Current goals in lower eyelid blepharoplasty include blending the lower eyelid-cheek junction, which is highlighted in the authors' six-step lower lid blepharoplasty technique. One major question in lower lid blepharoplasty is how to prevent lower lid malposition and ectropion, because these are untoward outcomes after an aesthetic procedure. In the authors' technique, they perform a superficial lateral retinacular canthopexy that is effective and safe and also prevents lower lid malposition or ectropion. A retrospective review of 104 patients who underwent six-step lower lid blepharoplasty was performed. In the authors' series, there was no significant difference between preoperative and postoperative intercanthal angles (p < 0.05), and the lateral canthal position did not change significantly from its preoperative position. The authors' six-step blepharoplasty technique addresses signs of midfacial aging, and the lateral canthopexy technique has been shown to have a minimal complication rate and maintains canthal position. CLINICAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, IV.
目前，下眼睑成形术的目标包括融合下眼睑 - 脸颊交界处，这在作者的六步下眼睑成形术技术中得到了强调。下眼睑成形术的一个主要问题是如何防止下眼睑位置不正和外翻，因为这些是美容手术后的不良后果。在作者的技术中，他们进行浅层外侧眼轮匝肌悬韧带固定术，这是一种有效且安全的方法，还可以防止下眼睑位置不正或外翻。对 104 名接受六步下眼睑成形术的患者进行了回顾性研究。在作者的系列中，术前和术后内眦角之间没有显著差异（p<0.05），外眦位置与其术前位置相比没有明显变化。作者的六步下眼睑成形术技术可以解决中面部衰老的迹象，并且外侧眼轮匝肌悬韧带固定术已经显示出较低的并发症发生率，并保持了眼轮匝肌的位置。临床问题/证据水平：治疗，IV。
