To study different types of extension of sphenoid sinus pneumatization detected by CT and examine their correlation with other anatomical variants.
Sphenoid sinus pneumatization was characterized (780 hemi-sinuses) on CT scans. Its incidence and correlations with related anatomical variants were evaluated. Dimensions of surgical window were measured in the lateral type, where pneumatization extends beyond a line connecting Vidian (pteregoid) canal (VC) and foramen rotundum (FR).
The lateral recess of the sphenoid sinus was pneumatized in 27.3% of patients with a mean width of 7.59 mm. The distance separating the FR and the VC correlated strongly with the depth of the lateral recess. There was significant positive correlation between pneumatization of lateral recess and Vidian nerve prominence to other pneumatization patterns (lesser sphenoid, frontal, and Maxillary sinuses) (p < 0.0001). Lateral recess pneumatization in coronal cuts was also significantly correlated with anterior-posterior sphenoid pneumatization in sagittal cuts (p < 0.0001).
Pre-operative assessment of sphenoid sinus pneumatization is essential in the endoscopic approach to skull base structures to facilitate surgical access and avoid injury of the nearby structures. Our study showed significant correlation among anatomical variants and different measurements which allows the surgeon to predict abnormal anatomy with high accuracy.
研究 CT 检测到的不同类型的蝶窦气化扩展，并探讨其与其他解剖变异的关系。
对 CT 扫描中的蝶窦气化进行特征描述（780 个半鼻窦）。评估其发生率及其与相关解剖变异的关系。在外侧型中测量手术窗的尺寸，其中气化延伸超过连接 Vidian（翼突）管（VC）和圆孔（FR）的线。
27.3%的患者蝶窦外侧隐窝气化，平均宽度为 7.59mm。FR 和 VC 之间的距离与外侧隐窝的深度密切相关。外侧隐窝气化与 Vidian 神经突出与其他气化模式（较小的蝶窦、额窦和上颌窦）之间存在显著正相关（p<0.0001）。冠状位的外侧隐窝气化与矢状位的前后蝶窦气化也有显著相关性（p<0.0001）。
在经内镜颅底结构手术中，术前评估蝶窦气化对于手术入路的选择和避免邻近结构损伤至关重要。我们的研究表明，解剖变异之间存在显著相关性，且不同测量之间具有高度相关性，这使得外科医生能够以高精度预测异常解剖结构。
