Bioabsorbable steroid-eluting stent Propel® – First experience with thenovel paranasal sinus stent
18 April 2018 (online)
The treatment of chronic frontal sinusitis is often problematic due to the anatomically tight drainage into the nasal cavity. In addition to conservative methods, many surgical therapy procedures have been tested with or without the use of placeholder, but without long-term therapeutic success. In recent years studies have been done to create workable, bioabsorbable paranasal sinus stents. The aim of this work is the clinical testing of general practicability and the short- and long-term therapeutic success of the novel bioabsorbable Propel® stent in chronic frontal sinusitis.
In a prospective case study on 6 patients with chronic frontal sinusitis, the surgical treatment and insertion of the Propel® stent was demonstrated and the stent degradation and long-term success of this therapy were endoscopically controlled and analyzed over a period of 6 months.
The study showed a clinically and endoscopically good biocompatibility with the stent. All patients tolerated the Propel® stents well and there were no local infections or surgical complications.
The results of the case study showed overall good acceptance among the patients without complications as well as a complete, approximately one-month stent degradation. The long-term course also gave satisfactory results over 6 months. Overall, the novel bioabsorbable Propel® stent was therapeutically a useful addition to the conventional sinus surgery, particularly FEES.
