What are the advantages of bilateral cochlear implants? 1. It conforms to normal auditory physiology and can produce stereo hearing. 2.Improves speech recognition, especially in noisy environments or complex environments where multiple people are talking. 3.Improve the overall hearing threshold, bilateral compared to unilateral average hearing increased by 5-10 decibels, speech recognition rate increased by more than 30%. 4.Improve the ability to orient and localize sound. 5.It is good for auditory balance, more in line with the development of human balance. 6.Ensure the activation and development of bilateral auditory pathways and auditory centers, and behavior, intelligence, emotion and socialization are better than unilateral. How should I choose the time for bilateral cochlear implant surgery? 1. Simultaneous surgery: For patients who have the conditions, it is recommended to have bilateral cochlear implants at the same time, with one anesthetic and one surgery. 2. Staged surgery: It is best to have bilateral cochlear implants at an interval of less than 6 months. Too long an interval will result in hearing deprivation and a shift in the dominant side of hearing, and the adaptation time is relatively longer.
