Topical therapies for management of chronic rhinosinusitis: steroid implants

Chronic rhinosinusitis (CRS) causes severe symptoms that lead to poor quality of life. When optimal medical therapy does not improve CRS symptoms, then endoscopic sinus surgery (ESS) can be used in patients with persistent symptoms and radiographic evidence of CRS to improve patients’ symptoms and quality of life. Despite appropriate and complete sinus surgery, there can be issues after sinus surgery such as synechiae formation and recurrence of polyps in certain CRS patients that can decrease long‐term outcomes. Corticosteroids are used to decrease postoperative scarring and edema as well as prevent recurrence of nasal polyp formation after sinus surgery. However, the use of oral or systemic steroid can lead to serious short‐term and long‐term complications. Therefore, a safer alternative would be the topical delivery of steroid via steroid‐eluting sinus implants.
