AIM:To analyze the causes of recurrence congenital ptosis and guide the choice of surgical procedure again.METHODS:Previous surgical procedures before surgery was understood, reasons for failure was analyzed, and according to levator muscle strength of upper eyelid combined with medical history, surgical method was re-established. Based on the levator muscle strength, considering the previous surgical operations, for the levator muscle strength ≤4mm, frontalis flap suspension was introduced; for the levator muscle strength ≥6mm, levator shortening was introduced; for the levator muscle strength between 4-6mm, if they used frontalis in previous surgery, levator shortening and fromtal muscle flap suspension might be introduced. We have used fromtal muscle flap suspension.RESULTS:A total of 26 cases 30 eyes patients had no eyelid margin arc deformity,natural double eyelid,the upper palpebral margin located 1-2mm down upper corneal margin, or symmetric with the health eye.CONCLUSION: Recurrent congenital ptosis resurgery was re-established with surgical method according to levator muscle strength combined with medical history.
