By definition, “chronic” rhinosinusitis is inflammation of the sinuses that lasts 12 weeks or more. It can be accompanied by a swelled feeling in the face, fatigue, headache and loss of taste, to name a few. (Just thinking about it makes my head hurt.) Of the 30 million people in the United States who suffer from CRS, about a half-million elect to correct it through surgery.
Often, however, even with surgery, the symptoms return.
But Earnhardt thinks her company, Palo Alto’s Intersect ENT Inc., has a better answer. Its Propel stent is placed in the sinus cavities right after sinus surgery, keeping the sinuses open and releasing a corticosteroid over a period of time.
Then Propel disappears — it is absorbed into the body.
