Pathology of chronic maxillary sinusitis and possible blood changes

Specimens from the diseased sinuses in cases of long standing chronic maxillary sinusitis were taken during Caldwell-Luc operation. Histopathological examination revealed hyperplasia of the epithelium which may invaginate forming pouches and subepithelial nests. The secretory glands increase both in number and size indicating the chronicity of the disease.
