Hifocus Helixâ„¢ Electrode Insertion: Surgical Approach.
Cochlear implants have been used for almost 30 years as a device for the rehabilitation of individuals with severe-to-profound hearing loss. One of the important aspects of cochlear implantation is the type of electrode selected and proper insertion of the electrode array in scala tympani to minimize cochlear damage. The HiFocus Helixâ„¢ electrode is a precurved design aimed at placing the electrode contacts close to the spiral ganglion cells in the modiolus. The prescribed insertion techniques are intended to minimize the likelihood of damage to the basilar membrane or lateral wall of the cochlea. To describe the first insertion of a HiFocus Helixâ„¢ electrode in Brazil exposing surgical particularities and device details in a patient with profound hearing loss, due to Mondini's dysplasia. No problems were encountered during the surgical procedure. The patient experienced improvement in hearing thresholds and speech perception. The HiFocus Helixâ„¢ electrode proved easy to insert and provided expected hearing benefits for the patient. This manuscript indicates that the HiResolutionâ„¢ Bionic Ear System with HiFocus Helixâ„¢ electrode comprise a cochlear implant system that is practical and beneficial for the treatment of severe-to-profound hearing loss.830
