Late proptosis is an unusual complication of orbital floor fracture repair. We report 12 cases and propose a classification scheme and differential diagnosis for this rare complication.
Retrospective multi-institutional case review.
Two tertiary referral centers.
We report 12 cases of late proptosis following orbital floor fracture repair. Causes of late proptosis include peri-implant inflammation, capsular hemorrhage, gelatin film cyst, implant infection, sino-orbital fistula, intraorbital sinus mucocele, and carotidcavernous fistula. We describe the treatment of each case individually; in most cases, the implant was removed. All 12 patients had a satisfactory outcome after treatment.
Proptosis presenting 2 months or more after orbital floor fracture is rare. We classify the origin of late proptosis into three groups: implant, sinus, and neurovascular. We describe the diagnosis and management of this unusual complication.(Arch Otolaryngol Head Neck Surg. 1995;121:649-652)
