Functional endoscopic sinus surgery (FESS) is the gold-standard surgical treatment for chronic rhinosinusitis (CRS) that has failed adequate medical management. It uses small endoscopes and instruments inserted through the nostrils — without any external incisions — to open the natural drainage pathways of the paranasal sinuses, remove diseased tissue, and restore normal sinus ventilation and mucociliary clearance.

CRS is one of the most prevalent chronic conditions in the world — affecting approximately 12% of adults — characterised by persistent inflammation of the paranasal sinuses causing nasal congestion, facial pressure, reduced sense of smell, and nasal discharge for more than 12 consecutive weeks. The two major subtypes are CRS without nasal polyps (CRSsNP) and CRS with nasal polyps (CRSwNP) — characterised by the growth of benign, oedematous, grape-like polyps from the sinus mucosal lining that progressively fill and obstruct the nasal passages and sinuses.

CRSwNP is the most common indication for FESS — nasal polyps can be reduced by topical corticosteroid sprays and short courses of oral corticosteroids, but they recur in the majority of patients. FESS removes the polyps and opens the sinus drainage pathways; post-operative topical steroids and saline rinses maintain the opened sinuses long-term.

India and the UAE have ENT departments with 4K endoscope systems, microdebriders, and complete FESS instrument sets performing high volumes of sinus surgery at costs 65–75% below equivalent private surgery in the UK or USA.

FESS Indications and Planning

CT paranasal sinuses (with fine-cut coronal, axial, and sagittal reconstructions) is essential before FESS — it is the surgical roadmap. The CT shows the extent and distribution of sinus disease, the anatomy of the ostiomeatal complex (the drainage pathway of the maxillary, anterior ethmoid, and frontal sinuses), the relationship of the sinuses to the orbit and optic nerve, and any anatomical variants (agger nasi cells, Haller cells, Onodi cells near the optic nerve) that must be identified to avoid surgical complications.

Nasal endoscopy grades polyp extent: Grade 0 (no polyps); Grade I (polyps confined to the middle meatus); Grade II (polyps extending below the middle meatus but not filling the nasal cavity); Grade III (polyps completely filling the nasal cavity causing total obstruction). Higher grade polyps are less likely to respond adequately to topical steroids alone and more often require FESS.

Allergy testing and immunology review should precede surgery in patients with eosinophilic polyp disease — treating the underlying allergic disease significantly reduces post-operative polyp recurrence. Aspirin-exacerbated respiratory disease (Samter's triad — asthma, nasal polyps, and aspirin sensitivity) requires specific management planning.

FESS Procedure

FESS is performed under general anaesthesia, with the patient supine and the head elevated 15–20 degrees. The nasal cavity is decongested with topical vasoconstrictors. A 0-degree and/or 30-degree 4mm Hopkins rod endoscope is introduced through the nostril; all surgery is performed under direct endoscopic visualisation on a high-definition monitor.

The procedure systematically opens each sinus group: uncinectomy (removing the uncinate process — the first step, opening the infundibulum); maxillary antrostomy (widening the maxillary sinus drainage ostium); anterior ethmoidectomy (removing anterior ethmoid cells); frontal sinusotomy (opening the frontal recess — the drainage pathway of the frontal sinus, often the most technically demanding part); posterior ethmoidectomy (removing posterior ethmoid cells); and sphenoidotomy (opening the sphenoid sinus, which lies adjacent to the optic nerves and carotid arteries — requires particular care).

Any nasal polyps within the surgical field are removed with the powered microdebrider (a rotating suction-cutting instrument that efficiently removes soft polyp tissue). Haemostasis is achieved with bipolar diathermy and topical vasoconstrictors; absorbable haemostatic material or non-absorbable dissolvable packing is placed in the nasal cavity.

Most patients are discharged the same day or the following morning. No nasal packing is placed in most contemporary FESS cases.

