γγThe advantages of bilateral cochlear implants are as follows: 1. Bilateral cochlear implants, especially simultaneous bilateral implants, can significantly improve speech comprehension, especially in noisy environments 2. Bilateral hearing and speaking allows for a significant increase in auditory loudness 3. It allows the implant recipient to have sound localization capabilities, which is very important for increasing speech recognition in multiple simultaneous conversations 4. The cost will be greatly reduced, and only one hospitalization, one surgery, and one side of the anesthesia can complete the implantation of both sides.γγ5. The current minimally invasive and residual hearing preserving surgical approach makes bilateral implantation more feasible and reliable. Studies have shown that the performance of bilateral cochlear implant recipients two years after surgery is equivalent to that of unilateral cochlear implant recipients three years after surgery, indicating that bilateral implantation progresses more quickly, while minimally invasive implantation that preserves the structural integrity of the cochlea does not affect the expectation of new technologies and approaches in the future.
