Trigeminial Neuralgia

Forms of Trigeminal Neuralgia

Trigeminal neuralgia is categorized into the following seven forms:

1. Typical Trigeminal Neuralgia: This is the most common form and was previously termed as classical, idiopathic and essential trigeminal neuralgia.

2. Atypical Trigeminal Neuralgia: This is characterized by severe, unilateral, prominent constant and burning pain over the typical TN symptoms.

3. Pre-Trigeminal Neuralgia: A few days or years before the first attack of trigeminal neuralgia patients experience odd sensations in trigeminal distributions that have the potential to be affected by trigeminal neuralgia; these odd sensations/pain (toothache) may be symptoms of pre-trigeminal neuralgia.

4. Multiple Sclerosis-related Trigeminal Neuralgia: The symptoms and characteristics of multiple sclerosis related trigeminal neuralgia are similar to those of typical trigeminal neuralgia.

5. Secondary or Tumor related Trigeminal Neuralgia: Trigeminal neuralgia caused by a tumor is called secondary trigeminal neuralgia.

6. Trigeminal Neuropathy or Post-Traumatic Trigeminal Neuralgia: Injury to the trigeminal nerve caused by cranio-facial trauma (for example a car accident), dental trauma, sinus trauma (such as after Caldwell Luc procedures), may lead to a painful condition called trigeminal neuropathy or post-traumatic trigeminal neuralgia.

7. “Failed” Trigeminal Neuralgia: When medication or surgical interventions cannot effectively control trigeminal neuralgia, the condition is termed “failed” trigeminal neuralgia (5).
