Corticosteroid-eluting bioabsorbable stent or spacer insertion during endoscopic sinus surgery to treat chronic rhinosinusitis

The procedure

In this procedure, a stent (short tube) is inserted through the nose using an endoscope (a thin tube with a camera on the end) and placed in the drainage system of a sinus. The stent holds the drainage system open, and slowly releases corticosteroid medication into the sinus. The aim is to reduce inflammation. The stent dissolves over time. The procedure is usually done using a general anaesthetic during sinus surgery.
