Clear Visuals: What to Look for In Video Laryngoscopes

Video Laryngoscope in Surgery

Healthcare facility directors know the importance of having cutting-edge equipment for their providers. Video laryngoscopes offer a new alternative for airway intubation. This tool also has many therapeutic advantages during neck and head procedures.

This tool gives medical providers a clear, unobstructed view of the mouth and throat. This allows them to quickly treat and diagnose patient conditions. Keep reading to learn more about video laryngoscopes.

Newer video laryngoscopes can provide recording and still image output to a variety of systems for study, diagnostics, and historical records.

Types of Laryngoscopes

Providers use laryngoscopes to perform several different procedures. This tool allows the physician to examine different parts of the throat using various laryngeal views. This includes the back of the throat, larynx (voice box), and vocal cords.

There are several different approaches to performing this procedure. The following gives a brief overview.

Indirect Laryngoscopy

The indirect method involves the use of a mirror and light to view the throat area. Some physicians wear headgear with a light mounted on it to free up their hands.

Providers may do this in their office after numbing the back of the throat. This approach isn’t used as often since the introduction of the flexible laryngoscope.


A fiberoptic laryngoscope is a small, flexible telescopic instrument. The provider slides this through the nose and down into the throat. This approach is often used to examine the larynx and takes less than one minute.

Direct Laryngoscopy

A flexible or stiff laryngoscope is inserted into the back of the throat. Most patients receive anesthesia for this procedure.

Video Laryngoscopy

The newest instrument on the market is the video laryngoscope. Unlike other similar procedures, this approach includes a video screen.

Reasons for Performing a Laryngoscopy

This procedure is now performed for a wide variety of reasons. It’s used during surgery to keep the airway open after sedating the patient.

This is commonly called intubation. Intubation is also used to provide respiratory support with a mechanical ventilator.

Another key reason for performing a laryngoscopy is to remove foreign objects. Patients also undergo this procedure to diagnose ongoing problems. Examples include the following.

  • Difficulty speaking, swallowing, or breathing
  • Ongoing cough, throat pain, bloody cough, or bad breath
  • Prolonged hoarseness, laryngitis, breathy, or weak voice
  • Ongoing earaches
  • Examination of a mass detected in the throat
  • Removal of throat polyps

This procedure is also used to look for injuries, narrowing, or blockages of the throat. The provider can take tissue samples (biopsies) and perform laser treatments as well.

Possible Risks Associated with Laryngoscopy

The success of any laryngoscopy depends on the provider’s experience and the device. It’s key to choose the correct blade for the patient’s mouth and throat size. Users must also properly shape the endotracheal tube when intubating.

While laryngoscopy is considered safe, risks may arise. It’s important for the provider to demonstrate proficiency before performing this procedure.

During video laryngoscopy, providers should develop a habit of changing their focus. Alternate between looking at the screen and in the mouth. This decreases the risk of complications associated with trauma.

Different laryngoscopic procedures carry specific risks for complication. A general overview of potential adverse events includes:

  • Allergic reactions to the medications used for anesthesia
  • Heart problems
  • Difficulty breathing caused by vocal cord spasms
  • Infection
  • Bleeding (minor to major) in the throat
  • Blood clots
  • Mouth and/or throat ulcers
  • Nosebleeds, especially with nasolaryngoscopy
  • Oropharyngeal trauma to the tongue, lips, or teeth
  • Hoarseness
  • Sore throat or mouth pain
  • Vomiting or gagging

Patients who smoke may have an increased risk of complications. The physician or nurse will provide specific instructions for after-care. If the patient experiences any of these problems, they should call their provider.
