“…By the 16th week, the neural connections are completely developed. The bony facial canal develops until birth, enclosing the facial nerve in bone throughout its course except at the facial hiatus (the site of the geniculate ganglion) in the floor of the middle cranial fossa [3, 4]. The only difference between the anatomy of the facial nerve in infants compared with adults is in the region of the stylomastoid foramen.…”

“…It runs posterior-superior to the cochleariform process, superior and lateral to the oval window, and then inferior to the lateral semicircular canal. Bony dehiscence of the facial nerve canal is seen in 41–75% of people within this segment [4, 11, 12]. At the pyramidal process, the tympanic segment turns inferiorly at a 95°–125° angle (at the second genu) to become the mastoid or vertical segment [12].…”

Imaging plays a critical role in the evaluation of a number of facial nerve disorders. The facial nerve has a complex anatomical course; thus, a thorough understanding of the course of the facial nerve is essential to localize the sites of pathology. Facial nerve dysfunction can occur from a variety of causes, which can often be identified on imaging. Computed tomography and magnetic resonance imaging are helpful for identifying bony facial canal and soft tissue abnormalities, respectively. Ultrasound of the facial nerve has been used to predict functional outcomes in patients with Bell's palsy. More recently, diffusion tensor tractography has appeared as a new modality which allows three-dimensional display of facial nerve fibers.
