RESUMEN
OBJECTIVE@#To investigate the features of nasal septum cellule in computed tomographic (CT) images and its clinical significance.@*METHOD@#CT scans data of nasal septum in 173 patients were randomly obtained from January 2001 to June 2005. Prevalence and clinical features were summarized in the data of 19 patients with nasal septum cellule retrospectively.@*RESULT@#(1) Nineteen cases with nasal septum cellule were found in 173 patients. (2) All nasal septum cellule of 19 cases located in perpendicular plate of the ethmoid bone, in which 8 cases located in upper part of nasal septum and 11 located in middle.
