用眶下神经切断术不能解除面部疼痛的病例,上颌神经切断术是一个指征。作者报导了一例患有左上颌支三叉神经痛的病人,并介绍了经上颌窦作上颌神经切断术的方法。病人在气管内全麻下做了经上颌窦径路的上颌神经切断术。在上颌前庭处,从上颌结节到中线作一切口,翻开粘膜骨膜瓣,暴露上颌骨前侧面以及颧骨和眶下神经。在上颌窦的前外侧壁上开一个3厘米直径的窗。然后在手术显微镜下进行。仔细地切开上颌窦后上方的粘膜,再去除骨组织,造成一个后窗。去骨后要小心地解剖已暴
Suborbital nerve transection can not relieve the case of facial pain, maxillary nerve transection is an indication. The authors report a case of a patient with trigeminal neuralgia of the left maxillary branch and introduced the method of maxillary nerve dissection via the maxillary sinus. The patient underwent maxillary sinus approach maxillary nerve transection under endotracheal anesthesia. In the maxillary vestibule, from the maxillary nodules to the midline for all incision, open the mucosa flap, expose the anterior maxilla and the zygomatic and infraorbital nerve. Open a 3 cm diameter window in the anterolateral wall of the maxillary sinus. Then under a surgical microscope. Carefully cut the top of the maxillary sinus mucosa, and then remove the bone tissue, resulting in a rear window. Be careful to dissect the bone after bone has been violent
