A histomorphologic study of the effects of periodontal inflammation on the maxillary sinus mucosa.
Twenty blocks of human jaws obtained at autopsy and containing maxillary molar teeth with the contiguous maxillary sinus intact were prepared utilizing conventional histopathologic techniques and were studied by light microscopy. The purpose of this investigation was to confirm earlier clinical reports suggesting a close association between human periodontitis and maxillary sinus thickening and to morphologically document the nature of the sinus changes. Seventeen of 20 jaw specimens demonstrated moderate to advanced periodontal destruction with pervasive extension of the inflammatory infiltrate through the alveolar process beyond the apices of the teeth and extending to the region of the antrum. Of the 20 histologic specimens, 10 showed extensive thickening of the sinus membrane, 9 had moderate hyperplastic changes, and only 1 specimen demonstrated a normal appearing sinus. Pathologic changes in the sinus membrane included inflammatory cell infiltration, edema, fibrosis of the tunica propria, mucous-serous gland proliferation, interstitial pseudo-cyst formation, polyp formation, hyalinization of the connective tissue lining, thrombosis of blood vessels, and metaplastic and degenerative changes in the epithelial lining. This study, based on histopathologic changes, suggests an apparent direct relationship between moderate and severe periodontitis of the maxillary molar teeth and pathologic changes resulting in thickening of the maxillary sinus mucosa.
