Table 2: Our protocol for the treatment of trigeminal neuralgia based on age of the patients and interested trigeminal division. The first, the second or even the third suggested therapeutic options are indicated in each patient. MVD = microvascular decompression in posterior cranial fossa TN= Trigeminal Neuralgia
