Advanced Hearing Restoration by Dr. Arindam Das — Consultant Otologist & Cochlear Implant Surgeon
Cochlear and Hearing Implants are revolutionary medical devices that restore hearing in individuals with severe to profound hearing loss who no longer benefit from conventional hearing aids. These advanced solutions help both children and adults reconnect with sounds, speech, and the world around them — improving communication, confidence, and overall quality of life.
Under the expert care of Dr. Arindam Das, one of the best Cochlear Implant Surgeons in South Kolkata, patients receive comprehensive evaluation, precise surgical expertise, and holistic auditory rehabilitation using world-class technology and compassionate care.
Understanding Cochlear & Hearing Implants
The ear converts sound waves into electrical signals that are interpreted by the brain. In cases of sensorineural hearing loss, the inner ear (cochlea) or auditory nerve is damaged, making it difficult or impossible to hear sounds even with hearing aids.
Cochlear and other implantable hearing devices bypass the damaged parts of the ear and directly stimulate the auditory nerve, enabling patients to perceive sound clearly.
Types of Hearing Implants
Cochlear Implants – For patients with severe to profound sensorineural hearing loss in one or both ears.
Bone Anchored Hearing Aids (BAHA) – Suitable for conductive or mixed hearing loss and single-sided deafness.
Middle Ear Implants – Used when hearing aids are not tolerated due to chronic infections or anatomical issues.
Auditory Brainstem Implants (ABI) – For rare cases where the auditory nerve itself is damaged (e.g., neurofibromatosis type 2).
Who Can Benefit from Cochlear or Hearing Implants?
Patients who may benefit include:
Adults or children with moderate to profound sensorineural hearing loss
Individuals who gain little benefit from hearing aids
Post-lingual hearing loss patients (those who lost hearing after learning speech)
Children with congenital or early childhood hearing loss
People with chronic ear conditions preventing use of traditional hearing aids
Early diagnosis and timely intervention — especially in children — are vital for speech, language, and social development.
Common Signs of Severe Hearing Loss
Difficulty understanding speech, especially in noisy environments
Turning up the TV or phone volume excessively
Frequently asking others to repeat themselves
Relying on lip-reading or visual cues to follow conversations
Avoiding social interactions due to hearing challenges
In children: delayed speech or lack of response to sounds
If these symptoms persist, an audiological evaluation by an ENT specialist or otologist is highly recommended.
Diagnostic & Pre-Implant Evaluation
Dr. Arindam Das ensures a thorough evaluation process using state-of-the-art diagnostic tools to determine the most appropriate hearing restoration option.
Comprehensive Diagnostic Steps Include:
Pure Tone Audiometry (PTA) – To measure hearing thresholds.
Speech Audiometry – To evaluate speech discrimination ability.
Tympanometry – To assess middle ear function.
Otoacoustic Emission (OAE) & Auditory Brainstem Response (ABR) – Especially for children or difficult-to-test patients.
CT / MRI Scans – To evaluate cochlear and nerve anatomy.
Multidisciplinary Assessment – Includes audiologist, speech therapist, and psychologist for holistic pre-surgical counseling.
Cochlear Implant Surgery & Rehabilitation
Cochlear Implant Surgery is performed under general anesthesia and typically takes 1–2 hours. Using microscopic and minimally invasive techniques, the implant is placed within the cochlea and connected to an external sound processor.
Post-Surgical Rehabilitation Includes:
Activation of the implant after healing (usually 2–4 weeks post-surgery)
Speech and auditory training for adaptation
Regular follow-up and fine-tuning of the implant for optimal performance
Dr. Arindam Das and his team provide comprehensive pre- and post-implant support, ensuring patients and families are guided through every step of the journey.
