Flap elevation and inset
Flap elevation and inset
A horizontal incision is made approximately 2 to 3 mm beneath the inferior tarsal plate and extended full thickness through the lower lid. Westcott scissors are useful to reach the desired depth on this thin skin. The flap is completed by two parallel, vertical incisions and transferred under the inferior tarsal plate. The lower lid palpebral conjunctiva is carefully dissected off the orbicularis muscle and attached to the levator aponeurosis and edge of the upper lid conjunctiva. The surgeon may consider using auricular cartilage or a free tarsal graft on the top of the conjunctiva to add support.23 The skin and muscle of the lower eyelid flap are then advanced superiorly and sewn onto the upper lid in a layered fashion. The lower lid defect remains open.
