Head and Neck Surgery
Head and Neck Surgery
We offer powered and manual head and neck surgery products to help otolaryngologists, endocrine, and general surgeons treat a variety of conditions.
About Head and Neck Surgery
Medtronic offers a broad portfolio of head and neck surgery products to help otolaryngologists, endocrine, and general surgeons treat a variety of conditions in adult and pediatric patients, such as:
- Thyroid and parathyroid disorders
- Head and neck cancer
- Sinus disease
- Tonsil and adenoid conditions
- Sleep-disordered breathing
- Otologic and neurotologic disease
- Speech and airway disorders
- Lymph node biopsy
- Tumor removal
Some of our key head and neck surgery products include the items below.
Powered ENT Instruments
Our Powered ENT Instruments include the multispecialty Integrated Power Console, Straightshot® M4 Microdebrider, Indigo™ Otologic Drill, Visao® High-Speed Otologic Drill, and Legend Stylus® Drill. During head and neck surgery, these tools can facilitate more precise tissue removal, visibility, and surgical access. We also offer the most comprehensive selection of application-specific blades and burs for head and neck surgery.
NIM Intraoperative Nerve Monitoring Systems
Our NIM® Nerve Monitoring Systems enable surgeons to identify and confirm motor nerve function and monitor major motor nerves during head and neck surgery, such as thyroidectomies, as well as other procedures performed by ENT, endocrine, and general surgeons. If there is a change in nerve function, the NIM System may provide visual and audible warnings to alert the surgeon. This helps reduce the risk of intraoperative nerve damage, improving safety and peace of mind for both surgeons and patients.
NIM EMG Endotracheal Tubes
Studies indicate that intraoperative nerve monitoring of the recurrent laryngeal nerve is recommended as a risk-minimizing tool during neck dissections, including thyroid surgery.1-6 Our NIM EMG Endotracheal Tubes provide an open airway for patient ventilation and intraoperative monitoring of both vocal cords.
Used with the NIM System, a properly positioned NIM EMG Endotracheal Tube can reduce the risk of injury to the patient during thyroid surgery by helping the surgeon to:
- Identify the recurrent laryngeal, vagus, or other motor nerves at risk
- Control manipulation during dissection
- Verify the integrity of the nerve prior to surgical closure
Fusion ENT Navigation System
Our Fusion® ENT Navigation System is an electromagnetic image-guided surgery system that offers reliable accuracy, ease of use, and expandability. Image-guided surgery with the Fusion system can help you navigate each patient’s unique anatomy for safer, more thorough head and neck procedures when operating near important structures such as the brain, orbit, or carotid artery. The Fusion system allows customization for each surgeon, including procedure-specific pathways for FESS and lateral or anterior skull base.

Thyroid Surgery: Why Monitor?
Clinical Evidence: Injury to the RLN
It is a serious complication of thyroid surgery, yet the rate of recurrent laryngeal nerve (RLN) damage is underestimated.1-6 Clinical evidence shows the benefits of intraoperative nerve monitoring (IONM) of the RLN for nerve preservation and as a risk-minimizing tool during neck dissections, including thyroid surgery.1-4,7-15
Anatomical Variants of the RLN
Studies indicate anatomical variants are an important factor in nerve injury. With more than 25 anatomical variants of the RLN, visual identification can be difficult--even for experienced surgeons. Variations cannot be predicted preoperatively; nor does visual identification always prevent postoperative paralysis.12
"Invisible" Injury
Most RLN damage is caused by invisible injury from traction, pressure, and thermal devices.3,4,12,14 Berry's ligament is particularly vulnerable and a common site of invisible injury. IONM can assess true RLN functionality when the nerve appears visually intact.3,4
A Valuable Surgical Adjunct
IONM is not a substitute for a detailed knowledge of anatomy or surgical skill; it is a valuable surgical adjunct to help surgeons:
- Locate, confirm, and map the nerves. Identifying the RLN has been shown to reduce the rate of RLN palsy.
- Verify and monitor nerve integrity. IONM enables surgeons to verify nerve integrity before and after dissection, monitor EMG activity to help control manipulation during dissection, obtain real-time feedback about nerve function, detect invisible RLN insults,3-4 and perform minimally invasive approaches with added confidence and precision.
NIM Systems for Nerve Monitoring
Based on over 20 years of nerve monitoring experience, the NIM-Response® 3.0 is an innovative nerve integrity monitor that can provide additional patient safety and physician peace of mind. The NIM® 3.0 offers an intuitive touchscreen interface, monitoring through bipolar cautery, artifact detection, and color-coded placement guides. Use it with our NIM TriVantage® EMG Endotracheal Tube and APS® Electrode during thyroid surgery or other head and neck surgery procedures.
NIM EMG Endotracheal Tubes
The NIM TriVantage EMG Endotracheal Tube provides an open airway and intraoperative nerve monitoring of both vocal cords. It features smooth conductive silver ink electrodes, an enhanced EMG response with fewer false positives, and reduced sensitivity to movement or rotation.
APS Electrode
Used with the NIM 3.0, the APS (Automatic Periodic Stimulation) Electrode enables early detection and warning of a change in nerve function. This allows the surgeon to take immediate corrective action to prevent potential injury.16-17 It's placed on the vagus nerve and delivers continuous low-level stimulation. A baseline of nerve function is obtained and subsequent EMG responses are monitored and charted in real time.
Why Use APS Monitoring? Nerves can be at risk in between stimulations due to surgical incision, blind trauma caused by manipulation and stretching during tumor/thyroid removal, and cumulative trauma or damage that may result in neuropraxia.
