If you've been told nasal polyps are behind your congestion, facial pressure, or lost sense of smell, you already know medication only goes so far. When sprays and steroids stop working, surgery becomes the conversation — and the options have shifted considerably in the last decade.

This guide walks through the two main surgical paths for nasal polyps: in-office procedures and steroid-eluting implants on the minimally invasive end, and traditional endoscopic sinus surgery on the other. You'll see how they compare on effectiveness, cost, and recovery, plus where each one actually fits in the treatment ladder. Choosing well starts with knowing what to look for in a surgeon and asking the right questions before you commit to any procedure.

One note up front: no article replaces a real consultation. A sinus specialist evaluates your CT scan, your symptom history, and what you've already tried — and those details change the recommendation.

What are nasal polyps?

Nasal polyps are soft, noncancerous growths that form in the lining of your nasal passages or sinuses. They look like small teardrops when young and more like peeled grapes once they mature. Most develop bilaterally — meaning both sides of the nose — and they range from barely visible to large enough to block the airway entirely.

The growths themselves aren't the disease. They're the end product of chronic inflammation, usually tied to chronic rhinosinusitis, allergies, asthma, or aspirin sensitivity. Clinicians often use the term CRSwNP — chronic rhinosinusitis with nasal polyposis — because the two conditions travel together. About 25 to 30 percent of patients with chronic rhinosinusitis develop polyps, and they're roughly twice as common in men as in women.

Symptoms worth taking seriously

Small polyps may cause nothing at all. Larger ones produce a predictable pattern: persistent nasal congestion, a reduced or absent sense of smell, postnasal drip, facial pressure, and recurrent sinus infections that don't fully clear with antibiotics. Snoring, mouth breathing, and disrupted sleep often come along for the ride.

Left untreated, polyps can worsen asthma, trigger obstructive sleep apnea, and in rare cases lead to bone erosion from ongoing sinus infection. If you're cycling through antibiotics every few months and still feel blocked, that's a signal — not a baseline to live with.

Initial approach to nasal polyp treatment

Surgery is rarely the first move. The standard starting point is medical therapy, and for many patients it handles the problem without anything more invasive.

Intranasal corticosteroid sprays are the foundation — fluticasone, mometasone, or budesonide used daily to reduce inflammation and shrink smaller polyps. A short course of oral steroids like prednisone can knock down larger polyps quickly, though the dose-dependent side effects mean it's not a long-term strategy. Saline rinses, high-volume irrigations, and antihistamines round out the first-line treatment toolkit, and for patients whose polyps are driven by allergy or asthma, controlling those underlying conditions is non-negotiable.

Biologics are the newer piece of this picture. Dupilumab, omalizumab, and mepolizumab target the type 2 inflammation behind most polyp disease, and they've changed outcomes for patients who used to face repeat surgeries. They're expensive, require ongoing injections, and aren't right for everyone — but for severe CRSwNP they've genuinely shifted what's possible without an operating room.

Medication earns its place when polyps are small, symptoms are manageable, and the underlying inflammation responds. Surgery enters the conversation when it doesn't: when polyps keep returning, when you can't breathe through your nose no matter what you take, when sinus infections become a quarterly event, or when steroid side effects start outweighing the benefit. That's the point to ask your doctor the right questions before committing to a procedure.

Minimally invasive options vs. traditional polyp surgery

Before getting into the specifics, one correction worth making up front. Earlier versions of content like this often lumped the Sinuva implant in with "laser surgery for nasal polyps." That's wrong — Sinuva doesn't use a laser and isn't a standalone surgery. Clearing up what it actually is changes how it fits into the treatment ladder.

The Sinuva sinus implant

Sinuva is a small, bioabsorbable implant loaded with 1,350 micrograms of mometasone furoate — the same steroid found in common nasal sprays, but delivered directly to the ethmoid sinus over roughly 90 days. It's placed in the office under local anesthesia using endoscopic guidance, softens gradually, and often works its way out on its own as polyps shrink. No cutting, no general anesthesia, no hospital stay.

Here's the catch most articles miss: Sinuva is FDA-approved specifically for adults who have already had ethmoid sinus surgery and are dealing with recurrent polyps. It isn't a first-line surgical option. It's designed to delay or prevent repeat surgery for patients whose polyps came back and whose symptoms aren't controlled by spray alone. In the RESOLVE II trial, about 6 in 10 patients treated with Sinuva plus daily steroid spray avoided revision surgery at 90 days, compared with about 4 in 10 on spray alone.

Pros: targeted steroid delivery where polyps actually live, no operating room, minimal recovery, and sustained medication release without relying on a patient remembering sprays every day.

