| Research Abstract |
Continuous otorrehea and aural atresia prevent the usage of conventional hearing aids. If cartilage conduction was utilizing for hearing aids, it would be applied instead of conventional hearing aids. In the current research, we assessed the benefits of hearing aids utilizing cartilage conduction and elucidated the sound transmission in not only normal anatomical ears but also the ears with aural atresia. In the results, the developed hearing aid provided a great benefit to the above-mentioned patients. With regard to the transmission pathway, cartilage conduction cannot be classified into air or bone conduction. Cartilage-air conduction dominates the sound transmission. Furthermore, in some ears with aural atresia, the forth pathway (fibrotic tissue pathway) is involved in cartilage conduction. This pathway efficiently transmits sounds to the cochlea. In such cases, cartilage conduction hearing aids will show a great benefit.
