Recurrent Laryngeal Nerve Monitoring (RLN) is used during thyroid, parathyroid, and other neck surgeries to protect the recurrent laryngeal nerve, crucial for voice and swallowing functions. Continuous real-time monitoring of the nerve’s electrical activity through electrodes placed in the larynx’s muscles helps surgeons identify and preserve the nerve, reducing the risk of vocal cord paralysis and ensuring post-surgery speech and swallowing functions maintenance. Recurrent laryngeal nerve monitoring is essential for enhancing patient safety and improving surgical outcomes by minimising potential nerve damage.
