Understanding Laryngoscopy: Procedure, Types, and Benefits

Laryngoscopy is a medical procedure that allows your doctor to see your vocal cords and the upper airway in your throat. It is typically performed using a flexible or rigid telescope called a laryngoscope. The scope is inserted through your nose or mouth and guided through your throat to visualize your vocal cords and other structures in your upper airway.
Laryngoscopy can be used to diagnose and treat a variety of conditions, including:
Vocal cord lesions or polyps
Airway narrowing or blockage
Swallowing disorders
Laryngeal cancer
During the procedure, your doctor may also perform other procedures such as biopsy, laser surgery, or vocal cord injection.
There are different types of laryngoscopy, including:
Direct laryngoscopy: This type of laryngoscopy is performed with a rigid scope that is inserted through your mouth and guided through your throat to visualize your vocal cords.
Flexible laryngoscopy: This type of laryngoscopy is performed with a flexible scope that is inserted through your nose or mouth and guided through your throat to visualize your vocal cords.
Video laryngoscopy: This type of laryngoscopy uses a flexible scope with a camera and a screen to visualize your vocal cords.
The procedure is usually done under local anesthesia, which numbs the back of your throat, or sedation, which helps you relax and feel more comfortable during the procedure. The procedure typically takes about 30 minutes to an hour to complete.
After the procedure, you may experience some soreness in your throat and a hoarse voice for a few days. Your doctor will provide you with instructions on how to care for yourself after the procedure.
