Yes, Functional Endoscopic Sinus Surgery is highly effective for patients with chronic sinusitis who have not responded sufficiently to medical treatments. In the UK, this procedure is the standard surgical approach for opening the sinus drainage pathways and removing obstructions such as thickened tissue or nasal polyps. Unlike older surgical methods, FESS is designed to be as minimally invasive as possible, focusing only on the specific areas where the sinuses are blocked.
By restoring natural ventilation and drainage, FESS significantly reduces the frequency and severity of sinus infections. Most patients in the UK report a substantial improvement in their quality of life, including better breathing, reduced facial pain, and an improved sense of smell. The surgery is most effective when combined with ongoing medical management to control the underlying inflammation.

How FESS restores sinus function
The word functional in FESS is key because the surgery aims to restore the normal physiological function of the sinuses rather than just removing tissue. The sinuses are lined with cilia, which act like microscopic oars to move mucus toward the natural drainage ports. If these ports are blocked by inflammation or polyps, the mucus becomes trapped, leading to the pressure and infection characteristic of chronic sinusitis.
During the procedure, a UK specialist uses high definition cameras and precision instruments to:
- Remove obstructions: Clearing away polyps or swollen mucosa that block the openings.
- Widen drainage ports: Slightly enlarging the natural holes to prevent future blockages.
- Straighten the septum: If a deviated septum is contributing to the drainage issues.
- Clear infection: Removing stagnant mucus or fungal debris from the cavities.
Success rates and symptom relief
Clinical data in the UK shows that approximately 80 to 90 percent of patients experience significant relief from their symptoms after FESS. The most notable improvements are typically seen in nasal obstruction and facial pressure. While the sense of smell often improves, its recovery can be more variable depending on how much damage the chronic inflammation has caused to the olfactory nerves over time.
The UK surgical pathway and recovery
FESS is typically performed under general anaesthetic as a day case procedure in UK hospitals. Because the surgery is performed entirely through the nostrils, there are no external cuts or bruising.
The recovery timeline generally follows this pattern:
- Days 1 to 3: Expect some nasal congestion and minor blood stained discharge.
- Week 1: Most patients use saline rinses frequently to clear surgical crusting.
- Week 2: Most people can return to work and light activities.
- Month 1: A follow up appointment with the specialist ensures the sinuses are healing correctly.
Comparison: FESS vs Traditional Sinus Surgery
| Feature | Functional Endoscopic Surgery (FESS) | Traditional Open Surgery |
| Incisions | None internal through nostrils | Often required under the lip or on the face |
| Precision | High via HD endoscopic cameras | Lower based on direct line of sight |
| Tissue Impact | Preserves healthy mucosa | More aggressive tissue removal |
| Recovery Time | 1 to 2 weeks | 3 to 4 weeks |
| Hospital Stay | Usually a day case | Often requires overnight stay |
| UK Standard | Current gold standard | Rarely used for routine sinusitis |
To Summarise
Functional Endoscopic Sinus Surgery is a highly effective and precise method for treating chronic sinusitis in the UK. By focusing on restoring the natural drainage pathways of the nose, it provides long term relief for the majority of patients who have struggled with persistent congestion and facial pain. While the surgery provides the physical opening needed for healthy sinuses, the best long term results are achieved when patients remain consistent with their post operative medical care. FESS offers a proven pathway to clearer breathing and a significant reduction in the burden of chronic sinus disease.
If you have been suffering from sinus symptoms for more than twelve weeks despite using medical treatments, book an appointment with your GP to discuss a referral for a surgical consultation.
Will I have black eyes after FESS?
No. Because the surgery is performed entirely inside the nose with no external incisions, bruising or black eyes are extremely rare.
How long do the results of FESS last?
For many, the results are long lasting. However, chronic sinusitis is an inflammatory condition. If you have underlying issues like severe allergies or asthma, you must continue using nasal steroids to prevent the inflammation from returning.
Is FESS painful?
Most patients describe the feeling after surgery as a heavy cold or sinus pressure rather than sharp pain. UK hospitals provide effective pain relief, and most people only need paracetamol for a few days.
Can FESS be performed more than once?
Yes. In some complex cases, particularly those involving aggressive nasal polyps, a second procedure may be necessary years later. However, modern techniques and biologics are reducing the need for repeat surgeries.
When can I fly after sinus surgery?
In the UK, specialists usually advise waiting at least two weeks before flying to avoid the risk of pain or bleeding caused by air pressure changes in the newly opened sinuses.
Will I have packing in my nose after the operation?
Most modern UK surgeons avoid using traditional nasal packing. If necessary, they may use dissolvable materials that do not need to be painfully removed after the operation.
