Abstract

The authors repaired a medial blow-out fracture by using an endoscopic transnasal technique with a balloon catheter and Merocel packing in 17 subjects. The follow-up periods were from 6 weeks to 2 years, and averaged 6 months. The length of the operation was 50 minutes on average. The enophthalmos was corrected in seven of the eight patients. Supporting material for the fractured medial orbital wall was kept in place for 1 to 3 weeks. The mean volume of balloon inflation was 2 cc. The result was satisfactory. No complications resulted from the transnasal endoscopic technique. This endoscopic transnasal approach allows for a better aesthetic result because it eliminates external scarring and permits a direct approach to the medial orbital wall and has a superior visualization. A balloon catheter was used to support the fractured medial orbital fracture, which was adapted, ballooned, and then visualized using a radiopaque dye (Visipaque) in 11 cases. A postoperative computed tomographic scan revealed that this is a very useful method for controlling the status of the reduced orbital wall and eliminates the possibility of complications resulting from infection. A resected uncinate process was used as a bone graft material to repair the large defect in five cases. This method provides several advantages including a mucoperiosteal attached bone graft, working in the same operative field, and cost-effective surgical time. A transnasal endoscopic technique for medial orbital fracture is also very useful for releasing entrapment of the medial rectus muscle, because it directly pushes against the fractured wall and gives good exposure of the medial orbital wall.
