This study concerns 10 patients with blow-out fractures of the orbital floor operated via both transeyelid and Caldwell-Luc approach. All patients had positive forced duction test and diplopia, 6 patients had enophthalmos, 5 patients had infraorbital numbness, 3 patients had periorbital swelling and 1 patient had periorbital emphysema, preoperatively. Evaluation of these fractures included history, physical examination, and radiographs. Preoperative evaluation of CT, the average size of fractures in the orbital floors was 10.8×14.5mm. In 8 patients of these, fractures in the orbital floors were localized anterior 1/3 or midportion, 1 of other 2 patients had combined infraorbital rim fracture and the other patient had fracture extended posteriorly. The operations were carried out within 10-15 days after trauma via both transeyelid and Caldwell-Luc approach. Evaluation of patients after operations, 3-6 months, 1 patient have had persistent diplopia who had combined infraorbital rim fracture, other 9 patients have not discovered any problems. Although orbital fractures should not be routinely explored, each should be viewed with its own merit and Caldwell-Luc approach developed if there is clinical evidence of a blow-out fracture.
