The canalis facialis has four segments or parts (Lang J 1992 Klinische Anatomie des Ohres. Springer, Vienna, New York), labyrinthine, tympanic, pyramidal and mastoid.
|
553 |
The space for the geniculum is also known as Fossa geniculata (Lang J 1992 Klinische Anatomie des Ohres. Springer, Vienna, New York).
|
554 |
The chorda tympani passes from the facial canal through the posterior tympanic canaliculus to enter the tympanic cavity, then leaves through the anterior tympanic canaliculus to reach the petrotympanic fissure.
|
592 |
The inferior tympanic canaliculus transmits the tympanic branch of the glossopharyngeal nerve, whereas the posterior and anterior tympanic canaliculi transmit the chorda tympani.
|
7292 |
The clinical term cog refers to a coronally oriented osseous ridge protruding in the middle ear cavity, for which the term processus inferior tegminis was introduced (Lang J 1992 Klinische Anatomie des Ohres. Springer, Wien – New York).
|
7294 |
In ENT Surgery, the Crista verticalis is known as 'Bill's bar' (after William House). It separates the Superior portion of the meatus into an anterior channel for the Facial nerve and a posterior channel for the Superior vestibular nerve.
