- 1. Purpose
The purpose of this study was to evaluate the size of normal maxillary sinus by measuring the volume, width and height of sinus and analyzing their correlation and difference of the sinus respectively between sexes and on the left and right sides using computed tomography.
2. Materials and Methods
The study population comprised 60 patients (120 maxillary sinuses) who had taken CT in the Department of Dental Radiology, Seoul National University, Dental Hospital, between December 2012 and June 2013 who were no specific symptom, pathosis, surgical history.
The mean transverse width, antero-posterior width, height and volume of the maxillary sinus were 33.44±4.55mm, 36.51±4.87mm, 45.53±5.62mm, 21.61±6.85cm3, respectively. Differences of right and left were 2.21±1.75mm, 1.50±1.20mm, 1.65±1.36mm, 2.10±1.77cm3, respectively. Degrees of asymmetry were 6.46±5.12%, 3.76±2.99%, 3.57±2.92%, 9.54±7.81%, respectively. There was a significant sex difference (p<0.05), no significant difference on both sides (p>0.05) in all parameters.
The outcome of the present study indicated that males have larger maxillary sinus than females, all of the measurements showed no significant difference between the right and left sides.
