During conventional reconstruction of the auricle in patients with microtia, simply separating the auricle from the mastoid region with a full-thickness skin graft usually fails to create firm elevation and sufficient projection. To achieve frontal symmetry is difficult, and sometimes the normal auricle needs to be set back. We reconstructed the auricle in patients with microtia in two major stages using a modified Nagata's method. Using a wide W-incision skin flap, the first stage includes implantation of a cartilage framework and transposition of the ear lobule. Our modification lies in the second stage. Instead of using the superficial temporoparietal fascial flap, we elevated a retroauricular fascial flap from the mastoid region, turning it over to wrap an autogenous costal-cartilage wedge, and covered it with a full-thickness skin graft. Between June 1996 and May 1999, eight patients underwent this operation. All the fascial flaps and overlying full-thickness skin grafts survived well. The advantages of our technique include firm elevation, good frontal projection and a natural appearance of the posterior aspect of the ear. Additionally, by using this fast and practical procedure, we avoid creating additional scars on the scalp and preserve the superficial temporoparietal fascia and superficial temporal vessels.
在小耳畸形患者进行传统耳廓再造时,单纯采用全厚皮片将耳廓与乳突区分离,通常难以实现稳固的抬高和足够的突出。要实现正面对称较为困难,有时还需要将正常耳廓后移。我们采用改良的永田法分两个主要阶段对小耳畸形患者进行耳廓再造。第一阶段采用宽W形切口皮瓣,包括植入软骨支架和耳垂移位。我们的改良之处在于第二阶段。我们不是采用颞浅顶筋膜瓣,而是从乳突区掀起耳后筋膜瓣,将其翻转以包裹自体肋软骨楔,并覆盖全厚皮片。1996年6月至1999年5月,8例患者接受了该手术。所有筋膜瓣及覆盖的全厚皮片均存活良好。我们技术的优点包括稳固的抬高、良好的正面突出以及耳廓后侧自然的外观。此外,通过采用这种快速实用的方法,我们避免了在头皮上产生额外的瘢痕,并保留了颞浅顶筋膜和颞浅血管。
