Trigeminal neuralgia (TN, or TGN), also known as prosopalgia, tic doloureux, or Fothergill's disease is a neuropathic disorder characterized by episodes of intense pain in the face. It has been described as among the most painful conditions known. The pain originates from a variety of different locations on the face and may be felt in front of the ear, eye, lips, nose, scalp, forehead, cheeks, mouth, or jaw and side of the face. Because the exact pathophysiology remains controversial, the etiology of trigeminal neuralgia (TN) may be central, peripheral, or both. The trigeminal nerve (cranial nerve V) can cause pain, because its major function is sensory. Usually, no structural lesion is present (85%), although many investigators agree that vascular compression, typically venous or arterial loops at the trigeminal nerve entry into the pons, is critical to the pathogenesis of the idiopathic variety. This compression results in focal trigeminal nerve demyelination. The etiology is labeled idiopathic by default and is then categorized as classic trigeminal neuralgia. Trigeminal neuralgia is treated on an outpatient basis, unless neurosurgical intervention is required. Management of this condition must be tailored individually, based on the patient's age and general condition. In the case of symptomatic trigeminal neuralgia, adequate treatment is that of its cause, the details of which are out of the scope of this article. Argentina people around 1,17,51,53 among the total population are suffering from this disease that is 3.58% of the population effected.
