Description of the Procedure
There are two methods to do this procedure. Images may be taken during either type.
You will sit in a chair. A headrest will push your head and jaw forward. Your tongue will be covered with gauze and held by the doctor. You will be asked to breathe through your mouth as if you were panting. A warm mirror will be held to the back of the throat. The doctor will ask you to make a certain sound. The larynx will be viewed. Other needed procedures may be done at this time.
The method may be done after the indirect method. It allows the doctor to get a better view. It may also be used if your gag reflex did not allow for an indirect exam. A special scope will be placed through your nose or mouth, then passed into your throat. The larynx will be checked through an eyepiece on the scope or a camera. Other needed procedures may be done at this time.
How Long Will It Take?
The indirect method only takes a few minutes. The direct method takes about 5 to 45 minutes, depending on the problem.
Will It Hurt?
A sore throat is common in the first few days. Medicine and home care help.
