Updated: 11 Feb 2026 Reviewed by Dr Dennis Chua

Key takeaways

  • Endoscopic sinus surgery is a minimally invasive procedure used to improve sinus drainage and ventilation in patients with chronic or recurrent sinus conditions, typically when symptoms persist despite medical treatment.
  • The procedure uses a nasal endoscope to visualise and access sinus pathways through the nostrils, without external incisions, allowing targeted treatment of inflamed or obstructed sinus openings while preserving surrounding nasal structures.
  • Pre-operative assessment includes clinical evaluation and imaging to determine the extent and cause of sinus disease, ensuring accurate diagnosis and planning for the procedure.
  • Suitability for surgery depends on individual factors, such as symptom severity, response to medical therapy, and underlying sinus anatomy, and requires assessment by an ENT specialist.
  • Assessment by an ENT specialist is important to confirm the diagnosis, discuss management options, and determine if surgical intervention is appropriate.

Endoscopic sinus surgery is a minimally invasive procedure used to improve sinus drainage and ventilation in patients with chronic or recurrent sinus conditions. It is typically considered when symptoms such as nasal blockage, facial pressure, recurrent infections, or reduced sense of smell persist despite appropriate medical treatment.

The procedure involves the use of a nasal endoscope to visualise and access the sinus pathways through the nostrils, without external incisions. This allows targeted treatment of inflamed or obstructed sinus openings while preserving surrounding nasal structures. Pre-operative assessment usually includes clinical evaluation and imaging to determine the extent and cause of sinus disease.

Suitability for endoscopic sinus surgery depends on individual factors, including symptom severity, response to medical therapy, and underlying sinus anatomy. Assessment by an ENT specialist may be considered to confirm the diagnosis, discuss management options, and determine whether surgical intervention is appropriate.

It’s a persistent condition that requires medical attention. If you’ve tried various medications with little success, you might be wondering: is endoscopic sinus surgery the next step?

Let’s explore what this procedure involves, who it’s for, and how it can help you breathe freely again.

What Is Endoscopic Sinus Surgery?

Endoscopic sinus surgery, also known as functional endoscopic sinus surgery (FESS), is a minimally invasive procedure used to treat sinus-related issues, especially chronic sinusitis. Using an endoscope, which is a thin, flexible tube, an ENT specialist can access your sinus passages through your nostrils—no external incisions required.

This allows the doctor to remove obstructions such as nasal polyps, inflamed tissue, or thick mucus that’s been causing blockages, pain, or infections.

In Singapore, this procedure has become a preferred approach for patients who are exploring long-term relief with minimal recovery time.

Do You Need Sinus Surgery? Signs and Symptoms to Watch For

Sinusitis in Singapore is more common than most realise, partly due to the humid climate, which can foster the growth of allergens and bacteria. But climate alone isn’t always to blame.

Here are some signs that may indicate you’re a candidate for surgery:

  • Chronic nasal congestion lasting 12 weeks or more
  • Recurrent sinus infections
  • Structural issues, such as a deviated septum or turbinate hypertrophy (swollen turbinate tissue) 
  • Poor response to antibiotics or steroid sprays

Patients who have been relying on medication for months without significant improvement may benefit from surgical intervention. The objective of surgery is to improve sinus function, not just offer short-term relief. ENT specialists typically recommend imaging, such as a CT scan or nasal endoscopy, to confirm the source of the problem before recommending surgery.

Benefits of Endoscopic Sinus Surgery

Many patients delay surgery out of fear or uncertainty—but the benefits are often worth considering, especially when symptoms affect daily life.

Here’s what successful surgery can offer:

  • Long-term relief from sinus pressure and congestion
  • Fewer infections and less dependence on antibiotics
  • Improved breathing and sense of smell
  • Better sleep and overall well-being
  • Minimal scarring and downtime

While these outcomes are common, every case is unique—it’s best to consult your ENT doctor to understand the potential benefits and risks based on your individual condition. Book an appointment with Dr Dennis Chua to learn more.

“Patients often tell me they didn’t realise how much sinusitis was affecting their life until after they recovered from surgery,” Dr Chua shares. “It’s not just about the nose—it’s about energy levels, focus, even mood.”

What to Expect During a Sinus Surgery


If your ENT specialist recommends surgery, it’s natural to feel nervous. However, understanding the process can ease anxiety.

The procedure is typically performed under general anaesthesia and lasts between one to three hours. Most patients return home the same day. Precision imaging tools are used during surgery to navigate the nasal cavity and correct structural issues such as narrowed passages, swollen tissue, or polyps.

There are no external cuts, and bleeding is usually minimal. Patients are closely monitored after the procedure and receive detailed aftercare instructions to support healing.

Sinus Surgery: Recovery Tips and Aftercare

Recovery from endoscopic sinus surgery is generally smooth. Most people return to normal activities within a week, though complete healing may take several weeks to a few months.

To ensure a safe and effective recovery:

  • Rinse your nasal passages with saline regularly
  • Take any prescribed medications as instructed
  • Avoid strenuous activity for at least 10 to 14 days
  • Attend all follow-up appointments

Post-operative care plays a critical role in preventing complications and ensuring optimal healing. Proper aftercare speeds up recovery and reduces the likelihood of infection or recurrence.

Post-op care is just as important as the surgery itself,” Dr Chua advises. “Proper aftercare ensures a smooth recovery and reduces the chance of complications.

Risks and Considerations


While endoscopic sinus surgery is considered low-risk, as with any surgical procedure, complications are possible. These may include minor bleeding, infection, scarring, or, in rare cases, changes in vision or smell.

It is essential to discuss these risks in detail with your sinus specialist. A thorough consultation will help you understand both the benefits and potential drawbacks so you can make an informed decision.

Cost of Endoscopic Sinus Surgery in Singapore

The cost of endoscopic sinus surgery in Singapore varies based on the facility, surgeon’s expertise, and whether the procedure is done in a public hospital, private clinic, or day surgery centre.

Typical costs range from SGD 4,000-10,000, and this usually includes:

  • Specialist consultation
  • Diagnostic imaging (e.g. CT scans)
  • Surgery and anaesthesia
  • Post-operative care and reviews

Some or all of the cost may be claimable through Medisave or private health insurance. Clinics are generally transparent about pricing and can assist with understanding what is covered under local healthcare schemes.

Is Sinus Surgery the Right Choice for You?

Endoscopic sinus surgery isn’t for everyone, but for patients suffering from chronic sinusitis who’ve exhausted other treatment options, it can be an effective solution. A detailed assessment by a qualified ENT specialist will determine if surgery is appropriate based on your symptoms, medical history, and diagnostic results.

When carefully selected, surgical candidates often experience dramatic improvements in their breathing, energy levels, and overall comfort.

Frequently Asked Questions (FAQ)

Q: Is sinus surgery painful?

A: The procedure is done under anaesthesia so you won’t feel pain during surgery. Afterwards, most patients experience only mild discomfort.

Q: How long is the recovery period?

A: Most patients return to work within a week or two. Full recovery usually takes 3 to 4 weeks up to several months.

Q: Can sinusitis come back after surgery?

A: Yes, because surgery is only part of the overall treatment plan. Continued exposure to triggers and recurrence of polyps are some reasons why sinusitis may recur.

Q: Is there an age limit for this surgery?

A: There’s no specific age limit, though your ENT specialist will evaluate your overall health and sinus anatomy.

Q: Can I fly after sinus surgery?

A: Avoid flying for at least 2 weeks after surgery to minimise pressure-related discomfort.
