The blepharoptosis is due to weakness of the levator palpebrea superioris. Many operative procedures were designed to correct blepharoptosis according to the patient's levator function. Author has treated 17 cases of blepharoptosis using fronto- orbicularis oculi muscle advancement technique in the 12 patients from September 1999 to August and followed up for this patient during mean 3 years about result of correction and complication. In long term follow up period, blepharoptosis is naturally corrected and other complication such as lagophthalomos, undercorrection are rare. In undercorrection case, it is easy to re-correct blepharoptosis because of easy dissection and simple advancement of previously dissected fronto-orbicularis oculi muscle flap. Fronto-orbicularis oculi muscle advancement technique is more advanced method to correct mild to severe blephatoptosis.
