Damage to inner ear structure during cochlear implantation: Correlation between insertion force and radio-histological findings in temporal bone specimens
Twelve human cadaveric temporal bones were cochlear implanted at constant speed of insertion. Insertion forces during cochlear implantation were correlated with inner ear structure traumatism. Two different functions were identified for traumatic and atraumatic insertions. The control of the insertion force could reduce the risk of insertion-related damage.
