摘　　要：目的:应用鼻腔额窦的薄层断面解剖图像,追踪额窦引流通路,测量鼻丘气房、钩突及其他的相关数据,为额窦的鼻丘径路及钩突径路手术提供解剖学依据。方法:通过冰冻铣切技术获得鼻部连续断面图像,不同层面上观察额窦的解剖边界及引流通路,测量鼻丘气房前壁中心与中鼻甲根部前端间距离,气房前壁、钩突水平部根部厚度,与钩突根部连接处的鼻泪管内侧壁的厚度。结果:额隐窝为一复杂的三维空间结构,鼻丘气房前壁中心与中鼻甲根部前端间距离为(7.12±0.74)mm,前壁厚度为(0.47±0.09)mm,钩突水平部根部厚度为(1.27±0.22)mm,与钩突根部连接处的鼻泪管内侧壁的厚度为(1.71±0.08)mm。结论:通过额窦引流通路的薄层解剖,可获得较精确的鼻丘气房前壁及钩突等重要结构的相关数据,为额窦手术提供解剖学指导。Objective： To provide anatomical evidence for frontal sinus surgery through the agger nasi cell approach and the uncinate process approach by using the lamellar sectional anatomy image. Methods： The computerized cryomilling technique was used to obtain the continuous sectional data of the nasal parts. The frontal sinus＇s anatomical boundary and the drainage path were observed. The relationship among the agger nasi cells, the uncinate process and the frontal recess was found. The distance of the center of the agger nasi cell＇s anterior wall to the anterior extremity of the middle nasal concha＇s root, the thickness of the agger nasi cell＇s anterior wall, of the uncinate process＇s root, and of the nasolacrimal canal＇s medial wall connecting with the uncinate process＇s root were, determined. Results： The distance of the center of the agger nasi cell＇s anterior wall to the anterior extremity of the middle nasal concha＇s root was （7.12 ±0.74） mm. The thickness of the agger nasi cell＇s anterior wall was （0.47 ±0.09）mm, of the uncinate process＇s root was （1.27 ± 0.22）mm, and of the nasolacrimal canal＇s medial wall connecting with the uncinate process＇s root was （1.71 ± 0.08） mm. Conclusion： A precise data of the agger nasi cell＇s anterior wall and the uncinate process can be found by the lamellar sectional anatomy image of the frontal sinus.
