    Abstract:
    PURPOSE: To present a case series review of management of pure orbital floor fractures and propose a protocol. METHODS: A retrospective review of medical records and computed tomography (CT) scan findings was completed. Fractures were classified into either trap-door, floor-fracture with incarcerated tissue, or depressed floor-fragment fractures. Criteria for surgical success were: enophthalmos <1mm; no hypoglobus/hyperglobus; extra-ocular muscle restriction <5° in upgaze but normal in all other positions on Hess chart; and no diplopia other than in extreme upgaze (5°). RESULTS: A total of 79 patients with orbital floor fractures were identified. There were 6 trap-door type fractures, 42 floor fractures with incarcerated tissue, and 31 depressed floor-fragment type fractures. Thirty-six patients were managed conservatively (antibiotics and observation). In nine of these, surgery was avoided by adhering to our protocol of delayed repair. Forty-three had surgical intervention: 6 were trap-door-type, 18 had a floor fracture with incarcerated tissue and 19 were of the depressed floor-fragment variety. All trap-door fractures underwent early repair (6/43, 14%), the rest had delayed repair (37/43, 84%). Four of 6 trap-door fractures had a successful outcome (66.6%). All 18 fractures with incarcerated tissue underwent successful delayed repair. Seventeen of 19 patients with depressed floor-fragment fractures were treated successfully surgically. The follow-up ranged from 12-64 months. The overall success rate was 85.3%. CONCLUSION: Non-trap-door type of floor fractures can have a successful outcome with delayed repair. This can avoid unnecessary surgery in selected cases. A management protocol is proposed.
