自体耳甲腔软骨游离移植修复耳廓部分缺损

Clinical study of the autologous concha cartilage transplantation to repair the auricle defect

目的:探讨自体耳甲腔软骨游离移植修复耳廓部分缺损的临床效果。方法:对7例外伤后耳廓软骨部分缺损的患者采用自体耳甲腔软骨游离移植修复,视软骨缺损大小取同侧或者对侧的耳甲腔软骨缝合固定在缺损软骨处再造软骨支架,取耳周皮瓣转移覆盖软骨,修复耳廓部分缺损。结果:7例耳廓部分缺损患者采用同侧或者对侧耳甲腔软骨游离移植修复,再造耳廓形态满意,随访6个月耳廓软骨未见明显吸收,形态稳定。结论:采用自体耳甲腔软骨游离移植修复耳廓部分缺损,可避免取肋软骨,手术简单,局部麻醉下即可完成手术,长期随访软骨未见明显吸收,效果满意。

Objective:To investigate the curative effect of the auricular defect repaired by the autologous concha cartilage.Methods:Seven cases with the auricular defect were repaired using the autologeous concha cartilage which combined with the retroauricular flap or retroauricular fascia with skin graftin.Results:Total 7 patients were followed up for 6 months after the surgery.The shape and size of the repaired ears were similar to the healthy ears.The teansplanted cartilages were not absorbed or deformed.Conclusion:This method is harmless and simple,which has reliable and satisfactory effects on auricle defect.We can operate under local anethesia and avoid cutting the rib cartilage.
