What Is a Mometasone Sinus Implant?

Think of this implant as a very tiny, spring-like device that is soft and flexible. It is designed to dissolve completely inside your body over time. Inside this tiny device is a special type of medicine called mometasone.

Mometasone belongs to a group of medicines known as corticosteroids. These medicines work by calming down swelling and inflammation in your body. When tissues inside your nose get swollen after an operation, it can block your airflow and cause discomfort.

Your ear, nose, and throat doctor, also called an ENT surgeon, places this tiny device right inside your sinus cavity during your surgery. Once it is in place, it begins to release the mometasone medicine slowly and steadily over several weeks.

This treatment offers two major benefits for your recovery. First, it stops post-surgery swelling so your sinus passages stay open. Second, it helps prevent nasal polyps from growing back after doctors remove them during surgery.

The best part is that you do not need another surgery to take it out. The device simply dissolves on its own after doing its job. You might hear your doctor refer to brand names like Propel or Sinuva when discussing this option.

What to Tell Your Doctor Before Treatment

Because an experienced doctor places this implant during a medical procedure, they need to know your full health history. Sharing accurate details helps keep you safe and ensures the treatment works properly for your specific health needs.

Your Health Condition Why Your Doctor Needs to Know
Active infections
Examples include tuberculosis, herpes, or fungal infections.
Steroid medicines can lower your body's immune defenses slightly, which might cause existing infections to worsen.
Known allergies
Allergies to mometasone, similar steroids, or implant materials like polymers.
Placing a material you are allergic to inside your body can trigger serious allergic reactions. Always mention past reactions.
Pregnancy
If you are pregnant or actively trying to become pregnant.
Doctors use medicines with extra caution during pregnancy to weigh all potential benefits against risks for you and your baby.
Breastfeeding
If you are currently nursing your baby.
Your doctor must check whether small amounts of the medicine can pass into breast milk before starting this treatment.

What to Do After Receiving Your Implant

You cannot place this implant at home. Your doctor places it safely inside a hospital or clinic setting. After your procedure, you play an important role in making sure your healing process goes smoothly.

Make sure you attend all scheduled follow-up visits with your doctor. These appointments allow your doctor to check your healing progress and confirm your sinuses are opening properly. Never skip these important checkups.

Avoid using over-the-counter nasal sprays unless your doctor specifically tells you to do so. Mixing unapproved sprays with your healing tissues can cause irritation and slow down your recovery.

Your doctor will likely recommend using a saline spray or nasal rinse to keep your nasal passages moist and clean. Follow these cleaning instructions carefully every single day to clear out dried mucus and promote healthy tissue repair.

The most important rule after surgery is to follow your doctor's instructions to the letter. Do not try unapproved home remedies. If you notice any unusual changes or have questions, contact your doctor right away.

Possible Side Effects to Watch For

Just like any medical treatment, this implant can cause mild side effects. Most of these effects are minor and go away on their own as your body heals from the procedure.

Side Effect Category What You Might Experience
Allergic reactions Skin rashes, itching, or swelling of your face, lips, or tongue.
Vision changes Blurry vision or other unexpected changes in how clearly you see.
Eye pain Persistent pain or discomfort in or around your eyes.
Implant movement Feeling the tiny device shift out of place or slip down toward your nose opening.
Signs of infection Fever, chills, a persistent cough, or a sore throat.
Nasal irritation Mild burning or general discomfort inside your nose or sinuses.
Headaches Mild head pain or a feeling of pressure around your sinus areas.
Minor nosebleeds A few drops of blood when you blow your nose gently during healing.
Throat discomfort A slight scratchy feeling or mild soreness in your throat.

If you experience minor symptoms like slight nasal irritation or mild headaches, they are usually normal during recovery. However, if these symptoms become severe or refuse to go away, you should call your doctor for guidance.

When to Seek Emergency Help

Serious allergic reactions to this implant are extremely rare, but they require immediate medical attention.

  • If you suddenly experience trouble breathing or shortness of breath.
  • If your lips, tongue, or throat swell up rapidly.
  • If you experience sudden, severe vision loss or eye pain.

Call 911 (US/Canada), 999 (UK), or your local emergency number right away, or go straight to the nearest Emergency Department (ER or A&E).
