This study evaluated the histopathologic changes in the round window niche. ,
and membrane in cases of chronic suppurative otitis media. The pathologic
process was found in all subjects. Fibrocystic or fibrous tissue was most commonly
seen, while active granulation was less developed. The round window membrane
was thicker and inflamed throughout its layers. Inflammatory invasion of the inner
ear through the membrane: is very rare, because the thickened membrane has a
protective role for spreading of infection.
