Abstract
The severity of acute rhinosinusitis of 132 children was classified according to the Japan Rhinologic Society's Clinical Practice Guidelines for Acute Rhinosinusitis (2010 edition), and maxillary sinus ultrasonography was performed. Many cases in all severity classifications were negative on ultrasonography, and these cases often recovered within a week. Even when the severity of symptoms and nasal examination were the same, the cases classified as severe on ultrasonography diagnosis tended to require longer treatment. In addition, cases that were negative on ultrasonography at the time of diagnosis but subsequently began to test positive also required long treatment. This suggests that a more accurate diagnosis of rhinosinusitis can be made by performing imaging in addition to symptoms and nasal examination. Ultrasonography, which is minimally invasive and can be repeated, is therefore thought to be useful in the diagnosis in pediatric rhinosinusitis.
