Цель исследования – изучить характеристики костной орбиты и ее вершины в норме.

Материал и методы

Материал и методы. Исследованы компьютерные томограммы 210 человек (266 орбит) без орбитальной патологии.

Результаты

Результаты. Определены линейные показатели (горизтальный вход, вертикальный вход, длина) костной орбиты и ее вершины в норме. Выявлено, что объем костной орбиты и ее вершины в норме у мужчин и женщин имеют статистически значимые отличия. Индивидуальная асимметрия объемов костных орбит в норме выявлена у 80,95% мужчин и 82,85% женщин, асимметрия объема орбитальной клетчатки – у 47,61 и 51,42% соответственно.

Заключение

Заключение. Асимметрия средних объемов костных орбит в популяции в  норме имеет место только в пределах статистической погрешности. При этом индивидуальная асимметрия объемов костных орбит в норме достигает 3,0 см3, индивидуальная асимметрия объемов вершин костных орбит не превышает 1,0 см3. Линейные и объемные характеристики костной орбиты и ее вершины полезны при оценке степени выраженности клинических симптомов. Их необходимо учитывать при проведении дифференциальной диагностики истинного и ложного экзофтальма, также они могут иметь решающее значение при выборе тактики хирургического вмешательства.

Objective

Objective: to study the characteristics of the osseous orbit and its apex in health.

Material and methods

Material and methods. The computed tomography scans of 210 individuals (266 orbits) without orbital disease were examined.

Results

Results. The paper presents linear indicators (horizontal input, vertical input, length) of the osseous orbit and its apex in health. It is emphasized that the volume of the osseous orbit and its apex in healthy men and women has statistically significant differences. Individual asymmetry of osseous orbital volumes in health was detected in 80.95% of the men and in 82.85% of the women; asymmetry of orbital fat volume was in 47.61% of the men and in 51.42% of the women.

Conclusion

Conclusion. The asymmetry of the mean normal osseous orbital volumes in the population is only within the margin of statistical error. At the same time the individual asymmetry of osseous orbital volumes in health is as much as 3.0 cm3; that of osseous orbital apical volumes is not greater than 1.0 cm3. The linear and volume characteristics of the osseous orbit and its apex are useful in estimating the degree of clinical symptoms. These should be kept in mind in the differential diagnosis of true and false exophthalmos and these can also play a crucial role in choosing surgical tactics.
