We are committed to providing thorough and evidence-based ENT care tailored to each patient’s needs. Our team manages a wide range of sinus, throat, skull base, and general ENT conditions with a structured and precise approach to diagnosis and treatment.
When surgery is necessary, we emphasise minimally invasive techniques to reduce recovery time and enhance patient comfort. With a strong focus on patient well-being, we strive to deliver
effective and thoughtful care at every stage of treatment.
Your initial consultation will include a detailed discussion of your symptoms, medical history, and a physical examination.
Nasal endoscopy may be performed if needed. This allows for a clearer understanding of your condition and the appropriate next steps.
We manage a range of nasal, sinus and throat-related conditions, including chronic sinusitis, nasal obstruction, deviated septum, nasal polyps, skull base disorders, and throat infections such as tonsillitis.
Certain nasal, sinus, or throat issues can be managed with medication or less invasive treatments.
Surgery may be recommended if non-surgical options are not effective or if the condition is more complex. Your specialist will advise based on your diagnosis.
Sinus surgery is generally well-tolerated. With modern anaesthesia and pain management protocols, most patients experience minimal discomfort during the procedure.
Post-operative discomfort is usually mild and can be managed with prescribed medication. Swelling of the nose or face is uncommon, and most procedures do not involve external cuts or visible scarring.
Some people believe that sinus surgery offers only short-term relief. However, for appropriately selected patients, the results are typically long-lasting.
The procedure addresses underlying structural issues, which helps reduce symptom recurrence—especially when supported by proper care and follow-up.
Consultation fees start from $200 SGD (excluding GST). Procedures with an applicable surgical code may be eligible for insurance and MediSave coverage.
