fa·cial ca·nal

[TA]
the bony passage in the temporal bone through which the facial nerve passes; the facial canal commences at the internal auditory meatus with the horizontal part, which passes at first anteriorly (medial crus of facial canal) then turns posteriorly at the geniculum of the facial canal to pass medial to the tympanic cavity (lateral crus of facial canal); finally, it turns downward (descending part of facial canal) to reach the stylomastoid foramen.
