Introduction “Nasal stents are a critical innovation in sinus surgery, helping patients recover from chronic sinusitis and other related conditions. Today, we’ll explore how these devices work, their materials, and the latest advancements in drug-eluting stents.” Part 1: Importance of Nasal Stents “After sinus surgery, the healing process can be tricky. The nasal cavity is prone to narrowing or closing, known as stenosis, which can lead to complications. That’s where nasal stents come in. They help keep the sinus cavity open, allowing proper airflow and drainage, reducing the risk of re-blockage.” Part 2: Materials and Design “Nasal stents are made from various materials like rubber, gold, Silastic, and Dacron. These materials are flexible and durable, designed to conform to the sinus cavity’s shape. Some stents are expandable at one end to prevent extrusion, ensuring they stay in place as the sinus heals.” Part 3: Drug-Eluting Stents – The Propel Stent “An exciting advancement is the drug-eluting stent, such as the FDA-approved Propel stent. This stent not only holds the sinus cavity open but also slowly releases a corticosteroid, mometasone furoate, over 30 days. The steroid reduces inflammation and scarring, promoting a smoother recovery. What’s more, the Propel stent dissolves on its own, eliminating the need for removal.” Conclusion “Studies have shown that nasal stents, especially drug-eluting ones like Propel, are highly effective in helping patients recover from sinus surgery. With their ability to maintain open airways and deliver medication directly to the sinuses, they represent a huge leap forward in sinus treatment.”
