摘要Purpose of the study: Increasingly, endoscopic nasopharyngeal, extended paranasal sinus and skull base surgery is becoming mainstream. Unlike open surgery where structures of interest are approached from the known and the normal, endoscopic surgery relies on navigation systems or at least a spatial awareness of deeper unseen structures by the surgeon to avoid their damage or encounter. The purpose of this preliminary pilot study was to assess the feasibility of producing a useful 3-D reconstruction of the complex anatomy of the nasopharynx from an ultra-high resolution axial human dataset. Materials and methods: Ultra-high resolution axial slices of 0.01mm intervals of a digital human dataset of the nasopharynx were used for the project. Structures of interest including muscles, vessels, bone and mucosa were outlined using a computer interface. Results: A 3-D model of the human nasopharynx and surrounding structures was reformatted from the digitized slices. Conclusion: A 3-D reconstruction of the nasopharynx with transparency giving visibility to deeper structures and an appreciation of their spatial relationship to each other, and especially to the course of the internal carotid artery, the structure at risk of the greatest consequence of exposure or damage with subsequent rupture and stroke or death, is an essential aid to understanding the complex anatomy of this region.
