As tissue dissections carried out on formaldehyde-fixed anatomical specimens demonstrate, the parasellar region (PSR), traditionally referred to as the cavernous sinus, is composed of three distinct compartments: orbital, pterygopalatine, and lateral sellar. The aim of our study was to identify and measure these compartments in the living and to describe the topography of their adipose body tissues. For this purpose data sets of 35 patients, who had undergone thin-section multislice computed tomography (CT), were examined using 3D-reconstruction software. The pterygopalatine and orbital compartments of the PSR could be identified in the images by their adipose bodies. We provide more exacting measurements of their size than have been presented in earlier studies. Furthermore, we include data about the uni- and bilateral presence of the single compartments and analyze the topography of the adipose tissue bodies in the orbital apex region. Our quantitative data and topographical descriptions confirm the compartmentalization concept of the PSR, allow for correct interpretation of CT scans of the orbital apex and anterior PSR, and provide baseline information for individual planning of surgical and radiological interventions.
正如对甲醛固定的解剖标本进行的组织解剖所显示的那样，传统上称为海绵窦的鞍旁区域（PSR）由三个不同的腔室组成：眶部、翼腭部和鞍旁外侧部。我们研究的目的是在活体中识别和测量这些腔室，并描述其脂肪体组织的局部解剖结构。为此，我们使用三维重建软件对35例接受薄层多层计算机断层扫描（CT）的患者的数据集进行了检查。PSR的翼腭部和眶部腔室可通过其脂肪体在图像中识别出来。我们提供了比早期研究中更精确的尺寸测量数据。此外，我们还纳入了关于单个腔室单侧和双侧存在情况的数据，并分析了眶尖区域脂肪组织体的局部解剖结构。我们的定量数据和局部解剖描述证实了PSR的腔室化概念，有助于正确解读眶尖和前PSR的CT扫描结果，并为手术和放射干预的个体化规划提供基线信息。
