One theory in cheek-neck lifting is that it is necessary to undermine skin flaps widely to achieve adequate short and long term results. We have proven that extensive undermining allows no more skin to be excised than is permitted by more conservative undermining when snug skin closures are used. Another part of the theory is that a sheet of scar tissue ("favorable fibrosis") forms and that the larger sheet of scar from more extensive undermining maintains the improvement from the lift longer than would a smaller sheet from less undermining. Controlled studies presented here cast doubt on this part of the theory. Many years ago we ran a series on patients in whom one side had essentially twice as much undermining as did the other. Equal amounts of skin were removed on both sides. Short and long term results were essentially the same on the two sides.
脸颊颈部提升术的一种理论认为，有必要广泛剥离皮瓣以获得足够的短期和长期效果。我们已经证明，当采用贴合的皮肤缝合时，广泛剥离所切除的皮肤并不比更保守的剥离允许切除的皮肤更多。该理论的另一部分是，会形成一层瘢痕组织（“有利的纤维化”），并且更广泛剥离形成的更大片瘢痕组织比较少剥离形成的较小片瘢痕组织能更长时间维持提升效果。本文所呈现的对照研究对该理论的这一部分提出了质疑。许多年前，我们对一系列患者进行了手术，其中一侧的剥离量基本上是另一侧的两倍。两侧切除的皮肤量相等。两侧的短期和长期效果基本相同。
