耳软骨斜向劈开成形术矫治招风耳畸形

Otoplasty of slited cartilage to correct flaring ear

目的 探索耳软骨斜向劈开成形术矫治招风耳的手术方法。方法 自耳后沿对耳轮及其上脚劈开耳软骨，应用Gibson软骨应力释放原理，在前外侧面顺对耳轮及其上脚渐开线方向行软骨膜磨削或软骨磨削，将软骨劈开线外侧软骨放在劈开线内侧软骨后方，然后再以Mustarde褥式缝合法缝合软骨。结果 应用此法治疗招风耳12例14只耳，术后形态良好。结论 耳软骨斜向劈开成形术是一种矫治招风耳的有效方法。

Objective To study a new method of correcting flaring ear. Methods Auricular cartilage was slited from posterior auricula. On Gibson＇s principle of cartilage distortion antero-lateral cartilage membrane was scarified in order of the involute interpolation of anthelix and cartilage membrance was ground. Then the cartilage outside the slited line was put behind the cartilage inside the slited line. Finally, cartilage was operated with Mustarde＇s mattres suture. Results 12 patients with flaring ear （ 14 ears） were corrected with this operating method and appearance of corrected ears were very good after operation. Following up for 6-18 months, no one recurred. Conclusion Otoplasty of slited cartilage is an effective method of correcting flaring ear.
