对47侧尸头额窦进行观察和测量。结果发现通过位于额隐窝、筛漏斗、上半月裂及上鼻道的窦口直接开口子鼻腔者分别有30（63．8％）、9（19．1％）、3（6．4％）、1（2．1％）侧，通过易额管开口厂额隐窝下筛漏斗上的鼻腔外侧壁者4侧（8．5％）。认为，开口于不同部位的额窦窦四周围结构不同，对研究额窦的生理、病理．以及提高鼻窦内窥镜检查和额窦开放手术具有重要的参考和指导意义。
Forty-seven cadaver heads were observed and measured. The results showed that there were 30 (63.8%), 9 (19.1%), 3 (6.4%) patients directly infiltrating the nasal cavity through the sinus ostium in frontal recess, , 1 (2.1%) side of the nasal cavity through the side of the easy-to-open tube at the infundibulum funnel 4 (8.5%) of the lateral wall. That the opening in different parts of the frontal sinus around the four different structures on the study of the frontal sinus physiology and pathology. As well as to improve the endoscopic sinus surgery and open sinus surgery has important reference and guiding significance.
