What sinus surgery is (and what it’s meant to do)
If you’ve lived with a blocked nose, facial pressure, post-nasal drip, or endless sinus infections for months (or even years), you’ll know how exhausting chronic sinusitis can be. When medications, nasal sprays and antibiotics no longer seem to help, many patients in Singapore start hearing about endoscopic sinus surgery as the “next step”.
But what does it actually involve? How does a sinus surgeon perform the procedure? And how do you know if you’re a suitable candidate for sinus surgery in the first place?
This guide breaks it all down in clear, patient-friendly language – so you can better understand what your specialist may be recommending, and walk into your consultation feeling informed rather than anxious.
Understanding Chronic Sinusitis: When the Sinuses Won’t Settle
Your sinuses are air-filled spaces around the nose and eyes. They are lined with mucosa – a thin, moist layer that produces mucus to trap dust, allergens and germs. Normally, this mucus drains smoothly into the nose through small openings.
With chronic sinusitis, this system stops working properly because of:
- Long-term inflammation and swelling of the sinus lining
- Blocked or narrowed drainage pathways
- Structural issues such as a deviated septum
- Nasal polyps (soft, non-cancerous growths)
- Ongoing allergy or irritant exposure
Instead of draining away, mucus becomes trapped. This leads to:
- Stuffy or blocked nose
- Facial pressure or chronic sinus pain
- Reduced sense of smell or taste
- Thick nasal discharge or post-nasal drip
- Fatigue, “heavy head”, poor sleep
If these symptoms persist for more than 12 weeks and do not respond well to medical treatment, your sinus doctor may diagnose chronic rhinosinusitis and start talking about more advanced options – including surgery.
First-Line Treatment: Not Every Sinus Patient Needs Surgery
Before discussing sinus surgery, it’s important to know that not every blocked nose or sinus infection needs an operation. In fact, many patients improve with careful medical management guided by an ENT doctor.
Common non-surgical treatments include:
- Nasal steroid sprays to reduce inflammation
- Saline rinses or sprays to wash out mucus and irritants
- Short courses of antibiotics for bacterial infections
- Oral steroids in selected cases, especially with nasal polyps
- Allergy control, such as antihistamines or avoiding triggers
- Lifestyle adjustments – staying hydrated, managing air-conditioning exposure, smoking cessation, etc.
Your sinus specialist will usually recommend a structured period of medical therapy first. Surgery is usually considered when:
- Symptoms remain moderate to severe despite adequate treatment
- CT scans show significant disease or blockage in the sinuses
- There are recurrent acute sinus infections requiring repeated antibiotics
- There are nasal polyps or structural issues that clearly obstruct drainage
If you’ve reached this point, your ENT may explain how endoscopic sinus surgery can help.
What Is Endoscopic Sinus Surgery?
Endoscopic sinus surgery (often called Functional Endoscopic Sinus Surgery or FESS) is a minimally invasive procedure performed through the nostrils. There are no external cuts or scars.
Using a thin telescope called an endoscope, your sinus surgeon:
- Views the nasal passages and sinus openings on a high-definition screen
- Uses fine instruments to:
- Remove diseased tissue and polyps
- Widen narrowed drainage pathways
- Clear blocked sinuses so mucus can drain normally again
- Remove diseased tissue and polyps
The goal of surgery is not to “cure” sinusitis overnight, but to:
- Restore better ventilation and drainage of the sinuses
- Make your nose and sinuses more responsive to ongoing medical treatment
- Reduce the frequency and severity of infections and flare-ups
In other words, the procedure is part of a long-term management plan rather than a magic switch – but for many patients, it’s a genuine turning point in their sinus journey.
How Your Sinus Specialist in Singapore Decides if You’re a Candidate
Before recommending surgery, your ENT specialist will usually go through a detailed assessment, which may include:
1. Thorough History and Examination
You’ll discuss:
- How long you’ve had symptoms
- How often you get sinus infections
- What medications you’ve tried and for how long
- How sinusitis is affecting your sleep, work, and daily life
Your specialist will examine your nose using a headlight or small instrument, and often perform nasal endoscopy in clinic – a quick scope using a thin flexible or rigid camera to look inside the nose and sinus openings.
2. Imaging Studies (Usually CT Scan)
A CT scan of the sinuses is commonly ordered to:
- See which sinuses are affected
- Assess the degree of blockage or mucosal disease
- Identify anatomical variations (e.g. deviated septum, narrow drainage channels)
- Help plan surgery safely around important structures like the eyes and skull base
3. Trial of Medical Therapy
Most ENT surgeons prefer that patients have undergone a proper trial of medication – including nasal steroids, saline rinses, and other necessary drugs – before operating. This ensures that surgery is considered for truly stubborn sinusitis rather than conditions that could have improved with simpler treatments.
What Happens on the Day of Sinus Surgery?
Every clinic and hospital has slightly different routines, but a typical journey for endoscopic sinus surgery might look like this:
Pre-Operative Preparation
You’ll have:
- A pre-operative assessment and consent discussion with your sinus surgeon
- Possible blood tests or other investigations, depending on your health
- Instructions on when to stop eating and drinking before surgery
- Advice on which regular medications to continue or pause
If you are on blood-thinning medications, your surgeon and anaesthetist will advise on how to manage these safely.
