Electrocochleography (ECochG) measures inner ear potentials generated in response to acoustic stimulation of the ear. These reflect residual function cochlea. In cochlear implant candidates with hearing, electrode can directly measure ECochG responses during implantation process. Various authors have described ability monitor by continuous measurements surgery. The measurement signals surgery i...

Introduction Intraoperative electrocochleography (ECochG) during cochlear implantation is a promising tool to preserve residual hearing. However, the time gap between insertion of electrode and acoustic feedback from audiologist surgeon causes delay. For first real-time visualization intraoperative ECochG via digital microscope (ARRISCOPE​) directly using “picture-in-picture mode” was successfu...

A 34-year-old female presented to our clinic with complaints of hearing loss, tinnitus, and severe rotational vertigo. A test battery including complete audiometric testing, auditory brainstem response (ABR) audiometry, electronystagmography (ENG), electrocochleography (ECoG), and dehydration testing was performed. Monitoring of hearing sensitivity, speech understanding, and ECoG responses foll...
