The effect of surgical complexity on hearing preservation during cochlear implantation with sheathed perimodiolar electrodes Open
Purpose The causes of residual hearing loss during cochlear implantation are generally poorly understood. This study sought to understand whether the complexity of this surgical approach related to a loss of residual hearing. Method Thirty…

Classification of Acoustic Hearing Preservation After Cochlear Implantation Using Electrocochleography Open
The objective to preserve residual hearing during cochlear implantation has recently led to the use of intracochlear electrocochleography (ECochG) as an intraoperative monitoring tool. Currently, a decrease in the amplitude of the differen…

Effect of Proximity to the Modiolus for the Cochlear CI532 Slim Modiolar Electrode Array on Evoked Compound Action Potentials and Programming Levels Open
Background: The first surgeries with CI532 showed an effect of the proximity of the electrode to the modiolus on the Evoked Compound Action Potentials (ECAPs). Objectives: Objectives of the study were to investigate the effect of the “pull…

Fusion of Technology in Cochlear Implantation Surgery: Investigation of Fluoroscopically Assisted Robotic Electrode Insertion Open
The HEARO cochlear implantation surgery aims to replace the conventional wide mastoidectomy approach with a minimally invasive direct cochlear access. The main advantage of the HEARO access would be that the trajectory accommodates the opt…

In Norway, about one out of 2000 babies born is deaf, which means up to 20–30 children are born deaf every year. Some become deaf later due to diseases like meningitis or because of disease during pregnancy. In recent years, in particular,…
