What is Chronic Sinusitis?

Chronic sinusitis is a persistent inflammation of the sinus cavities lasting 12 weeks or longer, often caused by infection, nasal polyps, or structural blockages. Symptoms include nasal congestion, facial pain, reduced sense of smell, and thick nasal discharge. It affects approximately 12% of adults globally and can significantly impact quality of life. When medical therapy fails, surgical options like functional endoscopic sinus surgery (FESS) or balloon sinuplasty may be recommended to restore sinus drainage.
