Microvascular decompression for trigeminal neuralgia is usually safer as a surgical procedure. However, any surgery carries certain risks, and it is recommended that the people concerned choose the appropriate treatment according to the condition of the disease after consultation. Trigeminal neuralgia is a kind of recurrent, transient, paroxysmal pain in the distribution area of the trigeminal nerve, which can be categorized into primary trigeminal neuralgia and secondary trigeminal neuralgia according to its causes. When symptoms appear, you should consult a doctor for a clear diagnosis of the disease, and choose the appropriate treatment according to your condition and needs. Trigeminal vascular decompression surgery is the most effective and longest lasting treatment for trigeminal neuralgia, with about 90% of the population experiencing immediate relief of symptoms; however, as a surgical procedure, it carries a certain degree of risk, and requires general anesthesia, and may be more traumatic, so it is suitable for those with good cardiorespiratory fitness who are able to tolerate general anesthesia. There is a possibility of postoperative complications such as facial sensory impairment and low cranial pressure headache after trigeminal nerve microvascular decompression surgery. Patients are advised to choose the appropriate treatment for their condition under the guidance of their doctor.
