Sinusitis: Should I Have Surgery?
Sinusitis: Should I Have Surgery?Skip to the navigationYou may want to have a say in this decision, or you may simply want to follow your doctor's recommendation. Either way, this information will help you understand what your choices are so that you can talk to your doctor about them. Sinusitis: Should I Have Surgery?Get the factsYour options- Have surgery to treat long-term (chronic)
sinusitis.
- Don't have surgery. Take
medicines and use home treatment.
Key points to remember- Very few people need surgery for sinusitis. Most people can
treat the problem with home care and medicines.
- Surgery may be a good choice for people who have long-term
(chronic) sinusitis. They may get one infection after another because something
blocks the flow of mucus from the sinuses or because of another health problem.
Surgery can remove blockages and make the sinus openings bigger. This helps the
sinuses drain, preventing more infections.
- To be sure that surgery is a good choice, you need to have a
CT scan of your sinuses. This test will be done after
you have followed what's called "maximum medical treatment" for 4 to 6 weeks.
This means that you take medicines and follow home treatment to reduce
infection and swelling. That helps your doctor see what's causing your
infections.
- You may need more than one surgery to fix your sinuses.
- After surgery, you still may need to take medicines, such as
antibiotics, and follow home treatment for a long time.
- If you
get chronic sinusitis because of
allergies or another problem, you need to get that
problem under control before you have surgery. You will have better results
from surgery if you use medicine and home treatment after surgery to help to
keep that problem under control.
FAQs Sinusitis is infection or
inflammation of the
mucous membranes that line the
sinuses. When a mucous membrane gets
inflamed, it swells. This can block the normal flow of fluid from the sinuses
into the nose and throat. Bacteria and fungi (plural of fungus) are more likely
to grow and cause an infection in sinuses that can't drain. The
main cause of sinusitis is a viral infection, usually a cold. Allergies or
other problems also can block the nasal passages and lead to sinusitis. There are two types of sinusitis: acute (short-term) and chronic
(long-term). You may have chronic sinusitis if: - You have had more than three sinus infections
in 1 year that needed antibiotics to clear up, OR
- You have had a sinus infection for more than 12
weeks that
antibiotics have not cleared up.
Surgery may be a good choice for some people who have
chronic sinusitis. Surgery helps
the sinuses drain, preventing infections. The doctor usually makes the sinus
openings bigger by removing: - Infected, swollen, or damaged
tissue.
- Bone, to make a wider opening to let mucus drain from the
sinuses.
- Growths (polyps) inside the nose or sinuses.
There are two types of sinus surgery: - Endoscopic surgery is the type
that is done most often. The doctor puts a thin, lighted tool called an
endoscope in the nose to remove small amounts of bone or tissue that block the
sinus openings. The doctor also can remove polyps.
- Traditional surgery may be done
for certain serious problems-such as pus in a sinus, infection of the facial
bones, or a brain
abscess. The doctor makes an opening into the sinus
from inside the mouth or through the skin of the face.
Sometimes another problem inside the nose (such as a
deviated septum) also needs to be fixed. This may be done during the same
surgery. After surgery, the doctor may recommend: - Antibiotics to help
fight infection.
- Steroid nasal spray to reduce inflammation and help you heal.
- Pain medicine.
Very few
people need surgery to treat sinusitis. But you may need surgery if
ALL of these are true: - Your doctor says that you have chronic
sinusitis.
- You've followed what's called "maximum medical
treatment" for 4 to 6 weeks. This means that you've taken medicines and
followed home treatment for at least 4 to 6 weeks. This treatment includes
antibiotics, a
steroid nasal spray, and other prescription
medicines.
- You've had a
CT scan of your sinuses after the 4 to 6 weeks of
treatment. It is very important to have the CT scan done after this treatment. Reducing the swelling and infection as
much as possible lets your doctor see what could be causing your
infections.
- The CT scan shows that something, such as nasal polyps, is keeping your
sinuses from draining as they should.
You also may need surgery if: - You have a sinus infection caused by a
fungus. Infections caused by fungi cannot be cleared up with
antibiotics.
