Which condition involves inflammation of the sinuses?

• A. Emphysema
• B. Sinusitis
• C. URI
• D. TB

Answer: (B)

Inflammation of the sinuses is sinusitis. The sinuses are air-filled spaces around the nasal passages, and when they become inflamed, drainage is blocked, leading to facial pressure or pain, nasal congestion, thick nasal discharge, and sometimes fever or reduced sense of smell. It can be acute or chronic and may follow a cold or result from allergies. Treatment focuses on relieving drainage and inflammation, with nasal saline irrigation and decongestants, and antibiotics if a bacterial infection is suspected or persistent. The other conditions involve different areas: emphysema affects lung tissue, a URI targets the upper airway in general, and tuberculosis is a lung-centered infection not defined by sinus inflammation.
