We know that any surgery is at risk, and cochlear implant surgery is a type of surgery, and of course there are also surgical risks. There are many large and small hospitals in China that are doing cochlear implant surgery. In comparison, there is no obvious gap in technology. We recommend that overseas medical implants have cochlear implants, not only because their products are newer, but also at lower prices. More consideration is that their surgical techniques are more mature and their relative recovery is better.

Cochlear implant surgery is not only the operation of the ear, but also the operation of facial nerve. The most common cause of postoperative complications is the damage of facial nerve, which can cause facial paralysis and other symptoms. Currently, 100 children undergo surgery. There are about 7 children who have this kind of situation. Because the electrode of the cochlear implant is like a cable, the cable is inserted into the child’s inner ear cochlea through the facial nerve crypt, and on the way the cable passes, the facial nerve is around the facial nerve crypt, if the electrode and When the facial nerve is approaching or touching, after the cochlear is powered on, the current of the electrode will stimulate the facial nerve, which may cause damage to the facial nerve of the child, which may cause facial paralysis. If such a situation occurs clinically, the general solution is to re-implant, avoiding the facial nerve and other nerve sites to implant the electrode. In overseas surgery, “neural detection technology” is generally used to detect facial nerves hidden in bones and to mark them during surgery, so that important nerves can be avoided and postoperative facial nerve damage can be prevented.

Postoperative wound length and wound management are also effective ways to prevent postoperative complications. Surgical wounds are prone to postoperative skin flap necrosis, infection and other symptoms. The current proportion of such cases is 2%~5%. It is the second major complication of cochlear surgery. Due to the large incision during the operation, the susceptible area is large, and the redness, cracking, and even the implantation of the skin are more likely to occur after surgery, which may cause intracranial infection, and the consequences are unimaginable. If this happens, we recommend clinically removing the infected implant and re-implanting it. Outside the wound, it is generally controlled around 2.5cm, which can basically eliminate such complications, and uses self-ablative sutures to heal the wound naturally without dismantling.

Most children who need to implant a cochlear implant are relatively more likely to have hearing, but patients with full sputum are rare. That is to say, although the hearing loss is serious, the hair cells in the cochlea are more or less reserved. The hair cells retained in these cochleas reflect the child’s residual hearing. Currently, residual hearing is generally associated with two factors, surgical techniques and products for cochlear implants. The softer the electrode part of the implant, the protective effect on the residual cochlear hair cells, while the focus on retaining residual hearing is of course the surgical technique of the surgeon. At present, the residual hearing success rate in the territory is basically around 50%, and because of the gap in medical level abroad, the residual hearing success rate after surgery is generally 80% to 90%. Do your best to ensure the integrity of your child’s cochlea.

In addition to the above three types of most common complications, complications of cochlear implants include anesthesia allergy, silicone allergy, intracranial infection, etc., but it is not common in clinical practice. Anesthesia allergy is a probability of one in a million, but if this happens, the consequences are more serious. More anti-allergic drugs are prepared in overseas hospitals. In the event of an emergency, tragedies can be avoided. The incidence of silicone allergies and intracranial infections is less than 2%. This complication is not only the pros and cons of surgical techniques, but also depends on the materials and technology of cochlear implants. The thinner the implant, the less wear can be made to the patient’s skull during surgery, protecting the integrity of the skull and reducing the chance of intracranial infection.

Any surgery is risky, but the risk of overseas surgery is less than the risk in the country. After the cochlear implant, if the implant is not damaged, it is used for life, so you can imagine it. importance. Therefore, it is the responsibility of the child to choose the surgery with better surgery technology and less risk, and it is also responsible for the future of the child!
