Wow, a flame war about ear drops..! OK, I'm an ENT doc, so I HAVE to get in on this...
ENT points:
1) People often are inexact when they use the term "equalization". To a non-medical diving audience, this may refer to anything they do to relieve a feeling of fullness in the ear. They may be re-ventilating the middle ear (the space behind the eardrum), or they may be draining the outer ear (the space outside the eardrum), and having similar subjective sensations.
2) Obstruction in the outer ear - from earwax, osteomas ("surfer's ear"), foreign bodies (e.g. earplugs) - can impact on the ability of a diver to clear the middle ear space. True equalization generally relies on the eardrum moving outwards, since the other walls of the middle ear are unyielding bone. This is usually associated with the opening of the Eustachian tube (the natural drainage pathway of the ear). SO, if there is something that is blocking the eardrum from moving, theoretically this could make equalization more difficult. One could imagine a situation where a partially blocked outer ear combines with water to cause this problem - to be relieved when the water drains out (maybe with eardrops). Not a very common scenario, but I think that BKP's statement that the eardrops help him equalize could have scientific basis in this way. Of course, point 1 still applies, and it doesn't take much movement of the drum to allow for ventilation...
3) Nasal steroids (e.g. Flonase) are good for for nasal obstruction due to allergies or other types of congestion, but have not been shown to affect the function of the Eustachian tube. In fact, in children, even decongestants like Afrin and Sudafed have not been shown to be helpful for middle ear fluid (OME): Practice Guidelines - June 15, 2004 - American Family Physician
4) Since there isn't a lot of literature on this in adults, and since I don't get to dive very often, if my ear locks up on a dive trip, I take decongestants and steroids (no WAY I'm missing a precious dive unless it's absolutely necessary!). Steroids are controversial and have side effects, so I'm reluctant to prescribe them for others.
5) Doctors make TERRIBLE patients.
Now a Web forum point:
Despite the fact that I think that BKP may be right on one level, he has written a few troubling phrases which seem to have caused some bad feelings:
"Look Bill. Frankly, I don't know what your problem is"
"Now I *do* see what your problem is, Bill... You need need to get a life."
"Happy? If not, feel free to write another novelette. "
And while Bill has also responded at one point in a somewhat confrontational manner, I think that BKP has him beat here... even given Bill's "novellette"...
SO, I hope that you all won't turn on me for getting in the middle of this. I really like ScubaBoard, and you both clearly care a lot about diving and helping other people (that's why we post here, right?)...
Bonaire... here I come!
