- Sinus surgery is generally considered only after about three months of medical therapy fails — it is not a first step, and your ENT decides whether you qualify.
- Functional Endoscopic Sinus Surgery (FESS) works through the nostrils with no external incisions; balloon sinuplasty is a less invasive option for selected, limited disease.
- Most people return to desk work in about 5-7 days, but full mucosal healing takes three to six months, and daily saline irrigation is central to recovery.
- Serious complications (CSF leak, orbital injury) are rare — each under about 1% — but real, because the sinuses sit close to the eye and brain.
- Many patients improve without surgery using saline irrigation, intranasal steroids, and, for nasal polyps, biologics like dupilumab.
- Costs vary widely by procedure, setting, and region; treat any figure as an estimate and confirm with your surgeon and insurer.
——————————————————————————–
Roughly 12% of American adults live with chronic rhinosinusitis, and the condition costs the U.S. economy billions of dollars a year in direct care and lost productivity, per the CDC. Sinus surgery is generally reserved for patients whose symptoms persist despite about three months of medical therapy. Modern endoscopic techniques and balloon sinuplasty have largely replaced the disfiguring open approaches of decades past, making recovery faster and outcomes more predictable — though whether surgery is right for you is a decision your ENT makes based on your imaging, symptoms, and treatment history.
What Sinus Surgery Is and Who Needs It
The paranasal sinuses are air-filled cavities lined with mucosa that drain into the nasal cavity through small openings. When inflammation, polyps, anatomical narrowing, or fungal disease blocks those openings, mucus stagnates and infection can follow. Chronic rhinosinusitis is defined as symptoms lasting more than 12 weeks and typically includes nasal obstruction, facial pressure, anterior or posterior nasal drainage, and a reduced sense of smell.
The American Academy of Otolaryngology–Head and Neck Surgery recommends surgery only after a thorough medical trial, which typically includes saline irrigation, intranasal corticosteroids, and antibiotic courses for documented infections, along with biologics for severe nasal polyps in appropriate candidates. CT imaging confirms anatomical disease before surgery is offered. In other words, surgery is a step taken when the evidence supports it — not a default.
How the Procedure Is Performed
Functional Endoscopic Sinus Surgery (FESS) is the workhorse. Through the nostrils, the surgeon uses small endoscopes and tiny instruments to enlarge the natural sinus drainage pathways, remove polyps, and clear out diseased mucosa while preserving healthy tissue. There are no external incisions. Procedures typically take 60–180 minutes, usually under general anesthesia.
Balloon sinuplasty is a less invasive option for selected patients with limited disease. A flexible catheter with a small balloon is threaded into the sinus opening and inflated to widen it without removing tissue. It can sometimes be done in the office under local anesthesia. According to comparative outcomes data, balloon sinuplasty tends to work well for frontal and maxillary sinus disease without polyps but is generally not appropriate for ethmoid disease or aggressive polyps. Image-guidance navigation systems are now common for revision surgery, skull-base proximity, and anatomically complex cases. Which technique fits your anatomy is a judgment your surgeon makes.
Preparation and the Day Of
Pre-op CT imaging maps the anatomy. Aspirin, ibuprofen, fish oil, and herbal blood thinners are typically stopped one to two weeks before surgery, but only on your surgeon’s instruction. Patients with asthma, aspirin sensitivity, or polyposis often start oral steroids in the days before surgery to reduce mucosal inflammation. Smoking cessation is strongly encouraged because smoke directly damages sinus cilia.
You’ll usually fast from midnight, arrive a few hours early, and meet your surgical team. Most sinus surgery is outpatient — you go home the same day with packing or absorbable sponges in the nose, prescriptions for antibiotics and pain medication, and instructions to begin saline irrigations within 24–48 hours. Patients undergoing concurrent septoplasty or turbinate reduction will have similar but slightly extended recovery.
Recovery Timeline
Most patients return to desk work within five to seven days. Significant nasal congestion, drainage of old blood and mucus, and facial pressure are normal for one to two weeks as crusts form and slough. Saline irrigation two to four times daily is the cornerstone of healing — it helps prevent adhesions, clears debris, and speeds mucosal recovery. Most surgeons schedule “debridement” visits at one to three weeks to clean out crusts and adhesions in the office.
