“…A positive correlation noted between the pneumatization of mastoid air cells and that of the sphenoid sinus in our study similar to another study [15]. This correlation may be explained by the close proximity of the openings of these structures into the nasal cavity, thus they might expose to the same driving forces that control pneumatization process or other pathological events.…”

The aim of this study is to assess the pneumatization of the paranasal sinuses (PNS) and other parts of temporal bone such as mastoid air cells and to investigate if there was any association between the aeration of these structures among the three major ethnic groups in Malaysia (Malay, Chinese, Indian) as this would be representative of Asia. A retrospective review of 150 computed tomography (CT) scans of PNS and temporal bones was done and analysed. The pneumatization of each area was obtained and compared using statistical analysis. Patients with a history of previous medical or surgical problems in the intended areas were excluded from the study. The pneumatization of the mastoid air cells and other temporal bone parts were noted to be symmetrical in more than 75 %. There was a positive correlation between the pneumatization of mastoid air cells and that of the sphenoid sinus. The prevalence of Agger nasi, Haller's and Onodi cells was observed to be significantly higher in the Chinese group. Preoperative assessment of the temporal bone and PNS with CT scan may be helpful in the evaluation of their anatomical landmark and decrease the possibility of surgical complications related to 3D structures.

“…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.

“…Moriguchi (1989) observed a significant difference, with male maxillary sinus volume measuring 17.8 cm 3 and females measuring 15.0 cm 3 , based on CT exams taken for diagnosis of head injuries in 72 cases averaging 42 years old. Kim (2010) et al found that male sinus volume was significantly larger than female sinus volume, based on measurements of maxillary sinus volume using three-dimensional construction processing of CT imagery. Ariji (1994) performed CT image measurements on 115 subjects with an average age of 46.8 years and found that, while males measured 15.40 cm 3 and females measured 13.98 cm 3 , indicating a sex difference, that difference was not statistically significant.…”

Summary: In this paper, using full-body CT images of elderly and advanced elderly Japanese cadavers, we measure maxillary and other paranasal sinus volumes in order to examine the effects of age, sex, presence or absence of maxillary molars, and other factors on changes to maxillary sinus volume. The research subjects consisted of 77 of 95 cadavers donated to the Kanagawa Dental University between 2012 and 2014, which average age was 82.6 ± 10 years (33 were male, average age 79.3 ± 8.3 years, and 44 were female, average age 85.1 ± 11.7 years). Sinus volume was measured from full-body CT images on the horizontal plane and computed using the 3D volume rendering software. The average maxillary sinus volume was 31.3 ± 13.2 cm3 (average value ± one standard deviation; hereafter the same), with values of 32.9 ± 13.2 cm3 (6.7 cm 3 ~ 55.7 cm 3 ) for males and 29.6 ± 12.5 cm 3 (5.5 cm 3 ~ 52.9 cm 3 ) for females. In this report, we studied the effects of aging, sex, and state of remaining molars on changes to paranasal sinus volume in the maxillary sinus. These results give additional information about maxillary sinus volume of Japanese oldest-old peoples.

Comparative study of the pneumatization of the mastoid air cells and paranasal sinuses using three-dimensional reconstruction of computed tomography scans

Abstract: This study examined whether a similarity in pneumatization exists between the mastoid air cells and PNS of individuals; these results may be useful in understanding the normal and pathological conditions of both structures.
