Steroid-Eluting Stents provide Breakthrough Treatment for Eosinophilic Chronic Rhinosinusitis


Clinical trial finds steroid-eluting stents a promising treatment for Eosinophilic Chronic Rhinosinusitis

Eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP) is a difficult condition that causes a lot of symptoms and tends to come back even after treatment. However, a clinical trial has found a potential solution that shows promise in managing ECRSwNP: steroid-eluting stents. A clinical trial studied the effectiveness and safety of these stents in treating ECRSwNP.

The Clinical Trial

In the trial, researchers enrolled 98 patients aged 18 to 65 who had ECRSwNP and needed surgery. At the end of the surgery, they randomly placed absorbable steroid-eluting stents in one sinus of each patient. The researchers wanted to see how well the stents worked, so they measured different things like nasal symptoms, nasal resistance, and eosinophil counts in the ethmoid mucosa.

Results and Findings

Ninety-five patients completed the trial, and the results provided important insights into the effectiveness of steroid-eluting stents. The researchers found that the stents led to significant improvements in various aspects of the condition.

 They saw that the patients who had the stent had lower scores on the Lund-Kennedy endoscopic scale at 4, 8, and 12 weeks after the surgery. This means that their sinuses were in better condition compared to the patients who did not have the stent. The control side (without the stent) showed more tissue inflammation at week 4 and higher scores for volumetric measurements, nasal obstruction, and overall nasal symptoms at week 8. These results suggest that the stents can help reduce inflammation and improve symptoms.

Safety and Side Effects

It is important to make sure any treatment is safe for patients. The good news is that the stents used in the trial were well-tolerated, and no serious side effects were observed. This means that patients did not experience any major problems or harm from the stents.


The findings of this study have important implications for the treatment of ECRSwNP. Steroid-eluting stents have been shown to effectively reduce inflammation and improve symptoms after sinus surgery. Even after the stents dissolved, the benefits of the treatment continued. This makes the stents a valuable option for patients with ECRSwNP who have had surgery.

However, it is important to remember that more research is needed to fully understand the long-term effects and benefits of these stents. It is also essential for patients to consult with their healthcare providers before considering this treatment option. Doctors can provide personalized advice based on a patient's specific condition and overall health.


Steroid-eluting stents have the potential to be a breakthrough in the treatment of ECRSwNP. These stents can help reduce inflammation, improve symptoms, and provide lasting effects. This brings hope to individuals struggling with this challenging condition. Continued research will help us better understand and refine the use of steroid-eluting stents, leading to improved treatments for ECRSwNP patients.
