Clinical practice guidelines for the management of chronic sinusitis in children.

Chronic sinusitis in children is a common and vexing disease for clinicians and the public. There are insufficient data in the literature to develop an evidence-based clinical guideline. Experience in managing pediatric chronic sinusitis has been gained through a multidisciplinary clinic at our institution during the past 3 years. A panel of experts was formed, and with the guidance of a guideline methodologist, the development of a rigorous outcome-based guideline was undertaken. Symptom-improvement and recurrence estimates for a variety of medical and surgical treatments were assessed. Wide probability estimates were made by the panelists in most cases. Although we refrained from making specific recommendations, we developed a ranked series of practical treatment options taking into account side effects and costs.
