The trigeminal nerve is a paired cranial nerve that has three major branches: the ophthalmic nerve (V 1), the maxillary nerve (V 2), and the mandibular nerve (V 3). One, two, or all three branches of the nerve may be affected. Trigeminal neuralgia most commonly involves the middle branch (the maxillary nerve or V 2) and lower branch (mandibular ...
Atypical trigeminal neuralgia (ATN), or type 2 trigeminal neuralgia, is a form of trigeminal neuralgia, a disorder of the fifth cranial nerve. This form of nerve pain is difficult to diagnose, as it is rare and the symptoms overlap with several other disorders. [ 1 ]
In neuroanatomy, the trigeminal nerve (lit. triplet nerve), also known as the fifth cranial nerve, cranial nerve V, or simply CN V, is a cranial nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the most complex of the cranial nerves.
ATN pain can be described as heavy, aching, and burning. Affected individuals have a constant migraine-like headache and experience pain in all three trigeminal nerve branches. This includes aching teeth, ear aches, feeling of fullness in sinuses, cheek pain, pain in forehead and temples, jaw pain, pain around eyes, and occasional electric ...
Trigeminal neuropathic pain. Results from unintentional injury to the trigeminal nerve from trauma or surgery. TN4: Trigeminal deafferentation pain. Results from intentional injury to the nerve in an attempt to treat either TN or other related facial pain. TN5: Symptomatic TN. Results from multiple sclerosis TN6: Postherpetic TN.
Contralateral deficits in pain and temperature sensation from body (limbs and torso) Spinal trigeminal nucleus & tract: Ipsilateral deficits in pain and temperature sensation from face Nucleus ambiguus - (which affects vagus nerve and glossopharyngeal nerve) - localizing lesion (all other deficits are present in lateral pontine syndrome as well)
Trigeminal autonomic cephalalgia (TAC) refers to a group of primary headaches that occurs with pain on one side of the head in the trigeminal nerve area and symptoms in autonomic systems on the same side, such as eye watering and redness or drooping eyelids.
This reflex is used to judge the integrity of the upper motor neurons projecting to the trigeminal motor nucleus. Both the sensory and motor aspects of this reflex are through CN V. It is not part of a standard neurological examination. It is performed when there are other signs of damage to the trigeminal nerve.
