The agger nasi (from Latin: agger meaning "mound or heap") is a small ridge on the lateral side of the nasal cavity. It is located midway at the anterior edge of the middle nasal concha, directly above the . It is formed by a mucous membrane that is covering the of the maxilla.
It is also called the nasoturbinal concha and the nasal ridge. In 90% of patients an anterior ethmoidal cell (called the "agger nasi cell") can be found in the lacrimal bone below the agger nasi ridge.[1] An enlarged agger nasi cell may encroach the area, constricting it and causing mechanical obstruction to frontal sinus drainage.
