FRONTAL SINUS STENTS
Dr. Bradley J. Chastant has been successfully using traditional sinus stents for more than 10 years and Propel medicated stents for the past 3 years. The first Propel medicated stent procedure that he performed on February, 29, 2012 at Lafayette General Surgical Hospital, was a first in the state of Louisiana. Dr. Chastant, a professor with LSU department of Otolaryngology, is board-certified in both Otolaryngology and in Facial Plastic Surgery. In addition to non-medicated sinus stents, he is the only doctor in the region now using medicated frontal sinus stents to help prevent recurring blockage following surgery. This has significantly changed the health of his patients suffering from sinusitis.
WHAT ARE FRONTAL SINUS STENTS?
There are two types of frontal sinus stents currently available; medicated and non-medicated. In general, frontal sinus stents are used after endoscopic sinus surgery to avoid restenosis (narrowing of a blood vessel). Stents help maintain drainage of the frontal sinuses and provide ventilation.
Medicated sinus stents, such as PROPEL™ allow for anti-inflammatory medications to be delivered to the sinus tissue as well as provide drainage and ventilation. PROPEL™ has been clinically proven to prevent obstruction of the frontal and ethmoid sinuses following surgery, resulting in improved post-operative outcomes and reducing the need for additional surgical procedures.
WHEN IS A FRONTAL SINUS STENT NECESSARY?
Sinus stents are necessary any time the frontal sinus outflow tract must be kept open or unobstructed following sinus surgery to promote drainage and allow for proper healing. Dr. Freeman recommends the use of the Freeman Frontal Stent in the following conditions:
- Blockage of the frontal outflow tract as a result of previous surgery or trauma opened either endscopically or through an external skin incision.
- Chronic frontal sinusitis drained endoscopically
- Frontal sinus mucocele (cyst) decompressed endoscopically or through a Lynch incision
- Polyps or hypertrophic mucosal disease (excessive thickening of the mucosal tissue) in frontal recess removed endoscopically.
HOW CAN FRONTAL SINUS STENTS HELP WITH SINUS SURGERY?
Frontal sinus stents reduce the need for procedures such as frontal sinus obliteration (where the sinuses are completely removed to prevent chronic infection making them non-functional) and front sinus drill out procedures (which allows the sinuses to be flushed by drilling through bone and inserting a catheter into the sinuses). Long-term use of frontal sinus stents may also reduce the rate of recurrent sinusitis and reduce the need for antibiotic therapy, since the stents will help to maintain long-term patency of the front sinus outflow tract, which is usually challenged by scar formation and stenosis following surgery.
