This e-book on Cochlear Implants (CI): New and Future Directions covers the cochlear implant from its inception to recent advances culminating in the cochlear implants in clinical use today. It also covers future horizons. All the authors of the different chapters are CI surgeons known worldwide, many of them pioneers of their own technique and also prominent audiologists, clinical engineers, and researchers. The first few chapters deal with historical events: Benjamin Franklin’s electric stimulation of hearing followed by many pioneers ending with the first cochlear implant with FDA approval by House in 1984 and by Clark in 1986. India was part of history and was touched upon as cochlear implantation started in 1987 with mono- and multi-electrode systems. The evolution of the technology of implants took 35 years, and the changes made by CI companies with clinical sup-port are elaborated. The book then turns to medical and surgical issues. Surgical anatomy of the temporal bone and recent advances in CT scan and MRI are illus-trated. Candidacy for selection of potential candidates has changed over the years and varies from country to country; therefore, it is discussed in detail. Next we have prognostic modeling and machine learning in cochlear implantation which is a new direction which could be used to look for better audiological and surgical outcomes. The next few chapters are on different CI surgical techniques each one authored by doyens and pioneers, namely CI surgery using posterior tympanotomy and cochle-ostomy, CI surgery using the Veria technique, and CI surgery using the round win-dow approach. Also included are cochlear implants in cases with inner ear abnormalities, bilat-eral cochlear implants, and subtotal petrosectomy with cochlear implantation. In recent times with new indications we have chapters on CI surgery in case of unilat-eral hearing loss and hearing preservation in implants with residual hearing, chil-dren undergoing cochlear implant surgery, explantation, and reimplantation, and complications of cochlear implant surgery. Robot-assisted cochlear implant surgery is the most recent advance, as it can be used for direct cochlea access, cochleos-tomy, and precise insertion of electrodes. Image-guided cochlear implant surgery and recent advances in CAS are discussed.
