Mankekar G. (editor). Implantable hearing devices other than cochlear implants
119 pp. Springer India 2014
Conventional hearing aids have served to amplify residual hearing and provide hearing rehabilitation. Despite technological advances, conventional hearing aids still have many limitations. They amplify all sounds and not only speech sounds. This makes it difficult for the wearer to understand speech clearly. Hearing aids require frequent battery changes, have to be worn with customized moulds. In tropical countries, digital hearing aids require frequent dehumidification. Implantable hearing devices can be classified as active or passive. Active middle ear implants depend upon an external source of energy for their functioning. Much has been written about cochlear implants and auditory brain stem implants. So this book will attempt to dwell on passive implants and the other currently marketed active implants namely Bone Conduction Implants, Vibrant Soundbridge, Esteem and Maxum. The chapter on passive implants discusses the importance of Eustachian tube function, role of a healthy middle ear mucosa and biofilms in the acceptance of the various middle ear prosthesis. Bone conduction devices, Vibrant Soundbridge, Maxum and Esteem Implants can help those who cannot be provided with hearing rehabilitation with either conventional hearing aids or passive middle ear implants.
