The traditional surgical route for cochlear implantation is the facial saphenous-capsule approach, in which the cochlear implantation electrode is inserted through a window in the capsule of the cochlea. In recent years, cochlear electrode technology has improved and the electrode design has become more flexible, making cochlear implantation from the cochlear round window a reality, making cochlear implantation as minimally invasive as nasal endoscopy: less damage, more accurate implantation, and more guaranteed results. The advantages of cochlear implantation: 1. The cochlear window is not opened on the cochlea itself, which protects the cochlea from damage to its own structure and makes it possible for patients to enjoy future technologies such as medication, cellular gene therapy or newer technologies. 4. Using special electrodes such as soft electrodes and super soft electrodes, the cochlea is implanted with soft technology, which does not damage the microstructure of the cochlea or the residual hearing. 5. The round window implantation ensures the accurate implantation of electrodes into the cochlea, which avoids the mistake of implanting the window in the tympanic capsule, and the postoperative hearing effect is more guaranteed. Cochlear implantation with a round window has become the mainstream trend of cochlear implantation, and a large number of clinical reports have confirmed that minimally invasive cochlear implantation with a round window in children, especially young children, is more secure for the child’s recovery and future, and parents of deaf children are welcome to visit our hospital for treatment.
