In 30 ears from 24 children with chronic secretory otitis the density of goblet cells and of glands was determined on biopsies from the anterior part of the promontory. The goblet-cell and gland density proved to be highly increased in all cases, with marked individual variations. The median density of goblet cells was 142 cells/field, corresponding to 8,000 cells/mm-2. This substantiates the fact that in chronic secretory otitis the mucous secretion is a product of goblet cells and mucous glands and confirms the secretory pathogenesis of the disease.
