thanks for writing. How could they miss a ctoma when they did surgery and removed a piece of plastic? what was this piece of plastic from and how did it get there? where at in the ear was this piece of plastic? Does anyone in your family have cholesteatomas? What other symptoms did you have in the ear with it? Did you ever have any fluid build up? Who told you that your retracted eardrum was nothing to worry about was it an ent or general practitioner? What led up to you having mastoid surgery over thirty years ago? How old were you? Do you think that is what caused the ctoma? Did an ent ever look in your ear with a microscope? Was the ctoma visible that way or was it so far back that it couldn't be seen with a microscope? Sorry for all the questions, I just want to understand everything I can and put it together and connect it. Did you ever have a feeling of fullness in the ear? Were you ever told that you have eustachian tube dysfunction? I'm looking for any similarities in our conditions. I hope your surgery was successful. Was it canal wall up or down? Can you get your ears wet?
