In the supraobital or pterional keyhole approaches, cavernous sinus tumor can be dissected by removing the anterior clinoid process or cut open the cavernous sinus along the oculomotor nerve. Combining a variety of keyhole approaches is a good way to treat huge tumors spanning the anterior and middle cranial fossa, or those spanning middle and posterior cranial fossa, avoiding the complex operation of a single approach (Level IV recommendation [sup][30],[31]).
Isolated palsy of the oculomotor nerve (cranial nerve III) is seen in association with neoplasms, trauma, infarctions, hemorrhages, demyelination, aneurysms, inflammations, ischemias, infections, and uncal herniations.
The medial aspect of the temporal lobe is forced downward over the tentorium, compressing the neighboring oculomotor nerve and resulting in ipsilateral pupillary dilatation, which is often followed by oculomotor ophthalmoplegia.
The case of a parturient, who first presented with a partial oculomotor nerve palsy shortly after caesarean delivery while participating in a clinical trial, is presented.

If a pupillary response is necessary, a command is transmitted from the brain to the pupil along a separate, oculomotor nerve.
Green dots (efferent pathway) show the projection from the Edinger-Westphal nuclei to the ciliary ganglia via the oculomotor nerve. The ciliary ganglia innervate the sphincter pupillae muscles, resulting in pupillary constriction
