Endoscopic sinus surgery in Turkey: what it is and how it works
Endoscopic sinus surgery, commonly called functional endoscopic sinus surgery (FESS), is an established procedure to clear chronic blockages and recurrent infections in the paranasal sinuses. Instead of cutting through facial skin or the upper gum as older surgical approaches did, the surgeon guides slender, rigid endoscopes through the nostrils. Using delicate micro-instruments, the surgeon removes swollen mucosal tissue, bone fragments and nasal polyps that obstruct natural sinus ostia. This re-establishes airflow and natural mucociliary drainage without external facial incisions.
The surgery is designed for chronic rhinosinusitis that does not respond adequately to medical therapies such as steroids and saline rinses. This guide details how the procedure works, what scientific evidence confirms, approximate costs in Turkey compared with the UK, US and Germany, recovery stages and how to choose an ear, nose and throat (ENT) specialist.

How does endoscopic sinus surgery work to clear blocked sinuses?
The skull contains four paired sinus groups: maxillary, ethmoid, frontal and sphenoid. Each cavity is lined with ciliated epithelium producing mucus, which sweeps naturally through narrow openings (ostia) into the nasal cavity. When chronic inflammation, anatomical narrowness or polyps block these ostia, mucus stagnates and persistent bacterial or fungal infections take hold.
The surgeon carries out the procedure systematically under direct endoscopic vision:
- Decongestion: Topical vasoconstrictor pledgets are placed inside the nose to minimise capillary bleeding.
- Uncinectomy: The uncinate bone is gently removed to open direct access to the maxillary sinus ostium.
- Ethmoidectomy: Diseased partitions within the ethmoid labyrinth are cleared using precision micro-forceps or a microdebrider.
- Frontal and sphenoid clearance: Drainage channels to the forehead and deep sphenoid cavities are opened if preoperative imaging reveals blockage.
- Mucosal preservation: Unlike older radical techniques, modern surgery preserves healthy mucosal lining so microscopic cilia can resume normal physiological function.
For complex anatomy, surgeons often use intraoperative CT navigation to track micro-instruments in real time against the patient’s scans.
Does endoscopic sinus surgery actually work? What the evidence shows
Clinical studies and guidelines from the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) and the American Academy of Otolaryngology confirm that endoscopic sinus surgery is effective. Between 75% and 90% of patients with medically refractory chronic rhinosinusitis report substantial improvements in nasal congestion, facial pressure, discharge and headaches.
However, surgery addresses physical blockage rather than systemic inflammation. In patients with nasal polyposis, asthma or aspirin sensitivity, eosinophilic tissue swelling can persist. Surgery creates open cavities so topical sprays and rinses can penetrate effectively, but it is not a standalone cure. Most patients must continue daily saline irrigations and topical steroid sprays to maintain long-term results. Trustworthy surgeons will never promise that sinus surgery permanently eliminates allergies or guarantees polyps will never return.
Endoscopic sinus surgery cost in Turkey compared with the UK, US and Germany
The figures below reflect approximate cost ranges for endoscopic sinus surgery across different countries. They are indicative estimates rather than fixed hospital quotes, as pricing varies with the number of sinuses treated and surgical complexity.
| Country | Approximate cost range |
|---|---|
| Turkey | €1,500 – €3,800 |
| United Kingdom | €3,500 – €8,500 |
| United States | €4,500 – €14,000 |
| Germany | €3,000 – €7,500 |
Prices depend on whether surgery is unilateral or bilateral, whether image-guided navigation is required, and whether adjunctive procedures—such as septoplasty or turbinate reduction—are performed. In Turkey, packages generally cover preoperative ENT examinations, CT reviews, theatre fees, general anaesthesia, absorbable nasal packing, recovery medications, follow-up debridement and airport transfers. Always ask for a written quote listing all inclusions.
Endoscopic sinus surgery, balloon sinuplasty or septoplasty: how do they differ?
Patients researching nasal obstruction and sinus pressure often compare three distinct ENT procedures that treat different anatomical problems.
| Method | Best suited to | Typical limits |
|---|---|---|
| Endoscopic sinus surgery | Extensive chronic sinusitis, ethmoid disease, nasal polyps, anatomical ostial obstruction | Requires general anaesthesia; involves post-operative crusting and clinic cleaning |
| Balloon sinuplasty | Mild, isolated chronic sinusitis of maxillary, frontal or sphenoid sinuses | Cannot remove polyps, bone or tissue; cannot treat ethmoid air cells |
| Septoplasty | Physical airway obstruction caused by a deviated nasal septum | Straightens cartilage and bone; does not drain or clear infected sinus cavities |
If chronic inflammation or polyps block your sinus cavities, you may need functional endoscopic sinus surgery or targeted nasal polyp surgery. When isolated sinus ostia are narrowed without severe tissue disease, balloon sinuplasty provides gentle balloon dilation. If a crooked septum restricts breathing and endoscopic access, surgeons frequently combine sinus surgery with a septoplasty in one session.
