Abstract
There are two different approaches for the reduction of blow-out fractures of the orbital floor, one is through Caldwell-Luc's approach and the other is via the lower eye lid. We have used another approach for the reduction, which is through the middle nasal meatus and fontanelle using a balloon catheter in endoscopic endonasal surgery. We have obtained a good result by this approach. The patient 28-year-old male, diplopia was main complaint. The fracture was only in the floor of the orbit. We diagnosed the fracture on the CT. The number of days between the fracture and operation was seventeen days.
The reduction was performed under endoscopic control, then a Foley-type balloon catheter was inserted through the middle nasal meatus and fontanelle under the microscope. Then the balloon catheter was inflated with water replacing the fracture segments and the orbital contents. The balloon was held in place for ten days. After this treatment diplopia of the case was improved, which was confirmed by an ophthalmologist.
There are numerous literature on the surgical treatment of blow-out fractures of the orbital floor. Usual approach is through Caldwell-Luc's procedure or via the lower eye lid.
Endoscopic endonasal approach has been found to be a useful procedure for the reduction of blow-out fracture of the orbit.
