Plain Language Summary: Adult Sinusitis Update.

Abstract

This plain language summary is an overview of sinusitis (pronounced sign-you-side-iss). The purpose of this plain language summary is to provide patients with standard language explaining their condition in an easy-to-read format. This summary applies to those 18 years of age or older with sinusitis. The summary is written in an FAQ (frequently asked questions) format. The summary addresses how to manage and treat sinusitis symptoms. A healthcare provider may refer to a sinus infection as sinusitis or rhinosinusitis (pronounced rhi-no-sign-you-site-iss). This includes the nose as well as the sinuses in the name. The summary is based on the published 2025 "Clinical Practice Guideline: Adult Sinusitis Update." The evidence-based guideline includes research to support more effective diagnosis and treatment of adult sinusitis. The guideline was developed as a quality improvement opportunity for managing sinus infections by creating clear recommendations to use in medical practice.
