This study aimed to assess the sphenoid sinus pneumatization types and their correlation with adjacent neurovascular structures using cone-beam computed tomography (CBCT). This cross-sectional study was conducted on 97 CBCT scans of patients over 18 years of age that were retrieved from the archives of the Oral & Maxillofacial Radiology Department of School of Dentistry. Type of sphenoid sinus pneumatization based on its relationship with sella turcica (conchal, presellar, sellar, and postsellar), the correlation of internal carotid artery (ICA) and optic nerve (ON) with the sinus cavity in the axial and coronal planes (smooth or prolonged type), and presence of Onodi cells and their correlation with the sphenoid sinus (lateral, superior, and superolateral) were all evaluated on CBCT sections. Data were analyzed by the Chi-square and Fisher's exact tests (alpha = 0.05). Postsellar type was the most common sphenoid sinus pneumatization type (82.5%). The Smooth type was the most common form of correlation of ON and ICA with the sphenoid sinus. Onodi cells were noted in 28.9% of the cases; among which, the lateral type had the highest prevalence. Considering the high prevalence of sphenoid sinus pneumatization, Onodi cells, and ON and ICA protrusion in our study population, CBCT should be requested prior to trans-sphenoidal surgical procedures to prevent perioperative and postoperative complications.

本研究旨在使用锥形束计算机断层扫描（CBCT）评估蝶窦气化类型及其与相邻神经血管结构的相关性。本横断面研究对从牙科学院口腔颌面放射科档案中检索出的97例18岁以上患者的CBCT扫描图像进行。基于蝶窦与蝶鞍的关系（鼻甲型、鞍前型、鞍型和鞍后型）评估蝶窦气化类型，在轴位和冠状位平面评估颈内动脉（ICA）和视神经（ON）与窦腔的相关性（平滑型或延长型），以及评估Onodi细胞的存在及其与蝶窦的相关性（外侧、上方和外上方）。在CBCT切片上进行评估。数据采用卡方检验和Fisher精确检验进行分析（α = 0.05）。鞍后型是最常见的蝶窦气化类型（82.5%）。平滑型是ON和ICA与蝶窦相关性的最常见形式。28.9%的病例中发现了Onodi细胞；其中，外侧型的患病率最高。考虑到在我们的研究人群中蝶窦气化、Onodi细胞以及ON和ICA突出的高患病率，在经蝶窦手术前应要求进行CBCT检查，以预防围手术期和术后并发症。
