At the International Polizter Ear Congress held in Athens, Greece, from September 27 to October 1, 2011, research and clinical application of minimally invasive cochlear implantation became a hot topic. A large number of foreign studies have shown that minimally invasive implantation of cochlear electrodes (soft electrodes, soft surgery) can preserve residual hearing with great certainty, protect the structures and nerve fibers within the cochlea, and can ensure more desirable results of cochlear implantation ( Even in patients with no residual hearing), especially in the area of sound recognition and sound localization in noisy environments, these new academic ideas and data have attracted the attention and resonance of participating doctors from various countries. Prof. Park Dai of the General Hospital of the Chinese People’s Liberation Army reported on the results of 180 minimally invasive cochlear implant surgeries, minimally invasive small incision cochlear implant surgeries and intraoperative CT-guided difficult cochlear implant surgeries, in which a group of cochlear patients with near-normal low-frequency hearing (extremely poor high-frequency hearing and preoperative speech recognition not meeting the needs) were operated with minimally invasive electrodes in this congress. In one group of patients with near-normal low-frequency hearing (very poor high-frequency hearing and preoperative speech recognition that was not adequate), 100% of their postoperative hearing was preserved and their postoperative preoperative hearing was essentially the same. This was the first time that Chinese doctors reported on cochlear implantation with residual hearing preservation at an international conference, and it was well received and appreciated by international colleagues. Prof. Park Dai also participated in a roundtable discussion on cochlear implantation, discussing with five internationally renowned professors the strategic decision of difficult cochlear implantation. ProfPaul from Belgium said he was jealous of the Chinese doctors for having such good surgical conditions. The conference announced the advent of minimally invasive cochlear implantation. Cochlear implantation is no longer a routine surgery where the electrodes are simply placed into the cochlea, but a refined surgery that focuses on reducing trauma, bleeding and post-operative scarring; non-invasive or minimally invasive implantation of electrodes; and preservation of residual hearing and the normal shape of structures in the cochlea as much as possible.
