Exploring the Use of ECochG Testing During Electrode Insertion in Cochlear Implant Surgery

Investigation of a new ECoChG system (Electrocochleography) during the surgical insertion of cochlear implants, for patients with Advanced Bionics devices. The sound recordings created may be useful in aiding the surgeon to better implant the patient by letting him or her know if they are damaging the ear during implantation in real time Patients will be followed up for 1 year post surgery within our trial, and have a further 3 ECochGs performed in the clinic setting, (6 weeks, 6 months, 1 year) through their implants.
