我院从七九年四月以来,采用蝶腭神经节切除术治疗三叉神经痛五例。手术方式病员于手术台取斜坡卧位,以柯陆氏手术方式进行局部麻醉。唇内切口需较平素单纯上颌窦手术之切口大一些才便于操作。上颌窦前壁之凿孔也需大些,顶部接近眶下神经孔,下部至上颌窦底线。上颌窦内观察清楚后,即于上颌窦后壁作一大的舌形粘膜瓣,游离缘向上,然后剥离其牯膜瓣至底部、压缩存放一起,用骨凿先由外上方凿开上颌窦后壁,慢慢向下向内暴露出翼腭窝。这样做可减少或避免损伤颌内动脉之机会。骨壁凿开后切开骨膜层、即可达到蝶腭神经节部位。清除局部的脂肪后借助显微镜可以清楚容易地分办出它的节前纤 Five cases of trigeminal neuralgia were treated with sphenopalatine ganglionectomy in our hospital from April 1979. Surgical approach Patient in the operating table to take the supine position to Ke Lu surgery for local anesthesia. Lip incision should be simpler than the simple maxillary sinus incision is easy to operate. Sinus anterior wall of the maxillary sinus also need to be larger, the top of the hole near the infraorbital nerve, lower sinus to the bottom line. Maxillary sinus was observed clearly, that is, in the maxillary sinus wall for a large tongue-shaped mucosal flap, the free edge upward, and then peel the flap flap to the bottom of the compression stored together with the first outside the upper edge of the osteotome to open the maxillary sinus After the wall, slowly down inwardly exposed pterygopalatine fossa. Doing so will reduce or avoid the chance of damaging the internal carotid artery. After the bone wall cut open the periosteal layer, you can reach the sphenopalatine ganglion site. After removing the local fat with the help of a microscope it can be clearly divided into its preganglionic fibers