Anaesthesia
Endoscopic sinus surgery is usually performed under general anaesthesia, meaning you are asleep and pain-free during the procedure. An anaesthetist monitors you closely throughout.
The Operation Itself
During sinus surgery, your surgeon:
- Inserts the endoscope and instruments through the nostrils
- Carefully removes:
- Thickened, diseased mucosa where appropriate
- Polyps that are blocking airflow
- Bony partitions where necessary to widen drainage pathways
- Thickened, diseased mucosa where appropriate
- Opens up the natural drainage channels of the affected sinuses
In some cases, the surgeon may also correct a deviated nasal septum (septoplasty) or reduce enlarged turbinates (structures inside the nose) in the same sitting to improve airflow.
The length of surgery depends on:
- How many sinuses are involved
- Whether there are polyps
- Whether other procedures are done at the same time
After Sinus Surgery: Recovery and Results
Many patients are understandably nervous about what happens after surgery. While experiences vary, here’s a general overview.
Immediately After Surgery
- You’ll wake up in the recovery area with monitoring.
- There may be some congestion, mild bleeding, or pressure in the nose and face.
- Some patients have nasal packing or soft dressings which the surgeon will remove at the appropriate time.
You may go home the same day or stay overnight, depending on the complexity of surgery and your overall health.
First 1–2 Weeks
It’s common to experience:
- Nasal congestion and blockage (similar to a bad cold)
- Mild to moderate facial pressure
- Blood-stained mucus or discharge initially
Your specialist will usually prescribe:
- Pain relief medication
- Nasal sprays or saline rinses (once it’s safe to start)
- Sometimes a short course of antibiotics or oral steroids
You’ll be advised to:
- Avoid strenuous activity, heavy lifting, and nose-blowing initially
- Sleep with your head slightly elevated to reduce swelling
- Keep follow-up appointments for nasal cleaning and endoscopic checks
Follow-Up Care
Post-operative care is crucial to long-term success. Your surgeon may:
- Gently clear crusts and secretions from inside the nose during follow-ups
- Adjust your nasal sprays, rinses, or other medications
- Monitor healing and ensure the openings created during surgery remain patent
In chronic sinusitis, surgery and ongoing medical treatment work hand in hand. Many patients need continued use of nasal steroid sprays, saline rinses, and allergy management to keep inflammation in check even after surgery.
Long-Term Outcomes
Most appropriately selected patients experience:
- Reduced frequency and severity of sinus infections
- Improvement in nasal breathing
- Less facial pressure and “heavy head” feeling
- Better sleep and overall quality of life
It’s important to remember that, especially in conditions driven by allergy or other systemic issues, surgery improves anatomy and drainage – but ongoing care with your surgeon remains part of long-term management.
Risks and Complications: What Your Sinus Surgeon Will Explain
No surgery is risk-free, and your surgeon will discuss potential complications with you beforehand. While serious complications are uncommon in experienced hands, they can include:
- Significant bleeding
- Infection
- Scar tissue or adhesions inside the nose
- Persistence or recurrence of sinus symptoms
- Very rarely, complications involving the eye or skull base
Your surgeon uses pre-operative imaging, careful planning, and modern instruments to minimise these risks. Don’t be afraid to ask questions about anything you don’t understand – a good ENT surgeon will always take time to clarify.
Is Endoscopic Sinus Surgery Right for You?
If you’re wondering whether to proceed with sinus surgery, these questions can help frame your discussion with your ENT doctor:
- Have I had symptoms for months or years despite proper medical treatment?
- Have I completed courses of nasal steroids, rinses, and other medications as advised?
- Do CT scans show significant sinus disease or obstruction?
- Are my sinus problems affecting sleep, work, or daily functioning?
- Do I understand the goals, benefits, and limitations of surgery?
- Am I prepared to commit to post-operative care and long-term medical management?
Your doctor will bring their clinical expertise, scan findings, and experience into the conversation, helping you decide if surgery is the next logical step – or if further medical optimisation is still worthwhile.
Making the Most of Your Consultation with a Sinus Specialist
To get a clear, personalised answer on whether you should see a sinus surgeon for possible surgery, consider:
- Bringing a list of your medications and previous antibiotics
- Noting how many sinus infections you’ve had in the last year
- Describing how sinusitis affects your sleep, energy, work and mood
- Listing questions about the procedure, recovery, and long-term care
A good consultation is a two-way conversation. Your ENT doctor’s role is not only to operate, but to help you understand your condition and choose the safest, most effective treatment path for your lifestyle and goals.
Final Thoughts
Endoscopic sinus surgery has transformed how sinus specialists manage stubborn sinusitis. Instead of large external incisions, today’s surgeon works through the nostrils with fine endoscopic instruments, aiming to restore your sinuses to a healthier, better-draining state.
Surgery is rarely the first step – but when medication alone is no longer enough, it can be a powerful tool to reduce infections, ease congestion, and improve your daily comfort.
If you’ve been living with chronic sinus problems and are wondering about your options, consider booking a detailed assessment with a sinus specialist. With the right information, you and your doctor can decide together whether endoscopic sinus surgery is the step that finally helps you breathe – and live – a little easier again.
