Ear infections are not contagious, and most resolve without antibiotics. There are risks inherent with excessive antibiotic use as well as many allergies and negative side effects. Ear tubes require cutting into a healthy membrane, leave scars, have multiple side effects, and frequently don't solve the problem of chronic infections. The anesthesia required for the procedure carries its own risks. With these negatives in mind and knowing that the body already has a tube designed to do the same thing without the risks why are more efforts not made to improve their function? Why is our current treatment standard despite the known risks, when other options are obviously still unexplored. There is not enough research done on many treatments such as balloon inflation as cited by the chochrane review (http://www.bibliotecacochrane.com/pdf/CD006285.pdf) and stents which has studies both ways.

Here are some of the many sites that I have already visited that did not answer the question, but raised more, if there is better or further information I would like to see it: http://thechart.blogs.cnn.com/2013/07/01/should-your-child-get-ear-tubes/

    What sources say that ear tubes (I guess you are referring to tympanostomy?) are the primary treatment for chronic ear infections? Doesn't it depend on severity of the symptoms? I understand your reasoning, but for such a complex question a few resources to back up your arguments would be very useful to someone who would try to answer (IMO). Thanks! – Lucky Sep 9 '15 at 12:01

    As for the terminology - it differs across countries, so I just wanted to clarify (that's what the comments are for, after all). It seemed by the way the question was constructed that you already had done some research before posting, so I simply asked you politely to share it with the rest of us :-). The request for prior research is not solely mine, it is a request agreed upon by the community. For more information please refer to the help centre and meta. – Lucky Sep 9 '15 at 17:34

    If most of life took place after nasopharyngectomy, that paper would be relevant. – Susan Sep 11 '15 at 8:13

    It’s not one specific form of the complaint; it’s people who have had their nasopharynx removed, usually as salvage therapy for cancer. The anatomy in the region of the Eustachian tube is....different. Not saying it isn’t interesting, but it does not support your contention that a Google search yielded quick data about this alternative for chronic ear infections that anongoognurse has inappropriately neglected. – Susan Sep 11 '15 at 8:38

    After you clarified the exact nature of your question, I think it has to be closed. For details why I think so, please see meta.health.stackexchange.com/questions/422/…. – rumtscho Sep 11 '15 at 11:25

I think you are having difficulty finding the answer because you are perhaps not asking the right question(s).

...why are more efforts not made to improve their function?

How would you support the assertion that more isn't being done to "improve their function"? The fact that you don't know about something doesn't mean it's not being investigated.

...knowing that the body already has a tube designed to do the same thing without the risks why are more efforts not made to improve [e.g. by stenting] their function?

You will not find any support for your proposal because stenting is not a benign procedure, and the risks of stenting the Eustachian tube far, far outweigh the benefits, as well as the risks of the alternatives. At least tympanostomy tubes have a physiological comparison in ruptured tympanic membranes.

First, the Eustacian tube (ET) is normally closed in people of all ages.

It was Toynbee, in 1853, who concluded from experiments on himself and from the tendency to swallow while descending in a diving bell that the eustachian tube is normally closed and opens only during swallowing.

The ET also opens with yawning. Compare how much time is spent in the resting phase of ET function (all the seconds or minutes spent between swallows and yawns.) This normally non-patent state prevents the migration of bacteria-laden fluids from the posterior pharynx into the sterile middle ear.

Eustachian tube function is a complex affair; it's not easily tampered with. The following details what occurs normally with swallowing (please keep in mind that the pharyngeal end of the ET is above where a bolus of food or saliva passes during swallowing):

Normal ETs had four consistent sequential movements: (1) palatal elevation causing passive, then active, rotation of the medial cartilaginous lamina; (2) lateral excursion of the lateral pharyngeal wall; (3) dilation of the lumen, caused primarily by tensor veli palatini muscle movement beginning distally and inferiorly, then opening proximally and superiorly; and (4) opening of the tubal valve at the isthmus caused by dilator tubae muscle contraction.

