Key Points about Acute Bacterial Sinusitis

• Definition: Acute bacterial sinusitis is an infection of the paranasal sinuses lasting less than 12 weeks and is typically caused by bacterial pathogens, following a viral upper respiratory infection.
• Causes: Common bacterial pathogens include Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Risk factors include previous viral infections, nasal obstruction, and allergic rhinitis.
• Symptoms: Key symptoms include nasal congestion, purulent nasal discharge, facial pain or pressure, and reduced sense of smell. Symptoms persisting for more than 10 days or worsening after an initial improvement suggest bacterial involvement.
• Investigations: Diagnosis is usually clinical, based on symptoms and history. Imaging, such as CT, is reserved for complicated or chronic cases. Nasal swabs for culture are not routinely recommended unless complications are suspected.
• Management: Most cases resolve without antibiotics, but those with severe or persistent symptoms may benefit from antibiotics such as amoxicillin or co-amoxiclav. Supportive care includes nasal saline irrigation, analgesics, and decongestants.
• Complications: Complications, though rare, can include orbital cellulitis, meningitis, and intracranial abscesses, requiring urgent intervention.
