    Abstract:

    A cochlear implant for use in children must take into account the high incidence of middle ear infection in this age group. A scala tympani electrode that traverses the middle ear and round window will likely act as a conduit by which infection can spread to the inner ear and potentially to the CNS. In this study an attempt was made to reestablish a separation of the cochlea from the middle ear by developing a seal around the implant at the level of the round window. A series of cats were implanted with simulated cochlear prostheses consisting of either a plain Silastic cylinder, a Silastic cylinder wrapped with autogenous fascia, or a Silastic cylinder with a cuff of bioactive ceramic. Middle ear infection was induced, followed by histologic examination. Bioactive ceramic appears to have some merit as a round window sealing material, while fascia was shown to be of no value. Intracochlear infection, when it did occur, was limited to the basal regions of the cochlea.
