The prevention of scleral show is truly one of plastic surgery's Holy Grails. This postoperative problem may be considered subtle, but it represents the most common cause of the "operated" look that we all strive to avoid. Of course, the postoperative fear of a true ectropion is all too common. These concerns, borne out in patient results following the traditional skin-muscle technique, are what drove the author to consider the "pinch" blepharoplasty.
All patients who were candidates for a lower blepharoplasty, primary or secondary, underwent the pinch blepharoplasty. Patients excluded were only those who underwent a carbon dioxide laser resurfacing of the lower eyelid, as no skin excision was planned.
Of the 77 blepharoplasties performed, there were no postoperative findings of lower eyelid malposition: no taping was necessary, no significant scleral show was evident, and no ectropion was produced. There was also noticeably less bruising and swelling postoperatively with this technique. Moreover, it was apparent that the crepe-like skin at the lower eyelid was often fully effaced or improved significantly.
The pinch blepharoplasty has proved to be a superior approach to lower eyelid rejuvenation. This series suggests that with this technique significantly more crepe-like skin can be removed with reliably less chance of scleral show.
预防巩膜外露确实是整形手术的一大难题。这个术后问题可能看似不明显,但却是我们都极力避免的“手术痕迹”的最常见原因。当然,术后对真正睑外翻的担忧也很常见。传统皮肤肌肉技术术后患者的这些情况,促使作者考虑采用“捏提”法睑成形术。
所有适合行初次或二次下睑成形术的患者均接受捏提法睑成形术。仅将那些计划进行下睑二氧化碳激光表面重塑的患者排除在外,因为不打算切除皮肤。
在施行的77例睑成形术中,未发现术后下睑位置异常:无需包扎,无明显巩膜外露,也未产生睑外翻。采用该技术术后的瘀斑和肿胀也明显减轻。此外,很明显下睑的皱纹样皮肤常常完全消失或明显改善。
捏提法睑成形术已被证明是下睑年轻化的一种更优方法。该系列研究表明,采用这种技术能去除更多皱纹样皮肤,同时巩膜外露的可能性可靠地降低。
