To examine the three-dimensional virtual anatomical features of the sphenoid sinus and adjacent structures during virtual surgery and explore their relevance to actual transsphenoidal surgery.
CT images of the sphenoid sinus and surrounding structures from 28 Chinese adult patients were measured using a 16-slice helical CT scanner. Image analysis was performed using the volume-rendering method. Two experienced neurosurgeons wearing stereoscopic glasses performed virtual transsphenoidal surgery by the transnasal approach.
The virtual anatomical features of the sphenoid sinus and the adjacent structures during virtual surgery were described. The distance from the sphenopalatine foramen to the left and right sphenoid ostium was 10.1 ± 2.7 mm and 10.5 ± 3.2 mm, respectively, to the left and right sphenoidal crest 12.9 ± 2.0 mm and 12.8 ± 2.2 mm, respectively, and to the left and right uncinate process 24.0 ± 1.9 mm and 23.9 ± 2.0 mm, respectively. The distance from the uncinate process to the medial and lateral edge of the most prominent part of the anterior bend of the cavernous internal carotid artery (ICA) was 33.7 ± 3.7 mm and 34.8 ± 3.7 mm, respectively, and the angle between the two lines was 9.7 ± 1.9°.
The study provides virtual anatomical information about the sphenoid sinus and important surrounding structures that is essential for successful real life transsphenoidal surgery.
探讨虚拟手术中蝶窦及其毗邻结构的三维立体解剖学特征，并探讨其与经蝶窦手术的相关性。
采用 16 层螺旋 CT 对 28 例中国成年患者的蝶窦及周围结构进行 CT 扫描，应用容积再现技术进行图像分析。两名经验丰富的神经外科医生通过经鼻入路佩戴立体眼镜进行虚拟经蝶窦手术。
描述了虚拟经蝶窦手术中蝶窦及其毗邻结构的解剖学特征。蝶腭孔到左右蝶窦口的距离分别为 10.1 ± 2.7mm 和 10.5 ± 3.2mm，到左右蝶骨嵴的距离分别为 12.9 ± 2.0mm 和 12.8 ± 2.2mm，到左右钩突的距离分别为 24.0 ± 1.9mm 和 23.9 ± 2.0mm。钩突到颈内动脉（ICA）前曲最凸部内、外侧缘的距离分别为 33.7 ± 3.7mm 和 34.8 ± 3.7mm，两条线之间的夹角为 9.7 ± 1.9°。
本研究为成功进行真实经蝶窦手术提供了蝶窦及其重要毗邻结构的虚拟解剖学信息。
