Eustachian Tube explained 

Very informative! I was struggling with ETD for years and experienced remarkable relief following the removal of an infected tooth from the offending side. I suggest all persons suffering from this condition have a whole-mouth xray performed to rule out the presence of infections in the oral cavity as a possible factor.

I've always had a trouble understanding the function ad dysfunction of the Eustachian tube, but now your explanation did illuminate it all! So thank you so much.

Thank you soo much for this explanation! This is what general practitioners/nurses do not explain in great detail! Instead (from my personal experience) say a few basic lines as to why patents have this complaint! It really frustrates me how they do not take the time to explain these types of symptoms and everything else that goes along with this condition. Again, thank you once again! It's much appreciated!

Awesome video helping me with my studies in audio, thanks from Australia Keith

I'm not a biology student, but just wanted to know the science behind the ear pressure when diving in deep water, cause it's painful inside the ear. Now it all makes sense. Thankyou.

So what would you recommend to relieve ear pain in infants crying or screaming on airplanes when the pressure changes? It seems from this video that breastfeeding or giving them a warm bottle drink would be the first choices to get them swallowing. For adults with the same equalization problems, a warm drink sipped as the airplane descends or chewing gum to generate saliva should help.

great video! finally understand the eustachian tube function! thank you!

This just answered my question because my ears pop. I had a sinus surgery and currently healing

Whos here in 2021 and THANK YOU FOR THE VIDEO

I have popping sound but doctor not help sayed CT scan normal.but not cheked eust...tube

I'm 30 yrs old and had a sinus infection which turned my eustation tube getting clogged up.

Elastic cartilage 👍

I need help. A week ago when I had cold I yawned and I had sharp pains in and around my ears they popped and then I got the slight hear loss. And I've tried popping my ears by holding nose and blowing, yawning, everything. It's been a week and I still can't hear properly and they won't pop back. Any advice? Should I go see a doctor ?

Thank you so much for this video! I've been experiencing some severe throat/nose itchiness along with some mildly plugged ears, and it has absoultely been driving crazy! I now feel so much more relieved knowing what might be going on inside my body. Thank you, thank you, thank you!

Hi Dr Forwith, can you tell me if I push air through my eustacian tube to equalise my ear drum but if I have a hole in my ear drum, will this produce a whistling or any type of air sound as I would be pushing air out of my ear drum from the inside or middle ear region?

ty the other day i went 2 er & they say my tube has failled told me go bk primary get in get suergery on tube n bones i have hearing lost n family this worries me & before in past dr would say it my imagnation becouse im autistic n they couldnt explane what this ment at leat i know a bit more now

i want you or any persone see the comment and know the answer to reply to me during breast feeding in infants the horizontal poistion isn t perefered which can led to otits media and bottel feeding in infant is not prefered as it can led to otits media i reay want to know how the horizntal poistion can led to otits media and how bottel feeding can led to otits media

I have eustacian tube dysfunction I got to the ent on the 21

hi, do you have a vid on otitis media specifically?

Help! I've had problems with narrow eustachian tubes all of my life. Who is doing surgery to correct this? I've heard of 'stent' and 'balloon' type surgeries, but isn't someone doing a basic "widening" type surgery?

Doctor Keith, I got my ears flushed recently now every time I swallow my ears have a pop / cracking sound... is it seem to a be normal cause? Is this air going through my ET or do I have a ETD? would love some feedback !

Can CPAP therapy cause problems? I notice that I have all the symptoms you describe and an occasional drumming sound which is irregular or I am sensitive of loud sounds and it vibrates now.

It's annoying as heck not being able to hear out of one ear. It's now been like that for 4 weeks. Is there anything doctors can do that can drain or unclog that eustation tube for me? I tried drinking lots of water, saline solution sprays, steroid spray, exercising, staying off sugar, tried naturopathic medicine like Silver and Cats claw, tried lying downwards. I don't know what else to do. It keeps popping and feels clogged up.

We know and years later drs still have no clue how to treat it.

Thank you, much helpful :)

It's been plugged for the last 4 weeks. What should I do??

