Repair Techniques For Fail Double Eyelids Involving Restoration Of Eyelid Anatomical Structure And Function

Objective:This study aimed to evaluate techniques for repairing previously failed double eyelid surgeries based on different anatomical structure injuries.Methods:A total of 120 patients with failed double eyelids in our hospital were enrolled and classified into four types according to their anatomical structure damage: type I,unsmooth radians of the double eyelid line;type II,upper socket depression;type III,iatrogenic ptosis;and type IV,comprehensive damage.Accordingly,methods of restoration included orbital septum fat supplement,repair of levator palpebrae superioris,and treatment of scar.Postoperative follow-up time points were 1 week,1 month,and 6 months.Outcome observations were binocular symmetry,fluency of double eyelid,scar recovery,height and contour profile of the upper eyelid margin,and plumpness of the upper eyelid.The eyelid morphological score was evaluated using photographs of preoperative and 6-month postoperative data,and the effect of eyelid repair was evaluated objectively by statistical analysis.Results:At 1 month after surgery,the height of the upper palpebral margin was maintained in most patients and located at 1–2 mm below the superior limbus.At 6 months after surgery,most patients had better restorative effects.Comparison of mean eyelid morphological scores showed statistically significant improvement following surgery(p<0.001).Conclusions:The technique of restoring eyelid anatomical structure in failed double eyelids not only recovered the normal function of injured eyelid but also produced satisfactory aesthetic effects.
