Use of orbicularis oculi muscle flap for undercorrected blepharoptosis with previous frontalis suspension.

The frontalis muscle and its fascia are connected with the orbicularis oculi muscle at the level of the eyebrow. Therefore, the superiorly based orbicularis oculi muscle flap, when advanced and attached to the tarsal plate, can dynamically elevate the upper lid and correct blepharoptosis with previous frontalis sling. Six patients with undercorrected blepharoptosis after frontalis sling suspension were included in this study. The superiorly based orbicularis oculi muscle flap was advanced to the tarsal plate in these patients and the redundant portion of the distal flap was resected. Postoperative results were satisfactory after 1-year follow-up.
