Ethmoidal air cells
Updates to Article Attributes
The ethmoidal sinuses (or ethmoidal air air cells) are one of the four paranasal sinuses sinuses. They are located within the ethmoid bone bone. They are present at birth and they develop rapidly from 0-to-4 year-old; they further mature from 8-to-12 year-old during puberty.
Gross anatomy
A collection of air cells (3-18 in number) divided by bony septa within the lateral mass, or labyrinth, of the ethmoid bone.
Separated into anterior and posterior groups by the basal lamella, the lateral attachment of the middle turbinate to the lamina papyracea.
The anterior ethmoidal air cells drain to the hiatus semilunaris and middle meatus via the ethmoidal bulla, which form parts of the ostiomeatal complex. The posterior ethmoidal air cells drain to the superior meatus and sphenoethmoidal recess2.
Some of the ethmoidal air air cells have their own name, because of their importance in surgical procedures or their involvement in head and neck pathologies:
