The most common medical treatments for TN include either prescription medications or surgery. Typical drugs used to treat this disorder are anti-seizure drugs, such as Tegretol® or Neurontin®. In recent years, different drugs such as Trileptal®, Topamax®, Depakote® and even anti-depressants have been prescribed for TN. However, over a period of time, the drugs’ effectiveness may diminish or serious side effects may develop.
As a last resort, many TN patients consider surgery to end their suffering. According to the Mayo Clinic, the goal of most surgical procedures is to either damage or destroy the part of the trigeminal nerve that is the source of the pain. Because the success of these procedures depends on damaging the nerve, one obvious side effect is facial numbness. Some of the more common surgical procedures include:
- Radiofrequency Rhizotomy
- Glycerol Rhizotomy
- Balloon Compression
- Microvascular Decompression
- Gamma Knife
A recent medical report revealed a 50% failure rate for the treatment of trigeminal neuralgia.
