Sinus surgery is commonly used for the treatment of individuals with chronic rhinosinusitis, infection and polyposis. FESS are intended to open closed sinus ostia to allow proper drainage and air flow and prevent recurrent sinus infections. Inflammation, polyp recurrence, stenosis of the surgically enlarged sinus ostia, adhesions and middle turbinate lateralization (adhesion of the middle turbinate to the lateral nasal wall) represent suboptimal outcomes following sinus surgery and lead to increased rates of revision. Middle turbinate lateralization may cause obstruction of the middle meatus and result in recurrent infection of the maxillary, ethmoid, or frontal sinuses (Otto, 2010). Several devices have been proposed that are designed to help maintain sinus ostial patency by reducing scarring and synechiae formation following FESS. These include stents, packing, sponges, and gels.

One such device is the Propel™ sinus implant. This device is a bioabsorbable drug eluting stent that is implanted into the sinus ostia following FESS and is designed to release the corticosteroid mometasone furoate over a period of several weeks as the stent itself is slowly resorbed. It is proposed that this stent has the potential to improve surgical results by stabilizing the middle turbinate, preventing obstruction by adhesions and reducing edema. It is designed to deliver corticosteroid to the surgical cavity with minimal potential for drug-related complications known to occur with systemic steroids and lessen the need for revision surgery to lyse adhesions. At this time, there are three peer-reviewed published clinical trials addressing the use of this device. These papers describe the three trials presented to the FDA during the pre-market approval (PMA) process. These studies are known as the ADVANCE, CONSENSUS II and the ADVANCE II trials. The latter two are randomized intra-patient controlled trials, while the ADVANCE trial was a case series.

[ANTROSTOMY] Operative Technique

Surgery begins with a careful examination of the nose. Key landmarks are the three turbinates or chonchae (conchae = shell) arising from the lateral nasal wall, and the osteomeatal complex. The most anterior, or nearest to the front, structure within the osteomeatal complex is the uncinate process. This semilunar ridge of bone projects in front of the ostium of the maxillary sinus. Behind or posterior to the uncinate process, is a group of ethmoid cells known as the bulla ethmoidalis. The uncinate process must be completely and atraumatically removed to visualize the entire ethmoid sinus and maxillary ostium. In our experience, incomplete removal of the uncinate process is a significant factor in leading to revision surgery.
