In vitro modifications of the scala tympani environment and the cochlear implant array surface

The Laryngoscope, 06/04/2012

Modifications of the scala tympani's environment with 50% to 75% alginate/barium chloride and of the cochlear implant electrode surface with neurotrophic factor–producing fibroblasts drastically reduce the insertion forces. As both modifications may serve future intracochlear therapies, it is expected that these might additionally reduce possible insertion trauma.
