What is it about?

Intraoperative neuromonitoring of the TA muscles alone may miss a partial RLN injury in some cases.

Why is it important?

This study suggests preferential damage to PCA-nerve fibers in RLN lesions, particularly in iatrogenic lesions. Traction on the nerve is to be understood as the predominant mechanism of injury.


Intraoperative neuromonitoring should include the evoked PCA-EMG in future.
