- Surgical anatomy
- The choroidal fissure is one of the most important landmarks in microneurosurgery involving the body, third ventricle, and temporal lobe. (see anatomical subdivisions)
- Most valuable anatomic landmarks that a neurosurgeon can count on during surgical procedures.
- The choroidal fissure of the temporal horn is easily identified by following the choroid plexus in the medial aspect of the temporal horn;
- All structures located laterally to the choroid plexus belong to the temporal lobe and can be removed, and all structures located medially to the choroidal fissure in the temporal horn belong to the thalamus and should not be harmed.
- Opening the choroidal fissure in the temporal horn leads to the contents of the ambient cistern.
