作者介绍用经典式鼻内筛窦切除术(NF)的经验并提出便于比较手术效果的分类方法。于1974～1984年用改良Yankauer(1921)术式作过1077例NE,其中825次同时蝶窦切除。近15年经典术式并发症明显降低,多采用蝶筛窦同时手术尽可能清除全部病变。蝶窦插管为清理病变打开窦腔和作为手术标志,要处理多窦病变和术前用药物治疗。作者提出基于病变程度和类型、伴否哮喘作为鼻窦疾病的分类方法。病变程度分局灶性(一窦或几窦小范围病 The authors describe the experience with classic intranasal ethmoidectomy (NF) and propose a classification that facilitates the comparison of surgical outcomes. In 1974 to 1984 with modified Yankauer (1921) surgery made 1077 cases of NE, including 825 simultaneous sphenoid resection. Nearly 15 years of classic surgical complications was significantly reduced, and more use of butterfly ethmoid sinus surgery as much as possible to remove all lesions. Sphenoid sinus intubation to clean the lesions open the sinus cavity and as a sign of surgery to deal with multiple sinus lesions and preoperative medication. The authors propose a classification based on the degree and type of disease, with or without asthma as a sinus disease. Focal degree of lesion (a sinus or sinus ailments disease
