[Applied anatomy for the radiologic and computed tomography study of the paranasal sinuses]

The current diagnosis by images has a significant importance in the medical and/or surgical treatment of the sinusal incidences due to its great sensibility to detect local pathological signs, their limits and neighboring relations. These data are of unvaluable importance at the moment of a therapeutical decision and should be based upon common interests among otorrhinolaringologists and neuroradiologists, speaking the common language given by a firm and shared knowledge of regional anatomy. This presentation is based on the comparison between drawings which show the essential anatomical data and the computed tomography findings, supplying the necessary technical data to obtain veracious images which coincide with the surgeons' angle of view in the direct as well as in the endoscopic approach.