Thank you!

Please I need help 😔

ty so much!

It's not surprising that a major function of the Eustachian tube is missing from your video presentation. That comes from a misconception by the science community at large regarding how sound works. There's no particular reason why someone who believes that the "longitudinal compression wave" explanation of how sound works is accurate. We can see that explanation in this RU-vid video; The video is an Encyclopedia Britannica film from 1950 (the poster of the video doesn't understand Roman Numerals as the film clearly identifies the copyright as MCML). View the video to about 3:20 of the film. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cK2-6cgqgYA.html In the animated oscillograph there is NO air behind the diaphragm (the place where, in the ear, the Eustachian tube would deliver air so that generally, the same air density would be on bothe sides of the diaphragm. Unfortunately, that is not a trivial point as it goes to the confusion about how sound works at the core concept level by the...well, every last physics genius on planet Earth (so far as I've found). But, I'm not the first to find this error. Another doctor, who also had a strong interest in science, and especially sound, worked through some of these problems. But, he did it at a time when sound technology was just getting started in earnest. He published a book on the topic in the latter part of the 19th century (1887 with a revised edition in 1880). His name was Alexander Wilford Hall. And, a scan of his book is available on the Internet Archive website: archive.org/details/evolutionsoundp00hallgoog/page/n214/mode/1up?view=theater Chapters V and VI, on sound are the applicable chapters. Dr. Hall does not come up with the correct concept of sound either but, he's at least asking the right questions and questioning the right high authorities of the day. ---------------- What's needed for the ear to process sound correctly (which it does whether we understand HOW it does it or not) is for the back side of the eardrum to have a fixed air density which, as you point out in your video, gets updated each time we swallow (I knew that the Eustachian tube had to act as an efficient low pass filter but, didn't know that it was normally closed off most of the time). As a side note, I don't normally hear myself breathe but, if I position my jaw just right an breathe through my nose, it must open up my Eustachian tubes because I can hear my breathing. Then, there has to be a way for the air density at the other side (facing the ear canal) to change in accordance with incoming sound. As Dr. Hall points out and as I've determined independently, the longitudinal compression wave (or any other kind of waves) do not work and in fact have nothing to do with how sound moves the eardrum (although they do a fairly poor job of explaining how the lungs breathe air in and expel air (if you discount the errors in those explanations, too). Dr. Hall tries to make the case for a corpuscular (scintillating corpuscles of sonorous whatever) but, doesn't make a good case for it. He was aware, and mentions Isaac Newton's corpuscular theory of light so I suppose he thought it might also apply to sound (BTW: "photons"" (corpuscles of light) are also a fantasy of the mathematical physicists). As noted earlier, for us to hear sound, there must be, arriving at the eardrum from a sound source, a variation in the number of air particles arriving. It would appear that, in nature, there is an extremely persistent effect of air particles arriving at a surface of the sound source picking up time/position offsets from that surface as it moves through space. Those offsets are faithfully preserved as the air particles collide and pass them on to the next particle...all the way from the source to the sound detector (perhaps the ear or the microphone of a sound recorder). There are railroad tracks that pass about a mile from my house and the train approaches a crossing at about 1.25 miles and I can clearly hear the tone, timbre and other nuances of the train horn after it passes through the air for about 5 seconds. Any longitudinal compression waves would diffuse out within a few feet and NOT take off at the some 750 mph of the speed of sound in air. Of course sound (and other effects) work the same way in water (whales and dolphins and sonar and tidal waves), solids (seismic "waves" and putting your ear to the ground to hear the buffalo) and even the ether (for light, radio and even sound events like the LIGO recordings of colliding stars but, even though the sound is at sound frequencies the propagation through the ether is at light speed). ------------- I had developed my version of how sound works before I was even aware of Dr. Hall so, when I did read his work was amused that both he and I had come up with the same example of a small sound that carries well in the air; a cricket (which he later changed to a locust). salaphysics.com 082522

i also had this n ring in ear since i was 10 im afade i might lose my hearing becouse no one belived me
