上颌窦的病因诊断,自采用鼻和鼻窦内窥镜检术以来已取得了很大进展,目前许多医院已将之列为常规检查项目。本文旨在阐明用内窥镜检查蝶窦的诊断和治疗价值。检查用具为Storz 厂的一组器械,包括:①直径5mm 的粗穿刺针,②0°直视光镜,③70°光镜,③120°倒转光镜,⑤活体组织钳,⑥闪烁发生器和冷光,⑦照相机,⑧光放大器。〔操作技术〕采用沿鼻中隔直达蝶窦的鼻内进路。内窥镜放入鼻腔的方向,与鼻中隔软骨-犁骨连接处所形成之线相平行并在此线上方数毫米处寻找蝶窦前壁,其标志是中鼻甲后端,后鼻
The etiological diagnosis of the maxillary sinus has made great strides since the use of nasal and sinus endoscopy, and many hospitals have now included it as a routine test. This article aims to clarify the diagnosis and treatment of endoscopic sphenoid sinus value. Inspection equipment Storz plant a group of instruments, including: ① diameter of 5mm thick puncture needle, ② 0 ° straight optical microscope, ③ 70 ° light microscope, ③ 120 ° inverted light microscope, ⑤ living tissue forceps, ⑥ flicker generator and cold light, ⑦ camera, ⑧ optical amplifier. [Operation techniques] The use of nasal approach along the nasal septum to the sphenoid sinus. The direction of the endoscope into the nasal cavity, parallel to the line formed by the septum cartilage-vomer junction and looking for the anterior sphenoid wall a few millimeters above this line is indicated by the posterior end of the middle turbinate, the posterior nasal
