Delayed Enophthalmos Following a Minimally Displaced Orbital Floor Fracture

Abstract

In Brief We describe a case of an orbital floor fracture resulting in obstruction of the maxillary sinus ostium by herniated orbital contents. Our patient had delayed enophthalmos in a manner similar to silent sinus syndrome or imploding antrum syndrome. Obstruction of the maxillary sinus ostium by orbital contents carries the potential for delayed-onset enophthalmos and therefore suggests an additional indication for orbital floor fracture repair. Obstruction of the maxillary sinus ostium by orbital contents after orbital floor fracture resulting in a silent sinus-like syndrome may be an indication for orbital floor fracture repair.
