Endoscopic, endonasal management of fractures of the medial orbital wall
It is well known that fractures of the orbital floor are more frequent than those of the medial wall. The reason is that the most delicate part of the orbit is the lamina papyracea. High resolution CT has helped make this diagnosis more precise and permits us visualize the region surrounding the lamina papyracea with greater detail. Conventionally, fractures of the medial orbital wall have been corrected with transorbital techniques through an external incision and a maxiloethmoidal approach. An orbital fracture with lesions of the delicate intraorbital structures can be a complication of endoscopic paranasal sinus surgery when previous procedures have changed the patient’s anatomy, or when the surgeon is not adequately trained and fails to realize he has entered the orbit. The use of motor driven instruments may also cause complications with devastating damage to this area. Endoscopic, endonasal approaches for the reconstruction of the medial orbital wall and the orbital floor using a computer assisted imaging navigational system is a great help, and it eliminates the external skin incision.
