Sinusitis Treatment by an ENT Sinus Specialist in Singapore
Sinusitis is a common ear, nose and throat (ENT) condition that may cause persistent nasal blockage, facial pressure, postnasal drip, and recurrent sinus infections. These symptoms can affect breathing comfort, sleep quality, and day-to-day functioning.
At our ENT clinic, sinusitis is assessed by Dr Leslie Koh, a sinus specialist in Singapore. Evaluation focuses on identifying underlying causes such as infection, allergies, or structural blockage, followed by a structured treatment plan that may include medication, monitoring, or surgical intervention where clinically appropriate.
What is Sinusitis?
Sinusitis refers to inflammation of the lining of the sinuses, which are air-filled spaces located behind the forehead, cheeks, and eyes. When the sinus openings become blocked, mucus can accumulate, creating an environment where infection or ongoing inflammation may occur.
Acute Sinusitis
Acute sinusitis typically lasts less than 4 weeks and is often associated with viral upper respiratory infections such as the common cold.
Chronic Sinusitis
Chronic sinusitis persists for more than 12 weeks despite treatment and may involve ongoing inflammation, structural obstruction, or recurrent infections.
In Singapore, sinusitis is commonly seen due to environmental allergens, humidity, and lifestyle factors that may contribute to nasal inflammation.
Symptoms of Sinusitis
Sinusitis symptoms may vary depending on severity and underlying cause.
Nasal Symptoms
-Persistent nasal blockage or congestion
-Thick nasal discharge
-Postnasal drip
Facial and Head Symptoms
– Facial pressure (cheeks, forehead, around the eyes)
– Headache, especially when bending forward
– Upper tooth discomfort
Other Symptoms
– Reduced sense of smell or taste
– Fatigue or reduced energy
– Sleep disturbance
Recognising these symptoms early may help guide appropriate evaluation and management.
What Causes Sinusitis in Singapore
Viral or Bacterial Infection After Flu or Cold
Sinusitis often develops when viral or bacterial infections following a common cold cause sinus lining inflammation and mucus buildup.
Untreated Allergic Rhinitis (Nose Allergy)
Ongoing nasal allergies can block sinus openings and trap mucus, increasing the likelihood of infection or chronic inflammation.
Structural Issues Such as Deviated Septum or Nasal Polyps
Anatomic irregularities can obstruct sinus drainage and predispose individuals to recurrent sinusitis.
Environmental Factors (Humidity, Air-Conditioning, Pollution)
Singapore’s humid climate, combined with prolonged air-conditioning exposure or air pollution, may worsen sinus symptoms in susceptible individuals.
Smoking Exposure
Tobacco smoke irritates the nasal passages, impairing the natural clearance of mucus and heightening infection risk.
Individuals with allergic rhinitis, asthma, or immunocompromised conditions are at higher risk of developing sinusitis and may benefit from early evaluation by a sinus doctor in Singapore.
When to See a Sinus Specialist in Singapore?
Below are situations where arranging a consultation with a sinus specialist in Singapore may be useful:
Symptoms Lasting Longer Than 10 Days
Persistent symptoms beyond the usual duration of a cold may signal ongoing sinus inflammation or infection.
Limited Response to Over-the-Counter Remedies
If sprays, decongestants, or antihistamines offer little relief, further assessment may help determine the underlying cause.
Frequent or Recurrent Sinus Infections
Repeated episodes may indicate structural narrowing, allergies, or chronic inflammation that require tailored management.
Significant Facial Discomfort or Pressure
Persistent pain or a sense of heaviness around the face may reflect blocked sinus drainage pathways.
Difficulty Breathing Through the Nose
Ongoing nasal blockage, especially when affecting sleep or day-to-day comfort, may suggest the need for specialist evaluation.
Subtle or Less Recognised Sinus-Related Symptoms
Symptoms such as postnasal drip, bad breath, ear pressure, or toothaches may be linked to sinus issues even in the absence of obvious congestion.
These signs may indicate conditions such as nasal polyps, a deviated septum, chronic inflammation, or unresolved infection.