A chronically patent ET is pathological (it's called a Patulous ET or PET), and is quite uncomfortable, so much so that ENT's try plugging the tube shut:

Trans-tympanic insertion of a new silicone plug seems to be useful for controlling the distressing symptoms of patients with a chronic patulous Eustachian tube (PET).

It should be obvious that on a purely physiological basis, a stented ET is not a good idea. In addition to migration of bacteria-laden fluids into the middle ear, there is a problem with sound conduction, inappropriate air movement with even minor activities such as whistling, making certain consonant sounds, the difficulty of something as simple as swimming, etc. God help the kid who would start laughing with a mouth full of partially masticated food (have you ever been so caught off guard by something funny while eating or drinking that it comes out the nose?) Imagine the mess that would make if the ET were continuously patent. It's a recipe for disaster.

Add to that the surgical complications, which would be considerably more substantial than with simple (yes, simple) myringotomy tube placement. Finally, those structures allowing ET function are delicate cartilagenous structures, and can easily be damaged by a foreign body (the reason even temporary, dissolvable ET stent use is not recommended). In the 80's, this was done in animal studies. Why you don't find papers of its use in humans is easy to deduce.**

Finally, you are mistaken that there are no attempts to treat (improve) ET dysfunction. There are surgical procedures available for those with severe ETD.

For millions of years, ear infections either resolved on their own, killed the host, or resulted in tympanic membrane (TM, eardrum) perforation. It was very, very common when I was first practicing to look at an adult's TM and see a healed perforation.

Yes, antibiotic resistance developed with overuse of antibiotics. But fewer cases of deafness, mastoiditis, and death from meningitis and brain abscesses occurred as well. We live and we learn.

**Not to mention that mucous can - and did in animal studies in the 80's - block the stent, alone rendering it more harmful than doing nothing at all.

The complications of chronic otitis media: report of 93 cases

  • I’m not looking for support and I didn’t make any proposal. I merely suggested two possible alternative treatments that have been used, but not researched fully. There are others I have found, but figured that listing a couple would imply that there may be many possibilities. I didn’t ask why these possibilities are bad. I asked why we stick with something with known risks rather than looking for something better, when other options are obviously still unexplored. – Dr. Duncan Sep 11 '15 at 6:59
  • If I understand it correctly your answer to why there is not more effort made to enhancing ET function is that the function is complicated, full length stents would be bad, and the solution of ear tubes mimics the worst case scenario solution that the body naturally produces so… (and you didn’t state) so I’ll take the implication that no further attempts to improve ET function should be investigated despite being present? That doesn’t really answer my question. – Dr. Duncan Sep 11 '15 at 6:59

    “Finally, you are mistaken that there are no attempts to treat (improve) ET dysfunction. There are surgical procedures available for those with severe ETD.” I never even implied that there were no attempts to improve ET function, I merely asked why there were not more. Your answer approaches this entire question from a disaster point of view. The surgical procedures are for severe ETD. My question implies a wellness point of view. Improving function early so that it never gets to emergency levels. – Dr. Duncan Sep 11 '15 at 7:00
  • Why you wouldn’t address the idea of balloon inflation is beyond me. It’s an alternate version of a valsalva maneuver with no serious risk that I’m aware of. There’s no surgery, and it is currently used as an effective treatment in some areas. See also, the Otovent. The procedure is supposed to temporarily open the ET and may allow it to drain. I just don’t have enough research on the topic to know the veracity of the idea. Here is the cochrane review from 2013 that came to the same conclusion that I did that there is not enough evidence. bibliotecacochrane.com/pdf/CD006285.pdf – Dr. Duncan Sep 11 '15 at 7:00
  • Another thing that hasn't been researched fully: the efficacy of parachutes in prevention of death by jumping out of airplanes. The worst case scenario of chronic otitis media is death, not TM perforation, which is common and usually very benign. As to balloon inflation, you're correct, it's a common (and old) trick for older kids. (Because you mentioned it with stents , I mistakenly assumed you were speculating about something different.) My apologies for that. Regarding that, ear infections most commonly occur in babies and toddlers who can't blow up a balloon (there goes that idea.) ... – anongoodnurse Sep 11 '15 at 7:08
