Subject: Otitis Externa (spinoff from "great new gear for 99")
I've had a lot of problems with recurrent otitis externa. I've asked around 
and found it's actually epidemic in technical diving. No surprise really, 
since we spend a lot of time under water -- the water leaves our ear canals 
washed-out and vulnerable to infections However, nobody talks about this 
unless you ask directly. A cave divers from Sweden, R. Lundgren, told me 
that freshwater is actually worse than seawater in this respect. Needless 
to say, polluted water of either category tops the list of "interesting" 
micro-organisms. I'd like to know what those who log hours underwater 
around the world do to avoid/limit external ear infections. Keeping the 
external ear canals dry is a very good idea, yet hard to accomplish without 
wearing a hard hat.

My advice would go along the lines of :
1) Keep ears dry (medical advice we may not be able to comply with)
2) Dry out your ears as soon as possible after surfacing
3) Use ear drops prophylacticly after a dive (diluted vinegar may work)
4) Whatever you do, no Q tips! Picking your itching ears breaks the 
external ear lining and leaves the ears more vulnerable to infection

WKPP or others spending long hours underwater -- how do you fight external 
ear infections?

regards,

Hans
