目的:探讨耳廓Ⅰ期再造的临床效果及操作要点。方法:采用软组织扩张术获得耳区薄而面积较大的无毛发皮肤,用自体肋软骨雕刻成形,Ⅰ期完成耳廓再造。结果:本组治疗21例,19例效果良好,1例扩张期血肿取出扩张器终止手术,1例再造耳廓部分坏死,经修复后效果满意。结论:扩张法耳再造利用耳区皮肤,经扩张使无发区皮肤表面积增加,皮肤变薄,为再造耳提供了薄而无毛发的皮肤,又由于此法在扩张后一次成形耳廓,在软骨的雕刻上提供了耳立体成形的条件,增加了耳廓立体逼真的效果。
Objective: To investigate the clinical effect and operation points of ear s stage Ⅰ reconstruction. Methods: Soft tissue expansions were used to obtain the thin, larger area of hairless skin in the ear area. The carotid body was carved with autologous costal cartilage, and the auricle reconstruction was completed in stage Ⅰ. Results: In this group, 21 cases were treated, 19 cases achieved good results. One case of dilatation hematoma was taken out of dilator to terminate the operation. One case of rehabilitated auricle was partially necrotic, and the effect was satisfactory after the repair. CONCLUSIONS: The expanded ear reuses and utilizes the ear skin, which expands to increase the surface area of the non-hair area skin and thin the skin, thus providing a thin, hairless skin for the reconstruction ear. Since this method once forms the pinna, The carving of the cartilage provides the conditions for the formation of otoplasty and increases the stereo-realistic effect of the pinna.
