The lateral cells have not been characterized yet. Other classifications (Lee and Kuhn, International Frontal Sinus Anatomy Classification) neglect them. The aim of this study is to describe lateral frontoethmoidal cells in rhinosinusitis patients. Method: Analysis of medical records and computed tomography (CT) examinations using multiplanar reconstruction with adjustable planes. The lateral cell extending between the frontal beak and the skull base pushing the frontal sinus drainage pathway medially/anteromedially was identified in 6 patients. These cells could not be classified as anterior, posterior or medial according to existing classifications. Four patients were operated on previously due to sinonasal symptoms. The lateral frontoethmoidal cell is an underestimated anatomical variation that may contribute to the persistence of inflammatory disease and can be easily overlooked preoperatively.
