Trigeminal neuralgia: New classification and diagnostic grading for practice and research.

Cruccu G, Finnerup NB, Jensen TS, Scholz J, Sindou M, Svensson P, Treede RD, Zakrzewska JM, Nurmikko T - Neurology (2016)

Bottom Line: Trigeminal neuralgia (TN) is an exemplary condition of neuropathic facial pain.Secondary TN is due to an identifiable underlying neurologic disease.TN of unknown etiology is labeled idiopathic.

Innervation territories of the trigeminal nerveFacial and intraoral territories of innervation of the 3 trigeminal branches (ophthalmic, maxillary, and mandibular). The white areas are innervated by cervical nerves. The light gray areas in the back of tongue and throat are innervated by the glossopharyngeal nerve.

Figure 2: Innervation territories of the trigeminal nerveFacial and intraoral territories of innervation of the 3 trigeminal branches (ophthalmic, maxillary, and mandibular). The white areas are innervated by cervical nerves. The light gray areas in the back of tongue and throat are innervated by the glossopharyngeal nerve.

Mentions: The minimum requirements for possible TN are pain distribution within the facial or intraoral territory of the trigeminal nerve and a paroxysmal character of pain (figure 1). The examining physician must ascertain that the pain does not extend to the posterior third of the scalp, the back of the ear, or the angle of the mandible, as these territories are innervated by cervical nerves (figure 2). The territory of the mandibular division of the trigeminal nerve reaches to the cranium; a patient with TN in the mandibular branch of the trigeminal nerve may therefore describe pain both in the lower lip and the temple. If the neuralgia involves 2 trigeminal divisions, they should be contiguous; a combination of the maxillary and mandibular divisions is most frequent. TN in the ophthalmic division or the tongue tends to be considered an indication of TN secondary to a major neurologic disease. However, this interpretation has not been adequately scrutinized.4,5 It is further important to note that both the affected division of the trigeminal nerve and the side of the face may change over the course of the disease.6–8
