Chronic serous or mucoid otitis media

Description

Chronic serous or mucoid otitis media is probably the most common form of sub-acute middle ear disease found in the developed world. It typically lingers following otitis media, when the fluid in the ear, formed by the infection, does not clear spontaneously. The tympanic membrane is intact but the middle ear is liquid- fluid filled. This presumably puts the middle ear at risk for further infection and often worsens hearing by about 30 dB. This is most frequently found in children and can interfere with language acquisition and learning.
