Optic Canal Decompression: Concepts and Techniques: 2-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2021 Apr 30. Epub 2021 Apr 30.

Department of Neurological Surgery, Mayo Clinic, Phoenix, Arizona, USA.

The optic canal (OC) is a bony channel that transmits the optic nerve (ON) and ophthalmic artery (OphA) as they course through the lesser wing of the sphenoid bone to the orbital apex. The OC is involved in a variety of intracranial and extracranial pathologies,1 and opening of the canal may be necessary in order to achieve adequate exposure, better disease control, and vision preservation.2 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.
