Mastoid Air Cell Fluid and Tinnitus; Need an Opinion.

hello again,

i seem to live on this site.

just wanting an opinion.

Head CT/MRI have demonstrated fluid in the right mastoid air cells post a really nasty external ear infection last year.

ENT have flippantly said that may be the cause of my t, and may go away once the fluid is absorbed. He refused to repeat the CT.

Has anyone experienced this? I had some disagreement with my treating doctors re my diagnosis last year (external ear infection VS mastoiditis). I have sought another opinion and still no joy.

Does this explanation sound plausible???
