Nasal Polyps

About nasal polyps and treatment options

What are Nasal Polyps?

Nasal polyps can be found in either the sinuses or within nasal cavities. Unlike polyps that occur in the colon, those found in the sinuses are almost always benign. These polyps have a grape-like appearance, hanging down from the lining. While small nasal polyps may be asymptomatic, larger polyps or clusters of polyps can obstruct the nasal passage, causing a range of issues.

What Causes Nasal Polyps To Form?

While nasal polyps can affect anyone, they are more prevalent among males aged 40 and above. While chronic inflammation is a contributing factor in some individuals, it does not apply to everyone. The precise cause of nasal polyps is not yet entirely clear, but studies suggest an association with allergic rhinitis, asthma, sinusitis, and cystic fibrosis. Certain research has also indicated a distinct immune system response in the mucous membranes of those who develop nasal polyps.

Symptoms of Nasal Polyps

Possible symptoms include:

  • Sneezing
  • Postnasal drip
  • Facial pain
  • Stuffy or blocked nose
  • Runny nose
  • Loss of taste
  • Chronic infections
  • Decreased sense of smell
  • Itching around the eyes
  • Sensitivity to fumes, odors, dust, and chemicals

Diagnosis of Nasal Polyps

At The ENT & Allergy Centers of Texas, our team will ask about your symptoms and conduct a nasal examination to detect the presence of polyps. We use a nasal endoscope to visualize the growths, which involves inserting the instrument through one nostril and advancing it into the nasal cavity. In addition to endoscopy, we may employ a CT scan to identify the size and location of polyps situated deeper in the sinuses. This technique enables us to determine the extent of sinus disease, or eliminate other potential causes, including structural abnormalities in the sinuses.

Treatment Options for Nasal Polyps

There are several ways to treat nasal polyps. Although there is no universal solution, having an awareness of your treatment options and understanding the nature of your nose can facilitate informed decision-making concerning the most suitable course of treatment for you. Options include:

  • Steroid nasal sprays to shrink polyps and improve symptoms.
  • Oral steroids (pills you swallow).
  • Injections (shots) under the skin to deliver a medicine called dupilumab.
  • Outpatient (no overnight stay)in-office procedure to place a tiny steroid stent (PROPEL).
  • Outpatient surgery using endoscopy to remove polyps when other treatments don’t work.

What is SINUVA and How Does it Work?

Individuals who have undergone sinus surgery in the past are susceptible to recurring polyps. SINUVA is a tiny steroid implant inserted into the area where the polyps have formed. This implant gradually dissolves, releasing anti-inflammatory medication to treat and diminish nasal polyps. It remains in place for a maximum of 90 days before removal. The insertion of SINUVA is a straightforward in-office procedure, and it is imperceptible in the sinus cavity.

SINUVA is made from bioabsorbable polymers that gradually soften with time. The device features folded arms that are retracted during insertion into the sinus cavity. Upon reaching the appropriate position, SINUVA is deployed, causing the arms to expand outward and anchoring it in place within the sinus cavity. The implant then begins dispensing mometasone furoate, a corticosteroid that reduces nasal obstruction and congestion by shrinking the polyps. This medication also enhances the patient’s olfactory function. After the polyps have contracted or disappeared, the SINUVA implant is eliminated via a straightforward office appointment.

How is SINUVA Placed?

The SINUVA placement takes just a few minutes in our ENT & Allergy Centers of Texas offices. First, we apply local anesthesia to your nose, which usually takes between 20 minutes to take effect. Then, we introduce the SINUVA implant via a delivery system. The implant is compressed and has a size comparable to that of a cotton swab head. Upon reaching its intended position, the implant is released, causing it to expand and stay in place.

How Long Will SINUVA Last & Are There Any Risks?

Upon placement, SINUVA starts working immediately. As soon as the polyps have either contracted or disappeared entirely, the implant is removed. This implant is present for up to 90 days or less. As SINUVA softens and the polyps diminish in size, the implant may be spontaneously expelled through sneezing or forceful nose blowing.

The most frequently reported adverse reactions in the clinical trials for SINUVA were upper respiratory or middle ear infections, bronchitis, headaches, lightheadedness, nosebleed, and asthma.
