Haller cells are air cells situated beneath the ethmoid bulla along the roof of the maxillary sinus and the most inferior portion of the lamina papyracea, including air cells located within the ethmoid infundibulum. [8] These may arise from the anterior or posterior ethmoidal sinuses. [citation needed]
The ethmoidal labyrinth or lateral mass of the ethmoid bone consists of a number of thin-walled cellular cavities, the ethmoid air cells, arranged in three groups, anterior, middle, and posterior, and interposed between two vertical plates of bone; the lateral plate forms part of the orbit, the medial plate forms part of the nasal cavity.
The ethmoidal infundibulum is bordered medially by the uncinate process of the ethmoid bone, and laterally by the orbital plate of the ethmoid bone. [3] The ethmoid infundibulum leads towards the maxillary hiatus. [2]: 690 The anterior ethmoidal cells open into the anterior part of the infundibulum. [6]

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 frontal recess area, constricting it and causing mechanical obstruction to frontal sinus drainage.
