Abstract

The aim was to measure sphenoid sinus volume on the basis of computed tomography
data post processing and to investigate the possible relationship with age, gender and mastoid
pneumatization. Sphenoid sinus volume was measured using the semi-automatic post processing algorithm
of MSCT DICOM datasets of 66 patients. There were 35 female and 31 male subjects. Median
age was 54 (range 17-84) years. Datasets were selected retrospectively from computer archives of our
hospital radiology department. Subjects with healthy sphenoid sinuses were included. Relationship of
total sphenoid volume with age, gender and mastoid pneumatization was analyzed. Data acquisition
was performed using Siemens Somatom Emotion scanner. Measurements were performed using volumetric
module of Syngo 2006G software. Virtual endoscopy and three-dimensional volume rendering
were also performed. Median sphenoid total volume (left and right together) was 10.12 cm3. Median
volume of the right mastoid was 4.86 cm3 and 5.31 cm3 on the left side. We found a significant positive
correlation between total sphenoid volume and both left and right mastoid pneumatization (Spearman
ρ=0.528, p<0.001 and ρ=0.450, p<0.001, respectively). Sphenoid volume was positively correlated with
age, but without statistical significance (ρ=0.186; p=0.136). Sphenoid volumes were larger in males than
in females, but mastoid air cells showed no gender difference. In conclusion, volumetric measurements
of paranasal sinuses may be accurately performed on the basis of MSCT data post processing. Sphenoid
volume was positively correlated with mastoid pneumatization and age. Virtual endoscopy and 3D volume
rendering may accurately display anatomic structures of sphenoid sinuses.