Who is a suitable candidate for endoscopic sinus surgery?
Endoscopic sinus surgery is intended for patients with confirmed sinus disease rather than ordinary seasonal rhinitis. Good candidates typically present with:
- Chronic rhinosinusitis: Symptoms lasting over twelve weeks—such as nasal congestion, facial pain, discoloured discharge and reduced smell—that disrupt daily life.
- CT scan confirmation: A coronal paranasal CT scan documenting mucosal swelling, fluid accumulation, or obstructed sinus openings.
- Failed medical management: Inadequate symptom relief after completing structured medical therapy, including intranasal corticosteroids, nasal saline rinses and targeted antibiotics.
- Recurrent acute sinusitis: Four or more documented acute bacterial sinus episodes per year.
- Specific anatomical obstructions: Symptomatic nasal polyposis, antrochoanal polyps or sinus mucoceles requiring mechanical clearance.
Surgery is not recommended for individuals whose symptoms stem purely from unmanaged environmental allergies without structural blockage, nor for patients with uncontrolled bleeding disorders or severe medical conditions that make general anaesthesia unsafe.
The surgical procedure step by step: technique and anaesthesia
Endoscopic sinus surgery is performed entirely through the nostrils, leaving no external incisions or facial marks. The procedure usually takes between 60 and 120 minutes depending on how many sinuses require attention.
The standard surgical steps include:
- General anaesthesia: The operation is carried out under general anaesthesia with airway protection to ensure comfort and immobility.
- Local preparation: Topical decongestant pledgets are placed in the nasal passages for ten minutes to shrink blood vessels and maintain a clear surgical view.
- Endoscopic dissection: Using high-resolution endoscopes at various angles (0°, 30°, 45° or 70°), the ENT surgeon guides micro-instruments or a microdebrider to excise polyps and open blocked bony channels.
- Ostial enlargement: The natural drainage passages of the maxillary, ethmoid, frontal or sphenoid sinuses are widened to restore ventilation.
- Hemostasis and dressings: Surgeons use dissolvable haemostatic foams or gels that break down naturally with saline washes, avoiding painful pack removal. If septoplasty is combined, thin silicone splints may be placed temporarily.
What results can you realistically expect from sinus surgery?
Because endoscopic sinus surgery is an internal functional procedure, your external facial appearance will not change. Photographs before and after surgery do not show aesthetic transformations unless you have concurrently arranged a cosmetic rhinoplasty.
Realistic outcomes involve internal improvements:
- Restored nasal airflow: Most patients notice easier, clearer breathing through the nose once initial swelling subsides.
- Relief from facial pressure: Chronic aching, cheek fullness and frontal sinus headaches typically lessen over the first four to six weeks.
- Fewer sinus infections: While the operation does not prevent ordinary viral colds, mucus drains freely so secondary bacterial infections occur far less frequently.
- Sense of smell: Reduced smell caused by polyp obstruction often recovers after surgery. However, if chronic inflammation has damaged olfactory nerves over many years, smell recovery may be gradual or incomplete.
Legitimate clinics provide endoscopic images or follow-up CT scans showing wide, healthy sinus pathways rather than cosmetic pictures.
Your trip to Turkey and endoscopic sinus surgery recovery timeline
Patients travelling to Turkey for endoscopic sinus surgery typically stay for five to seven nights. This timeframe allows for preoperative assessments, surgery, early healing and an essential post-operative cleaning appointment before flying home.
Recovery progresses through distinct stages:
- Days 1–2: Mild pink discharge and nasal congestion are normal. You will breathe through your mouth and wear a small drip pad beneath the nose. Rest with your head elevated and do not blow your nose.
- Days 3–5: Begin gentle nasal saline irrigations as instructed by your surgeon. These washes remove dried blood, dissolving pack remnants and crusts. Light walking around your hotel is encouraged.
- Days 5–6: You attend a hospital check-up where the surgeon endoscopically cleans (debrides) crusts and dissolvable material and removes silicone splints if used. The surgeon confirms healing and provides a fit-to-fly certificate.
- Weeks 2–4: You can return to desk work after seven to ten days. Nasal breathing steadily improves. Avoid strenuous exercise, heavy lifting, swimming and saunas for three weeks to prevent nosebleeds.
- Months 2–3: Sinus mucosa and microscopic cilia heal completely, establishing long-term breathing stability.
Risks and potential complications of endoscopic sinus surgery
Endoscopic sinus surgery has an established safety profile when performed by trained ENT specialists. Nonetheless, every surgical procedure carries potential risks. Medical bodies such as the NHS, ENT UK and the American Academy of Otolaryngology identify the following:
- Bleeding: Minor spotting is standard during the first week. Significant bleeding is uncommon but may require temporary packing.
