| Summary | Silicone implants are an important material for the reconstruction of orbital wall defects. However, surgeons prefer to use other materials due to numerous reports of silicone implant complications, including infection, extrusion, and implant displacement. Cyst formation, particularly hemorrhagic pseudocysts, are most often reported as a late complication.
We presented a patient who developed an orbital cyst 18 years after orbital floor reconstruction with a silicone implant. The orbital cyst caused significant exophthalmos and restriction in ocular motility. Surgical excision revealed a cyst that was displacing the globe and encapsulating the silicone implant. On histopathologic examination, the cyst was lined with squamous epithelia. This case report demonstrates that although an uncommon complication, squamous epithelium-lined inclusion cysts may develop several years after orbital floor fracture repair with a silicone implant. |
