅰ期行外耳皮肤脱套、乳突区皮瓣分离;切取肋软骨与耳轮软骨桥接重建耳上极及乳突区皮瓣包盖.Ⅱ期行再造耳上极掀起,耳后筋膜瓣覆盖及植皮重建.结果 18例中重度杯状耳畸形患者,1例桥接处糜烂,软骨部分坏死,其余均Ⅰ期成活,随访3～26个月,外形满意.结论 应用乳突区皮瓣法重建中重度杯状耳,强调细节亚单位构建,再造耳更加安全、美观,手术成功率和医患满意率高,并发症少.

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.
