Abstract

Introduction Diseases of the paranasal sinuses, nasal cavities, and those related to the skull base can be treated with nasal endoscopic surgery. Anatomical references are essential to safely perform these surgeries. Objective  To measure and compare the distance from the posterior wall of the maxillary sinus to the anterior skull base in cadavers and on computed tomography (CT) scans to determine a measurement as an anatomical reference in imaging exams for sinus and anterior skull base surgery. Methods In dissections and CT scans, we took measurements from the most upper and medial point of the posterior wall of the maxillary sinus (point A) to the point where the skull base deflects and the anterior sphenoid wall is formed (Δ 90°; point B), in the right and left nasal cavities. We used 51 cadavers aged ≥ 18 years in the present research. Results  The measurements obtained from CT scans and dissections were greater than 1.5 cm in all cadavers, and they were positively correlated. The 1-cm increase in the AB-tomography measurement corresponded to the 1.08-cm increase to the right and 1.07-cm to the left in the AB-dissection measurement. Conclusion  The CT measurements may be considered a reliable tool to promote safe and effective access to the paranasal sinuses, matching the distance that should be dissected until the anterior base of the skull.

基于 CT 扫描和解剖的解剖测量作为功能性内窥镜鼻窦手术的参考。
引言 副鼻窦、鼻腔以及与颅底有关的疾病可通过鼻内窥镜手术进行治疗。要安全地进行这些手术,解剖学参考资料是必不可少的。目的 测量并比较尸体和计算机断层扫描(CT)中从上颌窦后壁到前颅底的距离,以确定在鼻窦和前颅底手术的成像检查中作为解剖参考的测量值。方法 在解剖和 CT 扫描中,我们测量了左右鼻腔中从上颌窦后壁最上方和最内侧点(A 点)到颅底偏转和蝶骨前壁形成点(Δ 90°;B 点)的位置。本研究使用了 51 具年龄≥ 18 岁的尸体。结果 所有尸体的 CT 扫描和解剖测量值均大于 1.5 厘米,且两者呈正相关。AB造影测量值每增加1厘米,AB解剖测量值就会向右增加1.08厘米,向左增加1.07厘米。结论 CT 测量可被视为促进安全有效进入鼻旁窦的可靠工具,可匹配到颅骨前底部的解剖距离。
