India’s Largest IONM Study: Transforming Neurosurgical Safety at Dr. Rao’s IIN (Dr. Rao’s Hospital)
Introduction: A Landmark Moment in Indian Neurosurgery
At the prestigious SIONCON 2025 hosted by NIMHANS, a groundbreaking milestone in neurosurgery was presented—India’s largest intraoperative neuromonitoring (IONM) study involving 1008 cases.
Led by Dr. Mohana Rao Patibandla, this study from Dr. Rao’s International Institute of Neurosciences (Dr. Rao’s Hospital) represents a paradigm shift in how neurosurgeries are performed, monitored, and optimized for patient safety.
This is not just a clinical milestone—it is a national benchmark redefining surgical precision, risk reduction, and outcome predictability in brain and spine surgery.
What is Intraoperative Neuromonitoring (IONM)?
Intraoperative neuromonitoring (IONM) is a sophisticated technique used during neurosurgery to continuously monitor the functional integrity of the nervous system.
It tracks:
- Brain signals
- Spinal cord activity
- Peripheral nerve responses
This real-time feedback allows surgeons to detect potential neurological injury instantly and take corrective action before permanent damage occurs.

The 1008-Case Study: Scale, Scope, and Significance
The study presented at SIONCON 2025 is remarkable for several reasons:
🔬 Study Highlights
- 1008 neurosurgical procedures
- Conducted over 5 years
- Included:
- Brain tumor surgeries
- Spine surgeries
- Epilepsy surgeries
- Pediatric neurosurgery
- Awake craniotomies
This makes it one of the largest real-world neurosurgical datasets in India focusing on IONM.
Key Clinical Outcomes: Data That Matters
The results from the study underscore the transformative impact of IONM:
- Sensitivity: 85.7%
- Specificity: 98.8%
- Prevention of neurological deficits: 78.5%
- Recovery rate in transient deficits: 94%
- Functional independence (KPS ≥80): 91.6%
👉 Reference clinical standards from World Health Organization
These outcomes demonstrate that real-time monitoring directly translates into better patient outcomes.
Why This Study Changes Neurosurgery in India
1. From Reactive to Preventive Surgery
Traditionally, neurosurgery relied heavily on anatomical knowledge and surgical expertise. With IONM:
- Surgeons can predict complications before they occur
- Real-time alerts enable immediate corrective actions
This marks a transition toward preventive neurosurgery.
2. Standardizing Safety Protocols
The study advocates for making IONM a standard of care, especially in:
- Brain tumor surgeries
- Spine deformity corrections
- Skull base procedures
- Pediatric neurosurgery
👉 Guidelines supported by World Federation of Neurosurgical Societies
3. Improving High-Risk Surgery Outcomes
IONM showed significant benefits in:
- Skull base tumors
- Spinal cord surgeries
- Motor and speech areas of the brain
- Epilepsy surgeries
- Awake craniotomy

The Innovation: “Staged Closure” Strategy
One of the most impactful contributions of the study is the “staged closure” approach:
How it works:
- IONM detects signal deterioration
- Surgery is paused
- Neural function is allowed to recover
- Surgery resumes safely
This strategy prevented permanent neurological damage in multiple cases.
Awake Brain Surgery: A New Frontier
One of the standout findings was the near-zero long-term deficits in awake craniotomy cases.
This technique allows:
- Real-time speech and motor testing
- Maximum tumor removal with minimal risk
- Personalized surgical precision

Children undergoing neurosurgery benefit significantly from IONM:
- Prevents lifelong disability
- Ensures safer tumor and spine surgeries
- Enables functional preservation
