The 50 patients (85 eyelids) underwent the advancement technique using the levator aponeurosisMllers musclelamina propria mucosa of conjunctiva composite flap. l Twenty-one of 50 patients (42 percent,
10、 42 eyelids) had epicanthal folds with associated telecanthus and therefore underwent epicanthoplasty and shortening of the medial canthal tendon.18Operative Techniquel The double eyelid incision line is marked on the upper eyelid 6 to 9 mm above the lid margin, depending on the personal preference
11、of patients without double eyelids.l Modified V-W plasty is designed on the skin medial to the epicanthal folds of patients with blepharoptosis and epicanthal folds with associated telecanthus.l Epicanthal folds with associated telecanthus are corrected before ptosis correction is performed. l The o

Of these patients, 38 (76 percent) had congenital ptosis and 35 (70 percent) had bilateral ptosis. Of the 35 pati
