Have you ever thought about this little space inside your nose, at the top of your throat? This is what we call the nasopharynx in medical terms. It's like the checkpoint of our respiratory system. Today, let's talk about what the nasopharynx is, what happens in it, and how to protect yourself from the diseases that come with it.
Simply put, your nasopharynx is the top part of your throat (pharynx). Think of it this way, starting behind your nostrils and just above the roof of your mouth. It's a box-shaped passageway of muscles. It's what allows the air we breathe through our noses to travel through our windpipe (trachea) into our lungs.
The nasopharynx is located at the base of our skull, towards the back. Since it is the part of the throat closest to the nose, it is constantly exposed to germs and dust in the air we breathe. That is why upper respiratory infections are so common.
What are the functions of the nasopharynx?
Now let's see what happens in the nasopharynx.
The main thing is to connect the air that comes through the nasal passages to the rest of the respiratory system. To be precise, it's like a bridge that carries air from the nose to the lungs.
Not only that, it also accomplishes several other important tasks:
- It regulates the pressure between the nasopharynx and the middle ear. Do you remember how your ears pop when you climb a mountain? That's because of this connection that the pressure in the ear is balanced when you take a nap.
- It filters out dust, dirt, and germs from the air we breathe, just like a filter.
- It also helps shape the sound of our voice.
What is in the Nasopharynx?
There are several other important structures inside this small space called the nasopharynx.
Eustachian tubes
These are the two tubes that connect our middle ear to the nasopharynx. They are what equalize the pressure in the ear and drain unwanted fluids that accumulate in the ear. When we have a cold, our ears fall out because these tubes become blocked.
Adenoids
Adenoids are glands that are part of our immune system. They are located on the upper and back walls of the nasopharynx. Especially during childhood, these adenoids help protect us from germs such as viruses and bacteria that enter the body. However, they usually shrink and disappear as we grow older.
What are the common conditions that affect the nasopharynx?
Okay, now let's look at some of the common medical conditions that can affect the nasopharynx.
The biggest problem that often affects us is a condition called nasopharyngitis . You may be familiar with this when you hear the word 'common cold' . What happens is that a virus, usually a rhinovirus, enters the nasopharynx and causes the nasal passages and throat to swell.
Other conditions that can affect are:
- Enlarged adenoids: Frequent infections, allergies, or other inflammatory factors can cause the adenoids in young children to swell. This can cause symptoms such as difficulty breathing through the nose, snoring, and mouth breathing.
- Granulomatosis with polyangiitis: This is a rare condition that causes inflammation of the blood vessels in the nasopharynx, lungs, and kidneys.
- Nasopharyngeal cyst: A cyst is a fluid-filled sac. These cysts that form in the nasopharynx often cause no symptoms. However, if they become large and cause symptoms, they may need to be surgically removed.
- Benign nasopharyngeal tumors: These are also rare. Although they do not spread to other parts of the body like cancer, they can grow and cause serious symptoms. An example is a type of tumor called juvenile nasopharyngeal angiofibroma, which occurs in young boys.
- Nasopharyngeal cancer: Nasopharyngeal carcinoma is the most common type of cancer that develops in the nasopharynx. One of the main symptoms of this may be the appearance of a painless lump in the back of the neck.
What are the symptoms of these diseases?
So, if there is a problem with this nasopharynx, what kind of symptoms might we experience?
Commonly seen symptoms
These are often associated with cold-like conditions:
- Cough
- Itchy or watery eyes
- A little tiredness, tiredness
- Runny nose
- Sneezing
- Sore throat
- Frequent ear infections (especially in young children)
- Nasal congestion, feeling like your nose is "blocked"
- Postnasal drip
Things that may be signs of serious conditions
These symptoms are not always a sign of a serious illness, but it is important to seek medical advice if they are present:
- Frequent, severe headaches, sore throats, or nosebleeds
- Vision changes
- Facial pain or numbness
- Ear pain or ringing in the ears
- A lump in the nose, throat, or neck
- Difficulty breathing, speaking, or hearing
What are the methods for examining the nasopharynx?
Well, if you have symptoms like these, how does a doctor diagnose a nasopharynx problem?
There are several tests that are commonly performed:
- Nasopharyngeal swab: You may remember during the Covid pandemic when they used a swab to take a sample of your nose. That's how it works. This can identify viruses and bacteria that cause infections.
- Nasal endoscopy: This involves passing a thin, flexible tube with a camera attached into the nose to examine the nasal passages and sinus cavities. This can help to better see things like swelling and tumors inside.
- Imaging tests: Sometimes tests like X-rays or CT scans are needed to check for any abnormal growths or tumors inside.
What are the treatments?
When it comes to treatment, it depends on the condition.
- Things like colds usually get better on their own in about a week. The key is to drink plenty of water and get some rest.
- If there are bacterial infections, the doctor may prescribe antibiotics .
- If a child's adenoids are enlarged and causing problems such as difficulty breathing, they may need to be removed through a surgery called an adenoidectomy .
- Also, if there are cysts and tumors that are causing symptoms, they will also need to be removed surgically.
- Treatment for nasopharyngeal cancer depends on many factors, such as the individual's medical condition and the stage of the cancer.
How to keep the nasopharynx healthy?
To keep our nasopharynx healthy, the best thing to do is to try to avoid colds and other respiratory infections. What should we do about that?
- Isolate yourself if necessary: Stay away from people who are sick. If you are sick, stay home and distance yourself from others. This is good for you and for others.
- Keep your hands clean: Wash your hands often with soap and water, or use hand sanitizer. It is especially important to wash your hands after coughing, sneezing, blowing your nose, and before preparing food.
- Keep frequently touched surfaces clean: Clean frequently touched surfaces like toys, doorknobs, and telephones and use disinfectant.
- Be polite when coughing or sneezing: If you have to cough or sneeze, keep a distance from others. Cover your mouth and nose with a tissue. If a tissue is not available, cough or sneeze into your elbow. This greatly reduces the spread of germs.
When should you see a doctor?
Okay, so when do we need to see a doctor?
Remember, if you have symptoms of a common cold for more than 10 days, or if you feel that the symptoms are unusual or severe, you should definitely seek medical advice.
See a doctor right away, especially if you have any of the following:
- Chills
- Cold symptoms lasting more than 10 days
- Fever, especially in young children
- Influenza-like symptoms such as fever, body aches, and extreme tiredness
- Frequent headaches, sore throats, or nosebleeds
- A lump in the nose, throat, or neck
- Ear pain or ringing in the ears
- If you feel your symptoms are unusually severe
- If you have difficulty breathing, speaking, or hearing
Things to remember in brief
So, we talked a lot about the nasopharynx.
Although we can't see the nasopharynx, we can feel it when something is wrong with it. Common conditions like colds and swollen adenoids can affect this part of the body. Very rarely, cancer or benign growths can develop here.
Therefore, if you or your child has any pain or unusual symptoms related to the nasopharynx, it is very important to talk to a doctor about it. Especially if the symptoms of a cold do not subside after a week or ten days, you should definitely seek medical advice. To stay healthy, it is good for us to take care of even the little things like this, right?
