Serous otitis media and immunological reactions in the middle ear mucosa.
An immunohistochemical study was performed on the middle ear mucosa of 21 children with chronic serous otitis media (SOM). In 86% of the patients a highly organized lymphatic tissue was found in the middle ear mucosa which can be regarded as part of the mucosa associated lymphoid tissue (MALT). Features of an immune complex mediated (type III) hypersensitivity reaction were absent.
