What is the ethmoidal labyrinth?
The ethmoidal labyrinth is one of the three parts of the ethmoid bone. It consists of lateral series of tiny air chambers called ethmoid air cells. The ethmoid air cells are fluid-filled thin-walled cavities that are arranged into anterior, middle, and posterior clusters.
What do ethmoidal cells do?
The ethmoidal labyrinth consists of several tiny air-filled cells called ethmoid air cells, which are separated from one air cell to another by thin septa. Collectively, they form an ethmoidal sinus. The function of the ethmoid air cells may be associated with the warming, humidifying, and filtering of inhaled air.

What is the function of maxillary sinus?
The maxillary sinuses might simply serve to improve the respiratory function of the nose. A flow of inspiratory air does not occur. The maxillary sinuses are decisively involved in the production of nitrogen monoxide (NO) and thus in supporting the immune defense of the nasal cavity.
