Although foreign equipment and technology are ahead of domestic ones, there are the most cases of cochlear implant surgery in China. And at present, the smallest cochlear implant in China is 6 months old. At the same time, many hospitals in China already have very mature cochlear implant technology, and the experts are experts with many years of surgical experience, and their clinical experience is quite rich. Statistics show that the failure rate of cochlear implantation in foreign countries is about 5%, while in China it is only 2%-3%.
Others are worried about complications. In fact, responsibly speaking, any operation has complications. The same is true of cochlear implant, but the complications of the operation are closely related to the operation, such as whether the implantation is smooth, the depth and position of electrode implantation, etc. However, with the maturity and perfection of technology, the complications of cochlear implant are few, mainly concentrated in these aspects: the wound is not easy to heal or form hematoma after operation; Facial paralysis, the incidence rate is only 2%, and most of them are transient, which can be recovered by conservative treatment; Non-auditory stimulation, including facial nerve stimulation, pain, vestibular spinous nerve reflex, etc. Dislocation or folding of electrodes requires reoperation and implantation; The implant is broken and needs to be replaced.
However, in order to make the operation go smoothly and avoid even one in ten thousand complications, some cochlear implant brands have also developed technologies that are convenient for doctors to operate during the operation and ensure the safety of the operation. For example, the floating MS electrode in the middle of the cochlea in the United States has patented technology of automatic pole feeding and core stopping, which provides doctors with a better surgical field of vision during implantation, helps doctors accurately control the insertion angle and speed of the electrode, ensures the structural integrity of the cochlea, improves the surgical efficiency and ensures safety. Therefore, in terms of surgical safety, we really don't have to worry, just leave it to the doctor.
There are still many people who are full of imagination about cochlear implant surgery. Some people think it's as simple as outpatient surgery, others think it's a horrible thing, even craniotomy!
The whole craniotomy was a complete misunderstanding. We know that cochlear implants are divided into implanted parts and in vitro parts, and the implanted parts are composed of electrodes and implants. The implant part needs to be inserted into the cochlea by surgery, and the implant is placed under the skin behind the ear and fixed outside the skull, not craniotomy.
However, the operation is not a minimally invasive operation, which takes about 2-3 hours, and the postoperative wound healing takes 7- 10 days. After a month of wound healing, external machines can be installed and debugged, followed by long listening and language rehabilitation training, machine adjustment, retraining and machine adjustment. ...
