Auricular reconstruction is one of the most challenging procedures in the field of plastic surgery. The aims of this study were to apply the modified 2-stage method to perform auricular reconstruction and to summarize the clinical experience in the past 10 years.
Auricular reconstruction was performed in 243 patients (total 254 ears) of congenital microtia using autologous costal cartilage. The whole procedure is divided into 2 stages. Stage I: the individualized framework fabricated with autologous costal cartilage is inserted into subcutaneous pocket in the mastoid region, and then the earlobe was transposed backward to connect with the lower part of the framework. The second-stage surgery mainly includes the following main contents: ear elevation, fixing the bracket behind the reconstructed ear framework, harvesting the retroauricular fascial flap to cover the bracket, and closing the defect with free skin grafts.
A total of 243 patients (254 ears) of congenital microtia underwent ear reconstruction. The follow-up time ranged from 6 months to 4 years; 220 patients were satisfied with the results. Surgery-related complications such as infection, partial skin graft necrosis, flap necrosis, bad projection of the constructed auricle, and extrusion of cartilage occurred in 24 cases, and hypertrophic scars occurred in 16 patients.
This modified 2-stage method for auricle reconstruction can receive acceptable results and fewer complications; furthermore, it is relatively simple and easy to master. The 10-year experience validates that this modified method is an ideal method in auricular reconstruction.
耳廓再造是整形外科领域最具挑战性的手术之一。本研究的目的是应用改良的两阶段法进行耳廓再造,并总结过去10年的临床经验。
采用自体肋软骨对243例(共254耳)先天性小耳畸形患者进行耳廓再造。整个手术分为两个阶段。第一阶段:将用自体肋软骨制作的个性化支架植入乳突区皮下袋内,然后将耳垂向后移位与支架下部相连。第二阶段手术主要包括以下主要内容:耳部抬高,将支架固定在再造耳支架后方,取耳后筋膜瓣覆盖支架,并用游离皮片封闭缺损。
共有243例(254耳)先天性小耳畸形患者接受了耳部再造。随访时间为6个月至4年;220例患者对结果满意。24例发生了与手术相关的并发症,如感染、部分皮片坏死、皮瓣坏死、再造耳廓突出不良和软骨外露,16例患者出现增生性瘢痕。
这种改良的两阶段耳廓再造方法可获得可接受的效果且并发症较少;此外,该方法相对简单且易于掌握。10年的经验证实,这种改良方法是耳廓再造的理想方法。
