Intraorbital squamous epithelial cyst: an unusual complication of Silastic implantation

Thin Silastic sheet alloplasts (Dow Corning, Midland, MI, U.S.A) are commonly used to reconstruct posttraumatic orbital floor defects. Complications associated with orbital Silastic implantation include infection, migration, and extrusion. The authors report an unusual case of an intraorbital, squamous, epithelial-lined cyst appearing as progressive vertical globe dystopia and proptosis occurring after Silastic reconstruction of a traumatic orbital floor defect.
