Abstract
Objective
to investigate the volume and linear measurements of the frontal sinuses by means of a three-dimensional software using helical computed tomography images.
Materials and methods
The samples consisted of 36 tomographic images from 22 women and 14 men aged between 18 and 86 years old. The ITK/SNAP software was used for image segmentation, analysis of volume data, and linear measurements (i.e. height, width and depth).
Results
The mean volumes of the left and right frontal sinuses were 3.945 mm3 (SD = 2.803) and 3.423 mm3 (SD = 2.835). The mean linear measurements were the following: right-side axial depth of 16.1 mm (SD = 7.6), left-side axial depth of 17.0 mm (SD = 5.8), right-side sagittal height of 19.0 mm (SD = 11.1), and left-side sagittal height of 20.5 mm (SD = 9.8), with no statistically significant differences. The right-side axial width of 19.0 mm (SD = 6.8) and left-side axial width of 22.4 mm (SD = 9.1) in women and right-side axial width of 21.6 mm (SD = 12.9) and left-side axial width of 26.5 mm (SD = 9.8) in men, with statistically significant difference (P = 0.0264) for the left side.
Conclusion
There was a significant difference only for axial width, with the left side having higher values compared to the right side.
