How It Is Done continued...
The scope is put in your nose and then gently moved down into your throat. As the scope is passed down your throat, your doctor may spray more medicine to keep your throat numb during the examination. The doctor may also swab or spray a medicine inside your nose that opens your nasal passages to give a better view of your airway.
Direct rigid laryngoscopy
Before you have a rigid laryngoscopy, remove all your jewelry, dentures, and eyeglasses. You will empty your bladder before the examination. You will be given a cloth or paper gown to wear.
Direct rigid laryngoscopy is done in a surgery room. You will go to sleep (general anesthetic) and not feel the scope in your throat.
You will lie on your back during this procedure. After you are asleep, the rigid laryngoscope is put in your mouth and down your throat. Your doctor will be able to see your voice box (larynx) and vocal cords.
The rigid laryngoscope may also be used to remove foreign objects in the throat, collect tissue samples (biopsy), remove polyps from the vocal cords, or perform laser treatment.
The examination takes 15 to 30 minutes. You may get an ice pack to use on your throat to prevent swelling. After the procedure, you will be watched by a nurse for a few hours until you are fully awake and able to swallow.
- Do not eat or drink anything for about 2 hours after a laryngoscopy or until you are able to swallow without choking. You can then start with sips of water. When you feel ready, you can eat a normal diet.
- Do not clear your throat or cough hard for several hours after the laryngoscopy.
- If your vocal cords were affected during the laryngoscopy, rest your voice completely for 3 days.
- If you speak, do so in your normal tone of voice and do not talk for very long. Whispering or shouting can strain your vocal cords as they are trying to heal.
- You may sound hoarse for about 3 weeks after the laryngoscopy if tissue was removed.
- If nodules or other lesions were removed from your vocal cords, you may have to follow total voice rest (no talking, whispering, or making any other voice sounds) for up to 2 weeks.
