鼻内鼻窦手术常引起手术并发症,严重者如失明、颅内感染等。对1986～1991年间进行筛窦内窥镜显微手术(311例次)的190例病人(平均年龄男45岁,女46岁)进行总结。最常发生并发症的5个高危区分别是:①纸样板,由于其很薄、脆弱且凸出到手术区,在筛窦手术时相对易发生损伤,有两种方法可避免其损伤:术前CT研究确定纸样板中央突出的水平;先识别 Intranasal sinus surgery often cause complications, such as blindness, intracranial infection. A total of 190 patients (mean age, 45 years old, 46 years old, 46 years old) undergoing ethmoidal endoscopic microsurgery (311 cases) between 1986 and 1991 were summarized. The five most common areas where complications are most common are: ① Paper templates, which are relatively easy to damage during ethmoid sinus surgery due to their thinness, fragility and bulging into the surgical area, are prevented in two ways: Pre-CT studies determine the prominence of the center of the paper template; identify first
