摘　　要：目的:研究筛窦外侧壁显微外科解剖,为临床处理筛窦手术提供解剖学资料。方法:采用显微解剖学技术,对24例成人头颅标本筛窦外侧壁进行观察和测量。结果:Dacryon(泪点,上颌骨、额骨、泪骨的交汇点)至筛前、后孔及视神经管眶口间的距离分别为(21.45±2.54)mm、(34.23±2.90)mm、(39.25±1.53)mm。筛前动脉眶内段长度为(4.98±1.17)mm,筛后动脉眶内段长度为(8.72±2.24)mm。结论:在筛窦手术或视神经管减压术时,Dacryon与筛前孔、筛后孔及视神经管眶口距离,可为正确寻找和处理筛动脉及视神经管提供依据。Objective: To study the microsurgical anatomy of lateral wall of ethmoidal sinus, providing anatomical basis for the operation of ethmoidal sinus. Methods: The lateral wall of the ethmoid was observed and measured in 48 sides of adult cadaveric heads under microscopy. Results:The distances from Dacryon to the anterior and posterior ethmoidal foramen and optic formen were (21.45±2.54)mm, (34.23±2.90)mm, and (39.25±1.53)mm, respectively. The length of intraorbital segment of anterior ethmoidal artery was (4.98±1.17)mm; the length of intraorbital segment of posterior ethmoidal artery was (8.72±2.24)mm. Conclusion: Dacryon is important to locate ethmoidal artery in the operation of ethmoidal sinus and optic canal decompression.
