Haller's cell

Haller cell (star) in a CT scan of the paranasal sinuses

A Haller's cell is an additional ethmoid cell ( ethmoidal cell) that can be found in the orbital floor or in the roof of the maxillary sinus. It was first described by Albrecht von Haller , a Swiss anatomist. This is an anatomical standard variant that can be found in 5% to 30% of the population, depending on the literature. Haller's cells are usually found incidentally in a computed tomographic examination of the facial skull. In an unfavorable position, they could hinder the drainage of secretions from the neighboring maxillary sinus. Some studies suggest a greater Haller cysts with sinusitis (for an association sinusitis not), others. In any case, information about this anatomical variant is important when planning a surgical procedure in order to avoid complications.
