| Summary: | Background. The study of morphometric variability of the sella turcica and pituitary
gland in individuals with different types of skull base is of theoretical importance and
remains relevant in practical medicine for the diagnosis of pathological processes and the
development of new methods of surgical intervention. The purpose of the research is to
study the typical variability of the linear characteristics of the sella turcica, pituitary gland
and their relationship according to MRI data. Materials and methods. The object of the
study was 100 magnetic resonance imaging of the brain of men and women of the 1st and
2nd periods of adulthood, divided according to the size of the basilar angle into three craniotypes:
flexi-, medio- and platybasilar. The dimensional characteristics of the sella turcica
and pituitary gland were studied using the digital craniometry method, and a statistical
analysis of the data obtained was carried out. Results. With an increase in the values of the
basilar angle of the skull base from the flexibasilar type to the platybasilar type, a change in
the linear parameters of both the sella turcica and the pituitary gland occurs. In the sella turcica,
the length and width increase by 6.9% and 13.6%, respectively, while the height decreases
by 13.0% (p < 0.05). The pituitary gland is characterized by a statistically significant
increase in its length by 19.5% and width by 11.2% (p < 0.05), while the height of the
gland does not change. Correlation analysis revealed relationships of different strength and
direction between the longitudinal and latitudinal parameters of the sella turcica and the pituitary
gland. Conclusions. The angle of the skull base (craniotype) affects the anatomical
characteristics of the sella turcica and pituitary gland, as well as their relationship. |
