Acute rhinosinusitis (ARS) involves inflammation of the nasal cavities and sinuses, lasting less than four weeks. Most cases are caused by viral infections, which means they typically resolve on their own. However, a small percentage may involve bacterial infections requiring different treatments.
When Viruses Attack
Acute viral rhinosinusitis (AVRS) often resolves within 10 days with supportive care. This includes using over-the-counter pain relievers and saline irrigation to relieve symptoms. If symptoms persist beyond 10 days, it may be a sign of a bacterial infection.
The Bacterial Battle
Acute bacterial rhinosinusitis (ABRS) can sometimes resolve without antibiotics but may require treatment if symptoms worsen. Antibiotics can help shorten the illness but come with their own side effects, so careful consideration is needed.
