Otitis media with effusion (OME), a form of middle ear disease, is the most common reason for young children both to visit their family doctor and to have surgery. Almost all children have at least a single episode of OME before their first birthday and annual incidence rates exceed 50% in each of the first five years. For most children, OME occurs infrequently, but about 10-15% of children have OME during more than half of their first six years. Middle ear effusions attenuate and delay sound, causing conductive sound distortion during the crucial years for language acquisition. The many studies of OME effects on language and other indices of development have produced mixed results. However, a consensus is emerging of mild language impairment in the preschool years, with subsequent performance, emotional, and behavioral difficulties. In addition to the peripheral hearing loss produced directly by the disease, binaural and other central auditory deficits can outlive the OME. It has been unclear which children are at risk of central impairment following OME, since the children studied have generally been recruited from otolaryngology clinics. Consequently, a detailed prospective history of the middle ear status of participants has not been available. By studying six-year-old children with a lifetime known history of OME, we show in this study that only those children with a cumulative OME experience of more than about half the time during the first five years consistently have residual impaired binaural hearing.
Osteogenesis imperfecta (OI) is a hereditary disease of connective tissue and affects bone, dentine, sclera, joint, tendon, blood vessels, heart valves, and skin. Approximately 50% of the adult patients with OI have associated hearing impairment. To date, only three cases of cochlear implantation in adults with OI have been reported, but none in children. We present a case of cochlear implantation in a congenitally deaf 6-year-old boy with OI. The Nucleus 24 Contour device was successfully implanted using the suprameatal approach (SMA). At 6 months post-initial stimulation there was no evidence of non-acoustic nerve excitation (i.e. facial twitching) or discomfort, and significant progress in auditory abilities was manifested by open set word identification.
