Abstract：
Introduction Functional endoscopic sinus surgery and endoscopic skull base surgery are frequently performed surgeries today. Nasal septal deviation is a common finding and can affect the surgical area. Therefore, it is important to examine the effect of this deviation on other anatomical structures. Objectıve The aim of the present study was to determine whether there is a relationship between the degree of nasal septal deviation and anterior skull base structures using computed tomography (CT). Methods A total of 312 patients (aged 18 to 65 years old) whose paranasal sinus CT images were available were included in the study. Measurements were obtained on images retrieved from Picture Archiving and Communication System (PACS) and Horos image archive systems in the bone window in the coronal and axial plane. Results The mean age of 312 patients was 33.00 years old (standard deviation [SD] 11.22 years). The presence of septal deviation was not associated with changes in olfactory fossa (OF) depths, Keros degrees, and the angle between the lateral lamella and the cribriform lamella. However, OF depths and Keros degrees on the deviated side of the septum were found to change at a significant level ( p < 0.05). No significant association was observed between the degree of septal deviation and cribriform lamella-lateral lamella angle. Conclusion The study showed significantly increased OF depth and Keros degree on the deviated side of the nasal septum. Performing CT scans before endoscopic sinus surgery and endoscopic skull base surgery is important to increase the chances of a successful surgical outcome and to reduce complications.
摘要：
介绍功能性内窥镜鼻窦手术和内窥镜颅底手术是当今经常进行的手术。鼻中隔偏斜是常见的发现，可能会影响手术区域。因此,重要的是检查这种偏差对其他解剖结构的影响。目的本研究的目的是使用计算机断层扫描（CT）确定鼻中隔偏曲的程度与前颅底结构之间是否存在关系。方法选取有鼻旁窦CT图像的312例(年龄18～65岁)患者作为研究对象。在冠状和轴向平面的骨骼窗口中，从图片存档和通信系统（PACS）和Horos图像存档系统检索的图像获得了测量结果。结果312例患者的平均年龄为33.00岁(标准差[SD]11.22岁)。间隔偏离的存在与嗅窝（OF）深度的变化无关，Keros度,以及横向薄片和筛状薄片之间的角度。然而,发现隔膜偏离侧的OF深度和Keros度显著变化(p<0.05)。在间隔偏离程度与筛状薄片-外侧薄片角度之间未观察到显着关联。结论研究显示鼻中隔偏侧的OF深度和Keros度明显增加。在内窥镜鼻窦手术和内窥镜颅底手术之前进行CT扫描对于增加手术成功的机会和减少并发症很重要。
