Trigeminal neuralgia it's a kind of chronic pain Disorder, which affects the trigeminal nerve. There are mainly two types:

Typical trigeminal neuralgia and atypical trigeminal neuralgia.

The typical form or this disorder results in certain episodes of severe, sudden, shock-like crises. pain on one side of the face, which lasts from a few seconds to a few minutes.

The symptoms

Trigeminal neuralgia may have symptoms that include one or more of patterns such as the following:

Some episodes of acute and intense pain that may seem electric. shock.

A person may encounter spontaneous pain attacks or even attacks that can be triggered by certain things such as touching the face, chewing, talking or even while brushing the teeth.


When trigeminal neuralgia occurs, trigeminal nerve function is interrupted. The problem occurs through a contact between an artery or a vein and the trigeminal nerve at the base of the brain. This contact exerts pressure on the nerve, which causes its malfunction.

While shaving When someone touches your face. When a person is eating something While brushing the teeth Smiling Washing the face.

What is radiofrequency ablation for trigeminal neuralgia?

Radiofrequency ablation or RFA is a technique through which surgery, which helps direct high frequency heat to specific areas of the body, such as tumors and tissues. When a person suffers from chronic pain, it means that the high frequency heat is focusing on the nerves.

A person suffering from trigeminal neuralgia would have his doctor, who is a neurosurgeon, uses radiofrequency ablation to hit the trigeminal nerve, thus destroying the nerve's ability to transmit pain signals to the brain.

The medication is the first line of treatment for trigeminal neuralgia by a neurosurgeon, to see how the patient reacts. If that person suffers from severe pain in the face and shows no improvement with the medication, then the doctor may recommend that you undergo radiofrequency ablation surgery.

How is the procedure carried out?

During radiofrequency ablation for trigeminal neuralgia, people remain awake and asleep at different times. The process includes:

When the patient is asleep under the influence of the general. anesthesiaA neurosurgeon would carefully place a needle through the corner of the mouth to reach the trigeminal nerve, which is located at the base of the skull. Then, once the X-rays confirm that the needle is in place, the neurosurgeon would awaken the patient, stimulate the nerve and ask if he could feel the stimulation exactly where the pain is experienced. This particular step confirms that the doctor has hit the correct location. Once the patient goes back to sleep, the doctor uses radiofrequency heat to minimize injury to the nerve, enough to induce a numbness in the face along with shudderwell remove the pain.
