Knowledge of the neuroanatomy of the third cranial nerve, oculomotor nerve, which provides motor innervation to four of the six extraocular muscles and the levator palpebrae superioris, and parasympathetic innervation to the sphincter pupillae and ciliary muscles, is critical for neurosurgical management of lesions located in the cavernous sinus or orbit. The oculomotor nerve itself has a complex anatomy regarding anatomical landmarks for its localization, considering the characteristics of the arachnoidal sleeve and cisterns that accompany the oculomotor nerve especially through the cavernous sinus. The aim of this review was to underline anatomical landmarks for localization of the ocumolotor nerve.
