How to Support Children Who Receive a Cochlear Implant Late
Children who receive cochlear implants late are unique. This article briefly describes hearing loss diagnosis and treatment guidelines for babies and young children, what is known about why some children are diagnosed or treated later as well as the impacts of unaddressed hearing loss. After that, we provide some rehabilitation recommendations for supporting this unique population of patients with cochlear implants.
Early intervention is seen as the gold standard for children with hearing loss whose families wish for them to develop spoken language. In ideal situations, intervention should begin as soon as possible after diagnosis. The US Centers for Disease Control has issued 1-3-6 guidelines, recommending hearing loss screenings before 1 month of age, evaluations before 3 months of age, and intervention before 6 months of age.[1]
Age at implantation is a crucial predictor of benefit from cochlear implants,[2] and it is one of the main factors that affects communication outcomes in pediatric cochlear implant patients. There is clear evidence that the best outcomes are found in children who were diagnosed early, fitted with appropriate state-of-the-art technology, and then received good quality intervention based around the development of spoken language.[3]
“Early intervention is crucial to minimize the adverse impact of hearing loss on language and cognitive development.”
Despite clear evidence and expert recommendations for early intervention, a substantial number of children still experience late confirmation and intervention, especially infants that present with developmental or medical issues as well as middle ear disorders.[4]
Additionally, the prevalence of late-onset hearing loss sometimes due to congenital infection from cytomegalovirus (cCMV) or genetic disorders,[5] and children missing newborn hearing screenings have led some experts and the World Health Organization to advocate for pre-school hearing screenings for comprehensive detection of hearing loss in early childhood.[6][7]
The Effects of Late Treatment of Hearing Loss in Children
Research has shown that children who do not receive timely diagnosis and hearing loss treatment may experience:
- Delayed speech and language development compared to those who were implanted earlier [8]
- Delayed social development and weaker academic performance [9]
- Limited concentration spans and behavior that is sometimes difficult to manage [10]
- Widespread degeneration in the central auditory system if profound SNHL remains untreated due to prolonged auditory deprivation [3, 11, 12]
For more on the effects of late diagnosis and treatment, Section 1.4 of the World Health Organization’s World Report on Hearing summarizes the impact of unaddressed hearing loss.[7]
Special Characteristics of Children Who Receive Cochlear Implants Late
When beginning rehabilitation after cochlear implantation, children who receive hearing loss treatment later tend to exhibit some characteristics that can be advantageous when developing their individualized rehabilitation program. This is because late-implanted children have typically gained more experience at social events and practicing other skills than their peers who are younger and were implanted earlier.
For instance, they have had the chance to attend many birthday parties, celebrations, and excursions. As a result, their non-verbal cognitive skills may be more developed than those of younger children treated earlier. In addition, their motor skills may be more advanced, so they can be involved in activities such as cutting and drawing. They may have developed some skills in literacy, such as recognizing or writing letters.
Steps to Support Pediatric Patients in Late Cochlear Implantation
Just like children implanted earlier, those implanted later need to go step by step through the stages of auditory development. Remember that those stages may be slower than those of children implanted earlier. To track overall development, MED-EL’s A Child’s Journey Developmental Milestones (Birth – 6 Years) may be useful.
- Step One: Assessment
Assess the child’s current level of function. Some children who receive their implant later may have already developed some listening and spoken language abilities; others will be newly beginning this process. It is also useful to assess the child’s non-verbal communication such as the presence or absence of joint attention, gesture, eye contact, etc.
- Step Two: Beginning With Listening
Identify appropriate goals. Begin with detection of sound, then move through stages of discrimination, identification, and comprehension. For children implanted late, it is important to spend a significant amount of time on the detection of sound as this does not come as naturally as it does for children implanted earlier.
For developing discrimination and identification skills, play sounds are useful. For some ideas and a resource to help with this, check out Play Sounds: A Gateway to Listening and Language Development. As children move into the comprehension stage, focus on a range of short everyday phrases that they will hear during a routine day such as “bye-bye,” “up, up,” and “sit down.”
- Step Three: Beginning With Spoken Language
Identify appropriate goals. As this group of children is older when they begin the process, work on early spoken language goals concurrently with listening goals. All activities for listening development can be used with ”role reversal” to encourage spoken language. In role reversal, the child takes a turn at saying the sound or phrase that is being targeted.
Begin with words and phrases that are meaningful and useful for the child. Their name, their family members’ and pets’ names as well as names of favorite toys and foods are good places to start. Target words, which can be used in many situations and can help the child functionally, are great words to start with. In English, for example, we might first target “more,” “please,” “no,” “don’t,” “me,” and “mine.” After that, you can continue with Vocabulary Building Tips for Every Stage of Your Child’s Development.
Additional Considerations for Late Pediatric Recipients of Cochlear Implants
Lack of auditory experience in children who are implanted late means that the team responsible for fitting needs to be mindful of certain factors. One is that the child may be overwhelmed by the new sensations of sound. Second, it is crucial, however, that the child wears their processor all waking hours as soon as possible.
While we want to ensure that the child is comfortable wearing the device, we also want to ensure that as soon as possible, they have good access to sound. The aim is for the child to enjoy the full range of sounds that can be provided by the implant system within the first three months following implantation.
Children Benefit Even When Receiving a Cochlear Implant Late
While age at implantation is a significant factor in the potential benefit following cochlear implantation, children who receive a cochlear implant late can still experience an improved quality of life. An intensive, step-by-step approach to rehabilitation that addresses both listening and spoken language goals leads to the optimal success for each individual.
