Protrusion of the optic nerve canal into the Onodi cells on CT Scan
Main Article Content
Abstract
To examine the association of Onodi cells with the optic nerve on CT scans we conducted a cross-sectional study, analyzing CT scans of paranasal sinuses in 280 posterior ethmoid air cells from 140 patients (44 males and 96 females) aged 18 or older, without abnormality in the paranasal sinuses and optic nerve anatomy. The prevalence of Onodi cells was 44.29%, with 27.42% on the right, 29.05% on the left , and 43.54% bilaterally. The incidence of protrusion of the optic nerve into the Onodi cells was 38.7%, with 43.47% on the right side and 18.18% on the left side. The rate of optic nerve exposure on the right was 4.5%, on the left was 6.5%.
