“…We used the ImageJ software with the planimetry method and Cavalieri's principle in our calculations. While previous studies (6,7,21,30) report maxillary sinus volumes to range from 11.1 cm 3 to 23.0 cm 3 , our results were found to be consistent with those reported in the literature.…”

Objective: To investigate the effect of hard palate angulation caused by septal deviation on the volume of the maxillary sinus. Methods:Coronal computed tomographic (CT) scans of 1568 patients aged from 18 to 60 were examined. CT scans of 402 patients were included in the study. On these scans, the maxillary sinus volume, the angle of the nasal septal deviation, and the angulation of the hard palate were calculated using the ImageJ software. Each maxillary sinus volume was statistically compared with each other and with those in the control group. Correlations between palatal angulation and septal deviation were determined.Results: Deviated nasal septum whether with or without deflection of the hard palate was noted to have caused changes in the volume of the maxillary sinus in both female and male patients. The volume of the maxillary sinus on the deviated side was less than that of the opposite side, and the differences between the volumes of both sinuses were statistically significant (p<0.05). No significant differences were noted when compared with the control group. A positive correlation was observed between the nasal septal deviation angle and the angulation of the hard palate. Conclusion:Regardless of whether or not it affects the hard palate, nasal septal deviation reduces the volume of the maxillary sinus on the deviated side but does not affect the total volume of the maxillary sinuses. Significant differences between the volumes on the two sides can lead to facial asymmetry.

“…The mean values of the maxillary sinus volumes have been reported to range from 18.0 ± 6.0 cm 3 to 23.6 ± 6.4 cm 3 in previous studies [19,25,31,32,41,44,45]. The results of the frontal sinus volumes in this study were larger than those of previous studies [19,30,31,41,45]. The mean values of the frontal sinus volumes have been reported to range from 4.0 cm 3 to 11.6 ± 4.2 cm 3 in previous studies [19,30,31,41,45].…”

“…However, the protrusions don't appear in all cases. The prevalence of the protrusions is quite variable, which may affect the success of transsphenoidal endoscopic surgery [6,[8][9][10][11][12][13]. The prevalence of protrusion of ICA is not conclusive, ranging from 5.2% [14] -32.8% [15], 48.5% [16] and 67.7% [8], depending on the degree of individual pneumatization and the definition used in each study.…”

The relationship between the volume of sphenoid sinus (SS) and the prevalence of internal carotid artery (ICA) and optic nerve (ON) protrusions in the SS was studied by using high-resolution CT imaging. The ICA and ON protrusions in SS were observed in randomly selected normal head CT scanning images from 350 adult subjects. According to the incidence of ICA protrusion, three groups were divided into no ICA protrusion (70.75%), unilateral protrusion (8.68%) and bilateral protrusions (20.57%). The ON protrusion accounted for 16% in 350 subjects and accompanied absolutely with ICA protrusion, but ICA protrusion appeared without accompanying with ON protrusion. The SS volume depended upon the protrusions in it and showed statistical differences, without ICA protrusion, the smallest size (11.16 ± 1.60) cm 3 ; the unilateral protrusion, medium size (14.20 ± 1.80) cm 3 and the bilateral protrusion, the largest size (25.03 ± 2.21) cm 3 . By observing 3D reconstructed models of ON and SS, we found ON was adjacent to SS (46%) and to posterior ethmoid sinuses (44%). The current study indicates that SS volume is varied with numbers of the protrusions and that ON location varies with the pneumatization of SS. Our results provide an anatomical basis to the surgeries for SS and its surrounding structures.
