Senior Consultant Neurosurgeon

The Brain.

It's not just my profession. It's my life's calling. For over 17 years, I've dedicated myself to understanding and healing the human brain and spine — one of the most complex systems in the known universe.

Every case I encounter is unique, every person I treat is a story worth listening to, and every surgery is a responsibility I hold with the utmost care. From performing Deep Brain Stimulation for Parkinson's to treating aneurysms and spine disorders using minimally invasive methods, I strive to bring together cutting-edge science and deep compassion to give my patients not just a solution — but a future.

My Approach.

Compassion

Every patient is unique. I listen, understand, and tailor my approach to their individual needs.

Innovation

I leverage the latest advancements in neurosurgery to provide the best possible outcomes.

Excellence

My commitment to excellence drives me to continuously improve and refine my skills.

Education

I believe in empowering my patients with knowledge about their conditions and treatment options.

What I Do.

Here are the areas I specialize in.

Aneurysm Care

Treatment to prevent or repair brain vessel rupture.

Deep Brain Stimulation (DBS)

Electrical therapy for neurological disorders.

Pituitary Tumor Surgery

Removal of tumors near the brain base.

Brain & Spine Trauma

Emergency care for brain and spine injuries.

Endoscopic Spine Surgery

Minimally invasive spine treatment.

Keyhole Spine Surgery

Small-incision surgery for spinal issues.

Brain Tumor Removal

Precise surgical removal of brain tumors.

Awake Craniotomy

Safe brain surgery while the patient is awake.

My Expertise.

  • I perform hybrid neurosurgical procedures, combining endovascular techniques with microsurgery for the safe and effective treatment of brain tumors, aneurysms, and arteriovenous malformations (AVMs). This approach minimizes the risks of open surgery while maximizing outcomes.
  • I specialize in Deep Brain Stimulation (DBS) for Parkinson's disease and other movement disorders, helping patients regain independence and control over their lives.
  • I conduct awake craniotomies with intraoperative neuromonitoring to safely remove tumors located near speech, motor, or cognitive areas, prioritizing function preservation throughout the procedure.
  • My expertise includes endonasal endoscopic skull base surgery to treat pituitary tumors, craniopharyngiomas, and other midline lesions through the nasal passages—offering a scar-free, minimally invasive alternative.
  • I offer , including coiling for aneurysms and embolization for AVMs, as well as carotid artery stenting for stroke prevention in patients with significant carotid artery narrowing.
  • I also treat cranial nerve disorders such as trigeminal neuralgia and hemifacial spasm using both medical management and microsurgical techniques to provide long-lasting relief.
  • For deep-seated brain conditions, I perform stereotactic procedures using advanced navigation systems for pinpoint accuracy in lesion targeting and therapeutic delivery.
  • I carry out endoscopic and keyhole spine surgeries through small incisions, which minimize tissue damage and support faster recovery with less postoperative discomfort.
  • I perform spinal stabilization and fusion procedures, including TLIF, vertebroplasty, kyphoplasty, and odontoid fixation, to restore spinal alignment and function in cases of degeneration, trauma, or deformity.
  • I manage spinal cord tumors with minimally invasive techniques, ensuring safe tumor removal while preserving healthy structures and reducing recovery time.
  • In cases of traumatic injury, I stabilize spinal fractures using keyhole pedicle screw fixation to enable early mobilization and faster rehabilitation.
  • I provide timely, expert neurosurgical intervention for brain and spine trauma, addressing life-threatening injuries in emergency settings with precision and urgency.
  • I perform craniofacial reconstructive surgeries to repair facial fractures and correct congenital deformities, combining functional restoration with aesthetic outcomes.
  • In my pediatric neurosurgical practice, I treat children with congenital conditions such as spina bifida and Chiari malformations, working closely with families to deliver compassionate, age-appropriate care and long-term support.

My father underwent a complex brain surgery performed by Dr. Arjun Chacko at Rajagiri Hospital, Kochi, and we are profoundly grateful for the exceptional care he received. Dr. Chacko's expertise and skill were evident throughout the entire process, from the initial consultation to the post-operative care. He explained everything clearly and patiently, which greatly eased our anxieties. The surgery was successful, and my father's recovery has been remarkable. Beyond Dr. Chacko's expertise, the nursing services and care at Rajagiri Hospital were outstanding. The nurses were incredibly attentive, compassionate, and professional. They provided round-the-clock care, ensuring my father was comfortable and well supported. Their dedication and kindness made a significant difference in his recovery. The entire neurosurgery team, including the support staff, were excellent. We are incredibly thankful to Dr. Chacko and the entire Rajagiri Hospital team for their dedication and professionalism.

My uncle was admitted under Dr. Arjun Chacko, Neurosurgery and underwent spine surgery. I would like to share our experience. When we brought the patient to the hospital in a wheelchair for surgery, he had 0% mobility and confidence in walking. He was unable to hold water or food by himself and needed assistance for everything. However, after the surgery, he has shown remarkable improvement. He can now hold things on his own and feed himself. Additionally, he is walking with the assistance of one person, and his confidence has significantly increased, some physiotherapy is required for the better results. The doctor explained the procedure very clearly and was exceptionally skilled and reassuring. The nursing team worked tirelessly with dedication, showing no signs of laziness. Their care, compassion, and professionalism were truly commendable. Housekeeping was also excellent, ensuring a clean and comfortable environment. Overall, the surgery has made a tremendous difference in the patient's life, and we are deeply grateful for the exceptional medical care provided.
