Do you sometimes experience slight changes in your hearing? Or is your little one suffering from an ear problem? Then today we are going to talk about something that may be very important to you. That is a test called Tympanometry . This can see how well your middle ear is working. Simply put, it is done by measuring how the eardrum moves.
What is Tympanometry? Why is it important?
Think of your ear as a little musical instrument. It has three parts: the outer ear, the middle ear, and the inner ear . Sound enters your outer ear as energy, or vibrations. This energy hits the eardrum in your middle ear. It then travels through your inner ear to your brain. That's where this energy is converted into electrical signals, and your brain says, "Hey, this is sound."
Simply put, your middle ear is like an important junction on the road where sound travels. If there is a problem somewhere along this road, we may experience hearing loss. This is what this tympanometry test helps us find out about problems in the middle ear. It can identify problems in the path that carries sound from the ear canal to the inner ear.
When is this Tympanometry test necessary?
This test is sometimes done as part of a routine hearing test . It is also used to determine the cause of your hearing loss if there is a problem with your middle ear. This can help your doctor determine why you are not hearing. It can also help determine if you would benefit from hearing aids or if you need other treatment.
This test is especially common among young children . But it can be used to help anyone of any age find out where in the ear a hearing problem is starting. Did you know that young children often have watery fluid in their ears. If it's not treated properly, it can lead to hearing problems.
Who is doing this test?
This test is performed by an audiologist , a doctorate-level health care professional who helps people with hearing and balance problems. They help prevent, diagnose, and treat ear problems that affect both children and adults.
How does the Tympanometry test work?
This test uses a device called a tympanometer . This device has a small probe . The audiologist inserts this probe into your ear. This probe has three holes:
- Air port: This sends air into your ear canal.
- Speaker port: This sends a certain amount of sound energy to your eardrum.
- Microphone port: This is where information is recorded about how your eardrum moves in response to air pressure and sound intensity.
Sounds simple, right? This little device can detect big problems in our ears.
How is this test done? Can you explain a little bit?
Don't worry, this is very simple. All you have to do is sit upright in a chair. If you have a small child, you can do this by holding them on your parent's lap. The most important thing is to not move, smile, talk, sneeze, or swallow during the test. Doing these things can interfere with the test results.
Okay, now let's see what happens step by step:
1. First, the audiologist will perform a basic examination called an otoscopy . This involves looking inside your ear with a small instrument called an otoscope , which has a light. This allows you to clearly see your ear canal, eardrum, and other parts of the middle ear.
2. Then the tympanometer probe is inserted into the ear. The tip of this probe is shaped like an earplug . It creates an airtight seal inside your ear canal.
3. Now, as the probe blows air into your ear, a slow, steady sound is emitted. You will feel the pressure inside your ear increase. It may feel like your ears are about to "pop" when you're on a plane .
4. The microphone on the probe records how your eardrum moved in response to the sound and air pressure.
5. Finally, the tympanometer produces a graph called a tympanogram . This is what shows how your eardrum moved.
Are there any risks with this test?
In fact, tympanometry is not a very risky test . There are usually no side effects. However, young children may be a little nervous because they do not fully understand what is happening at this time. Therefore, it is better to prepare them for this in advance. Depending on the age of the child, you can explain what is happening, or you can act it out like a doll.
What are the results like? What do they tell us?
The shape of the tympanogram chart can tell you whether your results are normal or abnormal.
Normal Results
Normal results mean that your eardrum is moving normally. If your eardrum is moving normally, the line on the graph will look like a hill, or a curved peak . If your eardrum is working properly, this peak will be located on the graph at a value between -100 and +100 dekapascals (daPa) . A dekapascal (daPa) is a unit of measurement for the air pressure inside your ear canal.
What does an abnormal tympanogram mean?
An experienced audiologist can study the curve on the chart and tell you the cause if the eardrum is showing signs of stiffness.
An abnormal tympanogram can mean things like:
- A blockage or fluid buildup in the middle ear (this is the most common).
- Scarring of the eardrum due to a previous infection or fluid.
- Blockage or blockage of the Eustachian tubes (these are the tubes that open and close to regulate air pressure inside the ear).
- Complete or partial blockage of the ear canal due to earwax.
- Growth of lumps in the middle ear.
- The small bones (ossicles) in the middle ear do not move properly.
- Having a perforated eardrum (or having had a perforated eardrum before).
Depending on the cause of your eardrum's inability to move properly, your audiologist may refer you to an ear, nose, and throat (ENT) physician . Common causes, such as fluid buildup, can often be easily treated. It's important to note, however, that tympanometry cannot tell the difference between normal fluid in the ear and an infected fluid.
What is the difference between Audiometry and Tympanometry?
Both of these tests measure two things. Audiometry measures how well you can hear sounds. That is, how well you can distinguish between different types of sounds (pitches), and how well you can hear soft and loud sounds. Tympanometry measures the movement of your eardrum and how well your middle ear is working. Both of these tests help your doctor diagnose hearing problems.
Finally, remember this ! (Take-Home Message)
So, Tympanometry is a quick, easy test that shows how well your middle ear is working. You don't need to do any special preparation for it. After the test, your audiologist can reassure you that your middle ear is working well. Or, if there's something else that's interfering with your hearing, they can recommend further tests or treatments to correct it.
Therefore, if you feel any discomfort in your ears or a change in your hearing, don't be afraid to see a doctor and talk about this type of test. The sooner you identify the problem, the sooner you can find a solution!
