ABSTRACT

The purpose of the investigation was to study the efficacy of closing the bone defect in facial walls of the frontal and maxillary sinuses, formed as a result of their purulent inflammation, by porous permeable titanium nickelide. Analysis of the experimental data (18 dogs) and clinical observations (20 patients in whom the anatomic structure and function of frontal and maxillary sinuses with osteomyelitis were restored by an antibiotic pooling implantation material) gives evidence that the material can be well used to reconstruct an organ with an infected wound. The porous structure of the bioinert graft facilitates the ingrowth of osteogenic tissues, which becomes packed in the bone matrix without any intermediate connective tissue layer.
