Anatomical terms of bone |
Between the styloid and mastoid processes of the temporal bone is the stylomastoid foramen
It is the termination of the facial canal, and transmits the facial nerve and stylomastoid artery.

Clinical Relevance
Bell's palsy can result from inflammation of the facial nerve where it leaves the skull at the stylomastoid foramen. Patients with Bell's palsy appear with facial drooping on the affected side.

- The goal of this surgical protocol is to expose the facial nerve, which innervates the facial musculature, at its exit from the stylomastoid foramen and either cut or crush it to induce peripheral nerve injury. Advantages of this surgery are its simplicity, high reproducibility, and the lack of effe
