Have you ever wondered how your voice comes to you? Where does this sound come from when we shout, sing, or talk softly to a friend? And how does that air get to the lungs when we breathe? There is a small but very important organ in our neck that is responsible for all of this. Today we are talking about the larynx, which is one of the heroes of our respiratory system.
What is the Larynx? Where is it located?
Simply put, the larynx is part of our respiratory system. It is like a hollow tube. It is about 4-5 centimeters long and wide. It is the one that makes the way for air to pass from your throat (pharynx) through your trachea (windpipe) to your lungs. Not only that, but it is also the larynx that allows you to make sounds and speak. That is why it is also called the 'voice box' as we all know it.
Your larynx is located in the middle of your neck, just above your windpipe and esophagus. But the amazing thing is, its position changes slightly throughout our lives. Imagine, from the day we are born until about 2 years old, the larynx is a little higher up in your neck. Over time, it gradually moves down and stabilizes in the middle of your neck.
Parts of the larynx and their functions
Our larynx is divided into three main parts:
- The upper part (supraglottis)
- Middle part (glottis)
- The lower part (subglottis)
These three parts contain various things like cartilage, muscles, ligaments, and membranes. However, the vocal cords, which are essential for our voice, are located only in the middle part, which is called the glottis.
- Cartilage: Just as the walls of a house give it a frame and shape, the larynx is given its shape and strength by cartilage.
- Muscles: These muscles help a lot in moving the larynx when we swallow food, helping us breathe, and producing voice.
- Ligaments: Ligaments connect the cartilages together and connect the larynx to surrounding structures such as the hyoid bone and trachea.
- Membranes: These help keep the cartilage in place.
What diseases and problems affect the larynx?
From serious illnesses like cancer to simply overusing your voice, many things can affect our larynx. Let's take a look at some of the most common conditions.
| Condition | Simply put... |
|---|---|
| Acute Laryngitis | A short-term condition caused by fatigue of the vocal cords due to an infection or excessive use of the voice, such as from shouting. |
| Chronic Laryngitis | Laryngitis that lasts more than three weeks. This can be caused by smoking, allergies, and acid reflux. |
| Laryngeal Cancer | The growth of cancer cells in any part of the larynx. |
| Trauma or Injury | The larynx can be damaged by talking, shouting, or singing for long periods of time. It can also be injured by a blow to the neck. |
| Vocal Cord Dysfunction | The vocal cords may not function normally, such as closing incorrectly when breathing. |
| Vocal Cord Lesions | Overuse of the voice can cause non-cancerous nodules, polyps, or fluid-filled cysts on the vocal cords. |
| Vocal Cord Paralysis | One or both vocal cords not moving properly. |
What are the common symptoms of these problems?
There are several common symptoms that occur when there is a problem with the larynx.
- Sore throat or cough
- Voice changes, especially hoarseness
- Feeling pain or other discomfort when swallowing something
Very important: If you have these symptoms for more than two weeks, please see your doctor without delay. It is very important.
Tests to diagnose problems with the larynx
Depending on your symptoms, your doctor may order various tests. Here are some of them.
| Test | What does this do? |
|---|---|
| Throat culture/blood test | Checking for infectious conditions. |
| Imaging tests | Obtaining detailed images of the larynx and surrounding tissues through tests such as MRI, CT scan, or PET scan. |
| Videostroboscopy | Examining the movement of the vocal cords as they vibrate with a special camera. |
| Laryngoscopy | Examination of the larynx by inserting a thin tube with a small camera down the throat. |
| Biopsy | Taking a small piece of tissue from a suspicious area and examining it under a microscope to confirm whether there are cancer cells. |
What are the treatments for diseases of the larynx?
Treatment methods vary depending on the condition. Here is a simple explanation.
| Medical condition | Treatment methods |
|---|---|
| Laryngitis | |
| For infections | Antibiotics or antifungal medications. |
| Laryngeal Cancer | |
| For cancer | Radiation therapy, chemotherapy, immunotherapy, targeted therapy, or laryngectomy. |
| Vocal Cord Dysfunction | |
| To restore functionality | Breathing exercises, speech therapy, Heliox gas. In some severe cases, a tracheostomy may be necessary. |
| Vocal Cord Lesions | |
| To remove tumors and prevent them from coming back | Voice therapy, lifestyle changes, or surgery. |
| Vocal Cord Paralysis | |
| To restore voice and breathing | Voice therapy, filler injections into the vocal cords, surgery to insert a graft into the larynx, or a tracheostomy if breathing difficulties occur. |
How can I keep my larynx healthy?
There are many simple things you can do to take good care of your voice and larynx.
- Reduce your risk of cancer: Avoid tobacco products and cigarette smoke completely. Limit your alcohol intake. These are the main risk factors for laryngeal cancer.
- Reduce your risk of laryngitis: Wash your hands frequently to protect yourself from respiratory infections, stay away from sick people, and drink plenty of water to prevent a dry throat.
- Protect your vocal cords: Don't strain your voice. Avoid shouting or speaking for long periods of time. Some cold and allergy medications can dry out your vocal cords. So be careful if you use such medications. But remember, if it's a medication prescribed by your doctor, you should definitely ask him before stopping it.
Is it possible to speak without a larynx?
Yes, it can be done. But it requires learning new techniques. For example, some people who have had a laryngectomy use an artificial device called an electrolarynx. It is pressed against the throat to help them speak clearly.
Finally, the larynx is an amazing part of our respiratory system that works non-stop. We should be thankful for it every time we talk, sing, and scream. It also helps us breathe and prevents food and drink from going into our lungs. So, take good care of your precious 'voice box' to reduce your risk of infection, cancer, and vocal cord fatigue.
Take-Home Message
- Your larynx is an important organ that is essential for both breathing and speaking.
- If symptoms such as hoarseness or difficulty swallowing persist for more than two weeks, it is important to seek medical advice immediately.
- Smoking and excessive alcohol consumption are major risk factors for laryngeal cancer. You can protect your larynx by avoiding them.
- Avoid overexerting your voice and drink plenty of water to stay hydrated. This will help keep your vocal cords healthy.
- Always consult your doctor for any long-term symptoms.
