ABSTRACT
Objective@#To investigate the therapeutic effect of levator muscle combined with Müller′s muscle shortening for treatment of mild and moderate congenital blepharoptosis.@*Methods@#Thirty-one cases (38 eyes) with mild or moderate congenital blepharoptosis were treated through both skin and conjunctiva approach. The levator muscle was exposed through skin approach. The Müller′s muscle was separated from conjunctiva through conjunctiva approach. The combined flap of levator muscle and Müller′s muscle was freed from the upper edge of tarsus and shortened. Then the combined flap was fixed on the upper 2/3 portion of tarsus to correct the ptosis.@*Results@#All the patients were followed up for 6-24 months with satisfactory result . The result was graded as good 12 eyes, generally 21 eyes, inadequate correction 3 eyes, over-correction 1 eye, and nvalid correction 1 eye. The effective rate was 86.8%.@*Conclusions@#The levator muscle combined with Müller′s muscle shortening is a very simple and practicle method for mild to moderate congenital blepharoptosis with satisfactory result.
