许多研究表明,蝶窦气化(SSP)影响包括视神经管(OC)在内的相邻结构的突出/开裂,圆孔(FR),vidian运河(VC),和颈动脉管(CC)。了解这种关系对于确定经蝶窦手术期间最安全的手术途径至关重要。因此,我们旨在根据矢状面和冠状面SSP(SSSP和CSSP)模式确定相邻结构突出/开裂的个体化患病率.分析了300例患者的计算机断层扫描图像,以识别SSSP和CSSP类型。并确定相邻结构的突出/开裂。使用年龄方面的统计分析检查变量之间的关系,性别,和偏侧性。最普遍的SSSP类型是卒后(62.7%),其次是赛尔(30%),赛前(6.6%),和conchal(0.7%)。在71.3%的患者中,观察到五种类型的CSSP,23.6%和21.7%表现为IV型和V型,分别。我们的结果表明,后星型,IV型和V型CSSP与OC突出/开裂的可能性最高相关,FR,VC,CC。此外,这些定性变量与性别之间没有显著的相关性,除了VC开裂,OC和CC的突出。在侧向性方面没有发现明显的差异。此外,具有后星类型的可能性,IV型和V型CSSP,以及OC的突出,VC,CC,随着年龄的增长而减少。需要对这种关联进行进一步的详细分析,以预测手术窗口的大小并防止神经血管损伤。
Many studies revealed that the sphenoid sinus pneumatization (SSP) affects the protrusion/dehiscence of adjacent structures including optic canal (OC), foramen rotundum (FR), vidian canal (VC), and carotid canal (CC). Knowledge of this relationship bears vital importance to identify the safest surgical route during transsphenoidal procedures. Therefore, we aimed to determine the individualized prevalence of the protrusion/dehiscence of adjacent structures based on sagittal and coronal SSP (SSSP and CSSP) patterns. Computed tomography images of 300 patients were analysed to identify the SSSP and CSSP types, and the protrusion/dehiscence of adjacent structures was determined. The relationship between the variables was examined using statistical analysis in terms of age, gender, and laterality. The most prevalent SSSP type was postsellar (62.7%), followed by sellar (30%), presellar (6.6%), and conchal (0.7%). In 71.3% of patients, five types of CSSP were observed, with 23.6% and 21.7% exhibiting Type IV and V, respectively. Our results indicated that postsellar type, Type IV and V CSSP associated with the highest likelihood of protrusion/dehiscence of OC, FR, VC, and CC. Furthermore, no significant correlation was observed between these qualitative variables and gender, with the exception of the VC dehiscence, the protrusion of OC and CC. No notable differences were identified with respect to laterality. Also, the probability of having postsellar type, Type IV and V CSSP, as well as the protrusion of OC, VC, and CC, decreased with increasing age. Further detailed analysis of this association is required to predict the size of the surgical window and to prevent neurovascular injury.
