Trigeminal nerve sensory rhizotomy is a common treatment for trigeminal neuralgia, which cuts off the trigeminal nerve sensory roots to relieve pain. Trigeminal nerve sensory rhizotomy is a suboccipital approach to cut the trigeminal nerve sensory root at the connection of the cerebellum and pontine brain to solve the trigeminal neuralgia problem from the root, which is mainly suitable for secondary neuralgia, ineffective microvascular decompression surgery and recurrence of neuralgia after the operation. However, the risk of this surgery is relatively high, and it is easy to cause some complications after the operation. It should be noted that before trigeminal nerve sensory rhizotomy, it is recommended to consult a professional doctor in detail, fully understand the indications and contraindications of this surgery, and take precautions in advance to avoid postoperative complications. At the same time, patients should maintain an optimistic attitude towards life, keep their emotions stable, do not get too excited, and develop regular work and rest habits, which can alleviate the symptoms of trigeminal neuralgia.
