Microvascular Decompression (MVD) is one of the best and most scientific treatments for intractable trigeminal neuralgia, facial spasm, and glossopharyngeal neuralgia; with the improvement of microscope and microscopic technology, MVD can be said to be the first choice for the treatment of intractable trigeminal neuralgia, facial spasm, and intractable glossopharyngeal neuralgia; the reason for this is that it is for the cause of the disease, a functional surgery, and it will not damage the nerves, blood vessels, and brain tissues. The method is simple: the root of the mastoid behind the ear, 5 – 6cm scalp incision, 1 – 2cm diameter bone window, microscopic separation of the adhesion of the arachnoid membrane, blood vessels, pads to insulate non-absorbable, non-rejection of the fiber cotton, you can achieve a one-time radical treatment, the total effective rate of 96% or more. The above views are for patients’ reference only. “Microvascular decompression surgery has become the standard treatment for trigeminal neuralgia. Its advantage is that it can release the local vascular compression while preserving the integrity of trigeminal sensory conduction, and there will be no loss of facial sensation. Microvascular decompression was first proposed by Prof. Jannatta in 1967, and later Haines et al. conducted a more in-depth anatomical study on the relationship between the trigeminal nerve and microvessels, and found that 92.5% of the cases in which there was a pontine parabrachial microvessel compression of the trigeminal nerve root showed trigeminal neuralgia symptoms. Microvascular decompression preserves the anatomical integrity of the trigeminal nerve and therefore normal neurologic function of the trigeminal nerve is preserved. In some patients, it can also eliminate the hypertensive state caused by vascular compression of the brainstem and achieve the goal of eradicating hypertension. Because microvascular decompression surgery has the advantages of obvious pain relief, non-destructive, less side damage, and very low recurrence rate, it is currently internationally recognized as the safest and most effective method of treating trigeminal neuralgia. Surgical complications Except for patients who cannot tolerate surgery, all other patients with trigeminal neuralgia are suitable for microvascular decompression surgery. The most common surgical complications include hearing loss and facial sensory loss, but with the improvement of microsurgical techniques, the incidence of these complications is very low in large neurosurgical institutions, and most of the cerebral nerve injuries, except for hearing loss (incidence rate of about 1%), are more difficult to recover. The symptoms are mild and most of them can be recovered gradually.
