“…Compared to other studies that diagnosed paranasal sinusitis by means of MRI, the prevalence noted in our study was lower than that noted in studies from Denmark (31.7 %) 20 , Japan (33.8 %) 23 , and Norway (66 %) 12 . We believe that this variation could be due to the use of different diagnostic criteria and research techniques.…”

“…Among all the participants in this study, 49.2 % were men. We found that men were approximately 86 % more likely to have paranasal sinusitis than women (adjusted OR = 1.86, 95 % CI = 1.54-2.24), which is consistent with the results of studies from Asia 21,23,27 . However, some surveys from developed Western countries found that women were at a higher risk of developing paranasal sinusitis 6,9,28 .…”

Background: Paranasal sinusitis is frequently encountered in clinical practice. The application of imaging techniques has highlighted the high incidence of incidental sinus abnormalities. Additionally, the adverse impact of smoking on paranasal sinusitis has been verified; however, few studies have compared the characteristics of affected sinuses between non-smokers and smokers. This study aimed to assess the prevalence of paranasal sinusitis detected by magnetic resonance imaging (MRI) and determine its characteristics and affected sinuses in smokers. Methods: This cross-sectional study involved 4813 participants from two communities in Shanghai, China. Demographic data were recorded, and participants underwent a physical examination and head MRI. Logistic regression analysis was used to examine the relationship between smoking and paranasal sinusitis and the Cochran–Armitage test to analyze age-specific prevalence of paranasal sinusitis in smokers versus non-smokers. Results: Among the 4813 participants (2368 men, 2445 women; mean age, 53.0±10.1 years), the prevalence of paranasal sinusitis was 15.4 %, being higher in men (20.1 %) than in women (10.8 %; p<0.001). Paranasal sinusitis was significantly associated with smoking (adjusted OR=1.37, 95 % CI=1.10–1.70), and in smokers, it occurred most often in the maxillary sinus (19.1 %), followed by ethmoid (2.9 %), frontal (2.2 %), and sphenoid (1.8 %) sinuses. Conclusion: The prevalence of paranasal sinusitis was 15.4 % in Chinese adults aged 35–75 years. This gradually increased with age, reaching a peak at 55 years and stabilizing thereafter. In smokers, sinusitis occurred more often in the anterior nasal sinuses. (Clinical Trials. gov number: NCT00926172)

“…This wide range of variation in the reported prevalence rates can be attributed to heterogeneity in the study design, methodology, study population, and definitions of abnormal findings. 17 20 21 In our study population, 197 (32.0%) patients had abnormal findings in the paranasal sinuses. Mucosal thickening was the most common abnormal finding, followed by retention cysts.…”

Magnetic resonance imaging study of incidental findings in the paranasal sinuses and ostiomeatal complex

et al. 2022

Purpose This study aimed to assess incidental abnormal findings in the paranasal sinuses and anatomical variations of the ostiomeatal complex (OMC) on magnetic resonance imaging (MRI) scans. Materials and Methods MRI scans of 616 patients (mean age, 44.0±19.4 years) were evaluated. Prior to obtaining the MRI scans, a checklist of patients’ clinical symptoms was filled out after obtaining their consent. The Lund-Mackay classification was used to assess the paranasal sinuses and OMC. The prevalence of abnormal findings and their associations with patients’ age, sex, and subjective symptoms were analyzed by the chi-square test, independent-sample t-test, and analysis of variance. The level of significance was set at 0.05. Results Abnormal findings in the paranasal sinuses were detected in 32.0% of patients, with a significantly higher prevalence in males ( P <0.05), but no significant association with age ( P >0.05). Epithelial thickening and retention cyst were the most common abnormal findings in the paranasal sinuses. According to the Lund-Mackay classification, 93% of the study population had normal sinuses (score<4). Concha bullosa and paradoxical concha were detected in 15.3% and 3.4%, respectively, with no significant association with the presence of septal deviation or Lund-Mackay classification ( P >0.05). Conclusion Considering the relatively high prevalence of abnormal findings in the paranasal sinuses, it appears that clinical symptoms alone are not sufficient to diagnose sinusitis. A more accurate strategy would be to assess radiographic images of the paranasal sinuses and use a classification system. Sinusitis should be suspected in patients receiving a high score in this classification.

“…Accordingly, we would hypothesize that any ancestry-based differences in sinusitis susceptibility linked to MS height dimensions are most likely to appear during late adolescence or early adulthood. Further, as there is some evidence that inferior pneumatization towards the maxillary alveolus may continue throughout adulthood-particularly due to tooth loss and alveolar resorption (Sperber, 2001; but see Ariji et al, 1994)-our results suggest that increased SFMS dimensions in older adults could be a contributing factor to their greater risk of developing sinusitis (Hoover et al, 1997;Slavin, 1997;Sugiura et al, 2018). For the purpose of this study, we avoided crania with moderate-to-severe alveolar resorption to mitigate the effects of the sinus floor (see Section 2); as such, both of these growthrelated possibilities warrant further investigation.As with previous studies investigating MS size and shape (Butaric & Maddux, 2016;Ikeda et al, 1998;Noback et al, 2016;S anchez Fern andez et al, 2000), our study further highlights the limited amount of clinically relevant information that can be gleaned from MS volume as an isolated measure of MS morphology.…”

Paranasal sinus drainage is mediated by mucociliary transport and gravity.However, human orthograde posture, along with the superior positioning of the maxillary sinus (MS) ostium, increases reliance on the mucociliary system.Previous research has thus suggested that differences in MS size and shape may impede mucociliary clearance, potentially contributing to disparities in sinusitis susceptibility. To further investigate this hypothesis, this study collected 29 three-dimensional (3D) coordinate landmarks and seven linear measurements of MS morphology from 167 computed tomography (CT) scans of crania of European, East Asian, or Equatorial African ancestry. MANOVA results reveal the Asian-derived individuals are characterized by both a significantly taller MS (F = 14.15, p < 0.0001) and a significantly greater distance from the MS floor to the ostium (F = 17.22, p < 0.0001) compared to those of European and African ancestry. A canonical variate (CV) analysis conducted on 3D landmark data provides corroborative results, distinguishing Asianderived individuals predominantly on the basis of a relatively lower MS floor.As a greater distance between the MS floor and ostium may impede mucociliary clearance, our results suggest MS anatomy may be a more prominent factor in chronic sinusitis among individuals of Asian ancestry compared to those of European and African ancestries. This provides tentative evidence of an anatomical etiology for chronic sinusitis even in the absence of anatomical variants/abnormalities (e.g., nasal polyps, concha bullosa, Haller's cells, and Agger nasi cells). Further research into the relationship between MS anatomy and sinusitis, in addition to socioeconomic inequalities of healthcare, is warranted to continue evaluating possible contributions to health disparities.
