Using Electrocochleography During Cochlear Implantation of the Neuro Zti.

"Before the mastoidectomy, the ear canal is cleaned, the insert earphone is connected to the Eclipse (Oticon Medical software) preamplifier and placed into the ear canal. The EEG scalp electrodes (active, ground electrode) are placed on the patient's head. After the posterior tympanotomy, the reference electrode (eCochG probe) is placed on the cochlear promontory.~The CI electrode array will be inserted following one of the two possible techniques while the eCochG will be recording. The surgeon will either manually insert the array using the Oticon Medical stylet and following the surgery guides and recommendations from Oticon Medical or will control the Robotol insertion angle and drive the robotic arm in the same way."
