作者复习了有关资料后指出:因炎症或解剖变异而妨碍鼻中道前端及前、中组筛窦通气时,会损害鼻纤毛清洁功能,使炎症持续不愈或影响额窦和上颌窦的引流,并可能导致鼻窦炎症的反复发作。因此,及早地诊断、治疗筛窦炎症,对提高鼻窦炎的疗效有重要意义。但常规前鼻镜检查及X线摄片、常不能显示前组筛窦和鼻中道前端的病变,鼻内窥镜及鼻、鼻窦CT检查,能帮助诊断。作者对鼻内窥镜的器械和操作方法作了介绍。器械:检查鼻腔时,常选用视角为30°或70°,直径为2.7mm或4.0mm的Hopkins窥镜;检查
After reviewing the data, the authors pointed out: due to inflammation or anatomical variation and hinder the nasal passage and the anterior ethmoid sinus ventilation, it will damage the nasal ciliary cleaning function, the inflammation continued unhealed or affect the frontal and maxillary sinus drainage , And may lead to recurrent sinusitis. Therefore, the early diagnosis and treatment of ethmoid sinus inflammation, improve the efficacy of sinusitis is of great significance. However, conventional anterior rhinoscopy and radiography, often can not display the anterior ethmoid sinus and nasal pathological lesions, nasal endoscopy and nasal sinus CT examination can help diagnose. The author describes the instruments and operating methods of nasal endoscope. Instruments: check the nasal cavity, often choose the view angle of 30 ° or 70 °, diameter 2.7mm or 4.0mm Hopkins speculum; check
