Endoscopic endonasal reconstruction of blowout fractures of the medial orbital walls

High-resolution endoscopes and the advent of endoscopic instruments for sinus surgery currently provide surgeons with excellent endonasal visualization and access to the medial orbital walls. The purpose of this study was to demonstrate the reduction of medial orbital wall fractures through an endonasal endoscopic approach that allows the repair of the medial orbital wall fractures out an external incision. This Study was a retrospective analysis of 16 patients who underwent surgical repair of medial orbital wall fractures from March of 1997 to May of 1998. The 11 male and five female patients ranged in age from 16 to 54 years (mean, 30.5 years). These patients had undergone primary reduction of medial orbital wall fractures and were observed for at least 12 months after surgery. There were no intraoperative or postoperative complications. Fifteen of 16 patients showed a complete improvement of their symptoms. One patient showed persistent diplopia, which was well managed by prisms. Endoscopic reduction of medial orbital wall fracture using an endonasal approach seems to produce good results and definite cosmetic advantages.
