 Definition of "sinus infection"

I sent this before but I didn't get any good answers so I am sending
it again.  (One person said to look on his web page but I didn't find
the answers to ANY of my questions there.)

What is the definition "sinus infection"?  I know it is an infection
in the sinuses but what exactly constitutes an "infection" when it is
in the nasal sinuses?  

Obviously if there are NO bacteria at all in the sinuses there is no
infection and if the sinus is completely filled with bacteria it must
be an infection but what about conditions in between those extremes?
Does the opening to the sinus have to be completely blocked and the
sinus completely filled with fluid 100% of the time to be considered a
sinus infection?  

Is it possible to have a sinus infection that doesn't show up on an
x-ray? Is it possible to have a sinus infection that doesn't show up
on a CAT scan?  What is the best way to detect a sinus infection?  Is
it possible to have a sinus infection that Doctors can't detect?

If it is not too much trouble, please send e-mail as well as
answering in the newsgroup.  My news feed is not always that
reliable (I often see replies to messages I never see).  I am
sometimes too ill to check my newsgroups for several days and my
BBS/ISP never keeps more than 3-4 days worth of messages and
sometimes keeps less than one days worth.  Thank you in advance for
all replies.

     I'm not sure what your question is here.  Sinusitis is an infection of
one or more of the paranasal sinuses.  When the normally sterile paranasal
sinuses are disrupted by a microorganism, this denotes infection.  This is
recognized by the recovery of an organism from the sinus cavity.

     No,  it is a little more complicated than that.  Usually acute
sinusitis results in inflammation of the sinus mucosal lining.  In chronic
sinusitis the prolonged exposure to noxious microorganisms leads to an
irreversible change, whereby the sinus cavity is replaced with cells that
don't allow sterility anymore.

     A physician who is qualified (otolaryngologist, ENT) can diagnose
sinusitis properly if they take the time to exhaust all measures.  As far as
infections not showing up on plain x-ray or CT, it is doubtful in my opinion
that something wouldn't show up on a CT scan of the sinuses.  The difficulty
is determining whether an abnormality, such as inflammation is caused by
bacterial, viral, or other nonbacterial pathogenesis.  Having a comorbid
condition (e.g., colds, influenza) can also complicate the diagnosis.  The
presence of bacterial infection can only be determined by culture of the
sinus cavity.  This is done by direct puncture and aspiration.  Sinus
puncture is usually indicated when the patient is nonrespondent to
antimicrobial treatments, or have circumstances that necessitate this
procedure.

Hope this helped a little,

Dear Daniel

(Excuse my poor English)

I'm afraid that I can not answer your questions regarding the
definition of sinusitus, but if I may take a guess, it appears as
though you are having sinus related problems. May I thus
draw your attention to my own sinus related problem which
I believed to be sinusitus for years, but turned out to be a
swelling of nasal tissue due to an extreme level of allergy.
My nose feels blocked, but is not, and a pressure pain is
more or less conitinuesly my tormentor. For the many years
during which I believed to have sinusitus I used sinusitus
medication, which helped because of the painstillers and
thus reinforced my believe of having sinusitus. To sum up:
if you don't have the more classic symptoms ie runny nose/
dark-moldy nasal excretions then you may have the same
problem as me. My medication includes a daily intake of
antihistamine (pills) and stereoidal nasal spray.

It could be both, an allergy and a sinusinfection. Etienne, what spray do
you use? I use rhinocort, but i'm not very satisfied..
bye, marieke
