INAL, MIKAIL/0000-0003-0642-7913; ozdemir, adnan/0000-0003-0652-5396WOS: 000462155700016PubMed: 30617426ObjectivesWe investigated the relationship between Onodi cells and optic canal by paranasal sinus computed tomography (PNSCT).MethodsIn this retrospective study, 508 PNSCT (265 males and 243 females) was examined. Onodi cell presence, pneumatization types, optic canal types; and also sphenoid sinusitis and anterior clinoid process pneumatization were evaluated.ResultsThe prevalence of Onodi cells was 21.2% of the patients. Onodi cells were observed 40.7% on the right side and 25.9% on the left side. In 33.4% of the patients, bilateral Onodi cells were present. Male/Female ratio was 24.5%/17.6%. Onodi cell types were detected as Type I>Type II>Type III bilaterally. There was a positive correlation between the right and left Onodi cell types (pType I>Type II>Type III. bilaterally. There was a positive correlation between right and left optic canal types. Onodi cell presence and ACP pneumatization were found as statistically significant (p
