The OC is involved in a variety of intracranial and extracranial pathologies,\n 1<\/jats:sup>\n and opening of the canal may be necessary in order to achieve adequate exposure, better disease control, and vision preservation.\n 2<\/jats:sup>\n Depending on the location of the pathology and its relationship with the optic nerve, the OC may be decompressed through an open transcranial approach or an endoscopic endonasal approach.\n 1,3<\/jats:sup>\n OC drilling can be tailored based on the location of the pathology and its extension. Anterior clinoid process and optic strut drilling can be added based on these factors as well.\n 4,5<\/jats:sup>\n <\/jats:p>\n \n In this video, we demonstrate the steps of OC drilling in both transcranial microscopic and endoscopic endonasal approaches through a combination of animated illustrations and operative videos. We present 4 cases, including 2 transcranial microscopic and 2 endoscopic endonasal approaches,\n 6<\/jats:sup>\n demonstrating OC decompression and its technical nuances. Each case was selected to represent the range of pathologies relevant to OC drilling to allow for a complete understanding of the techniques and concepts required for optimal treatment.\n <\/jats:p>\n An informed written consent has been obtained from each of the patients in this publication.<\/jats:p>\n Video \u00a9 Mayo Foundation for Medical Education and Research.
