Acute sinusitis is a common clinical problem in general practice. Approximately 0.5% to 2% of all episodes of the common cold develop into a purulent sinusitis; and in European general practice, 1% to 2% of all patient visits to physicians are for suspected acute sinusitis.1 In the United States, there is a clear discrepancy between the patient's perception and the physician's diagnosis. “I have a sinus problem” is one of the most common reasons for clinical encounters in the United States and accounts for 25 million office visits per year.2
