摘要: The effects of cochlear implants on residual hearing loss is investigated through a finite element model human auditory periphery consisting the cochlea and middle ear. simulation results show that round window stiffness dominant factor in loss. increased to five times caused over 4 dB at low frequencies below 500 Hz. Without considering ossification, inserting implant can most difference magnitude from no-implant case although implant's geometry position has been varied. If same, suggest use thin-straight-cochlear inserted into lateral side order preserve 700 Hz. In addition, when distance between basilar membrane closer, becomes severe high above 1 kHz. would be helpful for choice depending patient's condition.
