Abstract

Objective: The objective of this retrospective study was to determine the prevalence of the data obtained from anatomical structures of ethmoid bone evaluated morphometrically on cone beam computed tomography (CBCT) images in a Turkish subpopulation.
Methods: The CBCT images of 200 patients which met the study criteria were selected from the digital database of our university. The medial ethmoid roof height (MERH), cribriform plate height (CP), the height of the lateral lamella of the cribriform plate (LLCP) were evaluated retrospectively using. All the data were grouped by age, side and gender.
Results: For MERH; the mean length for left and the right side was 25.55 ± 3.00 mm and 25.24 ± 3.01 mm, respectively. The mean LLCP heights in right and left side were 4.98±2.12 mm and 4.49 ±1.64 mm, respectively. In the female, the mean of right and left LLCP height were 5.07±2.07 mm and 4.48±1.63 mm, respectively. In the male, the mean of right and left LLCP height were 4.83±2.21 and 4.50±1.66 mm, respectively. It was found that LLCP height did not have a statistically significant correlation with gender (p>0.05). There was a statistically significant negative correlation between LLCP and CP (p<0.05).
Conclusion: Morphological differences of the anatomy of ethmoid bone are shown in this study. The anatomical structures showing changes due to factors such as side, age, gender, and race should be examined in three dimensions before the operation.
