Cochlear Implants: A lifeline for hearing loss

In a world that thrives on sound, silence can be isolating, especially for those born with profound hearing loss. Shockingly, the World Health Organisation reports that 1 in 5 people globally live with hearing loss, a statistic expected to rise to 1 in 4 by 2050.

However, modern medical technology offers hope and transformation through Cochlear Implants. Dr. Shailendra Sivalingam, Consultant Otorhinolaryngology (ENT), Otology, Neurotology, Head & Neck and Skull Base Surgery at Sunway Medical Centre shares insights into cochlear implants, early intervention, their life-changing potential, and the support networks vital for patients and families on this journey to regain hearing.

A life-changing solution

Cochlear implants hold the power to turn the world of sound from an elusive dream into a vibrant reality for individuals, both children and adults, grappling with hearing loss. Dr. Shailendra explains these remarkable devices, stating,

“Cochlear implants comprise an internal device with electrodes implanted into the cochlea and an external device that captures and transmits sound to the implant. This ingenious technology bypasses damaged cochleae, converting sound into electrical signals that stimulate the auditory nerve, enabling individuals to perceive sound.”

Crucially, cochlear implants offer the most significant benefit when implemented in infancy or early childhood. Studies reveal that cochlear implantation before age 5 can profoundly impact a child’s auditory development, equipping them with lifelong advantages2,3.

Dr. Shailendra underscores the urgency of early intervention, as a child’s ability to learn and comprehend speech rapidly diminishes after age four to five. Implantation before this critical threshold empowers them to attain educational and social milestones on par with their hearing peers.

The journey of hope

The journey from cochlear implant surgery to recovery and therapy may be arduous, but its positive impact endures a lifetime. Patients and their families can seek guidance and support from therapists at the speech and hearing centre right from the initial diagnosis of hearing loss through the selection of appropriate hearing aids for children before cochlear implantation and during the recovery process.

Dr. Shailendra highlights the pivotal roles of audiologists and speech therapists in a patient’s recovery and therapy journey. He explains, “After the surgical implantation, patients commence a vital mapping process with an audiologist. Over 6 to 8 months, therapists fine-tune the cochlear implant settings, optimising hearing and speech capabilities. For children, this ongoing mapping ensures continuous improvement, especially as they grow.”

Dr. Shailendra shares the inspiring story of a young lady in her 30s who, following her cochlear implant surgery, experienced a swift recovery. She can now partake in activities she could not enjoy before, such as hiking and trail running. Her journey stands as a testament to the life-changing potential of cochlear implants, offering hope and inspiration to others facing the same decision.

Cochlear implants represent not just a technological marvel but a lifeline for those battling hearing loss. Dr. Shailendra Sivalingam’s insights shed light on the profound impact of these devices, particularly when embraced at a young age. Early intervention holds the key to unlocking a world of sound and enabling individuals to navigate life’s auditory intricacies.

The journey from diagnosis to cochlear implantation may be a challenging one, but the rewards endure for a lifetime. The support of therapists, audiologists, and speech therapists plays an instrumental role in this transformative process. Through their guidance and expertise, individuals can regain the precious gift of hearing.
