What Is Laryngoscopy? A tiny gadget is occasionally used by doctors to examine your throat and larynx, or voice box. Laryngoscopy is the name for this procedure. They might do this to figure out why you have a cough or sore throat, to locate and remove something lodged in your throat, or to take tissue samples to examine later. https://www.facebook.com/BLXMedical History Benjamin Guy Babington (1794–1866), who termed his device the “glottis-cope,” is credited by some historians (for example, Morell Mackenzie) with the development of the laryngoscope. Other early physicians who used mouth mirrors to evaluate the oropharynx and hypopharynx included Philipp von Bozzini (1773–1809) and Garignard de la Tour. Manuel Garca (1805–1906), a vocal pedagogics, was the first to observe the functional glottis and larynx in a living human in 1854. Garca devised a device that made use of two mirrors and the Sun as an external light source. He was able to monitor the working of his own glottis apparatus as well as the highest region of his trachea using this gadget. In 1855, he gave a talk at the Royal Society of London about his findings.

History
Benjamin Guy Babington (1794–1866), who termed his device the
“glottis-cope,” is credited by some historians (for example, Morell Mackenzie)
with the development of the laryngoscope. Other early physicians who used

2. mouth mirrors to evaluate the oropharynx and hypopharynx included Philipp
von Bozzini (1773–1809) and Garignard de la Tour.
Manuel Garca (1805–1906), a vocal pedagogics, was the first to observe the
functional glottis and larynx in a living human in 1854. Garca devised a device
that made use of two mirrors and the Sun as an external light source. He was
able to monitor the working of his own glottis apparatus as well as the highest
region of his trachea using this gadget. In 1855, he gave a talk at the Royal
Society of London about his findings.

3. Until 23 April 1895, when Alfred Kirstein (1863–1922) of Germany revealed
direct visualization of the vocal cords, all previous investigations of the glottis
and larynx had been done with indirect vision (using mirrors). In Berlin,
Kirstein performed the first direct laryngoscopy, using an esophagoscopy he
had adapted for the purpose, which he dubbed an autoscope. The death of
Emperor Frederick III in 1888 is thought to have prompted Kirstein to design
the autoscope.

4. Chevalier Jackson was the first to report a high success rate for using direct
laryngoscopy to intubate the trachea in 1913. Instead of the proximal light
source used by Kirstein, Jackson introduced a redesigned laryngoscope blade
with a light source at the distal tip. This new blade had a component that the
operator could slide out to make place for an endotracheal tube or
bronchoscope to pass through. Henry Harrington Janeway (1873–1921)
published data obtained with a new laryngoscope he had recently created in
the same year. Janeway, an anesthesiologist at New York City’s Bellevue
Hospital, believed that direct intratracheal insufflation of volatile anesthetics
would improve circumstances for nose, mouth, and throat surgery. With this in
mind, he created a laryngoscope that could only be used for tracheal
intubation. Janeway’s design contained a distal light source, similar to
Jackson’s. The incorporation of batteries in the handle, a central slot in the
blade for keeping the tracheal tube in the midline of the oropharynx during

5. intubation, and a tiny curvature to the blade’s distal tip to aid guide the tube
into the glottis were all unique features. Because of the design’s success, it
has since been used in various types of surgery. Janeway was thus a driving
force behind the widespread adoption of direct laryngoscopy and tracheal
intubation in anesthesiology.
What Functions Does My Larynx
Perform?
It assists you in speaking, breathing, and swallowing. It’s located at the rear of
your throat and the top of your trachea, or windpipe. It is home to your vocal
chords, which vibrate to produce sounds when you talk.
A little hand instrument called a laryngoscopy is used by doctors to see into
your larynx and other neighboring regions of your throat, or to place a tube
into your windpipe to help you breathe.
A small video camera is frequently included in modern versions of the gadget.

6. When Should a Laryngoscopy Be
Performed?
It may be performed by your doctor to determine the cause of a persistent
sore throat or to diagnose an ongoing condition such as coughing,
hoarseness, or poor breath. They might also do one when:
Something is caught in your throat.
You’re having difficulty breathing or swallowing.
You’re suffering from an earache that won’t go away.
They must investigate something that could indicate a more serious health
concern, such as cancer.

7. They need to get rid of growth.
Types of Laryngoscopy:
This operation can be performed in a variety of ways by your doctor:
Indirect Laryngoscopy: This is the most basic version. Your doctor examines
your throat with a small mirror and a light. The mirror is mounted on a long
handle, similar to those used by dentists, and is pushed against the roof of
your mouth. To see the picture in the mirror, the doctor shines a light into your
mouth. It takes only 5 to 10 minutes in a doctor’s office.

