Temporal Bone Pathology 5: Facial Nerve

Radiology of the Facial and Cochleovestibular Nerves
This video replaces the one with errors in the laser pointer.
This video is equivalent to the lecture on the facial nerve on the Cranial Nerve playlist. You can watch whichever one you happen upon first.

[@sugaplumalex]

is it possible to have a dehiscence between the vestibule and the facial nerve?

For a complete answer to your question, check out this article in the latest AJNR: Razskazovskiy V, et al. Prevalence of Cochlear-Facial and Other Non-Superior Semicircular Canal Third Window Dehiscence on High-Resolution Temporal Bone CT. AJNR 2023 Nov.
But here's a quick answer:
The third-window dehiscenses that have been described in the literature are superior semicircular canal, cochlear-facial nerve canal, cochlear-carotid canal, cochlear-internal auditory canal, superior semicircular canal-superior petrosal sinus, posterior semicircular canal, lateral semicircular canal, and vestibular.
The reason you don't see facial nerve - vestibule on that list is that the facial nerve runs anterior to the IAC and the vestibule is posterior to the IAC.
