C2 Xplore - Significant risk reduction of latrogenic injuries during facial nerve surgery

Facial nerve surgery operations:

  • are very complex due to their fine structure and fan-shaped nerves
  • require high precision and
  • are thus a particular challenge for surgeons.

Therefore, intraoperative neuromonitoring (IONM) has been established for many years, especially in the field of facial nerve surgery. >> This can support the surgeon in localizing the nerve branches and increase patient safety.


Protection of the facial nerves - minimization of risks

Neuromonitoring in facial nerve surgery can be performed in two different ways:

  • Acoustic and visual display of signals and spontaneous activities resulting from the irritation of the nerve branches, for example, by mechanical manipulation of the nerves.
  • For the detection and display of individual nerve branches in the parotid gland, the hand-held probes are used. This stimulation is electrical and the resulting muscle contractions are reported both visually and acoustically.

Where tympanoplasty is performed or a cochlear implant inserted, inomed's neuromonitoring is a useful tool that helps prevent nerve injury during drilling near the bony facial canal. Neuromonitoring techniques are used during mastoidectomy for a risk reduction of nerve injury.


Measuring mode in facial nerve surgery

Hand-held stimulation probes are used to localize the nerve branches in facial nerve surgery. The acoustic identification of the nerve by the so-called Channel Ident function is performed by the different sound output of each channel and thus each nerve.

The highly selective bipolar probes can be used to monitor nerve branches and their function in close proximity. Monopolar probes, on the other hand, have a wider range of action. To record the electrophysiological signals, electrodes must be placed in the respective indicator muscle. When significant changes in the amplitude or latency of the muscle responses occur, acoustic and visual information is output. This is also the case when spontaneous activity occurs. Detected spontaneous activity is automatically recorded and can be annotated for documentation.
