Neurosurgery in 2025: Smaller Incisions, Smarter Guidance, Better Outcomes
A decade ago, a patient in Thane requiring complex brain or spine surgery had one of two options: travel to a major centre in South Mumbai and hope for a surgical team with access to modern technology, or accept care with whatever equipment the local hospital had available.
That disparity has closed. The technological capabilities that define modern neurosurgery operating microscopes, neuronavigation, intraoperative neurophysiological monitoring, endoscopic skull base and spine surgery, high-resolution intraoperative imaging are available at Stellars Hospital, Thane.
What does this mean for patients? It means that the surgery Dr. Bharat Shinde performs in Thane is guided by the same standards of technology and safety as any leading neurosurgical centre. The result: less risk to critical structures, more complete tumour and lesion removal, and faster, more predictable recovery.
This blog explains the key technologies, what they do, and why they matter for your outcome.

Technology 1: Neuronavigation GPS for the Brain
Neuronavigation is the neurosurgical equivalent of GPS a real-time, three-dimensional guidance system that uses pre-operative MRI or CT data to show the surgeon exactly where instruments are positioned relative to the patient’s brain or spine anatomy at every moment of the surgery.
Before surgery, the patient’s imaging is loaded into the neuronavigation system. Reference markers are registered to the patient’s anatomy on the operating table. From that point on, every movement of the surgical instrument is displayed in real time on a screen showing its position within the three-dimensional MRI reconstruction.
What this means for patients:
- Craniotomies are planned with surgical millimetre precision exactly over the tumour, not approximated
- Deep lesions (deep-seated tumours, cavernomas) can be accessed through the smallest possible corridor, minimising disruption to surrounding normal brain
- Screw placement in spine surgery is guided to within 1–2 mm of the planned position, eliminating pedicle screw malposition
- The surgeon knows at every moment whether they are approaching a critical structure the motor cortex, the visual cortex, a major vessel before reaching it
| Why Neuronavigation Matters for Brain Tumour Surgery
The margin between a complete tumour resection and an incomplete one and between a successful surgery and a neurological deficit is often measured in millimetres in brain surgery. Neuronavigation allows the surgeon to stay precisely within the planned surgical corridor, excise the entire tumour while identifying and protecting surrounding structures, and confirm intraoperatively that the planned resection has been achieved. It is not a convenience; it is a safety standard. |
Technology 2: Intraoperative Neurophysiological Monitoring (IONM)
Intraoperative neurophysiological monitoring (IONM) is a system of continuous real-time electrical monitoring of the nervous system during surgery. Electrodes placed on the patient record the electrical activity of the motor pathways, sensory pathways, and cranial nerves throughout the procedure.
There are several modalities:
- [object Object] electrical signals sent from the brain’s motor cortex are recorded in the limb muscles. A drop in MEP amplitude warns the surgeon that the motor pathway is at risk, allowing immediate corrective action.
- [object Object] sensory signals from the limbs are recorded in the brain. Changes indicate sensory pathway compromise.
- [object Object] continuous recording from nerve root territory muscles during spine surgery alerts the surgeon to nerve root irritation or injury in real time.
- [object Object] used in acoustic neuroma and posterior fossa surgery to protect hearing and facial nerve function.
The purpose: to detect neurological compromise during surgery before it becomes permanent, giving the surgical team time to respond by changing position, removing a retractor, adjusting an implant, or pausing the dissection.
Intraoperative neurophysiological monitoring does not prevent all neurological complications it provides an early warning system. The value is in the time it creates for the surgeon to act. In spinal cord and brain surgery, the difference between a warning at the right moment and discovering a deficit post-operatively is often the difference between full recovery and permanent deficit.
Technology 3: Operating Microscope The Foundation of Safe Neurosurgery
The operating microscope has been the cornerstone of neurosurgery for over 50 years, but modern iterations bear little resemblance to early models. Today’s neurosurgical microscopes provide:
- High-magnification (up to 40x) with variable zoom during surgery
- Integrated fluorescence modes 5-ALA fluorescence for high-grade glioma, indocyanine green (ICG) for vascular anatomy visualisation
- Built-in illumination that penetrates deep surgical corridors without shadows
- Motorised positioning allowing hands-free repositioning during surgery
- Integration with neuronavigation for continuous positional reference
For the patient, the operating microscope means: disc fragments that would be missed by the naked eye are found and removed, tumours are excised to their true margin rather than an approximated edge, and critical structures nerves, vessels, spinal cord are visualised with the clarity needed to protect them.
