Trigeminus neuralgia treated with Gamma Knife surgery
Trigeminus neuralgia is difficult to treat. For those patients were medication such as carbamazepin is not helpful, the neurosurgeon can treat with the so called Gamma Knife....
A good treatment outcome after such an operation is achieved in more than half of all patients.
Thirty–six percent of patients reported some degree of posttreatment facial numbness.
This study showed that > 50% of patients can be expected to have a good outcome, with ~ 33% having an ideal outcome (pain free with no need for medications).
