Abstract
Aim: This study evaluated radiographic variations and measured dimensions of the non-pathologic
frontal sinuses.
Study Design: Retrospective.
Place and Duration of Study: Orthodontics Department, Dental School, Shahid Beheshti
University of Medical Sciences, 2003 to 2012.
Methodology: Subjects older than 12 years with no sinus pathology were included. Borders of the
frontal sinus were traced. Line drawings were scanned, and sinus dimensions were calculated by
computer software by two examiners. In addition, asymmetry and shape of superior margin of
sinus were evaluated. Gender differences were analyzed by independent sample t-test and chi
square with a 0.05 level of significance.
Results: A total of 66 subjects were included (40 female and 26 male). Height, width and area of
the frontal sinus in the sagittal plane were 2.26 cm, 1.13 cm and 1.37 cm2, respectively. The
corresponding numbers in the frontal plane were 2.79 cm, 5.00 cm and 7.04 cm2, respectively. Although all dimensions were larger in men than in women, it was not significant (P>0.05). Most of
the cases had relatively symmetric frontal sinus.
Conclusion: Size and shape of the frontal sinus varies among individuals. Frontal sinus is
relatively larger in men than women.
