Doctors to look at the larynx (voice box) and the glottis of a patient use a Laryngoscope. Ear, nose and throat doctors check the health of the thyroid gland and the general condition of the throat primarily uses the device. A Laryngoscope is a medical instrument used for looking at the vocal chords and the glottis, which are the spaces between the vocal chords.


Benjamin Guy Babington invented The Laryngoscope in 1830. This invention, along with other innovations by Babington, is primarily responsible for Babington's appointment as a physician to Guy's Hospital in London in 1837.


The Laryngoscope is a long, plastic tube with a light at the closing stages. The tube is flexible to allow for easy insertion into the throat, as the light at the end allows the physician to view easily the inner throat. For the reason that the tube can be easily inserted into the gullet, the patient can be conscious through the whole procedure, thus the vocal box can be observed while the patient is singing or talking.


There are many types of Laryngoscope, most with different uses than the standard Laryngoscopes. For an instant, an inflexible Laryngoscope contains a blade on its end and used for intubation. A straight Laryngoscope is a much less flexible version of the original Laryngoscope. This type provides an easier way to view the throat; however can easily gag conscious patients.


The root words for "Laryngoscope" are the words "laryngo" for larynx and the Greek word "skopeo," which means, "to inspect."

Laryngoscope is a flexible tube, equipped with a special blade and a battery system, used to examine the larynx. It is inserted through the patient's mouth into the upper airway. Design of blade and lighting capacities affect the performance of laryngoscope, especially its delivery and illumination.


  1. Is used in intubation during general anesthesia or for mechanical ventilation of the airways.

  2. Helps to define specific causes of voice-related problems: absence of voice, weak voice or hoarse voice.

  3. Discerns what causes swallowing problems.

  4. Detects exact causes of pain in ear and throat area.

  5. Detects obtrusive masses in the airway.

  6. Detects throat injuries.

Blade designs

Medical equipment design plays a crucial role in performing its primary functions successfully. There are multi-shaped Laryngoscope blade designs, which enable different functions of this convenient medical device.

The first Laryngoscopes used in medical practice had straight "Magill blade". They are still widely applied in veterinary. Such type of blade with time was substituted with two other models. These are - the straight blade (the most popular is the Miller blade) and the curved blade (the most popular is the Macintosh blade).

All blades are currently available in various sizes:

  1. Large adult.

  2. Small adult.

  3. Infant.

  4. Neonate.

  5. Paediatric.

Other blades include Philips, Sykes, Wisconsin, Roberts haw, etc. Some of them are equipped with special accessories. For example, a mirror on Laryngoscope is used for obtaining a broader view of the area. It is also possible to deliver oxygen to the airway through a special port in Laryngoscope structure. If you are shopping for a Laryngoscope, do some research online before making your final choice? Laryngoscope comes in a variety of models and can include different features. It is a good idea to research the differences between various models before making a decision. Quality is a very important factor to consider when you are buying a Laryngoscope.
