Reconstruction of the anophthalmic socket: lower eyelid malposition and canthal tendon laxity.

There are a number of etiologies underlying the development of socket deformity with associated lower eyelid malposition, lateral canthal tendon laxity, and/or contraction of the inferior fornix. In addition to cosmetic considerations, each of these anatomic problems can interfere with comfortable wear and retention of a prosthesis. This chapter gives an overview of these problems and details our preferred surgical approaches to repair of these anatomic deformities. Specifically discussed are techniques for: mucous membrane and ear cartilage grafting to repair lower lid inner lamellar tissue shortage, reconstruction of the inferior fornix/cul-de-sac, direct lower eyelid lateral canthal resuspension, and resuspension using a periosteal flap or autogenous fascia lata from the iliotibial tract.
