The endonasal transsphenoidal approach is a fundamental technique for the resection of pituitary tumors. Anatomical variability of the sphenoid sinus and its relationship with neurovascular structures can influence surgical planning and outcomes.
A retrospective observational prevalence study was conducted using data from 102 patients from the INVIMEDIC database. Preoperative tomographic images in DICOM format were analyzed using RadiAnt Viewer. Data were collected in Microsoft Excel and analyzed with the Statistical Package for the Social Sciences 28 for Windows, including cross tables, Pearson's Chi-square test, and logistic regression analysis.
Significant sex-based differences were identified in sphenoid sinus morphology. The mean anteroposterior length in the overall population was 24.55 mm, with males showing greater depth (26.01 mm vs. 22.98 mm in females) and width (33.26 mm vs. 29.94 mm in females).
Significant morphological differences in the sphenoid sinus were observed between sexes, highlighting dimensions that contrast with previous studies. These findings emphasize the importance of assessing anatomical variations to optimize transsphenoidal approach planning and minimize surgical risks.
经鼻蝶窦入路是垂体瘤切除的基本技术。蝶窦的解剖变异及其与神经血管结构的关系会影响手术规划和结果。
使用来自INVIMEDIC数据库的102例患者的数据进行回顾性观察患病率研究。使用RadiAnt Viewer分析DICOM格式的术前断层图像。数据收集在Microsoft Excel中,并使用适用于Windows的社会科学统计软件包28进行分析,包括交叉表、Pearson卡方检验和逻辑回归分析。
在蝶窦形态上发现了显著的性别差异。总体人群的平均前后长度为24.55毫米,男性的深度更大(26.01毫米对女性的22.98毫米),宽度也更大(33.26毫米对女性的29.94毫米)。
观察到蝶窦在性别之间存在显著的形态差异,突出了与先前研究不同的维度。这些发现强调了评估解剖变异以优化经蝶窦入路规划并最小化手术风险的重要性。
