3B Scientific® Nose and Paranasal Sinus

The 3B nose model is a great teaching tool, with detailed anatomy.

This nose model illustrates the structure of the nose with the paranasal sinuses in the upper right half of a face in 1.5-fold enlargement. The following structures can be seen from the outside of the nose with paranasal sinuses, differentiated by color (also visible through the removable transparent skin):
The outer nasal cartilages
The nasal cavity, maxillary, frontal and ethmoid sinuses
The opened maxillary sinus when the zygomatic arch is removed

The following nose and paranasal sinuses structures are shown in a median section:
The nasal cavity, lined with mucosa, with the nasal conchae (removable)
The arteries of the mucous membrane
The olfactory nerves
The innervation of the lateral wall of the nasal cavity, the nasal conchae and the roof of mouth (palate)
