Otovent autoinflation devices: who should use them, and how

Various studies have shown that up to 80% of all children have significant episodes of eustachian tube dysfunction and otitis media with effusion of varying duration before attending school.

In addition to causing pain, reduced hearing and eardrum pathology, otitis media with effusion predisposes to recurrent acute middle ear infection. Chronic ear disease occurring in later life, such as chronic otitis media and cholesteatoma, are also directly attributable to recurrent otitis media in childhood.
