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. Neuropathic pain is the cardinal sign of injury to the small unmyelinated and thinly myelinated primary afferent fibers that subserve nociception. The pain mechanisms themselves are altered. Microanatomic small and large fiber damage in the nerve, essentially demyelination, commonly observed at its root entry zone (REZ), leads to ephaptic transmission, in which action potentials jump from one fiber to another.A lack of inhibitory inputs from large myelinated nerve fibers plays a role. Additionally, a reentry mechanism causes an amplification of sensory inputs. Simpler, less invasive procedures are well tolerated but usually provide only short-term relief. At this point, further and perhaps more invasive operations may be required, and with these procedures the risk of the disabling adverse effect of anesthesia dolorosa increases. Poland people around 1,124,189 among the total population are suffering from this disease that is 4.98% of the population effected.
