Sinus Surgery in Thailand Your guide to cost, top specialists & hospitals

Our partner hospitals hold JCI accreditation and operate dedicated ENT departments with full-time rhinology specialists. They have endoscopic suites equipped with image-guided navigation, microdebrider systems, and in-house imaging. These are full-service hospitals, not day-clinics, with the infrastructure to handle any complication.

Our partner ENT surgeons are board-certified in otolaryngology by the Medical Council of Thailand, with the specialty board examination administered through the Royal College of Otolaryngologists-Head and Neck Surgeons of Thailand. Many completed rhinology fellowships overseas, then returned to Bangkok where higher patient volumes sharpen technique. They use image-guided navigation as standard for complex and revision cases.

Board certification in ENT is the starting point. Beyond that, look for a surgeon with specific sinus surgery volume and fellowship training in rhinology or skull base surgery. Ask whether they use image-guided navigation for revision cases. Reviews on independent platforms matter more than polished clinic marketing.

Most patients report significant symptom improvement after FESS¹, including reduced congestion, fewer infections, less facial pressure, and improved sense of smell. The surgery creates permanent structural changes to the sinus drainage pathways, but ongoing nasal care is important for maintaining the result.

You will notice meaningful improvement within the first week, but the full benefit takes four to six weeks as mucosal healing completes. If you had polyps removed, your sense of smell may return gradually over several weeks. Continuing nasal steroid sprays and saline irrigation long-term is the most important thing you can do to protect your result.

Our partner hospital publishes three fly-in packages for endoscopic sinus surgery, running from ฿191,000 to ฿282,000, or roughly $5,618 to $8,294, each with one night in hospital. Where you land depends on how far the surgery has to reach, from a maxillary or ethmoid clearance at the bottom to a full house FESS that opens every sinus on both sides at the top. All three include the powered microdebrider and the image-guided navigator. This is one hospital's published rate rather than what Thailand as a whole charges, and branch prices within the same network vary widely.

The package covers the operating theatre and recovery room, the surgeon and anaesthetist teams, the medicines and supplies used during the operation, and one night in a standard inpatient room with nursing care and meals. Your pre-operative CT scan, blood work, and medical clearance by an internal medicine physician sit outside it, as do pathology charges and any take-home medication. Coordinator support comes from us and is not a hospital charge.

How many sinuses need opening is the whole story. Clearing the maxillary or ethmoid sinuses is the entry point, reaching the frontal or sphenoid sinus moves you up a step, and a full house FESS across every sinus sits at the top. Because the microdebrider and the navigator are built into all three packages, scarred or revision anatomy does not attract a separate equipment charge here. Balloon sinuplasty is not on the hospital's published list, so we carry no price for it. Clearing nasal polyps is published as its own package, covered on our nasal polyp removal page.

At $5,618 to $8,294, the packages sit under the US range of $7,500 to $15,000, though the gap is narrower than the headline savings usually quoted for Thailand, and the full house package lands above the bottom of the US range. Against the UK, at £5,500 to £11,300, the position is much the same. Australian private fees are quoted here at A$6,300 to A$12,500, which converts low enough that a full house FESS in Bangkok is not clearly cheaper. The difference reflects the hospital's cost base rather than a lower standard of care. Our partner hospitals hold JCI accreditation and use the same endoscopic platforms as leading Western ENT departments.

Surgery is rarely the first thing tried for chronic sinus trouble. The standard first step is a proper course of medical therapy: daily nasal steroid sprays to calm inflammation, saline irrigation to flush the passages, and antibiotics for active infection, sometimes with a short course of oral steroids when polyps are involved. Given enough time and used correctly, this settles symptoms for a good number of people without any operation at all.

The honest limit is that medical therapy manages disease rather than removing what is blocking the sinuses. When passages are structurally obstructed by polyps, scarred tissue, or thickened bone, sprays and rinses cannot open them, and many patients find themselves on repeated antibiotic courses with the same congestion returning each time. There is also a point where staying on medication simply delays the relief that surgery would give.

Most surgeons look for around three months of well-conducted medical treatment that has failed to control things, alongside a CT scan showing disease that an operation can actually address, before recommending FESS. If your scan shows little and you have not yet given the full regimen a fair trial, more medication is usually the right call first. When both the imaging and the treatment history point the same way, sinus surgery is the step that clears the blockage and lets the sinuses drain again, and that is what the rest of this page covers.

