To assess the efficacy and predictability of a minimal incision posterior approach levator plication technique for correction of involutional ptosis.
Retrospective chart review of patients with involutional aponeurotic ptosis underwent minimal incision posterior approach levator plication technique between August 2013 and June 2014 by a single surgeon. The upper lid was double everted, and the conjunctiva and Muller's muscle layers were incised vertically until the levator aponeurosis could be identified. The incision(s) was similar to performing incision and curettage of chalazion, except that the site was above the tarsal plate and extended towards the fornix. Then insertion of aponeurosis was dissected away from the anterior tarsal surface, and the more superiorly located levator was plicated on it with double arm suture(s). No tissue was excised in this procedure. Surgical success was defined as a postoperative margin reflex distance (MRD)>2 mm and<4.5 mm, interlid height<1 mm and satisfactory contour.
Forty-four lids of 27 patients were included. Preoperative mean MRD was 0.48 +/- 0.56 mm. Severe ptosis of MRD<1 mm was present in 34/44 patients (77.3%). The postoperative mean MRD was 2.49 +/- 0.53 mm, and mean improvement was 2.02 +/- 0.61 mm, which was statistically significant (P<0.001). The overall success rate was 38/44 (86.4%).
Minimal incision posterior approach to levator plication was effective for the correction of aponeurotic ptosis with moderate to good levator function.
评估小切口后路提上睑肌折叠术矫正老年性上睑下垂的疗效及可预测性。
回顾性分析2013年8月至2014年6月期间由同一外科医生采用小切口后路提上睑肌折叠术治疗的老年性腱膜性上睑下垂患者的病历。上睑双重翻转,垂直切开结膜和米勒肌层,直至能识别提上睑肌腱膜。切口类似于睑板腺囊肿切开刮除术,只是位置在睑板上方并向穹窿延伸。然后将腱膜插入部分从睑板前表面分离,用双臂缝线将位置较高的提上睑肌折叠缝合于其上。该手术不切除任何组织。手术成功定义为术后边缘反射距离(MRD)>2mm且<4.5mm,睑裂高度<1mm且外形满意。
纳入27例患者的44只眼睑。术前平均MRD为0.48±0.56mm。44例患者中有34例(77.3%)存在MRD<1mm的重度上睑下垂。术后平均MRD为2.49±0.53mm,平均改善值为2.02±0.61mm,差异有统计学意义(P<0.001)。总体成功率为38/44(86.4%)。
小切口后路提上睑肌折叠术对于矫正具有中度至良好提上睑肌功能的腱膜性上睑下垂有效。
