Thyroid Surgery
Neuromonitoring in thyroid surgery
Every year, more than 25,000 thyroid surgeries take place in the United Kingdom, highlighting the need to safeguard over 25,000 vocal cord nerves from potential injury.
The Situation
Functionality
Pathological alterations in thyroid glands or tissue scarring due to multiple surgeries can alter the anatomical position of nerves, presenting a challenge to surgeons, especially those with limited experience. There’s a heightened risk of paresis in the vocal cord nerve, the laryngeal recurrent nerve, which can significantly impact the patient’s quality of life.
As a result, intraoperative neuromonitoring (IONM) has emerged as an essential tool in modern thyroid surgery over the past 15 years.

The crucial role of neuromonitoring in thyroid surgeries
The recurrent laryngeal nerve plays a critical role in vocal cord function and lies close to the thyroid, making it vulnerable during thyroid surgery. Neuromonitoring during these procedures, particularly for recurrent laryngeal nerve function, is crucial for reducing the risk of nerve injury, preserving vocal cord function, and enhancing overall surgical outcomes. It serves as a valuable tool to improve the precision and safety of thyroid surgery.
Intraoperative neuromonitoring
Functionality
Intraoperative neuromonitoring involves transmitting small electrical impulses to the nerve using specialized stimulation probes. The intact nerve carries the stimulation to the vocalis muscle, where electromyography measures the resulting muscle action potential, converting it into visual or auditory signals.
Stimulating the vagus nerve enables monitoring of the laryngeal recurrent nerve’s function along its entire length. A single stimulation before and after thyroid resection is sufficient for monitoring purposes.
Continuous neuromonitoring
for ongoing monitoring of the recurrent laryngeal nerve
With continuous stimulation of the vagus nerve seamlessly integrated into the background, surgeons can detect critical signal changes, such as strain on the recurrent laryngeal nerve, before they escalate. Surgeons also have the option to view long-term trend lines of critical parameters like amplitude and latency. Post-operatively, new situations encountered during surgery can be analysed and compared to other cases using saved recorded signals.
Pre-programmed beeps provide alerts, enabling the surgical team to swiftly respond to critical neural function changes.
