- Agger nasi cell
Agger nasi air cells are the most anterior ethmoidal air cells lying anterolateral and inferior to the frontal 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 4. Agger nasi cells lie anterior to the ethmoidal bullae and may narrow the nasofrontal recess, causing frontal sinus disease 5.
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).
They may contribute to chronic frontal sinusitis 3.
History and etymology
From the Latin "agger nasi", literally meaning nasal mound.
