Summary
Painful post-traumatic trigeminal neuropathy (PTTN) causes constant facial pain after nerve injury, unlike episodic trigeminal neuralgia. Diagnosis involves identifying trauma and clinical signs like swelling.
Area of Science:
- Neurology
- Oral Surgery
- Pain Medicine
Background:
- Painful post-traumatic trigeminal neuropathy (PTTN), also known as anesthesia dolorosa, is a neuropathic pain condition.
- PTTN is characterized by constant pain, differentiating it from the episodic pain of trigeminal neuralgia.
- It often arises after facial trauma or as a complication of trigeminal neuralgia treatments.
