The role of orbital wall morphological properties and their supporting structures in the etiology of “blow-out” fractures

The stiffness and strength of the orbital walls are proportionally dependent on the anatomical structures which support and strengthen these walls from the opposite side. The medial wall is therefore strong due to the support of ethmoid cells. The floor is stronger the less surface there is and the more supported it is by trabeculae of the maxillar sinus. The strength of the upper and lateral walls are proportional to their thickness. The...
