Abstract: To build a digitized visible model of nasal anatomical structures. MethodsData of the cross-sectional image range of the first set of Chinese visible human female database(CVH-2) from the top layer of the frontal sinus to the bottom layer of the maxillary sinus were used in this study. The contour of organs was segmented from the cross-sectional images and 3D reconstructed by the Amira 4.1 and Radio- Dexter software in a computer. ResultWe successfully reconstructed 3D visible models of the main nostril structures, such as the nasal bone， frontal sinus， ethmoidal sinus， sphenoidal sinus， maxillary sinus， nasal cavity， superior, middle or inferior nasal turbinate， crista galli， nasal septum， uncinate process， nasolacrimal canal， internal carotid artery， and optic nerve. These models could be displayed from any directions, and the spatial positions and adjacent relationships of different anatomical structures， also the reconstructed structures could be determined in 3D space. ConclusionThese visible nasal models have facilitated observing and understanding of the anatomical structures in this area, provide the morphological data for imaging diagnosis of nasal diseases and nasal endoscopic surgeries, and also could be used in virtual surgeries.
