FOR SURGEONS
Real-time functional guidance at the table.
- Modalities planned with you around the neural structures at risk
- Instant, interpreted feedback — not raw traces
- Added confidence to take on complex cases
Intraoperative Neuromonitoring (IONM) uses electrophysiological signals — EEG, EMG and evoked potentials — to check the functional integrity of nerves, the spinal cord and parts of the brain while surgery is under way.
It is now a standard of care in neuro, spine and vascular procedures: during deformity correction, tumour excision and any surgery close to neural elements. Changes are caught as they happen, not discovered after the patient wakes up.
Single or multi-modality monitoring, planned with the surgeon around the procedure and the neural structures involved.
Continuous muscle activity that flags irritation of the corresponding nerve.
Stimulation in the field to find nearby nerves and test their integrity.
Threshold EMG at the screw head confirms correct placement in spine surgery.
Identification and localisation of neural structures in the operative field.
Protects facial and cranial nerves in skull-base, ENT and parotid surgery.
Checks the posterior sensory pathway from peripheral nerve to sensory cortex.
Checks the anterior motor pathway from motor cortex to the relevant muscles.
Direct corticospinal tract recording, valuable in spinal cord tumour resection.
Evaluates neuronal activity along the auditory pathway and brainstem.
Confirms the visual pathway is intact during pituitary and posterior circulation work.
Cortical activity from scalp or directly from the brain surface.
Maps eloquent cortex so tumour and epilepsy resections can go further, safely.
Our technologist arrives early, meets the team, reviews the history and agrees which signals to monitor.
The monitoring program is configured and sensors are placed once the patient is under anaesthesia.
Signals are watched continuously; any deviation is interpreted and reported to the surgeon instantly.
Sensors are removed and a full report of the monitored signals and events is shared with the team.
The set of modalities depends on which neural structures are at risk. A detailed procedure-by-modality matrix is available for surgical teams on request.
Your surgery involves or is close to the brain, spinal cord or nerves. IONM lets your surgical team see how those structures are functioning throughout the operation and respond immediately if something changes.
No special preparation is needed. Your team decides the monitoring plan based on your history and pre-operative neurological function.
Small needle sensors are placed only after you are asleep under anaesthesia, and all of them are removed when surgery is complete.
IONM is provided at the request of your surgeon as an additional safety measure. Please speak to your doctor about whether it is right for your procedure.
Available around the clock, 365 days a year, for scheduled cases and enquiries.
