经鼻入路显露鞍旁结构的三维可视化研究
Three-dimension visualization of transnasal approach for revealing the metasellar organization
摘要
Abstract
Objective To elevate the anatomical cognitive level by investigating the metasellar organization via transnasal approach in a virtual-reality (VR) setting. Methods Twenty-eight patients, with spontaneous subarachnoid hemorrhage but without pathological changes of nasal cavity and sella turcica, underwent the lamellar imaging examination and CT angiogram with Discovery Ultra 16. The data were collected and entered in the Dextroscope in DICOM format. Visualization research was carried out via the transnasal approach in a virtual-reality (VR) setting. Results The anatomic structures of transnasal approach were allowed to be observed dynamically and spatially. When exposing the lateral border of cavernous carotid artery, it was important to excise the ethmoid cornu, open posterior ethmoid sinus and sphenopalatine foramen, control sphenopalatine artery, properly drill out pterygoid process and reveal pterygoid canal. Conclusion It is the key point to remove the ethmoid cornu, uncinate process and bone of the anterior region of sphenoidal sinus, and control sphenopalatine artery via transnasal approach to expose the metasellar structure. The cavernous carotid arteries are the most important anatomic structure, should be adequately exposed and conserved.关键词
