How long is sinus surgery intended to last?

June 02nd, 2017

Sinus surgery can be very helpful in opening up the airway so you can breathe properly. It can reduce symptoms like recurring infections with cough and hoarseness, and others. But sometimes, the benefits can fade after a while.

In fact, according to one study, just one year after endoscopic sinus surgery, 9% of patients were scheduled for a repeat procedure (this study involved 237 patients); 16% of the patients in the study said their symptoms had not changed, and 1% said they had gotten worse. Fewer than half said their symptoms had gone away entirely.[1]

Over time, more of the patients in this study will probably have to go back into the operating room because their sinuses will have gradually closed back up. This is backed up by a different study, in which 23 out of 91 patients had revision surgery within four years because their symptoms had come back.[2]

Here is why. In sinus surgery, the surgeon removes polyps and other swollen or inflamed tissue that blocks the sinus passages. This allows air to pass freely through the sinuses once the surgery site has healed. But over time, the diseased tissue can grow back. Within two to five years, some patients’ symptoms also come back, and some of them may require more surgery to get their sinuses back into good working order.

That’s the evidence shown by two studies in established medical journals. We can conclude that, as time goes by, it is more and more likely that symptoms will come back and a few patients will need revision. Still, in the four-year study, only about 25% of studied patients had symptoms bad enough to require surgery again.[2] The odds vary depending on your individual condition, your sinus anatomy, how well you respond to nonsurgical follow-up treatment, and other factors.

New technological advancements are aimed at improving the outcomes of surgery and offer longer periods of lasting relief. Some ENT physicians offer PROPEL sinus stent with surgery. PROPEL is an implantable sinus stent coated with an anti-inflammatory medicine. During sinus surgery, the surgeon clears the diseased tissue and places PROPEL inside the sinuses. The spring-like design allows it to conform to the unique shape of the sinus, securely prop the sinuses open, and deliver medicine directly to the diseased tissue.

PROPEL sinus stent helps improve the results of sinus surgery by decreasing the chance of post-surgical scarring and inflammation and reducing the need for oral steroids. After about 30 to 45 days, it dissolves. PROPEL is clinically proven to maintain the outcomes of surgery. This means less likelihood for additional surgical interventions or the need for oral steroids.[3]

So if the question is how long sinus surgery can last, the answer is: usually, at least a few years, but it depends. PROPEL can help maintain the outcome of surgery. Talk with your doctor if you are having chronic sinus symptoms. Your doctor and you may be able to figure out the underlying issue, determine whether surgery is appropriate, if PROPEL can help, and how likely it is that you’ll respond positively.

Why find an ENT physician ?

If you suffer from chronic sinus infections, you may need to see an ENT physician, who is also called an ear, nose, and throat doctor or an otolaryngologist. These specialized physicians are experts in both the medical and surgical management of chronic sinusitis.

Intersect ENT makes information about physicians and facilities that offer PROPEL® sinus stents available. Physicians and facilities are listed based upon proximity to the zip code you have entered.

Safety Information

The purpose of the site is to help create awareness about sinusitis and treatment options for the disease. Please note that information contained on this site is not medical advice. It should not be used as a substitute for speaking with your physician. Always talk with your physician about diagnosis and treatment information.

The PROPEL sinus implants are intended for use after sinus surgery to maintain patency and to locally deliver steroids to the sinus mucosa: PROPEL for use in the ethmoid sinus, PROPEL Mini for use in the ethmoid sinus and frontal sinus opening, and PROPEL Contour for use in the frontal and maxillary sinus ostia. The implants are intended for use in patients ≥18 years of age. Contraindications include patients with intolerance to mometasone furoate (MF) or a hypersensitivity to bioabsorbable polymers. Safety and effectiveness of the implants in pregnant or nursing females have not been studied. Risks may include, but are not limited to, pain/pressure, displacement of implant, possible side effects of intranasal MF, sinusitis, epistaxis, and infection.