Most patients fly home five to seven days after surgery, once packing has been removed and the surgeon has confirmed no active bleeding. Cabin pressure changes are well tolerated at this stage. Use saline spray during the flight, stay hydrated, and avoid forceful nose blowing.

Desk work is typically possible within one to two weeks. Light walking is encouraged from day one. Avoid gym workouts, swimming, and anything involving bending or straining for at least two to three weeks. Contact sports should wait until your surgeon clears you, usually around four weeks. For driving, do not drive while nasal packing is in place or while you are taking sedating pain relief; most patients are safe to drive once the packing is out and they are off strong painkillers, usually a few days after surgery, which is why your coordinator arranges all hospital transfers during your stay in Thailand.

You will notice clearer breathing within the first week once packing is removed, but internal mucosal healing takes four to six weeks. Continued saline irrigation and nasal steroid sprays during this period are important for achieving the best long-term result.

Yes. The timeline above describes standard FESS. Balloon sinuplasty widens the sinus opening without removing tissue or bone, so there is little or no bleeding and often no nasal packing. Many balloon patients have minimal downtime and return to desk work and light activity within a couple of days rather than the one to two weeks typical after FESS. You still need your endoscopic cleaning and final check before flying home, so plan the same five to seven days in Thailand, but the recovery within that window is gentler. Avoid bending, straining, and nose blowing for the first week as you would after any sinus procedure.

Functional endoscopic sinus surgery in Thailand is performed under general anaesthesia, so you are fully asleep and aware of nothing while the surgeon works inside the nose. A consultant anaesthetist stays with you for the whole operation and monitors you continuously, which is standard at the accredited hospitals we work with. Because the surgery is done through the nostrils with an endoscope, keeping you completely still and your airway protected is part of why a general anaesthetic is used rather than local.

Before you are cleared for anaesthesia you have a pre-operative assessment, including blood work and a review of your CT scan and any medications you take. This is also when blood thinners and anti-inflammatory supplements are paused under guidance, since the nasal lining bleeds easily. If you have any concern about going under, your anaesthetist will talk it through with you beforehand.

You feel nothing during the procedure itself. When you wake, the sensation is pressure, congestion, and a blocked, stuffy nose rather than sharp pain, often with some nasal packing in place. Oral pain relief is usually enough, and the discomfort eases noticeably once the packing or splints are removed at your first follow-up on days two to three.

Yes. FESS at a JCI-accredited hospital in Thailand meets the same safety standards as the UK, US, and Australia. Our partner surgeons are fellowship-trained, use image-guided navigation routinely for complex anatomy, and operate in hospitals with full in-house emergency infrastructure.

Choose a JCI-accredited hospital and a surgeon board-certified in ENT with specific sinus surgery experience. Pre-operative CT imaging is essential; it maps the disease and identifies critical landmarks. If you have had previous sinus surgery, make sure the surgeon uses image-guided navigation to account for altered anatomy.

Sinus disease can recur, particularly in patients with nasal polyposis or aspirin-exacerbated respiratory disease. Most patients report significant improvement after FESS, but polyps can regrow in some cases. Continued use of nasal steroid sprays and saline irrigation after surgery substantially reduces recurrence risk.

Plan for five to seven days. This covers your pre-operative CT scan and consultation, surgery, one to two days with nasal packing, packing removal, an endoscopic cleaning appointment, and a final check before you fly home. Longer stays are not usually necessary.

Your care coordinator handles hospital transfers, surgery scheduling, and all follow-up appointments. Our partner hospital's package covers the surgeon and anaesthetist teams, the operating theatre, the medicines and supplies used during surgery, and one night in a standard room. Your CT scan, blood work, pre-operative medical clearance and take-home medication are billed separately, as are flights and accommodation, though your coordinator can recommend nearby hotels.

Stay in Bangkok for sinus surgery. You need to be near your surgeon for the endoscopic cleaning appointment and follow-up; these are essential steps in preventing scar tissue formation. Bangkok keeps you close to the hospital if anything unexpected comes up during the first week.
