Description

Fiber-optic laryngoscopy is a medical procedure that involves using a flexible fiberoptic endoscope to visualize the larynx, which is the part of the throat containing the vocal cords. This technique is commonly employed in otolaryngology (ear, nose, and throat, or ENT) and is often referred to as flexible laryngoscopy or fiberoptic bronchoscopy. Here's how the procedure generally works: Preparation: Before the procedure, the patient is usually informed about what to expect, and topical anesthesia may be applied to the nasal passages to minimize discomfort. Instrumentation: A flexible fiberoptic endoscope is used for laryngoscopy. This endoscope is a thin, flexible tube with a light source and a camera on the tip. The flexible nature of the endoscope allows it to navigate the curves of the nasal passages and throat. Procedure: The endoscope is inserted through the nasal passages or, in some cases, through the mouth, and advanced down to the larynx. The light source allows the doctor to visualize the structures of the larynx on a monitor. The procedure is usually well-tolerated, and the patient may be asked to perform certain actions, like making specific sounds or swallowing, to assess the function of the vocal cords and other structures. Diagnosis and Treatment: Fiber-optic laryngoscopy is often used to diagnose various conditions affecting the larynx, such as vocal cord nodules, polyps, tumors, infections, and other abnormalities. Additionally, it can be used to guide certain treatments, such as taking biopsies, removing polyps, or injecting medication into specific areas. Post-Procedure: After the procedure, patients might experience some throat discomfort or a mild gag reflex, but these effects typically resolve quickly.
