It has been nearly 20 years since the introduction of multiconductor cochlear implants into China. The scope of indications, surgical techniques, and the application of new coding technologies have gradually converged with the international mainstream and have reached international standards, with considerable academic achievements. In terms of indications, the early indications for cochlear implants were extremely severe sensorineural deafness of 90 dB or more in both ears. With the deepening of the understanding of the rehabilitation effect of cochlear implants and the advancement of technology, the range of indications for cochlear implants has been greatly expanded. According to statistics, patients with severe deafness (hearing loss between 70 dB and 90 dB) who have poor rehabilitation results with optimal hearing assistance abroad have achieved good residual hearing preservation and speech recognition after cochlear implantation. In addition, patients with unilateral deafness have achieved very good satisfaction with cochlear implantation to improve their quality of life. With the development of combined acoustic and electrical stimulation (hearing aid + cochlear implant), patients with partial deafness have also achieved good hearing gain with cochlear implants. In terms of surgical technique, residual hearing preservation is the mainstream concept and trend of cochlear implantation at present and even in the next decade. At present, there are nearly 10 surgeons in China who can perform minimally invasive surgery, round window implantation, and residual hearing preservation techniques to international standards. However, it is still dominated by doctors from top major hospitals. This concept and technology is now widely recognized by the industry, and it is believed that the country will make greater achievements in surgical techniques in the future. In terms of sound coding technology applications, prior to 2009, the mainstream cochlear implants of all kinds used traditional sound envelope coding (amplitude extraction). However, this strategy neglected the low-frequency fine structure of the sound, so it was unfortunate for speech recognition in noise, Chinese vocal tones, and music appreciation. After the introduction of the new encoding strategy (fine structure processing) in 2009, a comparative study conducted by major hospitals in China confirmed that the new encoding strategy could indeed compensate for these shortcomings and was published internationally.
