Trigeminal neuralgia (TN), also called tic douloureux, is a chronic pain condition that affects the trigeminal or 5th cranial nerve, one of the most widely distributed nerves in the head. TN is a form of neuropathic pain (pain associated with nerve injury or nerve lesion.) The typical or "classic" form of the disorder (called "Type 1" or TN1) causes extreme, sporadic, sudden burning or shock-like facial pain that lasts anywhere from a few seconds to as long as two minutes per episode. These attacks can occur in quick succession, in volleys lasting as long as two hours. A puzzling fact in TGN is that very different treatments yield seemingly similar results in controlling TGN pain. However, closer inspection of the longâterm effects suggests that simple blocks or minimally destructive peripheral procedures lead to transient pain relief, much shorter than seen in more proximal lesions or decompression. 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. Singapore people around 52,153 among the total population are suffering from this disease that is 1.48% of the population effected.
