Trigeminal neuralgia is commonly known as the “number one pain in the world” and is mostly seen in the elderly. The pain is like a lightning bolt that strikes the jaw and face, yet more than half of the patients have been misdiagnosed as toothache. Without proper treatment, the pain will only get worse and worse, and rarely gets better naturally, and the pain becomes unbearable for people, and patients often feel worse than death when it develops. The first choice of treatment is drugs, commonly used carbamazepine, but the side effects are large; open microvascular decompression is commonly used for trigeminal neuralgia treatment, but there are certain risks; percutaneous puncture microballoon compression trigeminal ganglion technique for trigeminal neuralgia has small risk, high success rate, few and mild complications, simple and easy to perform, short hospitalization time, low cost and less patient pain. It is especially suitable for elderly patients and has been used for 30 years. It has proven to be a very effective and safe surgical treatment for trigeminal neuralgia.
