Abstract: Currently, computed tomography is the method of choice for assessment of paranasal sinuses, nasal fossae and their anatomical variants. Presumably, these variations might induce osteal obstruction, preventing mucus drainage and predisposing to chronic rhinosinusitis. However, this concept is still controversial and the presence of any anatomical variant does not necessarily establish an etiology for rhinosinusitis. Among three subtypes of concha bullosa, only the bulbous type seems to be strongly associated with symptoms. Size and obliteration of osteomeatal complex drainage pathways may be relevant as well. Variations and tomographic signs of sinusal disease occurring on the same side reinforce the likelihood of interference with the mucus drainage process. Computed tomography offers detailed study of anatomical variations and is an invaluable tool for managing clinical decisions and planning surgical strategies. Imaging assessment must be based on identification of variants, definition of their dimensions, as well as on their association with obstruction of drainage ostia and tomographic signs of sinus disease.
