3D Printed Sinus Pathways

3D Printed Sinus Pathways This 3D model provides a midsagittal to parasagittal segment of a right head to demonstrate the relationships and passageways of the paranasal sinuses. These passageways have been highlighted with thin coloured markers to indicate the relationship of these communicating routes between the paranasal sinuses and the nasal cavity. Starting anteriorly in the nasal cavity, the opening of the nasolacrimal duct (white) is present just deep to the inferior nasal conchae. The middle nasal concha has been sectioned to allow for a clear view of the opening of the maxillary sinus (visible in the parasagittal plane) across the semilunar hiatus (green), as well as the drainage of the frontal sinus (blue; with the sinus visible superiorly in the section and in the transverse cut through the specimen) and the anterior (orange) and middle (yellow) ethmoidal cells. The opening of the posterior ethmoidal cells into the superior meatus is sho