Heavy exertion, nose-blowing, and bending below the waist are typically restricted for one to two weeks to reduce bleeding risk. Air travel is usually allowed after one to two weeks. Smell often improves within four to six weeks, though full mucosal healing takes three to six months. Patients with polyposis usually continue intranasal steroids long-term to delay recurrence.
Risks, Complications, and Outcomes
Symptom improvement after FESS occurs in roughly 80–90% of appropriately selected patients, per Cleveland Clinic data. Major complications are rare but real, because the sinuses sit close to the brain and orbit. Risks include bleeding, infection, scarring (synechiae), recurrence of polyps, anosmia (loss of smell), CSF leak (less than about 1%), and orbital injury (also less than about 1%). Your surgeon should walk you through the risks specific to your anatomy and planned procedure.
When to seek emergency care: Call your surgeon or go to the nearest emergency room if you experience bright red bleeding that does not stop with 30 minutes of pinching the nose, vision changes or double vision, severe headache with a stiff neck, clear watery drainage from the nose that increases with leaning forward (possible CSF leak), or signs of infection like fever above 101.5°F with worsening facial pain.
Alternatives to Sinus Surgery
Most patients improve with medical therapy alone. Saline irrigation with neti pots or squeeze bottles is supported by strong evidence for chronic sinusitis. Intranasal corticosteroid sprays (fluticasone, mometasone) are first-line for inflammation. Oral antibiotics target documented bacterial infections. Biologic medications — including dupilumab, omalizumab, and mepolizumab — are FDA-approved for chronic rhinosinusitis with nasal polyps and can shrink polyps without surgery in many patients, though they are expensive and usually require ongoing treatment. Allergy testing and treatment, including immunotherapy, address contributing rhinitis. For patients with concurrent obstructive symptoms from enlarged tonsils or a deviated septum, combined approaches with tonsillectomy or septoplasty are common.
Cost Considerations
Sinus surgery is considered medically necessary in patients meeting criteria and is covered by Medicare and most commercial insurance, so many insured patients pay only their deductible and coinsurance. Cost estimates vary widely, so treat every figure as a ballpark. Without insurance, published estimates for FESS in an outpatient setting commonly fall in the range of roughly $8,000 to $15,000, depending on the extent of disease, region, and use of image guidance. Balloon sinuplasty is generally less, often around $2,000 to $7,000, and even lower in an office setting. Ambulatory surgery centers typically cost meaningfully less than hospital outpatient departments, and adding image-guidance navigation can raise the total.

Frequently Asked Questions
How long does sinus surgery last?
Most patients enjoy years of improvement. Polyposis, however, recurs in roughly 30–60% of patients within five years, often requiring repeat surgery or biologic therapy. Patients without polyps and with good post-op irrigation habits typically have the most durable results.
Will I have black eyes after surgery?
Bruising under the eyes is uncommon after isolated FESS but more frequent after combined ethmoid and orbital-wall work. Most bruising resolves in one to two weeks. Significant orbital swelling or eye pain is not normal and should prompt a call to your surgeon.
How soon can I fly after sinus surgery?
Most surgeons allow flying after one to two weeks, once acute swelling and bleeding risk have subsided. Cabin-pressure changes can be uncomfortable in the first week. Continuing saline irrigation while traveling helps.
Is sinus surgery painful?
Most patients describe pressure, congestion, and headache rather than sharp pain. Acetaminophen and, when needed, short courses of prescription pain medicine control discomfort in the first three to five days. Pain that worsens after day five is unusual and should be evaluated.
What to Discuss With Your Surgeon
Sinus surgery rewards careful patient selection. Ask your otolaryngologist whether your CT findings, symptom pattern, and medical trial truly justify surgery, whether balloon sinuplasty or full FESS is more appropriate for your anatomy, what their revision rate is at five years, and how aggressive the post-op debridement schedule will be. Patients who commit to long-term saline irrigation and topical steroids tend to do best regardless of which technique is used. Ultimately, your ENT surgeon is the one who weighs the benefits and risks for your particular case.
