Fig. 30. Sagittal diagram of the lower lid. An incision through skin and orbicularis can be placed in the subciliary area (1) or in a lower lid crease (2). In either case, dissection is carried through orbicularis to enter the postorbicular fascia plane on the anterior surface of the orbital septum. An incision through conjunctiva at the inferior border of the tarsal plate also leads into the postorbicular fascia plane, but from a posterior approach (3). An incision directly through the fornix gains access to the retroseptal space immediately (4).
