Intracochlear insertion of electrodes using hyaluronic acid in cochlear implant surgery

Article specifications

This clinical study was published in 2006 in The Journal of Laryngology & Otology (IF2015: 0.44) by German and Israeli Otolaryngologists.  The Otorhinolaryngologists describe a method which included coating the electrodes with a thin layer of hyaluronic acid as well as using a droplet of the lubricant on the cochleostomy to provide additional magnification, like a lens, that facilitates the insertion of the electrode array. Then evaluated the safety and efficacy of the new method.

Results

Results of the study showed that the use of hyaluronic acid reduces trauma to the cochlea and avoids contaminating perilymph by blood or by saline used during the operation. It is an efficacious and reliable method for cochlear implant surgery.
