Nose with nasal sinuses, 5-part
English
This 1.5 life-sized model displays the structure of the nose with the nasal sinuses within a right upper face
half.
The color-coded bone allows an external identification of the location of the nasal sinuses by taking a
lateral view through the transparent skin cover. Removing the cheek bone (zygomatic bone) will reveal a
view into the right maxillary sinus. In addition, the right nasal sinus, which is lined with mucosa, has been
opened by a midline incision and its nasal conchae can be removed. The mucous membranes have been
partially excised to reveal the olfactory nerves, the nerve supply of the lateral sinus wall, the nasal conchae
and the roof of mouth.
