The same word came up a few months ago with a student of mine!
The easiest solution is not to use that word at all! I know no one in the U.S. that attempts it -- except for medical students, perhaps! Americans simply say "an ear-nose-throat doctor", or even more simply, "an ENT specialist".
I hate a word I've first encountered in studying poetry. I can hardly pronounce it (though many people say I speak nearly like a native). Even now I can't remember it. See I makes my blood boil
I remember that when I started learning English I couldn't pronounce "understand". I always ended up saying "Amsterdam" (I think I learnt both words at the same time, I was about eight and we were learning the European capitals at school). Older people laughed their heads off each time I said it. We didn't start learning English at school until a few years later, and then was my turn to laugh
