ABSTRACT

Objective To discuss the effect of an advanced technique by shortening the levator palpebrae superioris muscle in treatment of moderate and severe congenital blepharoptosis. Methods 30 cases of moderate and severe blepharoptosis (including 2 cases of recurrent ptosis) were treated by shortening the levator palpebrae superioris associated with resection of tarsus. Removal portion of tarsus and levator palpebrae superioris muscle was designed according to the width of tarsus and the severity of blepharoptosis. Tarsus and levator palpebrae superioris muscle and conjunctiva palpebrae were resected on the basis of above design. The results of postoperation were followed up. Results Among the 30 cases, except for undercorrection in 3 cases, all others had a good outcome. Eyelid was raised to normal level by this technique with a natural eyelid contour. Only some presented a slight dysraphism in the early stage of postoperation,and no other severe complications occurred. Conclusions Shortening of the levator palpebrae superioris muscle can be applied to treat moderate and severe congenital blepharoptosis, and correct the deformity and achieve cosmetic effect simultaneously.In order to achieve satisfactory effects on function and shape, we should master the main points of operation.