- Infection: Post-operative sinus infection can occur as crusts accumulate; this is managed with saline irrigations and oral antibiotics.
- Adhesions (synechiae): Scar tissue bands can occasionally develop between raw mucosal surfaces. Minor adhesions can be divided simply during a routine follow-up.
- Polyp recurrence: In patients with underlying inflammatory disease, polyps can re-form over several years, requiring ongoing topical steroid sprays.
- Rare anatomical risks: Because sinuses lie adjacent to the eye sockets and skull base, rare complications include periorbital bruising, eye tear duct injury, double vision, or a skull base breach causing cerebrospinal fluid (CSF) leakage. Intraoperative CT navigation and magnification keep these risks very low.
How to choose an ENT specialist in Turkey and questions to ask
When selecting an ENT specialist in Turkey, verify that the surgeon is a certified otorhinolaryngologist with subspecialty training in rhinology and advanced endoscopic sinus surgery. Ensure the hospital is licensed, maintains intensive care facilities and uses high-definition endoscopic towers and image-guided navigation systems.
Be cautious of red flags: clinics that quote prices without examining your sinus CT scan, promises of a guaranteed cure for allergies, or schedules that do not include a post-operative endoscopic debridement before you travel home.
Helpful questions to ask your surgical team include:
- Which specific sinuses need opening based on my CT scan?
- Do you advise combining this with septoplasty or turbinate reduction?
- Do you use dissolvable packing, and will I need painful pack removal?
- What post-operative endoscopic cleaning will you perform before I fly?
- What medications and saline rinse schedule do I follow after returning home?
- Who should I contact if I experience bleeding after discharge?

Frequently asked questions
Endoscopic sinus surgery, or functional endoscopic sinus surgery (FESS), is a minimally invasive surgical procedure that uses slender illuminated telescopes and micro-instruments inserted through the nostrils. It widens the natural drainage pathways of the paranasal sinuses and removes diseased tissue or polyps without external incisions on the face, restoring airflow and mucociliary clearance.
Yes, clinical evidence shows high efficacy for chronic rhinosinusitis and nasal polyposis that have failed medical treatment. Most patients experience significant reductions in nasal obstruction, facial pressure, headaches and recurring infections. However, surgery does not alter systemic inflammatory tendencies, meaning continuing prescribed saline rinses and topical steroid sprays remains necessary for long-term control.
Approximate costs in Turkey typically range from €1,500 to €3,800, compared with €3,500 to €8,500 in the UK and even higher in the US. The total cost depends on how many sinuses require opening, whether image-guided navigation is required, and if concurrent procedures like septoplasty are performed. The clinic provides a definitive quote following CT review.
Because the entire operation is performed inside the nostrils, endoscopic sinus surgery produces no external cosmetic changes to the nose or face. Before-and-after results are internal: endoscopic imaging and CT scans demonstrate wide, open sinus cavities free of mucosal obstruction, while patients experience clearer breathing, resolved facial pressure and improved quality of life.
Endoscopic sinus surgery removes diseased tissue, bone, and polyps from complex areas like the ethmoid and frontal sinuses under direct magnification. Balloon sinuplasty only dilates sinus openings using an inflated catheter without removing tissue. Balloon sinuplasty suits mild, isolated maxillary or frontal congestion, whereas FESS treats extensive sinusitis and nasal polyps.
Initial recovery takes about one to two weeks. Most patients resume sedentary desk work after seven to ten days. Nasal congestion and crusting are normal during the first fortnight and resolve with regular saline irrigations. Full mucosal healing and normal cilia regeneration inside the sinus cavities usually take six to eight weeks.
The procedure is performed under general anaesthesia, ensuring no intraoperative sensation. Afterwards, patients typically experience dull facial pressure, headache and a feeling similar to a severe head cold rather than sharp surgical pain. This discomfort is readily managed with standard oral analgesics and significantly decreases once internal swelling subsides over the first few days.
Surgical opening of the sinus passages is permanent, as removed obstructive bone does not re-grow. However, chronic rhinosinusitis involves ongoing mucosal inflammation. Patients with allergic disease or nasal polyps may experience recurrence over several years if they do not maintain postoperative medical care, particularly daily saline rinses and prescribed anti-inflammatory nasal sprays.
When performed by an experienced ENT surgeon, the procedure is considered safe. Common side effects include temporary bleeding, congestion and crusting. Rare anatomical risks include scar adhesions, bleeding requiring pack repacking, and very rarely damage to the surrounding orbital tissues or skull base resulting in cerebrospinal fluid leakage. Preoperative CT planning minimises these risks.
A stay of five to seven nights is generally recommended. This allows adequate time for your preoperative CT evaluation, the surgery itself, initial postoperative rest, and an essential follow-up appointment around day five or six. During this visit, the surgeon performs endoscopic debridement, removes any splints, and issues formal clearance for your flight home.
