颞顶筋膜瓣与扩张皮瓣联合覆盖Medpor支架外耳再造术

目的探讨颞顶筋膜瓣与扩张皮瓣联合覆盖Medpor支架再造外耳的效果。方法手术分两期进行:一期手术在乳突区置入皮肤软组织扩张器,并定时注水扩张;第二期手术将扩张器取出并形成蒂在前的扩张皮瓣、掀起以颞浅血管为蒂的颞顶筋膜瓣,应用颞顶筋膜瓣和乳突区扩张皮瓣双重由里至外覆盖Medpor耳支架完成耳廓再造。结果临床应用22例,随访半年至2年半,无耳支架外露发生,再造的耳廓外形逼真,轮廓分明,肤色与周围正常皮肤一致。结论应用乳突区扩张皮瓣及颞顶筋膜瓣双层组织瓣包被Medpor耳支架,可以提高Medpor耳支架置入的安全性,避免发生外露,又不影响支架外形和轮廓的显现,再造耳表面皮肤的色泽与周围皮肤一致。

Medpor外耳再造术皮肤覆盖方案的临床研究

目的:本文通过比较几种不同的支架外皮肤覆盖方案,探索一种手术效果稳定可靠的合成材料支架外耳再造方法。方法:48例先天性小耳畸形,应用Medpor支架行全外耳再造术,支架外软组织覆盖材料分别为单纯乳突区扩张皮肤1例、颞顶筋膜瓣加植皮25例、乳突区扩张皮瓣加颞顶筋膜瓣22例,观察比较应用不同覆盖材料耳再造后支架外露发生率、再造外耳外形轮廓、表面皮肤颜色质地。结果:临床应用48例,随访1至6年,应用单纯乳突区扩张皮瓣覆盖者1年内耳支架完全外露;应用颞顶筋膜瓣加植皮者再造耳廓外形及轮廓优良,但大部分病例再造耳廓皮瓣不同程度色素异常;应用乳突区扩张皮瓣及颞顶筋膜瓣联合覆盖者再造外耳形态及轮廓均优良,且表面皮瓣颜色质地与周围皮肤和对侧外耳皮肤一致,美容效果最佳。结论:应用乳突区扩张后皮瓣及颞顶筋膜瓣双层组织瓣的软组织覆盖方案可以满足Medpor再造外耳的外形、轮廓及皮色的需求,是一项安全稳定的手术方案,综合效果优于颞顶筋膜瓣加植皮方案,而单纯应用乳突区扩张皮瓣的方案不适用于Medpor外耳再造术。因此推荐在选用Medpor耳支架行全外耳再造治疗Ⅲ度先天性小耳畸形时,优先选用颞顶筋膜瓣联合乳突区扩张皮瓣的软组织覆盖方案。     

预制扩张耳后乳突区复合筋膜皮瓣在全耳再造中的应用研究

目的：研究采用预制扩张耳后乳突区复合筋膜皮瓣行全耳廓再造的方法和效果。方法：手术分二期完成。I期手术：设计带有颞浅动静脉蒂的颞顶筋膜瓣,移植入残耳乳突区皮下腔穴,然后置入皮肤扩张器,与耳后皮瓣进行同时同步扩张I;I期手术：将预制扩张的耳后乳突区复合筋膜皮瓣掀起,覆盖于Medpor支架上,进行全耳廓再造术。结果：36例患者经6个月～3年的随访,再造耳廓外形逼真,立体感强,与周围皮肤颜色相同,微细结构清晰。结论：采用预制扩张的耳后乳突区复合筋膜皮瓣＋Medpor支架行全耳再造,具有创伤小,操作方便,效果满意。既可避免支架外露,又可避免取自体肋软骨增加的创伤和痛苦或肤色差异等优点,是目前全耳廓再造术较为理想的选择方法。

扩张皮瓣联合Medpor耳支架全耳再造的临床研究(附8例报告)

目的:应用扩张皮瓣联合Medpor耳支架行全耳再造术,使耳再造成形逼真,立体感强,手术时间缩短,减少创伤,探讨如何防治Medpor耳支架外露。方法:先在耳缺损区埋置扩张器,定期注水,扩张两个月后,取出扩张器。将Medpor耳支架依照健侧耳廓为模型进行雕刻,塑形后,置入耳缺损区扩张皮瓣后面(耳后乳突区),耳支架后缘用颞浅筋膜瓣及耳后筋膜瓣包埋,植皮,全耳再造成功。结果:共完成此手术8例(男6例,女2例),耳成形良好,手术效果满意,扩张皮瓣覆盖组织与Medpor耳支架贴合紧密,且外形显现良好,耳廓形态逼真。其中仅1例耳支架后方绿豆大小外露,经局部修复痊愈。结论:扩张皮瓣联合Medpro耳支架全耳再造术,形态逼真,立体感强,耳廓形态稳定,远期不易变形,与使用肋软骨支架相比,无切取肋软骨之苦,且手术时间明显缩短。不足:MedPor耳支架价格昂贵,弹性较差,易外露。

