Cochlear Implants
From Principles to Practice

A cochlear implant is a surgically implanted electronic device that provides a sense of sound to a person who has a severe or profound hearing loss. A cochlear implant does not cure deafness or hearing impairment, but is a prosthetic substitute which directly stimulates the cochlea. There are over 250,000 users worldwide with 12,000 in the UK.

This book is a multidisciplinary guide to cochlear implantation in children and adults with sensorineural hearing loss (where the root cause lies in the inner ear or sensory organ, ie the cochlear and associated organs).

Beginning with discussion on the aetiology of hearing loss and assessment of cochlear implant candidacy, the next chapter discusses preoperative cochlear implant imaging.

Each of the following sections provides in depth coverage of different types of cochlear implantation and their potential outcomes. The final sections examine miscellaneous topics such as music perception in cochlear implantation, drug eluting electrodes, cost effectiveness, and reliability reporting.

Authored by internationally recognised, US-based specialists, the text is further enhanced by clinical and surgical photographs and illustrations.
