Keros classification among Jordanian population

ABSTRACT

To evaluate the prevalence of each KEROS subclass among Jordanian population, and to compare between subclass distribution in right and left side, and also between different genders. Retrospectively evaluating computed tomography studies for paranasal sinuses of 100 different patients, the depth of lateral lamellae of cribriform plate was measured and this was plotted against the different subtypes of Keros classes considering gender variations. The favorable classes were found to be II, I and III in order, having percentages of 70.5%, 22% and 7.5% respectively. Minimal male to female variations were found as well as minimal right to left variations. Racial variations were noted when comparing our study results to other studies worldwide. Significant racial variation is noted when considering Keros classification among population. Keros categorization of patients is emphasized when performing paranasal sinuses Computed Tomography