Technology 4: Endoscopic Neurosurgery Inside the Brain Without Opening the Skull
Endoscopic neurosurgery uses a rigid or flexible camera-telescope (endoscope) to access structures within the brain and skull base through natural orifices or very small openings without requiring a craniotomy in many cases.
✔︎ Endoscopic Pituitary Surgery
Pituitary tumours are removed entirely through the nostrils using a rigid endoscope and angled instruments. No skin incision. No craniotomy. 270-degree visualisation of the surgical field through angled endoscope lenses eliminates the ‘blind corners’ that limited the older microscopic transsphenoidal approach. Hospital stay: 3–4 days.
✔︎ Endoscopic Third Ventriculostomy (ETV) for Hydrocephalus
A small hole is made in the floor of the third ventricle using a neuroendoscope introduced through a burr hole, creating an alternative CSF drainage pathway for obstructive hydrocephalus without the lifelong implant of a VP shunt in suitable cases.
✔︎ Endoscopic Skull Base Surgery
CSF leaks, skull base tumours, and other skull base pathology can be addressed through the nose or small retromastoid openings with endoscopic visualisation, reducing the size of surgical exposure needed while improving visualisation of complex anatomy.
Technology 5: Intraoperative Imaging Confirmation Before You Close
One of the most significant advances in spine surgery is intraoperative imaging the ability to obtain CT or fluoroscopic images during surgery, on the operating table, before the wound is closed. This allows:
- Immediate confirmation of pedicle screw position malpositioned screws are identified and corrected before the patient wakes up
- Verification of disc height restoration and cage position in fusion surgery
- Confirmation of decompression adequacy in stenosis surgery
- Reduction of revision surgery rates from implant malposition
For the patient: the knowledge that their spine hardware was verified to be correctly positioned before leaving the operating room not discovered to be misplaced on a post-operative CT scan.
What These Technologies Mean for Patients in Thane
The practical implication of all of the above is that patients in Thane and the MMR do not need to travel to Mumbai’s premier hospitals to access technology-guided neurosurgery. At Stellars Hospital, Thane, Dr. Bharat Shinde uses:
- Neuronavigation for brain tumour and complex spine surgery
- Intraoperative neurophysiological monitoring for spinal cord, nerve root, and cranial nerve protection
- High-magnification operating microscope for all brain and spine procedures
- Endoscopic approaches for pituitary surgery, skull base pathology, and hydrocephalus
- Fluoroscopy and intraoperative imaging for spine implant verification
Technology is a tool it amplifies the skills of the surgeon who uses it. The combination of a trained, experienced neurosurgeon and modern neurosurgical technology produces outcomes that neither could achieve alone. At NeuroSpine Thane, both are available.
Frequently Asked Questions
| Q: Does neuronavigation make surgery longer
Neuronavigation adds approximately 15–20 minutes for registration and setup, but typically reduces overall operative time by making dissection more direct and efficient. The safety benefit reduced risk of injury to critical structures vastly outweighs the setup time. |
| Q: Is intraoperative monitoring used for all surgeries at NeuroSpine Thane?
IONM is used for all surgeries where the spinal cord, nerve roots, brainstem, or cranial nerves are at potential risk during the procedure. This includes cervical and thoracic spine surgery, spinal tumour surgery, craniotomy for tumours near eloquent cortex, and posterior fossa surgery. For procedures with minimal neural risk (lumbar microdiscectomy, burr hole drainage), monitoring may not be required. |
| Q: What is awake craniotomy and is it available in Thane?
Awake craniotomy is a procedure in which the patient is conscious during the critical phase of tumour removal, allowing real-time assessment of language and motor function. It is indicated for tumours adjacent to or within eloquent brain areas (language cortex, motor cortex). This technique, combined with direct cortical stimulation, allows the surgeon to maximise tumour removal while confirming in real time that function is preserved. Please discuss availability with Dr. Bharat Shinde. |
| Q: Does technology replace surgical skill?
No. Technology in neurosurgery amplifies surgical skill; it does not replace it. Neuronavigation shows the surgeon where they are it cannot decide what to do. Intraoperative monitoring warns of problems the surgeon must interpret the warning and respond correctly. The foundation of any safe neurosurgical procedure remains the training, experience, and judgment of the surgeon. |
