The brain, spinal cord and surrounding nerves contain several closely positioned structures that control movement, speech, vision, sensation and other essential functions. Neurosurgical procedures therefore require careful planning, precise visualisation and accurate localisation of the area being treated. Apollo Adlux Hospital, Kochi, is equipped with the Medtronic StealthStation S8 Neuronavigation System, which supports image-guided brain and spine procedures. Neuronavigation can be compared to a GPS system used during surgery. It helps the neurosurgeon understand the position of surgical instruments in relation to the patient’s anatomy using previously acquired imaging data.

What Is a Neuronavigation System?

A neuronavigation system combines imaging, computer software and instrument-tracking technology to help surgeons locate anatomical structures during surgery.

The Medtronic StealthStation S8 is designed to precisely locate anatomical structures during open or percutaneous neurosurgical and spinal procedures. It can integrate imaging datasets and track surgical instruments to assist the surgeon during an operation.

Before surgery, CT or MRI images may be uploaded to the system. These images can be used to:

•            Study the location and extent of a lesion
•            Plan the safest surgical approach
•            Identify nearby blood vessels and critical structures
•            Guide surgical instruments during the procedure
•            Confirm the area being treated

Neuronavigation supports the surgeon’s clinical judgement rather than replacing surgical skill or decision-making.

How Does Neuronavigation Work?

The process generally involves the following stages:

Preoperative Imaging

The patient undergoes an MRI or CT scan. The images provide detailed information about the brain, spine, tumour, blood vessels or other anatomical structures.

Surgical Planning

The neurosurgeon studies and processes the images using navigation software. The safest route towards the surgical target can then be planned.

Patient Registration

At the beginning of surgery, the patient’s actual anatomy is matched with the digital images displayed on the navigation system.

Instrument Tracking

Specially recognised surgical instruments are tracked by the system. Their location is displayed in relation to the patient’s imaging data, helping the surgeon maintain orientation throughout the procedure.

Conditions in Which Neuronavigation May Be Used

Neuronavigation may support selected procedures involving:

•            Brain tumours
•            Deep-seated brain lesions
•            Brain biopsies
•            Skull-base tumours
•            Hydrocephalus
•            Epilepsy surgery
•            Intracranial cysts
•            Vascular abnormalities
•            Complex spinal disorders
•            Spinal tumours
•            Minimally invasive spine surgery
•            Placement of spinal implants or screws

The suitability of navigation depends on the diagnosis, location of the condition and the surgical approach selected.

Role of Neuronavigation in Brain Tumour Surgery

Brain tumours may develop close to areas responsible for speech, movement, vision or memory. Neuronavigation helps the surgical team correlate the operative field with MRI or CT images.

This may help the neurosurgeon:

•            Locate the tumour accurately
•            Plan an appropriate incision
•            Identify the tumour’s boundaries
•            Avoid unnecessary disturbance of healthy tissue
•            Select a direct and carefully planned surgical pathway

In some cases, neuronavigation may be combined with an advanced surgical microscope, fluorescence imaging, neurophysiological monitoring or endoscopic techniques.

Role in Spine Surgery

In complex spine procedures, neuronavigation can help surgeons understand the three-dimensional anatomy of the vertebrae and surrounding structures.

It may support:

•            Accurate placement of spinal screws
•            Treatment of spinal deformities
•            Minimally invasive spine surgery
•            Spinal tumour procedures
•            Revision spine surgery
•            Surgery involving complex or abnormal anatomy

The technology is particularly useful where anatomical landmarks are difficult to visualise directly.

Potential Benefits of Neuronavigation

Depending on the procedure and patient’s condition, neuronavigation may support:

•            Precise localisation of the surgical target
•            Improved surgical orientation
•            Detailed preoperative planning
•            Smaller and more targeted surgical approaches
•            Reduced disturbance of surrounding tissue
•            Guidance during complex brain and spine procedures
•            Integration of multiple imaging datasets
•            Better coordination between imaging and surgery

These potential advantages vary according to the diagnosis, complexity of the procedure and surgeon’s assessment.

Is Neuronavigation Safe?

Neuronavigation itself is a guidance technology. The risks associated with treatment are mainly related to the underlying disease and the surgical procedure being performed.

The accuracy of navigation depends on several factors, including:

•            Quality of imaging
•            Correct patient registration
•            Appropriate equipment calibration
•            Positioning of the patient
•            Intraoperative anatomical changes
•            Training and experience of the surgical team

The surgical team continuously correlates navigation information with actual anatomical findings.
