What is laryngeal or vocal cord endoscopy?
Vocal cord endoscopy, also known as laryngeal endoscopy, is a procedure that involves the use of an endoscope to examine the vocal cords and surrounding structures. The steps typically include:
- Local Anesthesia: The throat may be locally anesthetized using a spray or a numbing agent to reduce discomfort during the procedure.
- Insertion of the Endoscope: A thin, flexible tube called an endoscope is inserted through the nose or mouth to reach the larynx (voice box) and visualize the vocal cords.
- Examination and Imaging: The endoscope allows the healthcare provider to examine the vocal cords and capture images or videos for a detailed assessment of their function and appearance.
- Diagnostic Evaluation: Based on the examination, the healthcare provider can diagnose various conditions affecting the vocal cords, such as nodules, polyps, inflammation, or other abnormalities.
Vocal cord endoscopy is a valuable tool for evaluating voice-related concerns and disorders. It helps in identifying the cause of voice changes, hoarseness, or difficulties with vocal function. The procedure is generally considered safe and is often used to guide treatment decisions for conditions affecting the vocal cords.
