The answer is no. Minimally invasive electrode implantation should be chosen for any cochlear implant surgery: 1. Minimally invasive electrode approaches such as the round window membrane approach (for the Austrian MED-EL cochlea) and the subcochlear window approach (for the Australian Cochlear cochlea) will ensure that electrode implantation enters the tympanic level, and a large number of studies have shown that electrode implantation in the cochlea is essential for good results in postoperative hearing assistance. In contrast, the percentage of electrodes that penetrate the basilar membrane in the cochlea and enter the vestibular level is as high as 30-50% in conventional implantation methods. 2. Minimally invasive electrode implantation does not damage the internal structures of the cochlea and provides excellent protection for the cochlear bone spiral plate, cochlear shaft, nerve fibers and spiral ganglion. With fine operation and medication, the residual hearing can be preserved to the maximum, while the maximum preservation of the cochlear structures can provide room for reimplantation or more advanced treatment methods in the future. 3. Children sometimes have a process of auditory development, and their hearing at the time of implantation may improve with age and neurological maturation, so it is especially important to perform surgery to preserve residual hearing for each child at this time.
