Trigeminal neuralgia is a disease with a clear etiology, and vascular compression in the trigeminal nerve into the pontine brain region is where the majority of the etiology lies. At present, microvascular decompression is the first choice for trigeminal neuralgia treatment at home and abroad. Microvascular decompression is a minimally invasive surgery, and the procedure can be broadcast live on TV (being able to broadcast live means that the procedure is not bloody and basically risk-free). The vast majority of procedures are highly effective, with no more pain once awake from anesthesia, no further medication required, and no residual neurological impairment. All other treatments are not etiologic and have the potential for neurological impairment in addition to recurrence.
