Acute bacterial sinusitis is an infection of the sinus cavities caused by bacteria. It usually is preceded by a cold, allergy attack, or irritation by environmental pollutants. Chronic sinusitis is any case that persists for at least 8 weeks, and is resistant to typical treatments.
Balloon sinuplasty is a short, in-office procedure (typically one hour) to dilate the inflamed passages and flush the infected sinus cavities. Most patients report that nasal breathing improves during the procedure and sinus and head pressure are immediately lessened.
