Trigeminal neuropathy is caused by injury to one or more branches of the trigeminal nerve and may result in numbness, tingling, altered sensation, or persistent neuropathic facial pain.
Unlike classical trigeminal neuralgia, trigeminal neuropathy is characterized by objective sensory disturbances and usually has an identifiable underlying cause, such as trauma, dental procedures, tumors, infections, autoimmune disease, or multiple sclerosis.
Diagnosis combines neurological examination with MRI and, when appropriate, neurophysiological testing. Treatment depends on the underlying cause and often includes neuropathic pain medication, rehabilitation, and multidisciplinary care.