How a Sinus Specialist Diagnoses Sinusitis
-
-
Clinical History and Physical Examination
The doctor reviews the duration of symptoms, possible triggers, and medical history, followed by inspection of the nasal cavity. -
Nasal Endoscopy (Tiny Camera Inspection)
A nasal endoscopy uses a fine flexible scope to visualise the nasal passages, sinus openings, and mucosal condition in real time. -
CT Scan to Assess Sinus Blockage
Imaging, such as a CT scan, provides detailed information on sinus structure, obstruction, or anatomical variations that may require further treatment. -
Allergy Testing for Chronic or Recurrent Sinusitis
If recurrent symptoms are suspected to be allergy-related, tests such as a skin prick or IgE blood test may be performed to identify potential allergens.

What are the Treatment Options for Sinusitis in Singapore
Medical Management
We understand that sinusitis can be extremely frustrating. After properly diagnosing your condition, we may initially recommend various non-surgical treatment methods, these include:
Antibiotics for bacterial sinusitis
Intranasal steroids
Intranasal antihistamines / decongestants
Oral antihistamines / decongestants
In more severe cases of sinus infection, or when non-surgical treatment methods have proven unsuccessful, our doctors may recommend:
- Sinus surgery
- Long-term intranasal steroids
- Biologic treatments for patients with nasal polyps
Nasal Care and Lifestyle Adjustments
- Saline nasal irrigation
- Allergen control
- Avoidance of environmental triggers
Monitoring and Follow-Up
Some cases improve with time and regular review, especially when symptoms are mild or resolving.
Treatment plans are tailored to each individual based on clinical findings.
Sinus Surgeon in Singapore: When Is Surgery Considered?
Surgical treatment may be considered when:
- Symptoms persist despite medical therapy
- Chronic sinusitis affects daily life
- Structural blockage prevents proper drainage
- Recurrent infections continue despite treatment
Functional Endoscopic Sinus Surgery (FESS)
Functional Endoscopic Sinus Surgery (FESS) is a minimally invasive procedure performed through the nostrils using specialised instruments.
The procedure aims to:
- Improve sinus drainage
- Remove blockages such as polyps
- Restore airflow and ventilation
FESS does not involve external incisions and is commonly considered when non-surgical treatment has not been effective.
Recovery and post-operative care are discussed in detail during consultation to support healing and long-term outcomes.

FAQs about Sinusitis in Singapore
1. Is sinusitis contagious?
Sinusitis itself is not contagious, but the viral infections that may cause it can be.
2. Can sinusitis go away without antibiotics?
Yes. Many cases of viral sinusitis resolve without antibiotics. Medication is usually prescribed if a bacterial infection is suspected.
3. Does sinus surgery fix a deviated septum?
Yes, frequently. While FESS (Sinus Surgery) clears drainage pathways, a septoplasty straightens the midline partition. Surgeons often perform them together because a deviated septum can physically block access to the sinuses. Combining them improves both your breathing and sinus drainage in one recovery period.
4. What happens during a sinus consultation?
A consultation includes a review of symptoms, a physical examination, and, if needed, further diagnostic testing to assess the sinuses.
5. How Can I Prevent Sinus Infections?
Regular nasal hygiene, management of allergies, and avoiding prolonged exposure to pollutants or cigarette smoke may reduce recurrence. Seeking early evaluation for nasal blockage or allergies can also prevent chronic issues.
6. What Is the Best Doctor to See for Sinus Issues?
Patients experiencing persistent or recurrent sinus problems should consult an ENT specialist doctor who can perform a detailed assessment, diagnosis, and treatment.
7. Can sinus surgery affect my sense of smell?
- Temporary Loss (Common): Expect a reduced sense of smell for 2-4 weeks due to swelling, crusting, or nasal packing.
- Permanent Improvement (Likely): If your loss of smell was caused by polyps or blockage, surgery often restores it by allowing air to reach the olfactory nerves.
- Permanent Damage (Rare): Total loss of smell (anosmia) is a rare risk (<1%) as surgeons use high-definition endoscopes to avoid the delicate nerves at the roof of the nasal cavity.
8. How much does sinus surgery cost in a private hospital?
Surgeon/Anaesthetist: Estimated Private Cost is $9,000 – $15,000, while the Estimated Public Subsidised Cost is $1,200 – $2,500
Hospital/Facility: Estimated Private Cost is $11,000 – $20,000, while the Estimated Public Subsidised Cost is $1,300 – $2,500
MediSave: Usually covers $2,150 – $4,850, depending on complexity.
Insurance: Most Integrated Shield Plans cover this if medical necessity is proven.
