ANATOMICAL CHARACTERISTICS OF THE LABYRINTH AND COCK CREST OF THE HUMAN ETHMATE BONE IN THE FIRST PERIOD OF MATURE AGE ACCORDING TO COMPUTER TOMOGRAPHY DATA

The aim of the study is to provide an anatomical description of the labyrinth and cock crest of the ethmoid bone in humans in the first period of adulthood based on computed tomography data. Materials and methods: The object of the study was 60 computed tomograms of the skull of people in the first period of mature age (22-35 years old - men, 21-35 years old - women), of different sexes, without pathology of the paranasal sinuses. Results: In the first period of mature age, the value of the anteroposterior size of the labyrinth of the ethmoid bone on the right was 36.39±4.25 mm, on the left – 36.04±4.44 mm, with a range of values ​​from 28.30 to 46.61 mm. The anteroposterior size of the ethmoid labyrinth on the right and left was 1.4 times greater than the height and 3 times greater than the width. The height of the ethmoid labyrinth in females on the right and left was 26.72±3.29 mm and 27.32±3.39 mm, respectively, and was significantly greater than this indicator in males. The height and anteroposterior size of the cock crest in the studied group were equal, amounting to 13.98±3.76 mm and 13.39±2.63 mm, respectively, and were 3 times greater than its width. In 25%, a pneumatized middle nasal concha was observed, and in 21%, a pneumatized cock crest. Conclusion: The anatomical characteristics of the ethmoid bone, as an element of the nasal cavity, paranasal sinuses, internal base of the skull, and orbit, are of great importance for choosing the optimal surgical approach, in particular in endoscopic endonasal intervention.
