Abstract:
Trans-tympanic electric auditory brainstem response (TT-EABR) is an established pre-operative investigation in cochlear implantation surgery. Various techniques have been employed to obtain electrical responses but there has been no universal agreement on the exact positioning of the stimulating electrode on the medial wall of the mesotympanum. The authors investigate the relationship of the positioning of the electrode and the brainstem response.
