三叉神经痛是发生在头部最粗大的神经之一三叉神经的一种慢性疼痛。其特征是剧烈、间断发作、触电样锐痛、刀割样疼痛、突然的烧灼般面部疼痛,每次发作持续时间数秒至2分钟不等,而后迅速缓解。如50%以上的疼痛发作表现为突然发作、间断出现、刀割样或触电感锐痛,可伴有烧灼感,则为三叉神经痛I型;如50%以上的疼痛表现为持续的酸痛或烧灼感,则为三叉神经痛II型。是什么导致的三叉神经痛?一般认为三叉神经痛多为三叉神经出脑干部位受到血管压迫所致,其压迫可导致神经的保护性外衣即髓鞘受到磨损。三叉神 Trigeminal neuralgia is a chronic pain that occurs in the trigeminal nerve, one of the coarsest nerves in the head. It is characterized by severe, intermittent episodes, sharp electric shocks, knife-like pain, sudden burning of facial pain, duration of each episode ranging from a few seconds to 2 minutes, and then quickly relieved. Such as more than 50% of the episodes of pain manifested as sudden onset, intermittent, knife-like or electric shock sharp pain, may be associated with burning sensation, then type I trigeminal neuralgia; such as more than 50% of the pain manifested as persistent pain or Burning sensation, then trigeminal neuralgia type II. What is the cause of trigeminal neuralgia? It is generally believed that the trigeminal neuralgia is mostly due to vascular compression of the trigeminal nerve by the oppression of the nerves, the protective sheath that myelin is worn.
