Chronic facial pain is often described by patients as one of the most physically and emotionally draining experiences a person can endure. Among the various causes of such distress, Trigeminal Neuralgia stands out for its intensity, frequently referred to in medical literature as the “suicide disease” due to the extreme nature of its symptoms. For many in Singapore, conventional medications eventually fail or cause intolerable side effects, leading them to seek more advanced interventions. One of the most effective and widely utilised modern treatments is Radiofrequency Ablation for facial pain treatment, a minimally invasive procedure that offers long-term relief without the need for major open-skull surgery.

Understanding Trigeminal Neuralgia: The “Electric Shock” Facial Pain
Trigeminal Neuralgia (TN) is a chronic pain condition that affects the trigeminal nerve, which is responsible for carrying sensation from your face to your brain. If you have TN, even mild stimulation of your face, such as brushing your teeth, applying makeup, or feeling a light breeze, may trigger a jolt of excruciating pain.
Common Symptoms
The symptoms of Trigeminal Neuralgia are distinct and often unmistakable:
- Episodes of severe, shooting, or jabbing pain that may feel like an electric shock.
- Spontaneous attacks of pain or attacks triggered by things such as touching the face, chewing, speaking, or brushing teeth.
- Bouts of pain lasting from a few seconds to several minutes.
- Pain that affects one side of the face at a time, though rarely it may affect both sides.
- Pain focused in one spot or spreading in a wider pattern (e.g., jaw, teeth, gums, lips, or less often the eye and forehead).
Causes And Triggers
The primary cause of Trigeminal Neuralgia is usually a blood vessel pressing on the trigeminal nerve at the base of the brain. This compression wears away the protective coating around the nerve (the myelin sheath), causing the nerve to malfunction and send “misfired” pain signals. Other causes include:
- Multiple Sclerosis: A disease that causes similar damage to the myelin sheath.
- Tumours: A growth pressing on the nerve.
- Physical Injury: Trauma to the face or surgical complications.
Diagnosis Of Facial Pain In Singapore
Diagnosing facial pain is a process of elimination. Because the pain can mimic severe toothaches, many patients in Singapore first visit a dentist and may even undergo unnecessary tooth extractions before the true cause is identified.
A pain specialist will typically conduct:
- A Neurological Examination: Touching and examining parts of your face to determine exactly where the pain is occurring and which branches of the trigeminal nerve are involved.
- Magnetic Resonance Imaging (MRI): A high-resolution scan of the brain to look for a blood vessel compressing the nerve or to rule out tumours and Multiple Sclerosis.
What Is Radiofrequency Ablation (RFA)?
When medications like Carbamazepine or Gabapentin are no longer effective or cause severe “brain fog” and dizziness, Radiofrequency Ablation for facial pain becomes a frontline option.
The Science Behind RFA
RFA is a “thermal lesioning” technique. It uses the heat generated from medium-frequency alternating current (radio waves) to selectively damage the specific part of the trigeminal nerve responsible for the pain. By creating a controlled “lesion” on the nerve, the procedure interrupts the transmission of pain signals to the brain, essentially “silencing” the overactive nerve.
What Does The Procedure Involve?
The procedure is performed as a day surgery and typically follows these steps:
- Sedation: The patient is given light “twilight” sedation to ensure comfort while remaining communicative.
- Needle Placement: Using X-ray or CT guidance, the specialist inserts a thin, specialised RF needle through the cheek and into an opening at the base of the skull (the foramen ovale) to reach the trigeminal ganglion.
- Testing: To ensure precision, a tiny electrical current is passed through the needle. The patient may feel a slight tingling in the area of their usual pain, confirming the needle is at the correct “branch” of the nerve.
- Ablation: Once the location is confirmed, the radiofrequency energy is applied for about 60 to 90 seconds to heat the nerve tissue.
The Advantages Of RFA For Patients
Radiofrequency Ablation is highly favoured in Singapore clinics for several reasons:
- Minimal Downtime: It is a “pinhole” procedure. Patients typically return home on the same day and resume light activities within 48 hours.
- High Success Rate: Significant pain relief is achieved in over 80% to 90% of patients immediately following the procedure.
- Safety: Unlike Microvascular Decompression (MVD), RFA does not require opening the skull (craniotomy), making it a safer choice for elderly patients or those with other medical conditions.
- Repeatability: If the nerve eventually heals and the pain returns (usually after 2 to 3 years), the procedure can be safely repeated.
Cost Of Radiofrequency Ablation For Facial Pain In Singapore
The cost of pain management in Singapore for advanced procedures like RFA depends heavily on the setting and the complexity of the case. In 2026, patients can expect the following estimated price ranges (MOH fee benchmark – TOSP Code SK701F):
| Expense Category | MOH Recommended Fee Benchmark |
| Professional Fee (Surgeon) | $1,400 – $2,400 |
| Inpatient Doctors’ Attendance Fees | $210 – $420 per day |
| Anaesthetist Fee | Not Available |
| Facility/OT Charges | Not Available |
As RFA is a surgical procedure, it is eligible for MediSave claims. Patients can typically use MediSave to offset approximately $1,500 to $2,500 of the bill. For those with an Integrated Shield Plan and a rider, the majority of the cost—including the expensive single-use RF needles—is usually covered, leaving the patient with a 5% co-payment.
Why Specialist Experience Matters
While the technology of Radiofrequency Ablation for facial pain is standardised, the “art” of the procedure lies in the needle placement and the temperature control. Pain management specialists with greater experience may be better placed to carry out these procedures with a higher degree of success.

Recovery And Expectations
Immediately after RFA, patients may feel a slight numbness in the treated area of the face. This is a sign that the nerve block has been successful. While the sharp “shocks” disappear instantly, there may be some mild soreness at the injection site on the cheek for a few days. Most patients report a dramatic improvement in their quality of life, finally being able to eat, talk, and wash their faces without fear of a sudden attack.
