In brow lift, if a direct approach is utilized, the suture line medially is placed in a normal frontalis crease, and then the lateral part of the suture line, by lateral transfer of a small superiorly based flap, is caused to fall into a natural "laugh line" or "crow's feet" crease, three improvements result: 1. Greater control and predictability of shaping and position than with other techniques; 2. A more normal appearance, including better lateral lift and a much more inconspicuous scar than with supraciliary direct lift; 3. A longer-lasting result. In approximately 150 patients, scar appearance has been very gratifying indeed, with only 3 limited segmental scar revisions and 2 secondary midforehead elliptical excisions. It is believed that the principle exhibited in the tightening of the upper suture line by flap transfer, referred to by analogy as the worm principle, accounts for much of the improvement, especially in durability. This principle is seen as an aid in thinking through the mechanics of several other plastic surgical situations as well.
在提眉术中，如果采用直接入路，内侧缝线置于正常的额纹处，然后通过向上蒂小皮瓣的外侧转移，使缝线外侧部分落入自然的“笑纹”或“鱼尾纹”皱褶中，会产生三个改进效果：1. 与其他技术相比，对塑形和位置的控制和可预测性更强；2. 外观更自然，包括比眉上直接提升术有更好的外侧提升效果且瘢痕更不明显；3. 效果更持久。在大约150例患者中，瘢痕外观确实非常令人满意，仅进行了3次有限的节段性瘢痕修复和2次额部中部继发性椭圆形切除。据信，通过皮瓣转移收紧上缝线所展现的原理，类比称为蠕虫原理，很大程度上解释了这种改进，尤其是在持久性方面。该原理也被视为有助于思考其他几种整形手术情况的力学原理。
