Fungal sinusitis is included in the general

0:05

categorization of rhinosinusitis, and I mentioned

0:08

previously that you may see on the request

0:10

slip CRS, which is chronic rhinosinusitis.

0:15

And that's usually where the patients

0:16

are being evaluated for potential

0:18

functional endoscopic sinus surgery.

0:21

Acute rhinosinusitis is generally

0:23

treated empirically with supportive care,

0:27

sometimes with antibiotics when there's a

0:30

presumption of bacterial infection as opposed to

0:34

viral infection, which accounts

0:35

for most of the rhinosinusitis.

0:37

So within the rhinosinusitis classification,

0:40

we have acute presumed bacterial rhinosinusitis.

0:44

Then we have our chronic rhinosinusitis without

0:47

polyps, which accounts for 60% to 65% of those

0:51

chronic rhinosinusitis.

0:53

This is a sinusitis that lasts 12 weeks or more,

0:56

and it may have two out of the four: that is, drainage

0:59

from the nose, obstruction, facial discomfort, maybe

1:02

hyposmia, with a positive CT scan or endoscopy.

1:06

Chronic rhinosinusitis with polyps accounts

1:09

for 20% to 33% of the chronic rhinosinusitis,

1:13

and these are patients who may have

1:15

aspirin sensitivity, asthma, some atopic

1:20

characterization that leads to the presence

1:24

of the polyps and an allergic reaction.

1:26

And then within that category, we also have the

1:30

classic allergic fungal rhinosinusitis, which I

1:33

showed you examples of. That accounts for a small

1:36

part of the chronic rhinosinusitis categorization.

1:40

And remember, these have the

1:41

eosinophilic mucin and hyphae.
