Anatomy of the sinuses Ethmoid and maxillary sinuses are formed in utero and are present at birth. Frontal sinuses are not present until age 5-6 years. [meddean.luc.edu]

The predictive value of these signs and symptoms was 81% with 4 predictors present, and it was 92% with all 5 predictors present [16]. However, radiographic studies in general cannot distinguish between viral and bacterial causes of sinusitis. [academic.oup.com]

Patients should be advised of the need to re-present if any red flag symptoms should arise (Box 2). Box 2. [racgp.org.au]

See Workup for more detail. Management Treatment of acute sinusitis consists of providing adequate drainage of the involved sinus and appropriate systemic treatment of the likely bacterial pathogens. [emedicine.medscape.com]

A thorough diagnostic workup should be performed to rule out any underlying conditions, including allergies, asthma, immune system problems, gastroesophageal reflux disorder, and structural problems in the nasal passages. [mountsinai.org]
