Chronic neuropathic orofacial pain (Q47466): Difference between revisions

Chronic neuropathic orofacial pain is chronic pain in the orofacial region that is caused by a lesion or disease of the peripheral somatosensory nervous system. It occurs for two hours or more per day (or several shorter attacks per day occur) on at least 50% of the days during at least three months. The diagnosis of chronic neuropathic orofacial pain requires a history of peripheral nervous system injury or disease and a neuroanatomically plausible distribution of the pain. Negative and positive sensory symptoms or signs must be compatible with the innervation territory of the affected nervous structure.
