To correlate computed tomography findings and endoscopic localisation of the anterior ethmoidal artery during surgery, and to analyse the intranasal landmarks and abnormalities of the artery.
The anterior ethmoidal artery was studied with high-resolution computed tomography and endoscopic surgery in 30 patients undergoing functional endoscopic sinus surgery (group A), and with endoscopic dissection on 30 human cadavers (group B).
The anterior ethmoidal artery was demonstrated on computed tomography in 25 patients and intra-operatively in 12 (group A). It was identified in 26 cadavers (group B). Dehiscence of bony canal and branching was noted in 10.53 per cent of cases. The mean (± standard deviation) intranasal length of the anterior ethmoidal artery was 7.29 (± 1.21) mm, the distance of the artery from the axilla of the middle turbinate was 16.24 (± 2.75) mm, and the mean distance from the ground lamella was 8.97 (± 1.46) mm.
High-resolution computed tomography scanning prior to functional endoscopic sinus surgery is mandatory to identify the anterior ethmoidal artery. Endoscopically, the axilla of the middle turbinate and the ground lamella can serve as dependable reference points to identify the artery. Cadaver dissection improves understanding of anatomy.
在手术中对额前动脉的计算机断层扫描结果与内镜定位进行相关性分析，并分析其鼻腔内的标志和动脉异常。
对 30 例行功能性内镜鼻窦手术的患者（A 组）进行高分辨率计算机断层扫描和内镜手术，对 30 例人体尸体（B 组）进行内镜解剖，研究额前动脉。
在 25 例患者的计算机断层扫描中显示出了额前动脉，在 12 例患者的手术中发现了（A 组）。在 26 具尸体中识别出了额前动脉（B 组）。10.53%的病例存在骨管缺损和分支。额前动脉的鼻腔内平均长度为 7.29 ± 1.21mm，距中鼻甲腋部的距离为 16.24 ± 2.75mm，距底隔的平均距离为 8.97 ± 1.46mm。
在进行功能性内镜鼻窦手术前，必须进行高分辨率计算机断层扫描以识别额前动脉。在镜下，中鼻甲腋部和底隔可以作为识别动脉的可靠参考点。尸体解剖有助于加深对解剖结构的理解。
