Laryngoscopy: Procedure, Types, Medical Uses and How It Works

What Is A Laryngoscopy?

A laryngoscopy is a medical procedure used to look at your voice box (larynx), vocal cords, and the area around them. It allows your doctor to diagnose issues such as throat pain, hoarseness, or difficulty swallowing. A thin, flexible or rigid instrument called a laryngoscope is used to carefully examine the throat area. 

This procedure helps identify infections, growths, or abnormalities. It can be done in a clinic or hospital, and it’s generally quick and safe. Knowing what to expect can help ease any worries you may have.

When Would I Need A Laryngoscopy?

Your doctor may recommend a laryngoscopy for several reasons. It’s often used when you’re experiencing ongoing throat symptoms that aren’t going away with regular treatment.

Some common reasons include:

• Persistent hoarseness or voice changes
• Difficulty swallowing or a feeling of something stuck in your throat
• Long-lasting sore throat or cough
• Unexplained ear pain
• A lump or swelling in your neck
• Suspected infections or inflammation of the throat
• To check for signs of cancer or monitor existing conditions
• To help remove foreign objects stuck in the throat
• Before surgery involving the throat or upper airway

Modern tools and well-designed laryngoscope parts can help to ensure a thorough examination and better comfort during the procedure. This gives your doctor a clear view of the problem, allowing for quicker and more accurate treatment.

Different Types Of Laryngoscopy

There are several types of laryngoscope procedures used depending on your symptoms and the purpose of the exam. Each type allows your doctor to see the throat and voice box in a slightly different way.

Here are the main types:

• Indirect laryngoscopy: This is the most traditional method. Your doctor uses a small mirror, held at the back of your throat, to look at the larynx. It’s often done in a clinic and doesn’t require anaesthesia. It’s quick and non-invasive, but it doesn’t give a detailed view.
• Direct laryngoscopy: This is more advanced. A rigid or flexible laryngoscope is inserted through your nose or mouth. It allows a closer look at deeper parts of your throat and larynx. This is usually done under local or general anaesthetic, depending on your comfort and the purpose of the test.
• Flexible laryngoscopy: A thin, bendable scope is passed through your nose. It’s commonly used and causes minimal discomfort. It provides excellent images and can be done in an outpatient setting.
• Rigid laryngoscopy: This method uses a firm tube, usually performed in an operating room under general anaesthetic. It allows for biopsies and removal of foreign bodies or growths.

Each method has its benefits. Your doctor will choose the most suitable one based on your needs.

Who Performs Laryngoscopies?

Laryngoscopies are performed by highly trained specialists. You will be in safe hands throughout the process.

The following professionals typically carry out this procedure:

• ENT specialists (Ear, Nose, and Throat doctors): Also called otolaryngologists, they most commonly perform this test. They are experts in managing conditions affecting your throat, voice, and airway.
• Anaesthetists: In surgical settings, they may use a laryngoscope to help place a breathing tube before anaesthesia. This ensures your airway remains open during surgery.
• Pulmonologists or gastroenterologists: In some cases, other specialists may be involved if your symptoms relate to the lungs or digestive tract.

The range of laryngoscope uses varies across medical fields, from diagnostic examinations to airway management during surgery.

Moreover, you’ll be informed in advance about who will be doing your procedure and what to expect from them.

Test Details

A laryngoscopy is a detailed examination that can be comfortably done with a proper preparation and support. It involves a few simple steps before, during, and after the procedure to ensure everything goes smoothly.

What Happens Before My Laryngoscopy?

Before your laryngoscopy, your doctor will explain why it’s being done and how it will help. You may be asked about your symptoms and medical history.

Here’s what to expect:

• Discussion of symptoms: Share if you are going through throat pain, hoarseness, or swallowing problems.
• Medication review: Let your doctor know about any medicines or allergies you have.
• Instructions about eating or drinking: For certain types, especially direct laryngoscopy, you may need to avoid food or drink for a few hours.
• Consent form: You’ll be asked to give written permission for the procedure.
• Relaxation guidance: You’ll be reassured and guided to stay calm before it begins.

Your comfort and safety are always prioritised.

What Happens During My Laryngoscopy?

The exact steps depend on the type of laryngoscopy you’re having, but the process is generally simple and well-tolerated.

Here’s what usually happens:

• Positioning: You’ll sit in a chair or lie down comfortably.
• Local anaesthetic: A spray or gel may be applied to numb your throat or nose.
• Inserting the scope: A flexible or rigid laryngoscope will be carefully inserted through your nose or mouth.
• Examination: Your doctor will examine your larynx and vocal cords. If needed, photos or videos may be taken.
• Biopsy (if needed): Small samples might be collected if there’s anything unusual.

The test typically takes just a few minutes and is not painful, though it may feel a little strange.

What Happens After My Laryngoscopy?

After your procedure, you will be monitored for a short period to ensure you are okay, especially if sedation or anaesthetic was used.

Here’s what happens next:

• Observation: You may stay in a recovery room for a short period.
• Eating and drinking: You’ll be advised to wait until the numbness wears off before eating or drinking to avoid choking.
• Voice rest: You may be asked to rest your voice for a few hours.
• Return to normal activities: Most people can go back to their regular routine the same day.
• Follow-up: You’ll be told when to expect your results and any further steps.

If you feel unwell or have concerns, don’t hesitate to contact your healthcare provider.

What Are Laryngoscopy Complications Or Side Effects?

Laryngoscopy is generally safe, but like any medical test, there can be minor side effects. It’s important to be aware of them, but remember — serious issues are rare.

Some possible side effects include:

• Sore throat: You may have mild discomfort or a scratchy feeling for a day or two.
• Hoarseness: Your voice might sound different temporarily.
• Coughing or gagging: This is common during or after the test but usually settles quickly.
• Nosebleeds: In rare cases, the scope might irritate your nasal passage.
• Allergic reaction: Very rarely, you might react to the anaesthetic spray or sedative.
• Injury or bleeding: Extremely rare but possible, especially if a biopsy is taken.

Your doctor will talk through any risks with you and provide guidance on when to seek help. Rest assured, most people recover quickly and comfortably.

When Should I Have Results From My Laryngoscopy?

Waiting for test results can be stressful, but your healthcare team will keep you informed.

Here’s what to expect:

• Immediate feedback: In many cases, your doctor may tell you the results right after the test if everything looks normal.
• Biopsy results: If tissue was taken, lab results might take a few days to a week.
• Follow-up appointment: You’ll be scheduled to review your results and next steps.
• Contacting you: If anything urgent is found, your doctor will reach out sooner.
