通过１６侧尸头解剖对上颌窦自然孔位置及与其邻近组织的毗邻关系进行了观察，发现上颌窦口存在着严重的变异，上颌窦口在鼻腔的开口位置多在漏斗内，其上方便是眶内侧壁。上颌窦内口与上颌窦前壁的平均距离为１．１ｃｍ，表明与鼻泪管很近。Ｘ线摄片显示了上颌窦鼻通道与眶壁的密切关系。对７０侧中鼻道上颌窦开窗术中的情况进行了总结和分析，认为鼻科医师应熟知上颌窦鼻通道的解剖特点，进行中鼻道上颌窦开窗时应高度警惕勿损伤眶壁和鼻泪管。
Through the 16 cadaver anatomy on the maxillary sinus natural hole location and the adjacent tissue adjacent relationship was observed and found that there is a serious variation of the maxillary ostium, maxillary sinus ostium in the mouth of the opening position more in the funnel, the above is Orbital wall. The average distance between the maxillary sinus and the maxillary anterior wall was 1.1 cm, indicating close proximity to the nasolacrimal duct. X-ray showed the maxillary sinus nasal passages and orbital wall closely. On the 70 side of the maxillary sinus surgery in the window of the situation were summarized and analyzed that the nasal surgeon should be familiar with the anatomical characteristics of the maxillary sinus nasal passages, the middle of the maxillary sinus should be highly cautioned when not to damage the orbital wall And nasolacrimal duct.
