Transorbital endoscopic surgery

Orbital surgery is traditionally performed through an open approach and often involves bone removal for better visualization. The use of an endoscope obviates the need for bone removal in certain situations, particularly for lesions involving the orbital roof. Transorbital use of the endoscope also provides better visualization when one is working deep within the orbit, for instance, on the deep lateral wall. However, the endoscope can only be situated in the subperiosteal space, thus limiting its utility. In the article, the authors describe their technique for transorbital endoscopic surgery and review the uses and limitations of transorbital endoscopic surgery.
