The diagnosis of sinusitis.

The diagnosis of sinusitis is usually based on evidence obtained from history taking and physical examination. The making of the diagnosis has been made easier recently by CT scanning and by the availability of the rigid Hopkins endoscopes. However, the diagnosis remains basically a clinical one. Radiologic and bacteriologic evidence may also help, but should be considered neither necessary nor required. Minor radiologic abnormalities are not infrequently seen in normal asymptomatic people and require no medical or surgical attention. Fungal sinusitis is on the increase. Sinusitis in children is briefly reviewed.
