Microarray Analysis of Sinus Samples From Patients With and Without Chronic Rhinosinusitis.

Microarray Analysis of Sinus Samples From Patients With and Without Chronic Rhinosinusitis.

The purpose of this study is to compare the bacteria, fungi, and viruses that are present in the sinuses of patients with chronic rhinosinusitis to patients without sinus disease using a new technology, called a microarray, that will allow more accurate identification of microorganisms than current laboratory methods.

Inclusion Criteria:

• Age 18 years or older
• History of chronic rhinosinusitis (CRS)
• Impaired CRS-specific quality of life
• Evidence of sinus disease on a CT scan

Exclusion Criteria:

• Control patients with any evidence of CRS by history, survey, or imaging criteria
