In the past 3 years, more than 125 patients have undergone primary and secondary lower blepharoplasty by the transconjunctival method. The ability to adequately remove fat with this approach has been impressive. Exposure of the central and medial fat compartments is excellent. The lateral fat pad area is not as easy to visualize, and care must be taken to assure that adequate fat removal is achieved. Although one might suspect that postoperative conjunctival irritation could be a problem with this procedure, this has been notably absent in our patient population. In addition, there have been remarkably few patients with dry eye complaints following transconjunctival lower blepharoplasty. The question of skin resection must also be addressed. Currently, we believe that the majority of patients seeking improvement of the lower eyelids benefit most by a transconjunctival blepharoplasty without skin resection (Figs. 3 and 4). When there is obvious skin excess, we believe that it is best approached by removing the fat through the transconjunctival incision and then removing skin with a simple skin flap or skin pinch technique. This must be done considerably more conservatively than has been recommended in the past, to retain a natural palpebral fissure. Secondary skin removal, if necessary, is a straightforward procedure that can be readily done under local anesthesia at a later date. Transconjunctival lower blepharoplasty has not been associated with prolonged (exceeding 1 month) lower lid retraction problems in any of our patients. The technique is easy to learn but does require some experience with the anatomy. The technique should become the basic procedure for correction of excess fat in the lower eyelids.
在过去3年中,超过125例患者通过经结膜入路接受了一期和二期下睑成形术。用这种方法充分去除脂肪的能力令人印象深刻。中央和内侧脂肪隔的暴露效果极佳。外侧脂肪垫区域不太容易看清,必须小心确保实现充分的脂肪去除。尽管有人可能怀疑术后结膜刺激可能是该手术的一个问题,但在我们的患者群体中明显没有出现这种情况。此外,经结膜下睑成形术后干眼主诉的患者非常少。皮肤切除的问题也必须解决。目前,我们认为大多数寻求改善下睑的患者通过不切除皮肤的经结膜睑成形术获益最大(图3和图4)。当有明显的皮肤多余时,我们认为最好的方法是通过经结膜切口去除脂肪,然后用简单的皮瓣或皮肤捏起技术去除皮肤。这必须比过去推荐的做法更加保守,以保留自然的睑裂。如有必要,二期皮肤切除是一个简单的手术,可以在以后很容易地在局部麻醉下进行。在我们的任何患者中,经结膜下睑成形术都没有与下睑退缩延长(超过1个月)的问题相关联。该技术易于学习,但确实需要一些解剖学经验。该技术应成为矫正下睑脂肪过多的基本手术方法。
