Trigeminal neuralgia is a type of pain that occurs suddenly and occurs quickly. The pain is often spontaneous or originates from a single point of pain, mostly on one side, there are also some cases of trigeminal neuralgia on both sides but this is rare.

In addition to using drugs to treat trigeminal neuralgia, endoscopic surgery is often chosen to treat this disease. If drug treatment is no longer effective, doctors will consider endoscopic surgery to support the treatment of trigeminal neuralgia.

Any surgical procedure can cause complications during and after surgery. For endoscopic surgery to treat trigeminal neuralgia, the most common complications include: cerebrospinal fluid leakage, bleeding, brain contusion, meningeal bleeding, nerve damage, etc.

The technique of destroying the trigeminal ganglion (Gasser) by injecting absolute alcohol is used in the treatment of trigeminal neuralgia to bring quick results. This method is often applied to patients with poor health, chronic diseases that cannot be operated on or do not agree to surgery.

Lymph node ablation performed under digital subtraction angiography is a minimally invasive, safe, and highly effective technique. Up to 80-90% of patients have complete pain relief after the procedure, the remaining patients still have pain but the level of pain is significantly reduced, no longer affecting their lives much.

Trigeminal neuralgia has many causes, of which tumors in the area where the trigeminal nerve passes or in the surrounding area are also possible causes of trigeminal neuralgia. In addition to typical trigeminal neuralgia, cases caused by tumor compression also have other symptoms caused by the tumor.

In recent years, with the development of medicine and especially the treatment regimen for V-neuralgia resistant to medical treatment that has been used in the past 15 years, including interventional techniques such as: Percutaneous intervention methods (thermocoagulation at the Gasserian ganglion, glycerol injection into the cerebrospinal fluid tank, Gasserian ganglion compression with a balloon), some authors use direct access such as (microsurgical partial resection of main nerve branches, microsurgical decompression of microvascular)

The term primary facial neuralgia describes facial pain that is paroxysmal, episodic, unilateral, and localized to one or more branches of the V nerve. The pathogenesis of this condition remains controversial.
