Some peculiarities of osteomedullary interrelations at the level of the lateral wall of the maxillary sinus.

Several structural aspects in the lateral wall of the maxillary sinus are shown, revealing the existence of some peculiarities of the osteomedullary relationships at this level, as for instance: a) a great density of vascular canals, b) a marked collagen density and a high degree of polymerization of the ground substance pleading for a great stability of the osseous structure, and c) a relative cellular scarcity inside the marrow-like spaces as an expression of a reduced reactive ability of bone marrow. It is considered that these peculiarities are not merely determined by specific functional needs of the bone as a tissue, but mainly by subordination of the latter to the requirements of the higher-ordered structural and functional levels served by a certain osseous zone.
