Lower eyelid and lateral canthal angle malposition or frank ectropion are the most common complications of lower eyelid blepharoplasty. Although these complications may result from excessive skin excision, from surgical imbrication of the orbital septum or lower eyelid retractors, or from scar formation within the eyelid, failure to correct preexisting lower eyelid laxity is the most common cause. Recently published data have established laxity at the lateral canthus as the primary cause of involutional lower eyelid laxity. We review the pathophysiology of lower eyelid laxity and present an anatomic approach for the correction of lower eyelid laxity during blepharoplasty.
下睑及外眦角错位或明显睑外翻是下睑成形术最常见的并发症。虽然这些并发症可能源于皮肤切除过多、眶隔或下睑缩肌的手术重叠，或眼睑内的瘢痕形成，但未能纠正术前存在的下睑松弛是最常见的原因。最近发表的数据表明，外眦角松弛是退行性下睑松弛的主要原因。我们回顾了下睑松弛的病理生理学，并提出一种在睑成形术中矫正下睑松弛的解剖学方法。
