Ossicle Coupling Active Implantable Auditory Devices: Magnetic Driven System

摘要

Active auditory implants, such as the Maxum, provide significantly improved hearing function compared to hearing aids in patients with moderate to severe hearing loss who are not reaching their cochlear hearing potential. The speech perception gap (SPG), defined as PB Max (phonetically balanced maximum) minus word recognition score with hearing aid, is a useful measure of inadequate hearing aid performance. The Maxum middle ear implant provides significantly improved performance over hearing aids in patients with significant SPG because of superior high frequency gain. Patients with PB Max 60% or greater with SPG are possible candidates for the implant.
