Otitis media Glue ear 2016-03-17T15:05:24Z UMLS:C0029883 Middle ear is filled with glue-like fluid instead of air. In some contexts, glue ear is used interchangeably with otitis media with effusion (OME) (PMID:21653931). Some authors use glue ear to refer to a subtype of OME characterized by thick, glue-like fluid buildup in the middle ear (mucoid otitis media) (PMID:10993548). Serous otitis media is usually responsive to medical treatment, whereas mucoid otitis media is not. This term refers to the mucoid subtype. SNOMEDCT_US:78868004
