How Is Chronic Sinusitis Diagnosed?
Share
Chronic sinusitis is diagnosed through a combination of medical history, physical examination, and sometimes imaging tests. A doctor will ask about symptoms like nasal congestion, facial pain, and loss of smell lasting more than 12 weeks. They may also use a nasal endoscope, a thin tube with a camera, to look inside the sinuses. In some cases, a CT scan is used to get a detailed view of the sinus cavities.
