What to Expect

Prior to Procedure

Your doctor may do some of the following:
Leading up to your procedure:
  • Arrange for a ride to and from the procedure if a general anesthetic or sedation is given.
  • If you will have general anesthesia, you will probably be told not to eat or drink anything for eight hours before the exam. For office procedures under local anesthesia, there is no need to fast.
Talk to your doctor about your medications. You may be asked to stop taking some medications up to one week before the procedure.


Local or general anesthesia may be used for a laryngoscopy. Local anesthesia will numb the throat. With general anesthesia, you will be asleep.

Description of the Procedure

During either type of laryngoscopy, photographs may be taken.
Indirect Laryngoscopy
You will sit up straight in a high-back chair. A headrest will push your head and jaw forward. The anesthesia will be sprayed into your throat. Your tongue will be covered with gauze and held by the doctor. You will then need to breathe through your mouth as if panting. A warm mirror will be held at the back of the throat. The doctor will ask you to make a specific sound and watch the larynx. If there is a foreign object, such as a chicken bone, it can be removed.
Direct Fiberoptic Laryngoscopy
The direct method is most often done after the indirect method. The direct method will allow the doctor to see a greater area. The direct method may also be used if your gag reflex did not allow a thorough exam during the indirect method. A special scope will be inserted through your nose or mouth and into your throat. The larynx will be examined through an eyepiece on the scope. The doctor may then collect specimens, remove growths, or retrieve a foreign object trapped in the throat. This method is often done in the operating room under general anesthesia or in the office under local anesthesia.

How Long Will It Take?

An indirect laryngoscopy only takes a few minutes. A direct laryngoscopy takes about 5–45 minutes, depending on the problem.

Will It Hurt?

Anesthesia will prevent pain during the procedure. With a direct method, you may have a sore throat for a few days if a biopsy was done.

Postoperative Care

If any tissue was removed, it will be sent to be examined.
Be sure to follow your doctor's instructions, which may include:
  • Do not smoke for 24 hours after the procedure. Smoke irritates the throat.
  • Do not try to swallow until your gag reflex returns. Spit out saliva and secretions. The gag reflex should return in about two hours. At this time, throat lozenges or a liquid gargle will help decrease hoarseness and throat irritation. Drinking water is encouraged.
  • If a biopsy was taken, avoid clearing your throat or coughing.
Ask your doctor about when it is safe to shower, bathe, or soak in water.
The doctor may discuss the results and treatment options or refer you to a specialist. Biopsy results may take about 3-5 days.
