三叉神经的上颌神经痛发病率较高 ,迄今为止 ,神经阻滞疗法仍是治疗三叉神经痛最有效的方法 ,它还具备经济、简单等优点[1] 。由于上颌神经从颅腔至面部途径翼腭窝等处 ,行程复杂。为上颌神经阻滞入路提供形态学依据 ,本文对 12 0侧成人颅骨翼腭窝等结构和 30侧成人头部标本的 The incidence of maxillary neuralgia in the trigeminal nerve is high. So far, the nerve block therapy is still the most effective method for the treatment of trigeminal neuralgia. It also has the advantages of economy and simplicity [1]. As the maxillary nerve from the cranial cavity to the facial pathway pterygopalatine fossa and other places, the trip complex. To provide a morphological basis for the approach of maxillary block, in this paper, 120 adult skull pterygopalatine fossa and other structures and 30 adult head specimens
