Computerized tomography (CT) of the skull base region has become an indispensable tool for endoscopic sinonasal surgery.
Fundamental knowledge of the sinus anatomy is crucial for preoperative surgical planning. The aim of this research was to evaluate associations between the anatomical variations sphenoidal sinuses and chronic rhinosinusitis (CRS) by using CT.
A descriptive study was performed on patients with CRS, who were referred to the department of radiodiagnosis and imaging for CT scanning. Parameters were compared between the study and control groups.
Among the anatomical variations, the presence of bilateral accessory septa within the sphenoidal sinus, and dehiscence and protrusion of the internal carotid artery and optic nerve (ON), were high in men and women in the case group compared with the control group. Among the anatomical variations in the sinonasal region of the male participants, a significant association (p < 0.05) was observed with ON protrusion and ON dehiscence. ON protrusion (OR = 2.168) in men was associated with elevated risk of CRS in the study population.
Knowledge of the anatomical variations in the sphenoid sinuses enables better understanding of the limits of surgical dissection during the treatment of sphenoid sinus surgeries.
颅底区域的计算机断层扫描（CT）已成为鼻内镜鼻窦手术不可或缺的工具。
鼻窦解剖学基础知识对于术前手术规划至关重要。本研究的目的是通过CT评估蝶窦解剖变异与慢性鼻-鼻窦炎（CRS）之间的关联。
对因CRS就诊于放射诊断与影像科进行CT扫描的患者进行描述性研究。比较研究组和对照组的参数。
在解剖变异中，与对照组相比，病例组男性和女性蝶窦内双侧副隔的存在以及颈内动脉和视神经（ON）的裂开和突出情况较多。在男性参与者鼻窦区域的解剖变异中，观察到ON突出和ON裂开有显著关联（p < 0.05）。男性的ON突出（OR = 2.168）与研究人群中CRS风险升高相关。
了解蝶窦的解剖变异有助于在蝶窦手术治疗过程中更好地理解手术解剖的限度。
