Cochlear

Patients who struggle with severe hearing loss that stops responding to hearing aids should consider a consult with an ENT specialist or an audiologist. Another major sign is struggling to understand speech even with powerful amplification. Signs that a cochlear implant evaluation may be appropriate are also when patients find themselves relying heavily on lip-reading or feeling increasingly isolated in social situations.

For younger children, there are also specific signs. A child who does not startle at loud sounds, does not turn towards sound sources by six months of age or has significant delays in speech and language milestones would need an evaluation. Another reason to seek a professional opinion without delay is a family history of early childhood deafness. The earlier appropriate intervention is received by a child, the better their long-term outcomes for language development.

A comprehensive series of assessments are carried out, to determine whether someone is a suitable candidate for a cochlear implant. This is led by a multidisciplinary team. An ENT surgeon, an audiologist and a speech-language pathologist make up the teams working together. A detailed audiological evaluation is the start. This includes unaided and aided hearing tests to measure the degree of hearing loss and to assess word recognition ability even when using the most powerful hearing aids.

An evaluation of the anatomy of the inner ear and the auditory nerve is conducted. Imaging studies, specifically CT scans or MRI scans are used. These scans help the surgeon plan the procedure while checking for any abnormalities that might affect the surgery or the function of the implant. Additional evaluations are needed for children like assessments of the child's overall development, family support systems and educational placement. To ensure both child and family have realistic expectations and are prepared for the long-term commitment that cochlear implantation require, a psychological evaluation may also be recommended.

• Severe to profound sensorineural hearing loss (bilateral)
• Single-sided deafness
• Failed hearing aid users
• Congenital deafness in infants and children
• Post-lingual hearing loss (hearing loss acquired after learning speech)
• Meningitis-related hearing loss with cochlear ossification
• Otosclerosis with profound sensorineural involvement

The journey at NMC, towards hearing restoration is structured, supportive and deeply personalised. The cochlear implant surgery itself is performed under general anaesthesia and typically lasts between two to four hours. The surgeon makes a small incision behind the ear to access the middle ear. They then carefully insert the electrode array into the cochlea, the internal receiver is then placed under the skin and the incision is closed. Many patients return home on the same day. A brief overnight stay may or may not be required.

The procedure is only one step. About four to six weeks after surgery, once the surgical site has healed is when the true work of hearing begins. This is when the external processor is fitted and activated for the first time. An audiologist then begins the careful process of 'mapping' which is when the device is programmed to suit the individual's unique hearing needs. This is not a one-time event with mapping continuing over successive appointments to fine-tune the settings as the brain learns to interpret the new signals.

The rehabilitation that follows activation is the most critical component of successful cochlear implantation. The brain has to learn how to hear again, or for the first time. Our speech and language therapists work closely with each patient, whether a young child or an older adult. This helps them to develop listening skills, improve speech understanding and build confidence in communication. This is a gradual process and with consistent therapy and support, most recipients achieve remarkable improvements. Their ability to engage in conversation and to connect with those around them improves.

To support patients throughout the financial planning process, NMC offers transparent guidance and works with major insurance providers.

NMC is proud to be home to some of the most experienced cochlear implant surgeons in the region, serving patients across Abu Dhabi, Dubai, Sharjah, Ajman, Ras Al Khaimah and Al Ain. Our team has performed over 1,500 cochlear implant surgeries collectively, in collaboration with the Tarabichi-Mondy Cochlear Implant Center at NMC Royal Hospital Khalifa City, Abu Dhabi. One of our consultant ENT surgeons has performed the highest number of cochlear implant surgeries by a single surgeon in the UAE. 126 procedures were completed in a single centre between 2021 and 2023 alone by our surgeons.

Our team includes dedicated audiologists who conduct thorough pre-operative evaluations and manage the intricate post-operative programming. Our speech-language pathologists provide ongoing rehabilitation, which is essential for achieving the best possible outcomes. Patients will find a team that listens, explains clearly, and is committed to their hearing journey. From the first consultation through every stage of mapping and therapy, the team supports patients.
