To report a refinement of small-incision external levator advancement with a standardized method for suture placement for correction of acquired blepharoptosis and 1 surgeon's results with this technique.
Retrospective medical record review of data from all patients with unilateral or bilateral acquired blepharoptosis who underwent small-incision external levator advancement from October 1, 2007, through January 31, 2011.
Ninety-two eyelids from 66 patients with acquired blepharoptosis were treated with small-incision external levator advancement with uniform suture placement. Forty patients underwent unilateral surgery and 26 underwent bilateral surgery. The mean preoperative margin-to-reflex distance was 0.70 mm. The mean postoperative margin-to-reflex distance was 2.95 mm. Symmetry was achieved in 49 patients (74%) on the basis of a less than 1-mm difference in margin-to-reflex distance. When stratified by unilateral ptosis repair vs bilateral ptosis repair, bilateral ptosis repair achieved greater symmetry on average (81% vs 70%). Nine patients underwent revision. There were only 2 postoperative complications: one was postoperative upper eyelid bleeding and the other was exposure keratopathy.
The simplified method of suture placement for small-incision external levator advancement is an effective, safe, and efficient option for acquired ptosis correction.
报告一种改良的小切口提上睑肌前徙术，采用标准化的缝线放置方法来矫正后天性上睑下垂，并介绍一位外科医生使用该技术的治疗结果。
对2007年10月1日至2011年1月31日期间所有接受小切口提上睑肌前徙术治疗单侧或双侧后天性上睑下垂患者的数据进行回顾性病历审查。
66例后天性上睑下垂患者的92只眼睑接受了小切口提上睑肌前徙术，并采用了统一的缝线放置方法。40例患者接受了单侧手术，26例接受了双侧手术。术前平均边缘至反射距离为0.70毫米。术后平均边缘至反射距离为2.95毫米。基于边缘至反射距离相差小于1毫米，49例患者（74%）实现了对称。按单侧上睑下垂修复与双侧上睑下垂修复分层时，双侧上睑下垂修复平均实现了更高的对称性（81%对70%）。9例患者接受了修复手术。术后仅出现2例并发症：1例是术后上睑出血，另1例是暴露性角膜病变。
小切口提上睑肌前徙术的简化缝线放置方法是矫正后天性上睑下垂的一种有效、安全且高效的选择。
