About Dr. Biji Bahuleyan

The surgeon whose techniques are taught across the world

Dr. Biji Bahuleyan is one of India's most internationally accomplished neurosurgeons. After completing his MCh in Neurosurgery from the prestigious Christian Medical College (CMC) Vellore, he pursued three separate fellowships in the United States — at Harvard Medical School, the Cleveland Clinic, and Case Western Reserve University — each focusing on a different subspecialty of neurosurgery.

Over a career spanning more than 25 years, Dr. Bahuleyan has pioneered four world-first surgical techniques, published over 40 peer-reviewed papers, and earned more than 600 citations in the global medical literature. His innovations have been featured on three international journal covers and referenced in the CNS 2020 Guidelines and UpToDate — the world's most widely used clinical decision resource.

Today, as Senior Consultant at Caritas Neuro Sciences, Kottayam, he brings that rare combination of global training and local accessibility to patients across Kerala and beyond.

Frequently Asked Questions

Common questions about neurosurgical care

When should I see a neurosurgeon?

You should consider seeing a neurosurgeon if you experience persistent or worsening headaches, especially with vision changes; numbness, tingling or weakness in your limbs; chronic neck or back pain that hasn't responded to conservative treatment; seizures or unexplained episodes of loss of consciousness; difficulty with balance or coordination; or if your doctor has identified an abnormality on a brain or spine scan. A neurosurgical consultation doesn't always mean surgery — it means getting an expert opinion on the best path forward.

Why should I choose Dr. Biji Bahuleyan over other neurosurgeons?

Dr. Bahuleyan brings a unique combination of international training and local accessibility. With three separate US fellowships at Harvard Medical School, the Cleveland Clinic, and Case Western Reserve University, he has trained at the very institutions that define global standards in neurosurgery. He has pioneered four world-first surgical techniques, published over 40 papers cited more than 600 times, and his work is referenced in the CNS 2020 Guidelines and UpToDate. This level of research contribution and surgical innovation is exceptionally rare, and he makes it available right here in Kerala at Caritas Hospital, Kottayam.

Can I get a second opinion from Dr. Bahuleyan?

Absolutely. Second opinions are a normal and encouraged part of responsible medical care — especially for neurosurgical conditions where the stakes are high. You can visit in person at Caritas Hospital, Kottayam, or reach out via WhatsApp or email with your reports and scans. Dr. Bahuleyan will review your case thoroughly and provide an honest assessment of your options, including whether surgery is truly necessary.
