the art of neuromonitoring

in neuro and skull base surgery

Situation

Multimodal neuromonitoring in neuro and skull base surgery

Nearly all neurosurgical interventions in the head and neck area pose a risk to neural structures. Motor nerves, sensory nerves as well as cerebral structures such as certain areas in the brain may be injured in neurosurgical intervention. In order to identify and monitor the structures most at risk and their function, intraoperative neuromonitoring is often applied.

 
 
 

Multimodal neuromonitoring

• EMG • AEP

Our AVALANCHE® SI neuromonitor has up to 8 channels and can measure various combinations of modalities so that the real-time status of various neural pathways can be assessed during surgery.

EMG

Motor cranial neural pathways can be monitored using EMG techniques. Stimulation is achieved through hand-held stimulation probes right at the operation site. The arising motor unit action potentials (MUAP) are picked up at the innervated target muscles and processed by the neuromonitor.

AEP

When operating on the ear and near the auditory nerve, measuring auditory evoked potentials (AEP) helps the surgeon to identify impaired function. Pre-defined clicking sounds are played to the patient via earphones. The action potentials thus triggered are picked up from the skull via needle electrodes. The AEP measurements provide an insight into the functionality of the auditory nerve (N. vestibulocochlearis) and the brain stem.

NEEDLE ELECTRODES

Colour-coded needle electrodes for recording and stimulation

Whether one or several channels are required for the recording of EMG or EP signals or nerves and muscular tissue are to be stimulated, needle electrodes by Dr. Langer Medical GmbH will give you ample choice for neuromonitoring.

Various lengths, shapes and geometric arrangements as well as a palette of colours to suit your particular application purposes are available - the choice is yours.
