Dr. Sowmya Hemantha Kumar* and Dr. K Saraswathi Gopal

ABSTRACT

Trigeminal neuralgia (TN) is a debilitating disorder that presents with a sudden onset of severe, unilateral, paroxysmal, and lancinating pain in one or more of the distributions of the trigeminal nerve. Trigeminal neuralgia affects the trigeminal nerve, fifth most developed and extensive cranial nerve, with a broad distribution territory. Its name - “trigeminal” - is derived from the fact that each nerve, one on each side of the pons, has three major branches: the ophthalmic nerve (V1), the maxillary nerve (V2) and the mandibular nerve (V3). The ophthalmic and maxillary nerves are purely sensory. The mandibular nerve has both sensory and motor functions.[1] It is a mixed nerve conducting sensitive and motor somatic fibers to the face, and is ideally responsible for all its sensitive innervation (touch, pain, temperature and propioception) together with the motor innervation of the mastication apparatus. Though it has been known by various names in the literature such as tic douloureux, trifacial neuralgia, fothergill’s disease (named after john fothergill), the currently accepted terminology is trigeminal neuralgia.[2]
