The simplest of the Neurosign range With 2 channels, powerful audio, an easy to understand display, and a built-in stimulator, the Neurosign 100 intra-operative nerve monitor is an excellent choice when a simple monitor is required for facial and laryngeal nerve monitoring. Neurosign 100 enables ENT surgeons to monitor the facial nerve during mastoidectomy and is used by general surgeons to monitor the recurrent and superior laryngeal nerves during procedures involving the thyroid gland. Neurosign 100 is also suitable to monitor the accessory, hypoglossal or trigeminal nerves individually.
