Summary

This comprehensive lecture by Professor Zach Murphy covers rhinosinusitis, defining it as inflammation of the nasal cavity and paranasal sinuses. It distinguishes acute (<4 weeks) from chronic (>12 weeks) forms. Acute viral rhinosinusitis is most common, caused by viruses like rhinovirus, leading to mucosal inflammation, ciliary stasis, and obstruction of sinus drainage. Acute bacterial rhinosinusitis is suspected with persistent symptoms, severe onset, or double worsening. Acute invasive fungal rhinosinusitis is rare but dangerous, especially in immunocompromised patients. Chronic rhinosinusitis is classified by presence or absence of nasal polyps, with different inflammatory profiles. Complications include orbital cellulitis, cavernous sinus thrombosis, and intracranial infections. The diagnostic approach emphasizes clinical criteria, with imaging reserved for complicated cases. Treatment involves supportive care, antibiotics for bacterial cases, and surgery for chronic or complicated disease.
