Anatomic Considerations in Vestibular Neuritis

Abstract

The bony canal of the superior vestibular nerve is longer than the singular nerve canal. Additionally, the superior vestibular nerve and arteriole travel through a relatively narrower passage than the singular nerve and its vascular supply. From an anatomic standpoint, this renders the superior division of the vestibular nerve more susceptible to entrapment and possible ischemic labyrinthine changes.
