Current clinical research proves that no matter which method is used for trigeminal neuralgia, there is a recurrence rate of 5% to 20% about two years after surgery. Trigeminal neuralgia is so difficult to cure and easy to recur, the pain and suffering for trigeminal neuralgia patients and the whole family can be imagined. Trigeminal neuralgia is stubborn and its cause is unknown. The reason for its recurrence is inseparable from the following reasons. [Factors leading to the recurrence of trigeminal neuralgia] 1. abnormal excitatory discharge of the nucleus of the trigeminal nerve bundle and sensory nucleus of the brainstem; 2. damage to the thalamus, which is one of the causes of the recurrence of trigeminal neuralgia; 3. demyelination of the sensory root of the trigeminal nerve or the semilunar ganglion or the peripheral branches of the trigeminal nerve by compression or damage, such as abnormal anatomical structures, vascular malformation, inflammation of the periosteum of the bone foramen, arteriosclerosis, etc.; 4. maxillary and mandibular Pathological bone cavity, although the etiology is multifaceted, ultimately leads to abnormal cranial brain cell discharge, the appearance of trigeminal brain stem cell evoked potentials, and painful episodes. The evoked potentials are generated by slight stimulation and can even be spontaneous, so trigeminal neuralgia is often recurrent and difficult to cure; 5. This is the most common factor that induces the recurrence of trigeminal neuralgia, that is, bad habits or inattention to life (cold stimulation, touch stimulation, food stimulation) or mood swings. Experts remind: trigeminal neuralgia patients in life to ensure adequate nutrition, but not too greasy, should eat regularly, eat more light food, do not use stimulating food, daily avoid strain, pay attention to keep warm.
