Abstract: [ABSTRACT]OBJECTIVETo investigate the clinic significance of nasal septal swell body by observing and measuring it in the normal and deviated nasal septum on CT images.METHODSThe locations of the nasal septal swell bodies on horizontal CT images in 50 normal subjects and 30 patients with deviated nasal septum were studied, and their length, width and the thicknesses of the mucosa of the both sides were measured. The data were analyzed with SPSS.RESULTSSeptal swell bodies were observed in most of CT images. The swell body was fusiform and located anterior to the middle turbinate, with mean(SD) width of (10.30±1.27) mm and length of (31.35±5.18) mm. There no marked difference in thickness of the nasal septal swell body between two sides of the nasal septum in normal nasal septum, but the thickness of the nasal septal swell body in camber side was thicker than that in the other side of the deviate nasal septum.CONCLUSIONThe shape and location of spetal swell body suggests its potential capacity may be to alter the nasal airflow. Additional study is required for its clinical significance.
