About the NIM EMG Endotracheal Tubes
NIM EMG Endotracheal Tube for nerve monitoring during thyroid surgery
Using a NIM Probe for nerve monitoring during thyroidectomy
Why Monitor During Thyroidectomy and Parathyroidectomy Procedures?
Visually identifying the recurrent laryngeal or vagus nerves during thyroid and parathyroid surgery can be difficult in areas with poor visibility, even with a detailed knowledge of anatomy and surgical skill. In fact, research has shown that the perceived incidence of paresis is lower than the actual rate of nerve damage in thyroid procedures.1 Studies indicate that intraoperative nerve monitoring of the recurrent laryngeal nerve is recommended as a risk-minimizing tool.2-6
Our innovative NIM® EMG Endotracheal Tubes provide both an open airway for patient ventilation and intraoperative nerve monitoring capability. Bipolar stainless steel contact electrodes embedded in the endotracheal tube monitor the nerves in both vocal cords. If nerve function changes, the NIM nerve monitoring system provides visual and audible warnings to alert you and help reduce the risk of injury to your patient.
Together with the NIM Nerve Monitoring System, a properly positioned NIM EMG Endotracheal Tube can reduce the risk of injury to your patient by helping you to:
- Identify the recurrent laryngeal or vagus nerves
- Control manipulation during dissection
- Verify the integrity of the nerve prior to surgical closure
Only NIM EMG Endotracheal Tubes are clinically proven and validated for use with our NIM nerve monitoring systems.
Surgical Applications for the NIM EMG Endotracheal Tube

About the Stim Bur Guard for Otologic Procedures
Integrated Facial Nerve Monitoring
Stim Bur Guard for integrated nerve monitoring during otologic procedures with the Visao Otologic Drill and NIM Nerve Monitoring System*
The innovative Stim Bur Guard for the Visao® High-Speed Otologic Drill is the first and only commercially available surgical tool that combines an electric drill with stimulation for nerve monitoring. It works with our NIM® Nerve Monitoring System to alert you of the bur’s proximity to the facial nerve and help reduce the risk of patient injury during otologic procedures.*
The Stim Bur Guard provides stimulating current to our Medtronic otologic burs in both static and dynamic modes. Stimulating the nerve while the bur is in use can offer approximately 1-3 mm of advance warning of facial nerve proximity. If nerve function changes, the NIM system provides visual and audible warnings to alert you. By reducing the risk of nerve damage during otologic procedures, the innovative Stim Bur Guard helps provide additional peace-of-mind for you and your patients.
The Stim Bur Guard can be used with or without irrigation, and numerous bur types are available. See the ENT Product Catalog for a complete selection of our otologic burs.
* Nerve monitoring capability provided by NIM-Response® or NIM-Neuro® Nerve Monitoring Systems, models 2.0 and later. Must be used with Visao® High-Speed Otologic Drill and Integrated Power Console (IPC®) System.
