The success of functional endoscopic sinus surgery is not solely in the hands of the surgeon. The recovery period is a critical phase where the patient’s actions play a major role in the outcome. The nose heals by creating mucus and scabs. If these are not managed correctly, they can scar together and block the sinuses again, undoing the benefits of the surgery. Therefore, postoperative care is an active process.
Recovery is generally not characterized by severe pain, but rather by significant congestion and fatigue. Patients often feel like they have a severe head cold for a week or two. While you might feel physically able to walk around shortly after surgery, the internal healing of the mucosal lining takes several weeks. This section guides you through what to expect day-by-day and explains the essential maintenance routines required to ensure a perfectly healed, open sinus cavity.
When you wake up in the recovery room, you will not have any external casts or black eyes. You may have a small gauze “drip pad” taped under your nose. It is normal to have some bloody mucus draining from the nostrils for the first 24 to 48 hours. The nurses will change this pad as needed before you go home.
You will feel very stuffed up. This is due to internal swelling and the presence of dissolvable packing materials or blood clots. Because you cannot breathe through your nose, you will have to mouth-breathe, which leads to a dry throat and dry lips. Having a humidifier in your bedroom and using lip balm is very helpful during these first few days. You typically go home a few hours after waking up, once you are alert and comfortable.
The single most important task for the patient is sinus rinsing (irrigation). Most surgeons will instruct you to start rinsing your nose the day after surgery. This is not a suggestion; it is a mandatory part of the healing process. The goal is to physically flush out the dissolving packing, old blood clots, and mucus that accumulate in the nose.
You will likely use a high-volume squeeze bottle or a neti pot. The solution is a mixture of distilled water and salt (saline packets). It is critical to use distilled or boiled-then-cooled water to prevent infection. Lean over a sink and gently squeeze water into one nostril so it flows out the other. It might look bloody or gross at first—this is good. Getting that debris out prevents scarring.
You will typically rinse 2 to 4 times a day. The saline keeps the raw tissue inside the nose moist, which helps the cilia (microscopic hairs) start beating again. If the nose dries out, hard crusts form that are painful and block healing. Keeping the nose “wet and clean” is the mantra for a successful recovery.
Pain following FESS is usually moderate. Patients report a dull, throbbing pressure in the center of the face or a headache. It is rarely a sharp, cutting pain. You will likely be prescribed a narcotic pain reliever, but many patients only need it for the first 2 or 3 days before switching to Extra Strength Tylenol (acetaminophen).
You should generally avoid aspirin and NSAIDs (like ibuprofen, Advil, or Motrin) for the first two weeks, as these can thin the blood and increase the risk of a nosebleed. Fatigue is also very common. Even though the surgery is minimally invasive, your body is using a lot of energy to heal. You may feel worn out and need naps for the first week. This condition is normal, and you should listen to your body and rest.
You will have a follow-up appointment with your surgeon, usually one week after the surgery. This visit is crucial. The doctor will perform a procedure called “debridement.” They will spray your nose with numbing medicine and then use a small suction tube and forceps to clean the inside of your nose.
The surgeon looks inside to ensure everything is healing open and not scarring shut. They will gently vacuum out the remaining dissolved packing and any stubborn clots that your rinsing didn’t catch.
This process can be briefly uncomfortable or feel like weird pressure, but it provides immense relief. Many patients say they can breathe clearly for the first time in years immediately after this cleaning. It clears the airway and allows the saline rinses to work even better. You may have a few of these cleaning visits over the first month.
To prevent bleeding, you must take it easy. For the first two weeks, you should avoid any activity that raises your blood pressure or heart rate. This means no heavy lifting (nothing over 10-15 pounds), no bending over at the waist (squat down instead), and no straining on the toilet.
You should also avoid blowing your nose forcefully for at least a week or until your doctor clears you. Blowing can create pressure that forces air into the healing tissues or restarts bleeding. Sneeze with your mouth open to vent pressure. Most people take about one week off from work, returning once the fatigue subsides and they are no longer taking narcotic pain medication.
Full healing of the sinus lining takes about 4 to 6 weeks. During this time, your sense of smell may fluctuate, and you may have occasional colored discharge. This procedure is part of the cleaning process.
Long-term success often depends on medical maintenance. Surgery fixes the structural blockage, but it does not cure the underlying inflammation or allergies. You will likely need to continue using nasal steroid sprays or saline rinses indefinitely. This maintenance keeps the inflammation down and prevents polyps from growing back. Patients who treat their sinus care like brushing their teeth—a daily routine—have the best long-term results and are far less likely to need surgery again in the future.

Usually, surgeons allow gentle nose blowing after the first postoperative visit (about 1 week later). Before that, just wipe your nose or sniff gently.
No. If the saline burns, the mixture might be too salty or not salty enough, or the water temperature might be too hot or cold. It should be lukewarm.
A little oozing is normal. If you have bright red bleeding that flows steadily like a faucet and doesn’t stop after using decongestant spray and icing, call your doctor immediately.
This varies. Some patients notice it within weeks as the inflammation subsides. For others, it can take months. In some cases of severe nerve damage, it may not fully return.
You should generally avoid flying for at least 2 weeks. The changes in cabin pressure can be very painful and could disrupt the healing sinuses.
