Question for you pros...
Otitis media causing mastoiditis vs malignant otitis externa - how do you differentiate the two?
My understanding is that OE that causes destruction of soft tissue into surround areas including mastoid air cells is Malignant OE by definition. Now, OM that extends into the mastoid air cells is Mastoiditis by definition.
The reason why I think it's key to differentiate between the two is that MOE is more aggressive than Mastoiditis and the treatment for each is different. MOE needs IV abx for 6 weeks while Mastoiditis (w/o periosteal abscess) can be treated w/ po abx.
I had a patient last week who presented w/ an exam consistent w/ OE and we got a CT temporal bone - it showed opacification of the mastoid air cells with some degeneration.
I had a discussion with the other senior resident and it was decided that the patient had OE and OM causing mild mastoiditis. The ENT resident also concurred.
I don't get it..... I thought that if you have OE and mastoid involvement - that was MOE by definition?
Is there something I'm missing? Do you need destruction of the surround temporal bone around the external canal + mastoid air cells to call it MOE?
