For the 5th (trigeminal) nerve, the 3 sensory divisions (ophthalmic, maxillary, mandibular) are evaluated by using a pinprick to test facial sensation and by brushing a wisp of cotton against the lower or lateral cornea to evaluate the corneal reflex. Trigeminal neuralgia may be presented with typical one sided facial pain extending to temple and eye( ophthalmic branch of trigeminal nerve may be involved) and sore gums of the teeth of same side (maxillary branch of 5th nerve). Alcohol, ammonia, and other irritants, which test the nociceptive receptors of the 5th (trigeminal) cranial nerve, are used only when malingering is suspected. There's no specific test for trigeminal neuralgia, so a diagnosis is usually based on your symptoms and description of the pain. can clearly help distinguish between the symptomatic form of trigeminal neuralgia and the idiopathic form of trigeminal neuralgia.
