Conjoint fascial sheath suspension in treatment of severe blepharoptosis caused by inadequate suspension system tension / 中华医学美学美容杂志

ABSTRACT

Objective:To evaluate the safety and efficacy of conjoint fascial sheath (CFS) suspension surgery for severe blepharoptosis caused by low-tension suspension system.Methods:A total of 62 cases with severe blepharoptosis caused by low-tension suspension system received CFS suspension correction surgery from September 2014 to September 2017 were collected and followed up with a range of 12-36 months. The MRD-1, curve of upper eyelid, appearance and complications were recorded and underwent statistical analysis to evaluate the effect based on functionality, aesthetics and complication.Results:The postoperative MRD-1 was + 1 mm ~+ 4 mm compared with preoperative -3 mm ~+ 1 mm. The difference in the mean change was statistically different ( t=5.893, P<0.05). The satisfactory rate was 92.1% (82 cases), 7.9% (7 cases) were improved, and no case was invalid. There were no cases of recrudescence. Conclusions:Severe blepharoptosis can be caused by the inadequate tension of the upper eyelid suspension system. Laxity and abnormality of fixed structures may be major cause of decreasing levator aponeurotic tone. CFS suspension prevents further damage to the previous fixed structures, so it should be the first choice for such cases.
