“…Nevertheless, the strict application of these criteria may leave cases of AOM undiagnosed, so in 2007 the consensus document on AOM of the Spanish Association of Pediatrics and Otorhinolaryngology 19 specified that the diagnosis be "confirmed AOM" when all three criteria are met, but if there is only evidence of otalgia and it is not possible to perform an otoscopy (if, for example, there is a manifest technical difficulty or cerumen that cannot be extracted) or, on the contrary, the otoscopy is very significant but the otalgia is not clear or confirmed (due to the age of the child, uncertainty of the family members, etc), the consensus proposes that the diagnosis be "probable AOM". And if it is accompanied by a recent catarrh of the upper respiratory tracts, along with factors indicating a poor prognosis (AOM in a child younger than six months, relapsing or recurrent AOM, first-degree family history of middle ear sequelae due to AOM) probable AOM will be treated as a "confirmed AOM".…”