Procedure Steps

1. CT paranasal sinuses; nasal endoscopy; allergy skin testing; medical therapy failure documented
2. General anaesthesia; topical decongestion; 4K endoscope system
3. Uncinectomy; maxillary antrostomy; anterior ethmoidectomy
4. Frontal sinusotomy (if frontal disease); posterior ethmoidectomy; sphenoidotomy
5. Nasal polyp debridement with microdebrider; haemostasis
6. Absorbable packing placed; discharge same day or next morning
7. Nasal rinses and topical steroids prescribed; endoscopy review at 4 weeks

FESS in the USA costs $6,000–$15,000. In India, bilateral FESS including all endoscopic sinuses costs $1,800–$4,000. The 4K endoscope system, powered microdebrider, and computer-aided navigation (used for complex revision or extended FESS) are available at India's leading ENT centres.

Recovery & Follow-up

Recovery from FESS is 1–2 weeks for return to normal activities. The first 5–7 days involve nasal congestion, blood-stained mucus, and reduced sense of smell as the operated sinuses heal. Saline rinses 3 times daily are critical to removing the post-operative crust and promoting healing. The operated sinuses continue to improve for 3–6 months as mucosal regeneration and reciliation occur. Post-operative endoscopy at 4 weeks allows the surgeon to clean any residual crust and assess healing.

Recovery Tips

• Perform nasal saline rinses 3 times daily for 6 weeks — this is the most important post-operative measure for good healing
• Use the topical nasal steroid spray from day 5 — this is the long-term measure that maintains the opened sinuses
• Avoid nose-blowing for 10 days — sniff gently instead
• Avoid air travel for 1 week — changes in cabin pressure affect the healing sinuses
• Attend the 4-week endoscopy review — crusts must be removed from the healing sinuses by the surgeon to prevent synechiae (adhesion formation)

Risks & Complications

FESS risks include: bleeding (epistaxis — usually minor, managed with topical vasoconstrictors; severe epistaxis from anterior ethmoid or sphenopalatine artery injury is rare); orbital injury (medial orbital wall perforation causing orbital haematoma or extraocular muscle injury — 0.04–0.1%); CSF leak (breach of the anterior skull base — 0.1–0.2%; managed with fascial repair); optic nerve injury (from sphenoid surgery proximity — very rare); intracranial complications (meningitis, intracranial abscess from skull base breach — extremely rare); and anosmia (rare — from surgical trauma to the olfactory epithelium). These complications are minimised by careful CT review, CT-guided navigation for complex cases, and experienced surgeon technique.

Why GAF Healthcare

GAF Healthcare connects patients with India's ENT surgeons who use 4K endoscope systems and intraoperative image-guided navigation for complex or revision FESS. CT sinus imaging is reviewed before travel; the surgical extent (which sinuses, bilateral or unilateral, with or without navigation) is planned and confirmed before the patient arrives. Post-operative nasal rinse and topical steroid protocols are provided in written form for continuation at home.

Frequently Asked Questions

Will my nasal polyps come back after FESS?

FESS removes existing polyps and opens the sinus drainage pathways, but it does not cure the underlying eosinophilic airway inflammation that drives polyp formation. Without ongoing medical management, polyps recur in 30–40% of patients within 5 years. With consistent post-operative topical corticosteroid spray, saline rinses, and management of underlying allergy and asthma, the recurrence rate is significantly reduced. Biological treatments (dupilumab, mepolizumab) are now available for severe, recurrent CRSwNP — these dramatically reduce polyp recurrence and are available at India's specialist allergy and immunology centres.

How quickly will my sense of smell improve after FESS?

Many patients notice some improvement in smell (anosmia or hyposmia from nasal polyps or mucosal inflammation) within days of surgery. Full olfactory recovery takes weeks to months as the olfactory cleft (the area at the top of the nasal cavity where the smell receptors are) becomes less obstructed and the mucosal inflammation resolves. In severe CRSwNP with longstanding complete anosmia, the olfactory nerves may have undergone secondary degeneration — in these cases, improvement may be partial. A short course of oral corticosteroids after FESS significantly improves smell recovery.

How long does FESS take?

Bilateral FESS involving all four sinus groups (maxillary, ethmoid, frontal, sphenoid) typically takes 60–90 minutes. Limited unilateral FESS targeting only the maxillary and anterior ethmoid sinuses takes 30–45 minutes. Complex revision FESS (re-operating after previous sinus surgery where normal anatomical landmarks are lost) takes 90–120 minutes. Most patients are discharged from hospital 2–4 hours after recovery from anaesthesia on the same day.
