After cochlear implantation, auditory rehab and speech rehab are required to aid in recovery. Auditory rehabilitation training is based on cochlear implantation and long-term planned sound stimulation to help patients gradually develop their listening habits and improve their auditory-related abilities, including hearing perception, auditory attention, auditory localization and recognition, and memory. Speech rehabilitation training is based on the principle of complementary auditory, visual and tactile functions. Through audio indicators and other instruments, patients are scientifically trained to vocalize and lip-reading abilities, so that they can understand and accumulate vocabulary, master grammatical rules and express themselves. Auditory-verbal rehabilitation is very important and should be carried out under the guidance of a professional physician. If there is any discomfort, it is recommended to consult a doctor in time.
