Since the cochlear implant surgery was launched in China in the mid-1990s, especially since the “National Rescue Cochlear Implant Rehabilitation Program for Poor Deaf Children” implemented by the China Rehabilitation Center for Deaf Children, several ENT departments of major hospitals have been able to perform cochlear implant surgery and have formulated relevant specifications for cochlear implant surgery. In particular, the cochlear implant centers of some major hospitals have rich experience in cochlear implant surgery, preoperative language assessment and postoperative language rehabilitation. Generally speaking, there is not much difference between these hospitals in terms of purely surgical techniques, and to put it bluntly, parents should know that cochlear implantation is not simply a surgical implant, but should pay more attention to whether the preoperative evaluation is accurate, whether the characteristics of the product are understood, whether the implantation is minimally invasive, whether there will be recent and long-term complications after the surgery, and the ability of the hospital and surgeon to handle and rehabilitate the cochlear implant after surgery. The cochlear implant technology was created and is now being used in many countries. The birth and maturity of cochlear implant technology has brought great changes to the lives of millions of hearing-impaired patients, freeing them from the bad luck of living in a silent world for the rest of their lives and leading them to a world of sound and an infinitely better future! There is no doubt that choosing an experienced surgeon to perform the surgery has a definite impact on the post-operative results, because cochlear implantation is a systematic project, and the successful implantation of electrodes into the cochlea is only part of the success of the cochlear implantation surgery. The success of cochlear implant surgery depends on several factors. 1. comprehensive audiological evaluation; 2. accurate imaging evaluation; 3. solid theoretical knowledge of cochlear implantation and its surgery; 4. rich surgical experience in minimally invasive cochlear implantation; 5. complete operating room and general anesthesia support conditions; 6. systematic postoperative tuning and language rehabilitation treatment. I. Systematic speech and hearing assessment system: At present, we routinely carry out more than ten clinical audiological tests such as pure tone audiometry, acoustic conductance resistance, 40Hz correlation potential, ABR, speech audiometry, multi-frequency steady state, cochlear potential, otoacoustic emission, behavioral audiometry, visual reinforcement audiometry, etc. We can perform preoperative, intraoperative and postoperative systematic audiological tests and assessments for hearing impairment problems in younger children and even newborns. These evaluations are extremely important in determining the site of deafness, the extent of the lesion, and assessing the efficacy of cochlear implant surgery. Second, extensive clinical experience in cochlear implantation surgery: The surgeon should make every case of cochlear implantation as free as possible from serious surgical complications (i.e., complications that require reoperation for revision such as incisional infection, flap necrosis, implant exposure, cerebrospinal fluid leakage, etc.). In addition, it is more important to expand the indications for cochlear implantation, such as some conditions that were previously considered impossible for cochlear implantation (e.g., certain inner ear malformations, severe ossification of the cochlea, etc.), and to be as minimally invasive as possible for routine surgery in order to achieve the best surgical results. In addition, the ability to deal with post-operative complications is required. Thoughtful preoperative services and standardized postoperative follow-up: High-quality and systematic preoperative evaluation, intraoperative monitoring, postoperative tuning, language rehabilitation, and long-term follow-up are closely related to the surgical outcome. Post-operative debugging, pre-operative consultation, intra-operative monitoring, and post-operative tuning and rehabilitation should be done by specialized audiologists who have a more comprehensive understanding of each implant recipient’s situation and who can establish a lifelong personalized medical file and rehabilitation program for each patient, ultimately creating good conditions for the patient’s smooth integration into the world of sound. As a parent or family member, or as a patient yourself, you may experience confusion and pain before choosing a cochlear implant, not only because of the huge medical costs, but also because you are concerned about the results of the surgery. It is also important to consider carefully which hospital and which surgeon to choose for the surgery.
