Dr. Biji Bahuleyan brings Cleveland Clinic–level precision and Harvard-trained expertise to advanced brain, spine, and epilepsy surgery at Caritas Hospital, Kottayam.
Dr. Biji Bahuleyan is one of India’s most internationally trained neurosurgeons, bringing 25 years of expertise in brain, spine, and epilepsy surgery to patients at Caritas Neuro Sciences, Caritas Hospital, Kottayam.
After completing his MCh from CMC Vellore, Dr. Bahuleyan pursued three distinct fellowships at leading US academic medical centers — minimally invasive neurosurgery at Case Western Reserve, spine surgery at Harvard Medical School’s Brigham & Women’s Hospital, neuro-oncology and functional neurosurgery at the Cleveland Clinic. He is ECFMG-certified with all three USMLE steps cleared.
Dr. Bahuleyan has pioneered four endoscopic epilepsy surgery techniques never before described in world medical literature — innovations now referenced in international guidelines, UpToDate, Nature Reviews Disease Primers, and six Springer reference volumes. His 40+ publications have been cited over 600 times worldwide.
Combining fellowship-level subspecialty training with advanced surgical technology — each area reflects dedicated training at the world’s leading institutions.
Comprehensive surgical treatment for all types of brain tumors — from meningiomas and gliomas to complex skull base tumors, pituitary adenomas, and acoustic neuromas. Advanced techniques including awake craniotomy, endoscopic approaches, and image-guided neuronavigation.
Fellowship-trained spine surgery addressing degenerative, traumatic, and complex spinal conditions. Minimally invasive approaches including tubular decompression, percutaneous instrumentation, and endoscopic discectomy, alongside complex reconstruction.
Pioneer with four endoscopic techniques never previously described in world medical literature and 200+ epilepsy surgeries. Training at the Cleveland Clinic — home to the world’s largest epilepsy surgery program.
With 300+ endoscopic procedures and dedicated fellowship training, Dr. Bahuleyan is among the most experienced endoscopic neurosurgeons in Kerala. Small openings, less pain, shorter hospital stays.
Advanced surgical management of complex cranial conditions — skull fractures, craniofacial reconstruction, Chiari malformations, aneurysms, arteriovenous malformations, and deep brain stimulation for movement disorders.
Between 2010 and 2013, Dr. Bahuleyan developed and published four minimally invasive endoscopic epilepsy surgery techniques never before described in global medical literature.
Disconnection of an entire brain hemisphere through an endoscopic approach. Selected as the cover illustration of the journal.
Precise placement of depth electrodes for epilepsy monitoring using endoscopic guidance, improving accuracy while minimizing risk.
Complete disconnection of the corpus callosum through an endoscopic approach — a less invasive option for patients with generalized epilepsy.
Selective removal of epilepsy-causing tissue through an endoscopic corridor. Received a three-page invited commentary by Professor Michael Gaab.
These techniques are codified into clinical practice — referenced in CNS 2020 Guidelines, UpToDate, Nature Reviews Disease Primers, and six Springer reference volumes. His research earned three cover illustrations in the Journal of Neurosurgery: Pediatrics.
Every procedure reflects training at institutions that define the global standard. Harvard spine fellowship, Cleveland Clinic oncology and functional neurosurgery fellowships, and Case Western minimally invasive training. ECFMG-certified.
With 40+ publications and roles as Associate Editor of Surgical Neurology International, every clinical decision is grounded in the best available evidence. He does not recommend surgery when conservative management offers a reasonable path.
Patients describe Dr. Bahuleyan as a surgeon who explains every detail in language they understand. He remains personally accessible via WhatsApp for follow-up.
MRI and CT available 24/7, state-of-the-art operating microscopes, neuronavigation systems, intraoperative neurophysiological monitoring, and a dedicated Neurosurgical ICU.
Meticulous pre-operative planning, preference for minimally invasive approaches, precise intraoperative monitoring, and structured post-operative protocols.
Dr. Bahuleyan explains complex neurosurgical conditions in clear, accessible language.
Dr. Biji Bahuleyan serves as Senior Consultant – Neurosurgery at Caritas Neuro Sciences, Caritas Hospital, Thellakom, Kottayam — one of Central Kerala’s most respected healthcare institutions.
Founded over 60 years ago, Caritas Hospital has grown into a 635-bed multispecialty tertiary care center delivering advanced medical and surgical services to patients from Kottayam, Pathanamthitta, Idukki, Alappuzha, and beyond.
Patients benefit from advanced imaging available 24/7 including high-field MRI and multi-slice CT, modern neurosurgical operating theaters, a dedicated Neurosurgical ICU, and a 24-hour stroke response system.
Dr. Bahuleyan has authored over 40 publications in the Journal of Neurosurgery: Pediatrics, World Neurosurgery, Neurology India, British Journal of Neurosurgery, Child’s Nervous System, and Pediatric Neurosurgery. First author in Benzel’s Spine Surgery — the world’s most referenced spine surgery textbook.
His techniques are referenced in the CNS 2020 Guidelines, UpToDate, Nature Reviews Disease Primers, and six Springer reference volumes.
He serves as Associate Editor of Surgical Neurology International, teaching faculty at AANS and WFNS workshops, and has earned four best-paper and best-poster awards.
Many patients delay seeking a consultation because “neurosurgery” sounds daunting. In reality, it is simply the first step toward understanding your condition.
Persistent or worsening headaches with nausea, vomiting, or visual changes. Seizures occurring for the first time or increasing despite medication. Weakness, numbness, or tingling in the limbs. Back or neck pain radiating into the limbs, especially with weakness or bladder changes. A diagnosis of a brain or spine tumor on imaging.
Seeking a neurosurgeon does not mean surgery is certain. Many conditions can be managed with medication, monitoring, physical therapy, or other non-surgical approaches.
Modern neurosurgeons operate with surgical microscopes, neuronavigation providing real-time 3D guidance, intraoperative neurophysiological monitoring, and endoscopic instruments allowing complex procedures through openings as small as a centimeter.
If you have received a diagnosis and are unsure about the recommended treatment plan, seeking a second opinion is encouraged. Dr. Bahuleyan welcomes patients seeking a second opinion. Bring your MRI/CT reports, previous medical records, and any questions.
Whether you are facing a new diagnosis, exploring surgical options, or seeking a second opinion — Dr. Biji Bahuleyan and the Caritas Neuro Sciences team are here to help.
Schedule an in-person evaluation at Caritas Hospital, Kottayam. Bring your imaging scans, prior records, and current medications.
