Laryngoscopy is a slightly intrusive medical examination performed in the larynx (voice box). It allows healthcare professionals to view the vital organ that hosts the vocal cords and is responsible for speaking. However, what exactly does the laryngoscopy procedure detect, and what does it involve?
The following lines explain in depth all the aspects of this examination and present the best laryngoscopes which offer highly accurate and reliable results.
What Is A Laryngoscopy?
As mentioned, a laryngoscopy provides a close and clear view of the larynx’s tissues and internal area. This examination aims to diagnose any health issues related to voice (like hoarseness), throat pain, or swelling.
For instance, conditions involving nodules, polyps, or other abnormal growths like benign or malignant tumours, even infections that may occur in the laryngeal region, are detected during a laryngoscopy procedure.
To perform this examination, the doctor uses a special medical device called a laryngoscope, which they insert into the larynx – via the mouth or the nose in some cases – to get a magnified look at the patient’s throat. Depending on the findings, the healthcare professional then suggests the appropriate treatment.
What Exactly Is a Laryngoscope?
In simple terms, a laryngoscope is a specifically designed tool that helps doctors reach the patient’s larynx and examine it safely and efficiently. Typically, a laryngoscope consists of a rather sharp end and a small bright light to make the whole procedure more effective.
However, some types—modern versions of the classic laryngoscopes—also come with a miniature camera that allows doctors to monitor the laryngeal area through a video screen.
Laryngoscopes, nevertheless, are not only used for diagnostic purposes. They also have several other applications.
What Are Laryngoscopes Used For?
So what other uses do laryngoscopes have?
- They help with airway management during anaesthesia or resuscitation.
- They facilitate intubation procedures when a breathing tube needs to be inserted into the trachea.
- They are used to remove foreign objects from the throat or airway.
As you can see, laryngoscopes are critical medical tools that are indispensable in various medical settings, including a medical simulation lab.
What Types of Laryngoscopy Procedures Exist?
There are two main categories regarding the laryngoscopy procedure. Each of them serves a different purpose and is associated with a different level of complexity.
1. The Indirect Laryngoscopy
First, there is the indirect procedure, which is a simple, noninvasive examination that does not usually need to be done in a clinic.
In such cases, the doctor uses a tongue holder, a small hand-held mirror, and a light source to reflect an image of the throat. This method is effective when assessment of vocal cord movement or detection of visible abnormalities is required.
2. The Direct Laryngoscopy
The other type of laryngoscopy procedure involves a more advanced examination method. In this method, a laryngoscope is inserted through the mouth or nose, in some cases to provide a direct view of the larynx.
This procedure often requires local or even general anaesthesia and is mainly used for biopsies or the removal of foreign bodies.
A sub-category of the direct method is the newly emerged video laryngoscopy, which provides more diagnostic and invasive benefits and uses video laryngoscopes.
Understanding Video Laryngoscopes
Video laryngoscopes are considered a breakthrough in airway management technology—and rightly so. Unlike traditional devices, these tools feature a miniature camera and display screen that provides a live video feed of the patient’s airway.
This enables users to better visualise the larynx’s internal structures and perform intubation more easily and safely, especially in complex airway cases.
In a nutshell, video laryngoscopes:
- Enhance visual clarity.
- Reduce the risk of airway trauma.
- Increase success rates in emergency intubations.
- Allow real-time recording and playback.
What Types of Video Laryngoscopes Are There?
The most common types are:
-
- Channelled Video Laryngoscopes – These have an integrated tube guide, which makes intubation faster and easier. They are ideal for less experienced clinicians or medical students.
- Non-Channelled Video Laryngoscopes—Unlike the previous type, these models require the separate use of a stylet. However, they offer more flexibility in cases of complex airway management.
- Disposable Video Laryngoscopes—In instances where infectious diseases are involved and strict hygiene standards are required, doctors tend to use the single-use version of these devices.
- Paediatric Video Laryngoscopes – These are smaller and ergonomically shaped to suit the needs of children and infants.
- Multi-function Video Laryngoscopes – Finally, there are the versatile types, which combine multiple blade sizes and recording features to suit various medical environments.
How the Laryngoscopy Procedure Works?
In general, all laryngoscopy procedures involve similar steps, which come down to the following:
- Preparation – The doctor may use a local anaesthetic spray to numb the throat. In surgery settings, general anaesthesia is performed.
- Insertion – The medical practitioner gently inserts the laryngoscope through the patient’s mouth or nose.
- Visual Examination – This is the core part of the examination where the doctor inspects the larynx and surrounding tissues, possibly recording video or taking photographs for further analysis if a video laryngoscope is used.
- Additional Procedures – They take place when a biopsy or removal of growths may be needed.
- Completion – After the examination, patients can return home the same day.

FAQs About Laryngoscopy
Is laryngoscopy painful?
No. Direct laryngoscopy, in particular, is performed under local or general anaesthesia. Indirect laryngoscopy, on the other hand, may cause some mild discomfort that resolves right after the examination is over.
How long does a laryngoscopy procedure take?
In the worst-case scenario, it will take around half an hour. For a typical diagnosis, expect it to last around 15 minutes, while if any tissue samples need to be taken, it may take a bit longer.
Are video laryngoscopes more effective than traditional ones?
Yes, because they offer a more precise visualisation, providing doctors with better guidance. They have also scored improved success rates during intubation and have enhanced safety overall.
This is vital in difficult airway situations, in particular.
