The anatomy and tissue characteristics of the ear render reconstructive procedures addressing local defects on the scapha challenging. Twenty patients with variously caused defects on the scapha underwent a one-stage reconstruction with retroauricular pedicled flaps raised without axial vessels. Flap elevation, followed by incision and tunnelling of the cartilage, enables easy access to the defects at the centre of the external surface of the concha. There were no flap losses, no postoperative wound infection and no asymmetries noted in the follow-up. Retroauricular pedicled flaps with random blood supply are safe and ideal for one-stage closure of defects, no larger than 3.5 cm in size, in the lateral anterior part of the external ear. Good functional and aesthetic outcomes can be achieved.
耳的解剖结构和组织特点使得重建手术来修复舟状骨局部缺陷具有挑战性。20 名患有各种原因导致的舟状骨缺陷的患者接受了经耳后带蒂皮瓣一期重建术，该皮瓣不携带轴型血管。皮瓣掀起后，切开并向软骨隧道，可轻松进入外耳表面中心的缺陷处。在随访中，没有皮瓣丢失、术后伤口感染或不对称的情况。带有随意皮瓣血供的耳后带蒂皮瓣是安全的，适用于一期修复大小不超过 3.5cm 的外耳前外侧缺陷。可获得良好的功能和美学效果。
