Purpose Detailed assessment of the extrasinusal pneumatization of the superior and middle turbinate (SCB, MCB), olfactory
fossa (OFP), and nasal septum (NSP) in coronal and sagittal sphenoid sinus (SS) pneumatization types provides a precise
understanding of the surgical corridors used for skull base surgery. We aimed to analyze the relationships among these variations using computed tomography (CT) images.
Methods CT images of 153 patients were retrospectively analyzed for all types of sinonasal pneumatizations and volumes
of SCB and sphenoid sinus, together with the prevalence of mucosal thickening of the sphenoid sinus (MTSS).
Results The prevalences of cellular, extensive, and complete SCB were 28.6%, 21.1%, and 23.5% in prepterygoid; 38.1%,
42.1%, and 35.3% in prerotundum; and 33.3%, 36.8%, and 41.2% in postrotundum CSSP types, respectively. The frequencies of lamellar, bulbous, and extensive MCB were 29%, 14.3%, and 33.3% in pterygoid, 38.7%, 57.1%, and 25.9% in prerotundum, 32.3%, 8%, and 40.8% in postrotundum CSSP types, respectively. SCB and MCB were observed unilaterally at
24.8% and 30% and bilaterally at 12.8% and 32.7%, respectively. OFP, NSP, and MTSS were detected at 24.2%, 31.4%, and
27.5%, respectively. Increased age was signifcantly associated with a lower probability of pneumatization in SS and MCB.
Conclusions The data obtained showed that the degree of SS pneumatization signifcantly afected the frequencies of the
SCB, MCB, OFP, NSP, and MTSS. Also, the SCB volume is signifcantly related to the CSSP types. Preoperative CT evaluation is crucial for surgeons to be aware of these variations and to avoid iatrogenic injury.
