Facial Nerve Canal

The facial nerve canal is a formation in the human skull through which the facial nerve passes. It is located in the upper part of the face and is responsible for the movement of muscles between the eye, nose, lips and jaw. The facial nerve canal is an important structure of the face that allows mobility and expression of emotions. Its dysfunction can lead to a variety of facial problems, including facial paralysis, loss of sensation, and other disorders.

The facial nerve canal is a round bundle of tissue located in the temporal bone above the wings of the nose and in front of the mamillary part of the frontal bone. Its upper end enters the wedge-shaped cavity, where it branches into two branches: posterior and anterior. The posterior branch runs along the temple to the lower part of the auricle, dividing into five fibers: biostial, supramental, greater cartilaginous nerve, buccal and pterygoid. The anterior branch of the facial nerve lies between the oval process and the vomer and continues along the cheek as the mucous nerve along with the glossopharyngeal plexus and the maxillary branch of the trigeminal nerve.
