Cochlear implantation has been a blessing to countless families, but the patient’s road to recovery has just begun. What is a cochlear implant? A cochlear implant is an electronic device that replaces damaged cochlear hair cells and, through the passage of an electric current, the auditory nerve regains access to sound signals. Why is hearing and speech rehabilitation necessary after cochlear implantation for deaf children? A cochlear implant does not mean that a child will be able to hear and speak. Due to the lack of sound environment and speech stimulation for prelingually deaf children, after the cochlear implant is switched on, the hearing age of the child is only 0 years old, and the child is only able to perceive sounds, and the auditory-verbal system is just being established at this time. Therefore, the cochlear implanted child must undergo scientific auditory-verbal rehabilitation training after he/she becomes aware of sound. Through scientific and effective auditory-verbal rehabilitation training, we can build up and perfect their perceptual, discriminative and comprehension listening abilities, and promote the development of their speech comprehension, speech expression and language utilization abilities. Do children with cochlear implants have other problems besides hearing and speech dysfunction? Due to the lack of sound stimulation in the early stages of prelingual deafness, most children with hearing and speech impairments have delayed motor development (gross and fine motor) and impaired balance. In addition to this, children may also have perceptual deficits, personal-social deficits and cognitive deficits. This is related to the child’s family and surroundings, and especially to the lack of self-confidence due to hearing and speech impairments. How long does it take for a deaf child to start rehabilitation after cochlear implantation? The child needs to be switched on and debugged after the surgery, usually 1 to 4 weeks after the surgery, and 1 to 2 times in the first month after the surgery. After the child is switched on and debugged normally, as well as through the regular medical institutions. After comprehensive evaluation, rehabilitation training can start if there are no other contraindications for rehabilitation. What kind of rehabilitation assessment is needed before the post-cochlear implantation rehabilitation training for deaf children? Audiological assessment: including the Meaningful Auditory Integration Scale (MAIS), the Criteria for Auditory Behavioral Classification (CAP), and the Speech Intelligibility Rating (SIR), etc., to find out the improvement of the child’s hearing and speech after hearing reconstruction. Rehabilitation assessment: Auditory, speech and language ability assessment and motor development and balance function assessment: to understand the rehabilitation effect, determine the starting point of training, clarify the rehabilitation development goals, and guide the formulation of rehabilitation programs. Questionnaire assessment: such as child and parent anxiety scale, etc., to assess the impact of the psychological condition of the child and parents on the child’s recovery. Therefore, a comprehensive assessment should be conducted in a formal medical institution before rehabilitation training, including audiological examination of the child, hearing and speech ability, motor development and balance function assessment, etc. At the same time, the bone strength and growth development of the child should be detected during the rehabilitation training, so as to more comprehensively promote the functional recovery of the child, to improve the quality of life, and to return to school. How to choose the rehabilitation mode after cochlear implantation? Should it be rehabilitation in a medical institution or community-based family rehabilitation? At present, at home and abroad, the combination of medical rehabilitation and educational rehabilitation is the dominant mode of postoperative rehabilitation for children with cochlear implants. Institutional medical rehabilitation: children can receive full-time pre-school rehabilitation education, auditory management and individual intensive training in rehabilitation institutions for auditory-verbal rehabilitation. Community-based family rehabilitation: Children with cochlear implants at a younger age can choose to be guided by the institution, and adopt the forms of parent-child training, single training by appointment and family guidance time service to implement auditory-verbal rehabilitation training. Class attendance: Children with certain auditory-verbal ability are encouraged to attend ordinary kindergartens and schools. Therefore, after cochlear implantation, every child needs to have regular normal commissioning and evaluation of the cochlear implant in the relevant department of the original surgical hospital, and then go to a regular medical rehabilitation institution for rehabilitation evaluation, and make choices according to the doctor’s evaluation results and recommendations. Families with conditions can choose the mode of “medical rehabilitation + family rehabilitation + special education rehabilitation” for comprehensive rehabilitation treatment. Families with limited resources can choose a model that combines family rehabilitation with medical rehabilitation or special education rehabilitation. Full-time or day-care rehabilitation? There are advantages and disadvantages to both full-time and day-care rehabilitation, but for the time being, it is recommended that parents choose day-care rehabilitation due to a number of factors. On the one hand, full-time rehabilitation is more expensive for parents, which puts a certain amount of financial pressure on the family, and the parents’ time with their children is shortened, which may bring negative psychological and emotional effects on the children, and affect their cognitive and personal-social abilities. On the other hand, day care rehabilitation emphasizes parent-child classes, parent-child activities and interaction between parents and children in daily life, and provides more loving care and guidance to children in the process of recovery. Therefore, it is recommended that parents choose the mode of combining “family rehabilitation+medical day care rehabilitation+special education rehabilitation” in which the children, parents and teachers can organically combine to achieve better results. Only through the organic combination of children, parents and teachers can we better promote the healthy development of the whole body and mind of the children. What are the daily safety precautions after cochlear implant surgery? First, avoid strenuous sports that involve direct physical contact, such as basketball. For sports that do not involve direct body contact, such as running, remove the external wires and speech processor or hide them under clothing. For most water sports, remove the external cord and language processor. Secondly, in thunderstorms and when taking off and landing in airplanes, the cables and processor should also be removed to avoid damage to the cochlear implant. What should parents do in the home rehabilitation of a child with a cochlear implant? Parents are the first and lifelong teachers of their children. The psychological state of the parents, their relationship with their children, their parenting style, their involvement in their children’s rehabilitation, their expectations of their children, and the amount of rehabilitation knowledge and skills they understand and have acquired can all have a direct impact on the outcome of their children’s rehabilitation. Therefore, parents should create a good family environment for their children, teach their children basic life knowledge and skills, cultivate their children’s physical and mental health, let their children have good behavioral habits, and develop their intelligence and interests. Secondly, parents should also learn how to use natural sounds and various family activities at home to develop their children’s “listening” and “speaking”.
