Which of the following is a risk associated with foramen ovale electrodes?

Foramen ovale electrodes are used in neurophysiological monitoring, particularly for procedures involving the heart and brain. One of the potential risks associated with the placement of these electrodes is facial numbness. This complication can occur if the electrode placement inadvertently affects nearby neural structures, particularly as the electrodes might impinge on or irritate cranial nerves that control sensation in the face.

Understanding this particular risk is crucial for healthcare professionals when considering the use of foramen ovale electrodes for monitoring. While other adverse effects such as hearing loss, motor paralysis, and respiratory failure can occur in various medical contexts, they are not specifically associated with the use of foramen ovale electrodes. Therefore, facial numbness is the more pertinent risk to consider during the monitoring process with these electrodes.
