Laryngoscopy is an exam that lets our ENT Doctors see the back of your throat and your voice box (larynx) using a tool called a Laryngoscope. A Laryngoscopy will be performed for the following reasons:
- to find the cause of voice problems, such as breathy, hoarse, weak or no voice
- to find the cause of pain in your throat or ear
- to find the cause for problems such as difficulty in swallowing, a lump in the throat feeling, or bloody mucus
- to check injuries to the throat
- to check for breathing difficulties such as narrowing of the throat or blockages in the airway
There are two different types of laryngoscopy – Indirect and Direct.
This procedure is done in the office using a fiber-optic scope through your nose or mouth. First you will have numbing spray to your nose and/or mouth to provide more comfort to you. You will be asked to sit up straight, stick out your tongue and possibly make some eee or ahhh sounds. This type of laryngoscopy is diagnostic and usually no biopsies are done with this procedure.
Direct laryngoscopy lets us see more directly at your throat and voice box in the operating room while you are asleep under general anesthesia. These are rigid scopes, which are often used in surgery to remove foreign objects, perform biopsies, remove polyps or perform laser treatments. It may also be used to help find cancer of the voice box.
How To Prepare
For the in-office procedure using a flexible scope, please do not to eat or drink anything before the procedure. Although numbing medication is used, some patients with a strong gag reflex may have trouble and we want to prevent vomiting. If you wear dentures, you will just need to remove them before the examination.
If a rigid scope is necessary, it will be performed under general anesthesia. Our ENT Doctors will want to know if you:
- Are allergic to any medicines, including anesthetics
- Are taking any medications or herbal drugs
- Have bleeding problems or take any blood-thinning medicine
- Have a history of heart problems
- Are pregnant or might be pregnant
- Have had surgery or radiation treatments to your mouth or throat
Prepare as you would for a surgery. Be sure NOT to eat or drink for 8 hours before the procedure. Remove all jewelry, dentures, glasses, and use the restroom. Also plan to have someone drive you home following the procedure.
Once you are asleep, our ENT Doctors will place the scope in your mouth and down your throat to perform your treatment. After the procedure, you will be in recovery until you are fully awake and able to swallow.
