If you look at what percentage of the population is bound to have Trigeminal Neuralgia, it estimates up to 0.3% of the population. How many new patients have it per year? Maybe less than 0.03% of people will have this per year. If you translate this to the population of Singapore, we are looking at about 800 patients with facial pain per year.
We have no real statistics collected in Singapore for this disease. In terms of pre-deposition, it tends to affect people in their 50s and tends to affect females more than men. I do not think there is a particular reason, it may be due to sensitivity and pain, but no one really knows for sure.
