Abstract
Optic nerve decompression is performed for the relief of compression of the optic nerve with visual impairment caused by injuries to the face or head, neoplastic lesions in the orbit, or infectious lesions in the orbit. There are fundamentally three approaches to the optic canal: the skull route, the orbital route, and the nasal route. With regard to the disadvantages of each of these routes, the skull route requires a craniotomy procedure, which is highly invasive. The orbital route requires an incision to be made on the face, thus leaving a wound on the face. The nasal route involves complex dissection, and the surgical field of view is narrow. However, this disadvantage of the nasal approach has been overcome to an extent with the use of an endoscope. Surgery by the nasal route is minimally invasive and is highly advantageous for patients. In this study, we summarize and report the current problems associated with optic nerve decompression.
