Abstract
We report 3 cases of blow-out fracture treated by a combination of transantral and infraorbital approaches with open reduction. Each case had facial trauma associated with enophthalmos and diplopia. CT examination revealed fractures of the orbital floor and blow-out of the orbiatal content toward the antrum. The transantral balloon technique combined with infraorbital open reduction using iliac bone grafting was applied in these 3 cases and the outcomes were quite successful in all cases. We consider that collaboration between otolaryngologists and plastic surgeons is important for the treatment of fractures of the orbital floor.
