Internationally trained pediatric neurosurgical expertise at Caritas Neuro Sciences, Kottayam. Developer of four first-in-literature minimally invasive endoscopic techniques adopted worldwide.
Children facing neurological conditions deserve the highest standard of surgical expertise. Dr. Biji Bahuleyan brings internationally validated pediatric neurosurgical training to Kerala, offering families access to the same calibre of care found at leading centres in the United States and Europe.
With fellowship training at Rainbow Babies and Children’s Hospital, Case Western Reserve University (CWRU), Cleveland, Ohio, Dr. Bahuleyan completed one of the most rigorous pediatric neuroendoscopy programmes in the world. During this fellowship, he developed four first-in-literature minimally invasive endoscopic techniques for treating intractable epilepsy in children — procedures now referenced in international textbooks and adopted by neurosurgical centres worldwide.
His pioneering research was published in the official journal of the American Association of Neurological Surgeons (AANS) and was selected as the cover illustration of the Journal of Neurosurgery: Pediatrics.
As Senior Consultant at Caritas Neuro Sciences, Caritas Hospital, Kottayam, Dr. Bahuleyan has performed over 200 epilepsy surgeries and more than 300 endoscopic third ventriculostomies (ETVs) for hydrocephalus, achieving a 75% shunt-free rate — outcomes that match the best international benchmarks.
A 24-year-old patient who suffered cardiac arrest and was clinically dead for nearly 20 minutes during a complex endoscopic brain procedure was saved by Dr. Bahuleyan’s surgical expertise. The case, involving meningitis caused by the exceptionally rare organism Stenotrophomonas maltophilia (fewer than 20 reported cases globally), was covered by the Times of India.

Dr. Bahuleyan’s neurosurgical oncology fellowship at the Cleveland Clinic’s Burkhardt Brain Tumor Center — training under Dr. Gene Barnett — equips him with expertise in intraoperative MRI-guided resection, awake brain surgery, and DTI-based resections.
His research on pediatric meningiomas has been cited by 114 peer-reviewed articles worldwide, referenced in UpToDate® and multiple Springer textbooks.
Published in Acta NeurochirurgicaFewer than 5% of neurosurgeons worldwide are trained in epilepsy surgery. In India, this complex evaluation is available at fewer than 15 centres. Dr. Bahuleyan trained at SCTIMST Trivandrum (top epilepsy centre in South-East Asia) and Case Western Reserve University.
He developed four first-in-literature keyhole endoscopic epilepsy techniques — transforming open-skull procedures into minimally invasive approaches. Over 200 epilepsy surgeries performed.
300+ ETVs performed with a 75% long-term shunt-free success rate — validated by a landmark 100-patient study with 5.1-year mean follow-up. This study identified that preoperative MRI showing inferior bowing of the third ventricle floor predicts success.
Now codified in the CNS 2020 Pediatric Hydrocephalus Guidelines as one of only 6 pivotal studies. Also cited in Nature Reviews Disease Primers and five textbooks.

First minimally invasive approach to a radical procedure for treating seizures originating from one hemisphere of the brain. Selected as the cover illustration of the Journal of Neurosurgery: Pediatrics and won the Best Paper Award at CWRU.
Novel technique for precise placement of recording electrodes in the hippocampus under direct endoscopic vision, reducing risk of injury to vital structures including the midbrain, pons, and medulla. Now serves as the benchmark for modern SEEG posterior trajectories.
The most common epilepsy procedure, applicable to ~70% of surgical epilepsy patients, performed through a keyhole approach. Professor Michael Gaab, the “father of endoscopic neurosurgery,” wrote a three-page invited commentary praising this technique.
First keyhole approach for disconnecting the two brain hemispheres to treat severe drop-attack seizures. Now referenced in six Springer/Hermes volumes including “Advances and Technical Standards in Neurosurgery” (2024) and “The Corpus Callosum” (2023).

Paediatric neurosurgical procedures at Caritas Neuro Sciences are supported by state-of-the-art technology and multidisciplinary collaboration.
Expert answers to the questions families most frequently ask about pediatric neurosurgery.
Paediatric neurosurgery can be performed at any age, including in neonates. Dr. Bahuleyan’s training at Rainbow Babies and Children’s Hospital, one of the top paediatric centres in the United States, included managing neurological conditions across all age groups from newborns to adolescents.
Yes. Endoscopic and minimally invasive approaches often result in less surgical trauma, reduced blood loss, shorter hospital stays, and faster recovery. Dr. Bahuleyan’s four first-in-literature endoscopic techniques were specifically designed to bring these advantages to paediatric patients with complex conditions.
Dr. Bahuleyan’s published research demonstrates a 75% long-term shunt-free success rate with ETV, validated across 100 consecutive patients with over 5 years of follow-up. This is among the highest reported rates in the literature and has been incorporated into the CNS 2020 Pediatric Hydrocephalus Guidelines.
Yes. He is one of approximately 20 epilepsy surgeons in India, with specialized training from SCTIMST Trivandrum and Case Western Reserve University. He offers comprehensive epilepsy surgery evaluation and operates both at Caritas Hospital and as a visiting epilepsy surgeon at other centres across India.
