Effect of sphenoid sinus volume and pneumatization type on isolated chronic sphenoid sinusitis (fungi and polyps)

Abstract

Objectives: In this study, we aimed to investigate the association of sphenoid volume and pneumatization type with pathologies, including unilateral isolated chronic sphenoid sinusitis with polyps (ICSSwP) and isolated fungal chronic sphenoid sinusitis (IFCSS). Patients and Methods: A total of 26 patients (15 males, 11 females; mean age 49.9±15.0 years; range, 18 to 80 years) with unilateral isolated sphenoid inflammation, pathologically diagnosed as IFCSS (n=14) or ICSSwP (n=12) between January 2010 and December 2018 were included in this study. The sphenoid sinus volumes of the pathological and normal sides of the patients were compared. The sphenoid pneumatization types were also evaluated. Results: In the IFCSS group, the pathological side volume was statistically significantly higher than the healthy side volume (p<0.05). In the ICSSwP group, the pathological side volume was statistically significantly lower than the healthy side volume (p<0.05). Conclusion: Large sphenoid sinus volume is prone to IFCSS, while smaller sphenoid sinus volume is prone to ICSSwP. Therefore, it should be considered that difference in the right and left sphenoid sinus volume may have different etiological or predisposing effects for different pathologies.

Do Anatomical Variations Affect the Location of Solitary Sphenoid Sinus Fungal Balls? A 10-Year Retrospective Study

“…Isolated fungal chronic sphenoid sinusitis showed an association with a larger SS volume, whereas isolated sphenoid sinusitis with polyps was associated with a smaller SS volume. Considering the results of our study and that of Başer et al [21], the larger volume of the sellar type compared to the conchal and presellar types might be related to FB formation.…”

“…The sellar type of the SS was identified as a significant predisposing factor to the presence of unilateral SSFBs in both univariable (OR=10.00; 95% CI, 1.87-53.48; p=0.003), and multivariable analyses (aOR=8.96; 95% CI, 1.27-63.19; p=0.03) (Table 3). Başer et al [21] reported an association between SS volume and pneumatization type with pathologies (fungi and polyps). Their conclusion indicated the absence of a statistically significant difference in pneumatization types between the groups of polyps and fungi.…”
