I had tubes in my ears as a child, I have heard this could affect clearing your ears because of scarring. My parents said that the tubes came and went normaly and I only needed one round of them. I have no problems clearing on airplanes before but I was curious if it was same as diving.
Thanks
As someone whose entire life seems to revolve around putting in tubes, you might expect that I would downplay this "scarring" issue just because ear tubes paid for my dry suit! However, I assure you, that I am speaking from the heart here, and want nothing but the best for my fellow divers....
Ear tubes are placed to temporarily compensate for an immature Eustachian tube, which is extremely common in childhood. Most children outgrow this problem by age 5 or so, and while some children may require multiple sets of tubes, the vast majority of them improve with age, and the eardrum heals uneventfully.
Eardrum scarring is a commonly misunderstood phenomenon. The real complication of tubes is persistent perforation, where the tube hole fails to close. This is very uncommon, but a hole in the eardrum would certainly be something that would cause a problem with diving.
However, what most people mean by scarring is that it is sometimes possible to see where the tube was placed previously. In most cases, this is simply a cosmetic issue, and does not cause any functional problems.
Another condition which is often confused with ear tube related scarring is tympanosclerosis, where plaques of calcium deposit in the eardrum. While it is not clear exactly what causes this, it seems to be related more to the eardrum blood supply, and can happen without any history of tubes. Conversely, children who have had many sets of tubes often do not have this at all. In any case, this is another cosmetic issue for the most part, since it does not seem to cause any hearing loss or be a sign of Eustachian tube problems.
So the bottom line is if a diver's eardrums have healed closed from the tubes that were placed as a child (almost always the case) and if the diver can equalize easily (again, virtually all childhood Eustachian tube dysfunction resolves by the teenage years), a history of ear tubes is not a reason to avoid diving...