目的:探讨采用颞顶筋膜瓣与耳后筋膜皮瓣(简称:耳后联合双层筋膜瓣),Medpor支架行先天性小耳畸形全耳再造术的方法和效果。方法:采用颞顶支为血管蒂的岛状筋膜瓣移转至残耳乳突区耳后,与耳后乳突区筋膜皮瓣同期同步进行扩张,然后将扩张的耳后联合双层筋膜皮瓣包裹Medpor支架行全耳廓再造。结果:本组患者中经3个月~3年的随访,再造耳皮肤颜色与耳周缘面部相接近,微细结构清晰,颅耳角与健耳对称,形态结构好。结论:耳后联合双层筋膜瓣+Medpor支架行全耳廓再造,既能有效避免支架外露和传统手术供区胸壁畸形,又能避免切取自体肋软骨增加的创伤及痛苦。再造耳皮肤颜色与正常肤色相似,形态满意,是一种值得推广的手术方法。     

乳突区双扩张器重叠埋置在全耳廓再造术中的应用

目的 介绍应用两个皮肤软组织扩张器叠加埋置的方法进行全耳廓再造的临床经验。方法 自2008年1月至2011年12月,共27例小耳畸形患者实施该方法。一期手术在患侧乳突区埋置肾形皮肤软组织扩张器80 mL（或100 mL） 和50 mL 各一个,将体积大的扩张器叠加放置在体积小的扩张器之上,术后定期交替扩张器注水3～6月。二期手术全部采用Medpor人工耳廓支架,取出扩张器,将扩张的皮瓣直接包裹支架,负压维持耳廓成形。结果 随访时间4～50月,27例再造的耳廓外形位置良好,皮肤质地与周围皮肤相近,颅耳沟稳定无回缩,扩张皮瓣无坏死。2例患者因伤口裂开发生耳廓支架外露(7.4%),进行一次修补手术后恢复良好。结论 乳突区叠加埋置两个扩张器全耳廓再造术,避免了植皮,不再使用耳后筋膜瓣和颞筋膜瓣,手术过程简单化,缩短了手术时间,部分再造耳廓亚单位欠清晰,但总体效果满意。     

Flag flap - Kite flap Dorsal metacarpal flap

The flag flap is a pedicled dorsal digital flap, combining a skin paddle (the “flag”) and a vascular pedicle (the flag “pole”). Its vascularisation depends on the dorsal metacarpal arteries (DMCA). It has been described in 1963, by Holevitch [1] with harvest of a cutaneovascular pole; it has been brilliantly modified in 1979 by Foucher et al. [2–4] under the form of a unipedicled “kite” flap, although we would like to point out that Vilain has been using it since 1952 [5]. Usually harvested from the dorsum of the metacarpophalangeal region of the index finger, this flap is reliable, but it is more uncertain and less movable at the level of the other digits. Owing to its small size, it proves useful in hand traumatology because it does not sacrifice any major vascular axis. The kite flap is considered as a sensory flap (presence of a nerve supply) with a two-point discrimination, which can be assessed from 11 to 16 mm [1–6].     

Recycling a flap: Making a perforator flap from a previous gluteal fasciocutaneous flap

Abstract

We report a case of raising a previous gluteal fasciocutaneous flap again as a perforator-based flap to cover a recurrent defect. This case illustrates that conventional flap tissue with a preserved perforator can be recycled as a perforator flap, and that this method can be an efficient surgical option for recurrent defects.     

McGregor flap

Since it has been described in the early seventies [1], this flap has become an essential tool in reconstructive surgery, primarily due to the wide cutaneous surface it may replace. Its pediculate form is useful and it may be employed with significant benefit as free flap; it may even provide composite tissues. Also known as McGregor’s flap, groin flap, or iliofemoral flap, this axial pattern flap is based on the superficial iliac circumflex artery.     

V-Y advancement flap out of an existing flap

A case is reported in which a large V-Y flap was fashioned out of a flap already present over the dorsum of the hand, to cover a defect created adjacent to it. The V-Y advancement appeared more effective to fill the defect than the traditional method of mobilisation of a part of the flap achieved by dissecting it from its base.

Atasoy flap

Fingertip tissue loss is frequent. It often requires a reconstruction with a flap in case of exposure of the distal phalanx. We will present the technique of reconstruction by means of a local pedicle flap described by Atasoy. It is a local bipedicled flap harvested from the fingertip. The incision is triangular or volar without exceeding the palmar fold of the distal interphalangeal. Laterally, it is located 2 millimetres from the lateral nail folds. The flap is detached from the phalanx on its deep aspect. When the flap is released it can protrude from 5 to 7 millimetres. The flap covering the phalanx is then fixed by means of an intradermic needle and sutured laterally. The needle and the stitches are removed between the 2^nd and the 3^rd postoperative week. Physiotherapy will start the day following the surgery. There should be a relative abundance of remaining fingertip tissue so that it will be able to cover the phalanx; this technique is recommended in both the strictly transverse and dorsal oblique amputations. Among the most common undesired effects we have sensory changes, temporary pains in the fingertip pulp space and the palmar retraction of the flap if not properly fixed. However, this flap is still reliable and can be reproduced; it gives excellent cosmetic appearance if it is set correctly.
