(or fifth cranial) nerve arises from the lateral surface of the mid-pons and traverses the middle cranial fossa to Meckel's cave, where the trigeminal ganglion splits into three divisions (ophthalmic, maxillary and mandibular). The trigeminal nerve includes sensory and motor nuclei in the brainstem.

            Note 2: The trigeminal nerve provides sensory innervation to the face, teeth, mouth and nasal cavity, and motor innervation to the facial muscles involved in mastication.

            Note 3: Trigeminal neuralgia is also known as tic douloureux.

         trigeminal neuropathy:
              1.           means continuous or near-continuous facial pain, characterised as burning, squeezing, aching or like pins and needles, that occurs in the distribution of one or more branches of the trigeminal nerve, and/or symptoms or signs of impaired motor, sensory or autonomic functioning in the distribution of the trigeminal nerve; and
              1.            includes:
                      1.             neuropathy confined to the trigeminal nerve;
                      2.           neuropathy of the trigeminal nerve occurring simultaneously with other cranial nerve disorders; and
                      3.         trigeminal sensory neuropathy; and
              2.            excludes:
                      1.              persistent idiopathic facial pain; and
                      2.           trigeminal neuralgia (classical and secondary).

            Note 1: The trigeminal (or fifth cranial) nerve arises from the lateral surface of the mid-pons and traverses the middle cranial fossa to Meckel's cave, where the trigeminal ganglion splits into three divisions (ophthalmic, maxillary and mandibular).

 1.           While trigeminal neuralgia attracts ICD 10 AM code G50.0, in applying this Statement of Principles the meaning of trigeminal neuralgia is that given in subsection (2).
 2.           For subsection (3), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4.
Death from trigeminal neuralgia or trigeminal neuropathy
 1.           For the purposes of this Statement of Principles, trigeminal neuralgia or trigeminal neuropathy, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's trigeminal neuralgia or trigeminal neuropathy.
Note: terminal event is defined in the Schedule 1 – Dictionary.
 1.                Basis for determining the factors
On the sound medical‑scientific evidence available, the Repatriation Medical Authority is of the view that it is more probable than not that trigeminal neuralgia or trigeminal neuropathy and death from trigeminal neuralgia or trigeminal neuropathy can be related to relevant service rendered by veterans or members of the Forces under the VEA, or members
