Skin under tension with "creep", i.e. stretch. This probably accounts for the fact that by far the commonest postoperative complaint of face-lift patients is of inadequate lift. Creep occurs within a few hours of the operation but is at first masked by postoperative oedema. At the second stage half as much or more skin as was excised on the first occasion may be re-excised. The conservative face-lift incision which spares the sideburns is the most conventient for the 2-stage operation.
皮肤在张力作用下会“蠕变”,即伸展。这可能解释了这样一个事实,即到目前为止,面部提升患者最常见的术后抱怨是提升不足。蠕变在手术后几小时内就会发生,但起初会被术后水肿掩盖。在第二阶段,可能会再次切除与第一次切除量相同或更多的皮肤。保留鬓角的保守面部提升切口最适合二期手术。