Cons: the 90-day window is finite — polyps can recur after the implant is expelled or removed. It doesn't treat the underlying inflammation permanently, and it's not appropriate if you've never had prior sinus surgery. Cost and insurance coverage vary, though major carriers including United Healthcare, Aetna, and Humana now cover it for eligible patients.

Traditional polyp surgery (endoscopic sinus surgery)

The conventional surgical route is functional endoscopic sinus surgery, or FESS. Using an endoscope and small instruments inserted through the nostrils, the surgeon removes polyps, opens blocked sinus drainage pathways, and — when needed — addresses related problems like a deviated septum or turbinate hypertrophy in the same operation. It's usually performed under general anesthesia as an outpatient procedure, meaning you go home the same day.

FESS is the right call when polyps are extensive, when the sinuses themselves need to be opened up, or when imaging shows disease that an implant can't reach. Endoscopic sinus surgery also creates the anatomical access needed for ongoing topical treatments afterward — including, in some patients, a Sinuva implant down the line if polyps return.

Pros: addresses multiple, large, or hard-to-reach polyps in one procedure, widens natural sinus openings for better drainage, lets the surgeon correct related structural issues simultaneously, and is covered by most insurance plans. Modern computer-assisted navigation has made it substantially safer and more precise than the sinus surgery of 20 years ago.

Cons: general anesthesia, a real recovery period, higher risk of bleeding than an office procedure, and the possibility of needing revision surgery later — which is where Sinuva comes back into the picture.

The two aren't really competitors. They sit at different points on the same treatment path. Most polyp patients who need a procedure start with FESS; Sinuva is what comes after, if polyps return.

How much does nasal polyp surgery cost?

Sinuva typically runs higher upfront but saves on recovery costs and repeat procedures when it works as intended — most commercial plans now cover it for eligible patients. FESS is usually covered by insurance, though out-of-pocket costs can still run $3,000 to $10,000 without coverage, depending on anesthesia, facility fees, and whether related procedures are done at the same time. The bigger cost question isn't the sticker price — it's whether the procedure matches the disease. A cheaper option that doesn't address the underlying problem ends up costing more. That's one reason outpatient versus inpatient considerations matter when weighing options.

What recovery looks like

Sinuva recovery is minimal. Most patients go back to normal activity the same day, with mild congestion or slight nasal discomfort for a few days as the implant settles in. One follow-up visit around 90 days confirms the polyps have shrunk and the implant has either been expelled naturally or can be removed.

FESS recovery is longer but shorter than it used to be. Most patients take 3 to 5 days off work, avoid heavy lifting for about two weeks, and see complete healing over 6 to 8 weeks. Expect some congestion, light bleeding, and crusting in the first week — all normal. Saline irrigations start almost immediately to keep the surgical site clean, and most surgeons schedule debridement visits at 1 and 2 weeks to clear healing debris. Pain is usually well controlled with non-narcotic medication.

Frequently asked questions

Is surgery the only option? No. Surgery is reserved for polyps that don't respond to medication, biologics, or lifestyle changes. Most patients start with sprays, rinses, and allergy control.

How long do the results last? Variable. Some patients stay polyp-free for years after FESS; others see recurrence within 12 to 24 months, especially with underlying asthma or aspirin sensitivity. Ongoing steroid spray use after surgery substantially reduces recurrence.

Do nasal polyps always come back? They can. Recurrence depends on how well the underlying inflammation is controlled. Patients who stick with daily steroid sprays, treat their allergies, and manage asthma have lower recurrence rates than those who stop maintenance therapy.

What happens if I leave polyps untreated? Chronic sinus infections, worsening asthma, sleep apnea, and in rare cases bone erosion or infection spreading beyond the sinuses.

How often are follow-ups needed? Sinuva: typically one visit around 90 days. FESS: debridement at 1 and 2 weeks, then periodic checks over the first 6 months.

Do lifestyle changes help? Yes. Saline irrigation, humidifier use, avoiding known triggers, and controlling allergies reduce inflammation and recurrence. They don't replace treatment for established polyps, but they extend how long results hold.

Choosing the right path for your polyps

The decision isn't Sinuva versus FESS — it's where you are on the treatment ladder. Small polyps that respond to medication may never need either. Extensive or first-time surgical cases usually belong in the OR for endoscopic sinus surgery. Recurrent polyps after prior surgery are where Sinuva earns its place.

What matters more than the procedure name is the surgeon making the call. A sinus specialist who reviews your CT imaging, your medication history, and what's actually driving your inflammation will steer you toward the option that fits — not the one they happen to perform most. If you're unsure about a recommendation, a second opinion is a reasonable next step, especially before committing to general anesthesia.
