翼腭凹是一狭窄的骨性间隙。神经血管组织层次重叠,与颌面部疾病诊断和治疗密切相关。1979年我们在反复对国人解剖实验的基础上,藉助手术显微镜,从口腔内经上颌窦“双层”开窗,进入翼腭凹,为顽固性右三叉神经上颌支痛的60岁女性患者,在园孔前行上颌支切断术。达其分布区完全无痛而分析功能正常的良好效果。随访五年未复发,将初步体会报告如下:病史摘要:患者黄某,女,60岁、农民,住院号:254903。右面部阵发性闪电样疼痛五年。曾以药物及两次酒精封闭治疗,只能短期缓解,影响生活和生产。入院时体检:触摸右侧眶下,上唇、鼻尖、鼻翼、牙龈及腭部均可激发闪电样锐痛。全身除心脏有偶发性早搏外,未发现与本病及接受手术有关的病史及病变。诊断:顽固性右上颌支神经痛。本人 Pterygopalatum is a narrow bony gap. Neurovascular tissue layers overlap, and the diagnosis and treatment of maxillofacial diseases are closely related. In 1979 we repeatedly on the basis of anatomical experiments on the basis of the use of surgical microscope, from the oral cavity through the maxillary sinus “double” window, into the pterygophorin, refractory right trigeminal maxillary pain in 60-year-old female patients, at Park hole before the maxillary branch cut off surgery. Its distribution is completely painless and analysis of the normal function of the good results. Follow-up five years without recurrence, the initial experience report is as follows: History Abstract: Patient Huang, female, 60 years old, farmer, hospital number: 254903. Right facial paroxysmal lightning-like pain for five years. Once treated with drugs and two alcohol closed, only short-term relief, affecting life and production. Physical examination on admission: touch the right infraorbital, upper lip, nose, nose, gums and palate can trigger lightning sharp pain. In addition to the heart of the body with occasional premature beats, did not find the disease and surgery-related history and lesions. Diagnosis: refractory right maxillary nerve pain. I
