Because auricular reconstruction is a complex and relatively uncommon procedure, there are many patients that have had disappointing reconstructions. This study describes the authors' large experience with secondary procedures in patients with unsatisfactory or failed initial ear reconstruction.
A prospectively maintained database of all consecutive patients who underwent secondary total ear reconstruction from March of 1991 to December of 2017 was reviewed. Demographic data and outcomes were assessed. Patients with acquired absence of the ear were not included.
There were 144 microtia patients that met the inclusion criteria. Patient age at the time of the secondary reconstruction ranged from 3 to 59 years. Follow-up duration ranged from 1 to 21 years. Primary reconstruction was performed with rib cartilage in 91 patients, porous polyethylene implant in 47 patients, prosthesis in four patients, and irradiated cadaver rib cartilage in two patients. All secondary reconstructions were performed with porous polyethylene implants. The alloplastic framework was covered with a temporoparietal fascia flap in 76 patients, an occipital fascia flap in 64 patients, and a free fascia flap in four patients (two radial forearm flaps in the same patient, one contralateral temporoparietal fascia flap, and one lateral arm flap). Fourteen patients (10 percent) had complications requiring revision surgery. Secondary surgery was successful in all but one patient.
These data represent the largest series of secondary total ear reconstructions. The use of a porous polyethylene implant is an ideal method for these patients because of its minimal morbidity and relatively low complication rate.

由于耳廓重建是一项复杂且相对少见的手术,因此有许多患者的重建效果并不理想。本研究描述了作者在对初次耳廓重建不满意或失败的患者进行二次手术方面的丰富经验。
回顾性分析了 1991 年 3 月至 2017 年 12 月间所有连续接受二次全耳重建的患者的前瞻性维护数据库。评估了人口统计学数据和结果。未纳入因后天原因导致耳部缺失的患者。
符合纳入标准的有 144 名小耳畸形患者。二次重建时患者的年龄为 3 至 59 岁。随访时间为 1 至 21 年。91 例患者采用肋软骨进行初次重建,47 例患者采用多孔聚乙烯植入物,4 例患者采用假体,2 例患者采用辐照尸体肋软骨。所有二次重建均采用多孔聚乙烯植入物。76 例患者采用颞顶筋膜瓣,64 例患者采用枕筋膜瓣,4 例患者采用游离筋膜瓣(同一患者 2 例为桡侧前臂皮瓣,1 例对侧颞顶筋膜瓣,1 例侧臂皮瓣)覆盖。14 例(10%)患者需要进行修复手术。除 1 例患者外,其余患者二次手术均成功。
这些数据代表了最大的二次全耳重建系列。由于多孔聚乙烯植入物的发病率低,并发症发生率相对较低,因此是这些患者的理想方法。
