Diagnosis of rhinosinusitis usually is based on clinical history, physical examination and endoscopic examination of your nose. We may also obtain a CAT scan of your sinuses or endoscopically obtain a sample from your sinuses to test for bacteria or fungus.

We have a CAT scanner in the clinic, as well as state-of-the-art endoscopy equipment to make a definitive diagnosis on your first visit.

Allergy testing for both ingestants and inhalants can help helpful in determining the cause of rhinosinusitis.
