Bioabsorbable steroid-releasing implants in the frontal sinus ostia: a pooled analysis

Area of Science:

• Otolaryngology
• Rhinology
• Surgical Innovation

Background:

• Chronic rhinosinusitis (CRS) poses challenges in frontal sinus surgery.
• Mometasone furoate implants offer a potential solution for improving postsurgical outcomes.

Purpose of the Study:

• To evaluate the efficacy of bioabsorbable steroid-releasing implants in frontal sinus ostia (FSO) for CRS patients.
• To assess implant performance across various patient subgroups using pooled data from two randomized controlled trials (RCTs).

Main Methods:

• Pooled data from 160 subjects in two RCTs were analyzed.
• Subjects received an implant in one FSO, with the contralateral side serving as control.
• Subgroup analyses were performed on data collected up to day 90.

Main Results:

• Steroid-releasing implants significantly reduced the need for postoperative interventions, surgical interventions, and oral steroid use by day 30.
• By day 90, implants led to significant reductions in postoperative interventions, restenosis/occlusion rates, and inflammation, with increased FSO diameter.
• Improvements in restenosis/occlusion and FSO diameter were observed across all analyzed subgroups.

Conclusions:

• Bioabsorbable steroid-releasing implants enhance frontal sinus surgery outcomes up to 90 days.
• Implant efficacy is consistent regardless of patient-specific factors like asthma, prior surgery, or disease severity.
• These implants represent a valuable tool for managing CRS patients undergoing frontal sinus surgery.
