title: Chronic middle ear effusions (secretory otitis media).
abstract: Middle ear effusions are common in childhood and are a serious cause of disability and learning difficulty. The symptoms and signs tend to be obscure, but a high index of suspicion should be cultivated with primary care physicians, paediatricians, schoolteachers, and parents. Treatment is medical in the early stages, but a high proportion of patients require the surgical insertion of pressure equalization tubes. The condition tends to run a protracted course, but the eventual outlook is favourable.
