Agger nasi cells

Agger nasi air cells are the most anterior ethmoidal air cells lying anterolateral and inferior to the frontoethmoidal recess and anterior and above the attachment of the middle turbinate. They are located within the lacrimal bone and therefore have as lateral relations the orbit, the lacrimal sac and the nasolacrimal duct

They are identified in 90% of patients, and should not be confused with Haller cells (located along the medial floor of the orbit) or supraorbital air cells (located in the orbital roof).

The may contribute to chronic frontal sinusitis 3.

History and etymology
