3D Printed Paranasal Sinus ModelThis unique model has been created from CT imaging and segmentation of the internal spaces of the viscerocranium. Parts of the skull have been retained but sections or windows have been removed to expose the paranasal sinuses. The paired frontal sinuses, with the right being partially subdivided, are coloured blue. The left frontal sinus is largely surrounded by frontal bone, while the right is completely exposed and shows the frontonasal ostium which drain as a funnel shaped tube into the infundibuklum of the middle meatus of the nasal cavity. The ethmoid sinuses or air cells, coloured purple, are only shown on the left.
The medial wall of the orbit composed of the orbital plate of the ethmoid bone is retained. The maxillary sinus (green) on the left has been partly exposed and partly left within the maxilla. The opening of the maxillary sinus into the lateral wall of the nose is barely discernable as a small green patch in the middle meatus. The left sphenoid sinus (pink) is also displayed, within the opened sphenoid bone.

The models are very detailed and delicate. With normal production machines you cannot realize such details like shown in these models.
The printer used is a color-plastic printer. This is the most suitable printer for these models.
The plastic material is already the best and most suitable material for these prints. (The other option would be a kind of gypsum, but this is way more fragile. You even cannot get them out of the printer without breaking them).The huge advantage of the prints is that they are very realistic as the data is coming from real human specimen. Nothing is shaped or stylized.
The users have to handle these prints with utmost care. They are not made for touching or bending any thin nerves, arteries, vessels etc. The 3D printed models should sit on a table and just rotated at the table.
