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 of 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 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. (Korean J Otolaryngol 38:11, 1995)
