Eligibility Criteria

Cochlear implants are an effective treatment option for individuals with severe to profound GJB2 hearing loss who do not benefit from hearing aids. Eligibility for cochlear implants is determined through a comprehensive evaluation process, which includes audiological assessments, medical examinations, and imaging studies. Candidates should have a strong support system and be committed to the follow-up care required after the implantation.

Surgical Procedure

The cochlear implant procedure involves surgically inserting an electrode array into the cochlea and placing a receiver-stimulator under the skin behind the ear. The surgery is typically performed under general anesthesia and takes a few hours. Post-surgery, the external components of the implant, including the microphone and speech processor, are fitted and programmed to suit the individual’s specific hearing needs.

Post-Implant Care and Maintenance

After cochlear implantation, ongoing care and maintenance are essential for optimal functioning. This includes regular follow-up visits with an audiologist for device programming and adjustments. Additionally, speech and auditory training are crucial to help the individual adapt to the new sounds and improve their communication skills. Proper care of the external components, such as cleaning and battery management, is also necessary to ensure the device's longevity.

Speech and Language Therapy

Importance for Children

Speech and language therapy is a vital component of treatment for children with GJB2 hearing loss. Early intervention can significantly enhance language development and communication skills. Therapy focuses on improving speech perception, production, and language comprehension. It is essential to start therapy as soon as possible to maximize the child’s potential for developing strong communication abilities.

Techniques Used in Therapy

Various techniques are employed in speech and language therapy to address the unique needs of each child. These may include auditory-verbal therapy, which emphasizes listening and spoken language, and total communication, which incorporates sign language and other visual aids.
