The Austrian cochlear implant has long electrodes (31 mm) that cover the entire length of the cochlea, allowing for a high level of fine sound discrimination during post-operative rehabilitation. The implant is ceramic, which is histocompatible and thin, making it aesthetically pleasing and virtually stress-free on the scalp. However, the conventional Austrian cochlear implantation method uses a large incision (8 cm), and even the minimally invasive approach surgery reported by foreign doctors this year has an incision of 4-5 cm. It has the following characteristics and superiority. 1. The incision is small. For the Austrian cochlea, only a 2.8cm incision is needed to complete the surgery (the length of the incision in conventional surgery is 5-8cm). The small incision greatly reduces bleeding, the number of stitches and the swelling of the incision, and the post-operative scar is minimal. The incision is aesthetically pleasing and almost every parent smiles comfortably after the bandage is removed from their child. 2. The special design of the myofascial bone coat flap with the tip at the posterior side allows complete coverage of the implant and bone surface with three layers of sutures. This design greatly reduces the incidence of scalp edema behind the incision and also greatly reduces the risk of incision infection and implant dislodgement, and the three-layer suture guarantees foolproofness. Patients who have undergone minimally invasive cochlear implant surgery have had no incisional infections, hematomas or implant exposure. The minimally invasive approach to cochlear electrode insertion ensures that valuable residual hearing is preserved and the delicate structures within the cochlea are protected. This approach is essential for patients with residual hearing to have a good postoperative recovery, while for patients without residual hearing, soft electrode implantation or flexible surgical insertion of electrodes can maintain the normal shape of the microstructure in the cochlea as much as possible, thus allowing better coupling between the electrodes and the nerves and neurons in the cochlea to achieve better cochlear hearing outcomes.
