TRIGEMINAL NEURALGIA

---

Trigeminal neuralgia is a chronic pain condition that affects the trigeminal nerve, which carries sensation from your face to your brain. It is characterized by sudden, severe, and stabbing pain in the face. The pain can be triggered by everyday activities like brushing teeth, chewing, or even a light touch.

Trigeminal neuralgia is relatively rare, affecting about 12 out of 100,000 people per year. It is more common in women than in men and typically occurs in people over the age of 50. However, it can affect anyone at any age.

The main symptom of trigeminal neuralgia is intense facial pain. Other symptoms include:

• Sudden, severe, stabbing, or electric shock-like pain in the face
• Pain that lasts from a few seconds to several minutes
• Episodes of multiple attacks lasting days, weeks, months, or longer
• Pain that affects one side of the face
• Pain triggered by activities such as eating, talking, or touching the face
• Periods of remission where pain may reduce or disappear

Diagnosing trigeminal neuralgia involves several steps:

• Medical History and Physical Exam: Your doctor will review your symptoms and perform a physical examination, focusing on your neurological function.
• Neurological Examination: This helps to determine which branches of the trigeminal nerve are affected.
• Imaging Tests: MRI (Magnetic Resonance Imaging) is often used to rule out other causes of facial pain, such as a tumor or multiple sclerosis. It can also help to identify blood vessels pressing on the nerve.

Treatment for trigeminal neuralgia focuses on relieving pain. Options include:

• Medications: Drugs are often the first line of treatment and can include:
  • Anticonvulsants: Such as carbamazepine and oxcarbazepine, which help to reduce nerve pain.
  • Muscle Relaxants: Such as baclofen, which can be used in combination with anticonvulsants.
  • Tricyclic Antidepressants: Such as amitriptyline, which can also help manage pain.
• Surgery: Surgical options may be considered if medications are not effective or cause significant side effects:
  • Microvascular Decompression: This involves relocating or removing blood vessels that are compressing the trigeminal nerve, providing long-term relief.
  • Gamma Knife Radiosurgery: A non-invasive procedure that uses focused radiation to damage the trigeminal nerve and reduce pain.
  • Balloon Compression: A balloon is inserted and inflated to compress the nerve, damaging the pain fibers and reducing pain.
  • Glycerol Injection: Glycerol is injected into the trigeminal nerve root to damage the nerve and block pain signals.
  • Radiofrequency Rhizotomy: Uses heat to damage nerve fibers and block pain signals.

There are several surgical techniques for treating trigeminal neuralgia:

• Microvascular Decompression (MVD): The most common surgical treatment. It involves opening the skull to relocate or remove any blood vessels pressing on the trigeminal nerve.
• Gamma Knife Radiosurgery: A non-invasive procedure that focuses radiation precisely on the trigeminal nerve, damaging the nerve to reduce pain.
• Balloon Compression: A minimally invasive procedure where a balloon is inserted into the trigeminal nerve through the cheek and inflated to compress the nerve, reducing pain signals.
• Glycerol Injection: Involves injecting glycerol into the area where the trigeminal nerve exits the brainstem, which helps to reduce pain by damaging the nerve fibers.
• Radiofrequency Rhizotomy: Uses radiofrequency heat to selectively damage the nerve fibers that cause pain, providing relief.

Early diagnosis and appropriate treatment of trigeminal neuralgia can improve quality of life and reduce the impact of pain on daily activities. If you experience symptoms or have concerns about trigeminal neuralgia, it's important to consult your healthcare provider for a thorough evaluation.
