Trigeminal neuralgia usually does not heal on its own and requires targeted treatment to reduce painful discomfort. The cause of trigeminal neuralgia has not been clearly identified yet. It is characterized by recurrent facial pain, more on the right side than on the left, which starts at a point on the face, mouth or jaw and spreads to one or more branches of the trigeminal nerve, with the second and third branches being the most common, with pins and needles, tearing, burning or electric shock-like pain. Carbamazepine medication is preferred, but carbamazepine does not cure trigeminal neuralgia, but only relieves the symptoms. Trigeminal nerve microvascular decompression surgery is currently recommended to get to the root of the problem and loosen the intracranial vessels compressing the trigeminal nerve. In addition, there are other surgical methods, including radiofrequency thermocoagulation of the trigeminal nerve semilunar ganglion and trigeminal nerve peripheral branch avulsion. Patients with trigeminal neuralgia should pay attention to rest, do not overexert themselves, take physical exercise in moderation to improve body immunity, do not have psychological burdens, make good psychological adjustment, and take medications as prescribed by the doctor.
