Aim. Determine the variability of the parameters of the structural formations of the ethmoid bone (EB). Material and Methods. On the 49 skulls of adults, the length and width of the cribriform plate (CP) were craniometrically studied. At 58 KT-grams, the length and width of the ethmoid labyrinth (EL) are determined. Results and Discussion. The length of the CP is 21.5±0.2 mm (Min-Max=14.7-26.0 mm, σ=2.7 mm, CV=12.6%), the width of the CP varies in the range of Min-Max=4.6-20.1 mm and on the average is: at the level of the anterior third of 7.2±0.1 mm (σ=2.2 mm, CV=27.6%), the middle third - 11.1±0.2 mm (σ=1.8 mm, CV=18.5%), the posterior third - 12.9±0.2 mm (σ=2.8 mm, CV=21.1%). The length and latitudinal parameters of EL do not have statistically significant bilateral differences (p>0.05). The average length of the EL is 36.0±0.3 mm (Min-Max=27.3-45.3 mm, σ=3.9 mm, CV=12.4%). The width of the EL of the anterior third is 8.2±0.2 mm (Min-Max=4.8- 17.3 mm, σ=2.5 mm, CV=29.3%), posterior third - 10.0±0.2 mm (Min-Max=3.9-19.4 mm, σ=4.7 mm, CV=32.0%). Conclusions. The prevalence of latitudinal parameters of the EB in the posterior third was established in comparison with the anterior third (EP at 79%, EL at 22%). The long-latitudinal parameters of the latticed bone have an average and strong degree of variability.
