Electrocochleography

In this chapter, we review firstly the main features of different components of ECochG potentials and their underlying generators and then focus on the changes induced by cochlear hearing loss on ECochG potentials. The second part will consider four main topics 1) the use of ECochG in the diagnosis of Mènière disease; 2) the inclusion of ECochG recordings in the candidacy assessment protocol for cochlear implantation in children; 3) the features of cochlear receptor and auditory nerve potentials recorded from patients with auditory neuropathy (AN); and 4) the use of ECochG recordings in hearing threshold assessment in children discharged from NICU.
