How do I know if I have Cholesteatoma?

You wouldn't know going into it that that is what you have but after living through it once you definitely know if it has come back.

Continious ear infections, wich not treated by antibiotics, you should go to an otologist

You probably cannot be certain w/o a CT (or back in 1998 it was the surgical procedure when mine was discovered!). I think CT scans have vastly improved. If you have thick, granular, possibly grey or bizarre colored gunk coming from your ear, that might be a good indication. If you have severe ear pain that feels like your ear IS about to burst, that may be an indicator. If you've had these and you go undiagnosed (bad doctor or you've not seen any doctor), eventually you'll probably get pain in the mastoid bone (behind ear) and a very disturbing CLOGGED ear/face....if it proceeds untreated you may find your facial nerve affected. It would feel like your foot does when it falls asleep. Headaches that come on after one or several of the symptoms I described. Headaches that interrupt your thinking process....I had those too. One sided, the C-toma side (ONLY). ALL symptoms were ONLY one-sided.

If you feel dizzy, got pain you‘ll go to the doctor and they will find out

Though may exhibit the symptoms associated with the disease however only a trained physician can make the diagnosis many general practitioners are not aware of the condition

General feeling of poor hearing in one or both ears, discharge, foul smelling.

You need to see an ENT and get a catscan

I know when my cholesteatoma is back when my symptoms start coming back. I follow up with my ENT who confirms it.

you will have pain in the back of your ear your ear with ache and it's more than likely that you have a history on common ear infections
