Neurosign’s Sterilized Laryngeal Electrodes minimises damage to the laryngeal or Xth cranial nerves
3 Jan 2008A non-invasive laryngeal electrode helps to lower the risk of damage to the laryngeal or Xth cranial nerves during thyroidectomy or parathyroidectomy and, since it is non-invasive, it also lessens the risk of infection during the monitoring procedure.
Neurosign®’s Sterilized Laryngeal Electrodes were designed with these benefits in mind, and they are now on sale in North America, having been cleared by the FDA in December 2007 (KO71349).
Used to monitor the recurrent laryngeal nerves during thyroidectomy or para-thyroidectomy or the vagus nerve during skull-base procedures, the laryngeal electrode is a sterile, single-use electrode which attaches to a standard endotracheal tube.
The design of the Neurosign Sterilized Laryngeal Electrode allows for rotation of the endotracheal tube during intubation; with competitive devices, considerable care has to be taken with the location of the device, not necessarily easy if the vocal cords cannot be seen due to a large goiter distorting the trachea. Also with these competitive devices, a small rotation of the intubation tube or rotation of the head or neck, such as frequently occurs during surgery, can displace the electrodes embedded in the tube relative to the cords, so decreasing its ability to monitor.
In contrast, however, the Neurosign Sterilized Laryngeal Electrode has a number of "fingers" in the active area of the electrode, so that even considerable rotation of the electrode relative to the cords does not break the physical contact between it and the vocal cords. The electrode is so designed that rotational placement is not critical, allowing for greater durability and flexibility in use.
