Objective:To design and produce cross-sectional anatomical models of paranasal sinuses for the purpose demonstrating drainage pathways each nasal sinus young doctors. Method:We reconstructed three-dimensional model area based on CT scan data, divided it into 5 thick anatomy by 4 coronal plane，which cross middle points agger nasi cell, ethmoid bulla, posterior sphenoid respectively. Then a 3D printerwas used to make models.Result:Successfully produced digital printing sinuses. Sinus were observed models. Conclusion:The made us can exactly intuitively demonstrate ostia cell they help doctors understand master key anatomies relationships which are important endoscopic surgery.
