A Prospective, Randomized, Multi-Center Evaluation of MediENT® Middle Turbinate Implant Versus MeroPack®, a Bioresorbable Nasal Dressing / Sinus Stent After Endoscopic Sinus Surgery

Not Applicable

Completed

• Conditions: Synechia

• Registration Number: NCT01733667
• Lead Sponsor: ENTrigue Surgical, Inc.

Brief Summary

The purpose of this study is to compare the safety and effectiveness of MediENT to MeroPack after FESS.

Detailed Description

MediENT is designed to minimize lateralization of the middle turbinate, which can cause scarring and obstruction of key sinus openings after endoscopic sinus surgery.
