The common cause of facial nerve injury is fracture of the rocky bone part of the middle cranial fossa and the mastoid process. The facial nerve is susceptible to traction, contusion, or compression by the fracture fragments, resulting in early or late-onset facial nerve paralysis, with muscle weakness, muscular atrophy, and sensory and sphincter functions that are generally unaffected as the main clinical manifestations.
