C2 Xplore – Iatrogenic injury can be significantly reduced in facial nerve surgery

Operations in the field of facial nerve surgery:

  • are very complex because of the delicate structure and the fan-shaped nerves
  • require high accuracy
  • therefore, represent a particular challenge for surgeons.

For this reason, intraoperative neuromonitoring (IONM) has been established for many years, especially in the field of facial nerve surgery >> to support surgeons in locating the nerve branches and thus increasing patient safety.


Saving facial nerves – Minimising risks

Neuromonitoring in facial nerve surgery is used in two ways:

  • Signals and spontaneous activities resulting from irritation of the nerve branches by, for example, mechanical manipulation of the nerves are indicated acoustically and visually.
  • Hand-held probes can be used to locate and indicate individual nerve branches within the parotid. These instruments stimulate the nerves electrically. The resulting muscle contractions are reported 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 milling near the bony facial canal. During mastoidectomy procedures, neuromonitoring techniques are used to reduce the risk of nerve injury.

Measurement mode in facial nerve surgery

A hand-held stimulation probe locates nerve branches during facial nerve surgery. Every channel and thus every nerve makes a different sound allowing acoustic identification of the nerve by the so-called Channel Ident function.

Bipolar probes are highly selective and can be used to monitor nerve branches and their function in the immediate vicinity, whereas monopolar probes have a wider field of action. Electrodes are placed in the corresponding indicator muscle to record electrophysiological signals. If there is any significant change in the amplitude or latency of the muscle responses during surgery, the surgeon is informed visually and acoustically. This also happens if spontaneous activity should occur. Any spontaneous activity detected is automatically recorded and can be annotated for documentation.
