What is the name of the anterior ethmoid air cells found above the middle turbinate?

The anterior ethmoid air cells located above the middle turbinate are referred to as Agger nasi cells. These cells are a common anatomical variant in the paranasal sinuses and are situated in the anterior region of the ethmoid bone, typically above the middle turbinate in the lateral nasal wall. Their recognition is crucial in sinus surgery and for understanding certain sinus-related conditions.

Onodi cells, mentioned in another option, are located posteriorly and laterally to the sphenoid sinus, and they are not the cells in question. Curschmann's spirals are related to asthma and are found in bronchial secretions, while Charcot-Leyden crystals are associated with eosinophilic inflammatory conditions. Therefore, Agger nasi cells specifically align with the anatomical location and classification described in the question.
