We studied 68 cases of orbital blowout fracture in our department from October, 1981 to March, 1997. There were 58 males and 10 females (mean age 22.6 years). Sinus CT scan and Hess test were done before operation, and surgery was performed in 66 cases under general anesthesia. Seven cases of medial orbital wall fracture were treated by extranasal approach and 1 case of medial orbital wall fracture was treated by intranasal approach. In 40 cases of orbital floor fracture, approach from eyelid, or transantral, or a combination of these two were used. Defects of the orbital wall were reconstructed with autogenous bone grafts of the antherior wall of the maxillary sinus, or orbital floor, or iliac bone. Postoperative improvement of double vision was better in patients having surgery within two weeks of the injury than in those having surgery more than two weeks after injury.
