Проведено рентгенометрическое исследование компьютерных томограмм костного основания задней черепной ямки и проекционных вариантов расположения мозговых структур относительно костных ориентиров 116 пациентов без патологии костей черепа и головного мозга.</p></sec><sec><title>Результаты</title><p>Результаты. Определены основные линейные (длина, ширина, глубина) и угловые (угол схождения пирамид, пирамидно-затылочный угол, угол ската, угол наклона чешуи затылочной кости) рентгенометрические параметры, обусловливающие форму задней черепной ямки. По вариантам сочетания крайних значений этих параметров выделены наиболее часто встречающиеся формы (длинная узкая глубокая, длинная широкая мелкая, длинная узкая мелкая, длинная широкая глубокая, короткая узкая мелкая). Определены варианты расположения мозговых структур в пределах проекционных плоскостей.</p></sec><sec><title>Заключение</title><p>Заключение.

The main linear (length, width, depth) and angular (a pyramidal convergence angle, a pyramidal occipital angle, a slope angle, and occipital squama inclination) roentgenometric parameters determining the shape of the posterior cranial fossa were determined. The most commonly encountered (long narrow deep, long wide fine, long narrow fine, long wide deep, and short narrow fine) shapes were identified according to the combination of the extrema of these parameters. The variants of the location of brain structures were determined within the projection planes.</p></sec><sec><title>Conclusion</title><p>Conclusion. There were the roentgenometric parameters and craniocerebral ratios, which are of value in the individual planning of surgical approaches to the structures of the posterior cranial fossa.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерная томография</kwd><kwd>задняя черепная ямка</kwd><kwd>анатомия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computed tomography</kwd><kwd>posterior cranial fossa</kwd><kwd>anatomy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гайворонский А.И.
