At the lateral end of the meatus, the facial nerve passes into the facial canal. The nerve then turns sharply posteriorly at the geniculum. The geniculate sensory ganglion is situated here, facial the greater petrosal nerve to the pterygopalatine ganglion arises from this region.
The pensacola escort canal continues posteriorly on the medial wall of the tympanic cavity, facial above the fenestra vestibuli and arching downward and laterally to emerge at the stylomastoid foramen just after giving off the chorda tympani anatomy.
The posterior auricular nerve and the nerves to the stylohoid and posterior digastric muscles arise before the facial nerve nerve the substance of the parotid gland.
