Trigeminal Neuralgia: Understanding and Effective Treatment Options

Experiencing sudden, sharp, electric or burning pain on one side of the face—particularly around the lips, eyes, or forehead—could be a sign of trigeminal neuralgia. This pain often intensifies during everyday activities like brushing teeth, eating, shaving, or even feeling a light breeze. The discomfort typically lasts for a few seconds to several minutes. If this sounds familiar, it's important to consider the possibility of trigeminal neuralgia.

How to Differentiate Trigeminal Neuralgia from Toothaches or Headaches

Trigeminal neuralgia is characterized by intense pain in areas of the face where the trigeminal nerve is located. It affects women slightly more than men, and while it most commonly appears after the age of 40, recent trends show it is increasingly affecting younger individuals. The pain typically occurs on one side of the face—most often the right—and is most commonly felt in the second and third branches of the nerve. Unlike toothaches or headaches, trigeminal neuralgia has a sudden onset and cessation. In the early stages, it often responds well to medications like carbamazepine.

Types of Trigeminal Neuralgia

There are two main types: primary and secondary trigeminal neuralgia. Primary trigeminal neuralgia, which accounts for over 90% of cases, is usually caused by blood vessels pressing on the trigeminal nerve root. Secondary trigeminal neuralgia, on the other hand, is caused by various organic lesions in the skull or elsewhere in the body. While the symptoms may appear similar to the primary type, secondary neuralgia often involves milder, continuous pain, reduced sensation in the trigeminal nerve area, and additional symptoms caused by damage to other cranial nerves. Known causes include multiple sclerosis, as well as primary or metastatic tumors.

Common Treatment Options for Trigeminal Neuralgia

There are several treatment methods available, including oral medications, radiofrequency ablation, balloon compression, and microvascular decompression. Each has its own advantages and is suitable for different patient profiles.

Medication Therapy

Carbamazepine is often the first-line treatment for patients in the early stages of trigeminal neuralgia. It works by inhibiting abnormal neural activity in the trigeminal nerve and reducing the excitability of nerve cells, which helps alleviate pain. However, while medication can provide temporary relief, symptoms often return, and long-term use may lead to side effects.

Minimally Invasive Procedures: Balloon Compression

Balloon compression is a minimally invasive procedure that involves placing a small balloon near the trigeminal nerve ganglion under imaging guidance. Once in position, the balloon is inflated with contrast dye to gently compress the nerve, disrupting the pain signals. This method is particularly suitable for elderly patients or those with poor general health who may not be candidates for general anesthesia or more invasive surgery.

Microvascular Decompression: A Long-Term Solution

Microvascular decompression is a surgical procedure performed behind the ear, where a small incision—typically around 4 cm—is made. Using a microscope, the surgeon locates the point where the trigeminal nerve exits the brainstem and identifies any blood vessels compressing the nerve. These vessels are then carefully moved away and separated using a small piece of Teflon padding. This technique does not damage the nerve root, ganglion, or its branches, allowing for the best possible preservation of facial sensation and function. Over 90% of patients report significant pain relief after the surgery, making it one of the most effective and widely accepted treatments for trigeminal neuralgia worldwide.

Choosing the Right Treatment for Lasting Relief

While there are many treatment options available for trigeminal neuralgia, not all offer long-term or curative results. For patients seeking a definitive solution, surgical options like microvascular decompression are considered the gold standard. If you or a loved one is struggling with facial pain, it's essential to consult with a specialist to determine the most appropriate course of action based on individual health and symptoms.