- You have a serious problem such as an infection that
spreads beyond your sinuses. This is rare.
Sinus
surgery can: - Help your sinuses drain, which can prevent
sinus infections.
- Improve your sense of smell. (But in some cases,
scarring from surgery could decrease your sense of smell.)
Endoscopic surgery improves symptoms
for about 90 out of 100 people. About 10 out of 100 people find that it doesn't
help them.footnote 1 Surgery has the best chance
of working if you use a steroid nasal spray and do home treatment after surgery
to prevent future infections. You may need to use these treatments for a long
time. Sinus surgery
can lead to minor or serious problems. - A small number of people have
minor problems, such as:
- Scar
tissue.
- Bleeding.
- Infection.
- A hole in the
tissue between the nostrils (nasal septum).
- Bruising and swelling
around the eyes.
- Serious but rare
problems can include:
- Heavy bleeding.
- Injury to the
eye area.
- Inflammation of the tissue that covers the brain (meningitis).
- Leakage of the fluid around
the brain.
- Brain injury.
- Scarring from surgery could decrease your sense
of smell.
- The surgery might not work, so you could need a second surgery.
Most of the time, you can treat your sinus problem with home care and
medicines. Home treatment- Drink plenty of fluids
to help keep the
mucus thin.
- Hold a warm, damp towel or a warm gel pack to your face for 5 to 10 minutes several
times a day.
- Breathe warm, moist air from a
steamy shower, a hot bath, or a sink filled with hot water. Avoid very cool,
dry air. A humidifier can add moisture to the air in your
home.
-
Use saltwater nasal drops or washes to help
keep your nasal passages open and to wash out mucus and bacteria. You can buy
saline nose drops or saline nasal washes (such as a Neti Pot) at a drugstore or grocery store, or you can make your
own at home. People around age 8 and older may also find it helpful to gargle often with warm salt water.
- If you need to blow your nose, do it gently. Blowing your nose too hard may
force thick mucus back into your sinuses. Keep both nostrils open when you blow
your nose.
Medicines- Take pain relievers, such as
acetaminophen or ibuprofen, that you can buy without a prescription.
- Use a steroid nasal spray or decongestant nasal sprays or pills to reduce the swelling of the mucous membranes. If you use a nasal spray, do not use it longer than what the label says.
- Take antibiotics as directed, if your doctor prescribes them.
Antibiotics can treat most short-term (acute) sinusitis when it is caused by
bacteria.
- Use mucolytics (such as guaifenesin) to thin the mucus in your sinuses.
Be safe with medicines. Read and follow all instructions on the label. Some medicines may not be safe for young children or for people who have certain health problems. Your doctor might advise you to have surgery if: - You have many sinus infections that need
treatment with antibiotics.
- Home treatment doesn't stop your pain
and other symptoms.
- You've taken medicines and done home treatment
for 4 to 6 weeks, and tests show that you have a sinus problem that surgery can
fix.

I have had
one sinus infection after another for the better part of a year. I've been
taking antibiotics and using steroids and decongestant nasal sprays for a month
now with no results. My doctor just did a CT scan and found out that one of my
sinuses is blocked. He says he can fix it with surgery. I've had a couple of bouts of sinusitis
this year, so I asked my doctor about sinus surgery. She said there are some
stronger antibiotics and other treatments I should try. I agree that it's
better to try the medicines. My doctor
fired all the medicines at this infection that she could, and I took them just
the way she told me to, but nothing seemed to work. After she looked at my CT
scan, my doctor thinks what I've got may be a fungal infection. That would
explain why the antibiotics I've tried haven't helped. I hate the idea of
having the surgery, but I have tried everything else. I have
pretty bad sinusitis, and I've had it a few times over the years. The last time
I got it, my doctor prescribed antibiotics and showed me how to wash out my
sinuses with salt water, and that worked. I'm going to try that again, and my
doctor says there are some other things we can try, too, like nasal sprays and
allergy medicines. What matters most to you?
