The incision from the lateral canthal angle is marked to extend laterally and vertically following the curve of the lower eyelid (for upper lid defects, this curve is reversed to follow the upper eyelid). A small primary skin incision is made with a #15 scalpel blade from the angle of the lateral canthus following the markings for 8 mm. Westcottโs scissors are used to release the firm lateral canthal attachment of the lower lid with a canthotomy passing through the inferior crus of the lateral canthal tendon. A pocket is made with the scissors on each side of the septum, and then with the lid under medial tension; the tip of the scissors is used to feel for the tight septal fibers by drumming
across them. The cantholysis can then be progressively released by making small nibs with the scissors until the wound can be easily closed. An overlap of 2 mm represents perfect tension. The tarsal plate is then closed primarily with a standard diagonal suture technique and the skin and muscle of the primary defects are closed in a layered manner. As the lateral incision is pulled medially, it usually closes automatically and does not usually require a suture.
