title: Migrated orbital silastic sheet implant mimicking bilateral sinusitis.
abstract: We present a unique case of a migrated silastic sheet implant that was used during reconstruction of an orbital floor fracture, presenting as bilateral sinusitis. The patient had an orbital floor fracture that was repaired at a local hospital 20 years ago. An orbital silastic sheet implant perforated the bony nasal septum and migrated to the contralateral nasal cavity causing bilateral nasal symptoms. The silastic sheet was successfully removed during endoscopic sinus surgery. Therefore, ocular or nasal symptoms occurring in patients with a previous orbital wall fracture repair must be carefully evaluated clinically and radiologically with a suspicion of late complications, such as migration of the orbital implant.