8. While the exam is being completed, you will be seated in a chair. To numb
your throat, your doctor may spray medication into it. However, having
something stuck in your throat may cause you to vomit.
Direct Fiber-Optic Laryngoscopy: This type of laryngoscopy, also known as
flexible laryngoscopy, is being performed by a large number of specialists.
They utilize a small telescope at the end of a cable that runs up your nose and
down into your throat to do the procedure.
It takes less than ten minutes to complete. You’ll be given a nose numbing
medicine. A decongestant may also be used to open your nasal airways.
Gagging is another typical effect of this surgery.
Direct Laryngoscopy: This is the type that requires the most effort. A
laryngoscope is used to push down your tongue and lift up your epiglottis.

9. That’s the cartilage flap that protects your windpipe. It opens when you
breathe and shuts when you swallow.
This can be done by your doctor to remove tiny growths or tissue samples for
testing. This method can also be used to introduce a tube into the windpipe to
assist someone with breathing during an emergency or surgery.
It can take up to 45 minutes to do a direct laryngoscopy. You’ll be given
general anesthesia, which means you won’t be conscious during the
procedure. Your doctor can remove any growths in your throat or collect a
sample of something that needs to be investigated further.
Laryngoscopy and Nasolaryngoscopy

10. The back of your throat, including your voice box, is examined during a
laryngoscopy (larynx). Your vocal cords are housed in your voice box, which
allows you to talk.
How is the Test Performed?
Laryngoscopy can be performed in a variety of methods:
A small mirror is held at the back of your throat during indirect laryngoscopy.
To examine the throat area, the health care professional shines a light on the

11. mirror. This is a straightforward technique. Most of the time, it can be done
while you are awake at the doctor’s office. It’s possible to use a drug to numb
the back of your throat.
Fiberoptic laryngoscopy (Nasolaryngoscopy): A small flexible telescope is
used. The scope is inserted into your neck through your nose. This is the most
typical method of examining the voice box. For the procedure, you are awake.
Your nose will be sprayed with numbing medication. It usually takes less than
a minute to complete this procedure.

12. A strobe light laryngoscopy is also possible. The use of a strobe light can offer
the provider more information regarding any issues with your voice box.
A laryngoscopy is used in direct laryngoscopy. The device is inserted into the
back of your throat. The tube can be either flexible or rigid. This treatment
allows the doctor to see further down into the throat and extract a foreign
object or tissue sample for biopsy. It is performed under general anesthesia in
a hospital or medical institution, which means you will be unconscious and
pain-free during the procedure.

How to Prepare for the Test?
The sort of laryngoscopy you will have will determine your preparation. You
may be told not to drink or eat anything for several hours before the exam if it
will be done under general anesthesia.

13. How will the Test Feel?
The sort of laryngoscopy used will determine how the test feels.
Gagging can be caused by indirect laryngoscopy with a mirror or stroboscope.
As a result, it is rarely used in children under the age of six or in those who
gag easily.
Children can undergo Fiberoptic laryngoscopy. It may give you a squeezing
sensation and make you feel as if you’re about to sneeze.
Why is the Test Performed?

14. This test can assist your doctor in diagnosing a variety of diseases affecting
the throat and voice box. If you have diabetes, your doctor may suggest this
test:
Breath that doesn’t seem to go away.
Breathing difficulties, including squeaky breathing (stridor).
Cough that has been present for a long time (chronic cough).
Coughing up blood.
Swallowing problems.
An earache that won’t go away.
You have the sensation that something is stuck in your throat.
A smoker’s long-term upper respiratory issue.
Cancer indications and symptoms in a mass in the head or neck.
Continual throbbing in the throat.

15. Hoarseness, a weak voice, a raspy voice, or no voice that lasts longer than
three weeks.
A direct laryngoscopy is another option:
Take a sample of tissue from your throat and examine it under a microscope
(biopsy) Remove any obstructions to the airway (for example, a swallowed a
marble or coin).
Normal Results
The throat, voice box, and vocal cords appear normal in a normal outcome.
What Are the Implications of Abnormal
Results?
It’s possible that abnormal outcomes are caused by:
GERD, or gastro-esophageal reflux disease, can cause redness and edema
of the vocal cords.
Throat cancer or voice box cancer.

16. The vocal chords have nodules.
Polyps (harmless lumps) on the vocal cords.
Inflammation of the esophagus.
The muscle and tissue in the voice box are thinned (presbylaryngis).
Risks
Laryngoscopy is a relatively risk-free operation. The risks vary depending on
the procedure, however they could include:
Anesthesia-induced allergic response, including breathing and cardiac issues.
Infection.
Major bleeding.
Nosebleed.
Vocal cord spasm, resulting in breathing difficulties.

17. Ulcers in the mouth and throat lining An injury to the tongue or lips is a
common occurrence.
Considerations
The use of an indirect mirror laryngoscopy is not recommended:
When it comes to infants or extremely young children.
If you have an infection or swelling of the flap of tissue in front of your voice
box, you have acute epiglottitis.
If you are unable to open your mouth fully.
