When medication stops working, surgery clears the path so your sinuses can drain the way they should.
Chronic sinusitis that does not respond to medication leaves you living on antibiotics, decongestants, and hope. Functional endoscopic sinus surgery opens the blocked drainage pathways so mucus and infection can clear naturally. Thailand handles a high volume of FESS cases in JCI-accredited hospitals with fellowship-trained ENT surgeons.
Free, no-obligation — you pay the hospital directly with no markup.
Functional endoscopic sinus surgery uses a thin, lighted endoscope inserted through the nostrils to open the natural drainage pathways of the sinuses. Diseased tissue, polyps, and bony obstructions are removed under direct camera guidance, allowing air and mucus to flow freely again.
FESS is most commonly performed for chronic rhinosinusitis that has not responded to at least three months of proper medical therapy — including nasal steroids, saline irrigation, and antibiotics. It is also the standard approach for nasal polyposis and recurrent acute sinus infections. The procedure does not involve external incisions.
Sinus surgery is not glamorous, but Thailand's ENT departments handle it with the same precision and infrastructure they apply to more complex procedures — at a fraction of Western costs.

Your Quote Will Include
Prices are approximate and vary by technique, surgeon, and hospital. Your personalised quote will include a full cost breakdown.
Sinus surgery in Thailand typically costs between $2,500 and $4,500, depending on the extent of disease, the technique used, and whether image-guided navigation is required. Simple single-sinus balloon sinuplasty sits at the lower end, while comprehensive multi-sinus FESS with navigation is at the higher end.
The surgeon's fee is the largest component. Hospital and theatre fees cover the facility, operating room, endoscopic equipment, and nursing. Anaesthesia covers the anaesthetist and monitoring. Aftercare includes follow-up visits, endoscopic cleaning, medications, and coordinator support.
The number of sinuses involved and the complexity of the case are the main drivers. Balloon sinuplasty costs less because it is a simpler procedure. Revision surgery costs more because scarred anatomy requires navigation equipment and longer operative times. Polypectomy adds modest cost if extensive.
Typical pricing ranges at our partner hospitals in Thailand:
Final pricing is confirmed after your CT scan and consultation.
Sinus surgery in Thailand costs 50 to 70 percent less than equivalent procedures in the US ($7,500–$15,000), Australia (A$6,300–A$12,500), and UK (£5,500–£11,300). The savings reflect lower operating costs in Thailand, not lower standards. Our partner hospitals hold JCI accreditation and use the same endoscopic platforms as leading Western ENT departments.
The extent of surgery depends on which sinuses are affected and whether polyps, fungal disease, or structural issues are involved. Your CT scan tells most of the story before the surgeon picks up an instrument.
The most common form of sinus surgery, opening blocked drainage pathways through the nostrils under endoscopic guidance. Diseased mucosa, polyps, and obstructing bone are carefully removed. Image-guided navigation is available for added precision in complex anatomy.
A less invasive option for selected patients with limited disease. A balloon catheter is guided into the blocked sinus opening and inflated to widen the pathway without removing tissue or bone. Quicker recovery but limited to isolated sinus obstruction without polyps.
For patients with extensive polyposis, fungal sinusitis, or disease that has recurred after a previous operation. The surgery is more comprehensive, often involving wider openings across multiple sinus cavities and navigation to manage altered anatomy from prior surgery.
Technique selection depends on which sinuses are affected, the extent of disease, and whether this is a first operation or a revision. Your CT scan is the surgical roadmap.
A powered microdebrider shaves polyps and diseased tissue with precision while suctioning debris simultaneously. This gives the surgeon cleaner views during the procedure and reduces operative time compared with traditional cold-steel instruments, especially in cases with extensive polyposis.
A real-time GPS-like system maps the surgeon's instruments against your pre-operative CT scan, showing their exact position relative to critical structures like the eyes and brain. This is not optional equipment in complex cases — it is the safety standard that makes aggressive disease clearance possible.
After opening the sinus passages, steroid-eluting stents may be placed to deliver anti-inflammatory medication directly to the healing tissue. This reduces post-operative inflammation, polyp regrowth, and the need for additional interventions during the healing period.
You rest at the hospital or your hotel with nasal packing or splints in place. Congestion, bloody nasal discharge, and facial pressure are all normal. Pain is managed with oral medication. Breathing is through your mouth until the packing comes out.
Nasal packing or splints are removed by your surgeon, bringing noticeable relief. Gentle saline irrigation begins to keep the sinus cavities moist and clear debris. Increased congestion from healing swelling is expected and temporary.
Congestion and discharge gradually decrease. You attend a follow-up for endoscopic cleaning of the nasal cavities — this removes crusting and promotes healthy healing. Light activity is fine, but avoid heavy lifting, bending, or blowing your nose.
Breathing continues to improve as internal swelling subsides. Saline rinses are maintained several times daily. Most patients return to desk work within one to two weeks. Full mucosal healing takes four to six weeks, with ongoing improvement in airflow over the following months.
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.
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.
FESS has a strong safety record across decades of use. Serious complications are rare at experienced centres, but you should understand them.
Risk in sinus surgery correlates directly with surgeon experience and the use of image-guided navigation in complex cases. Every patient at our partner hospitals undergoes CT imaging, blood work, and a thorough history review before proceeding.
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. Over 90 percent of 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.
Your outcome depends on surgeon skill and hospital infrastructure. Here is what our partner centres provide.
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 certified by the Royal College of Otolaryngologists 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.
Sinus surgery results are measured by symptom relief rather than appearance. The improvement is functional — clearer breathing, fewer infections, and less reliance on medication.
Over 90 percent of patients report significant symptom improvement after FESS, 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.
Sinus surgery is one of the shorter medical trips — five to seven days covers everything essential.
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. The surgical quote covers the surgeon's fee, anaesthesia, hospital stay, CT imaging, medications, and aftercare. Flights and accommodation are separate, but 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.
