13.1.1.2 Classical trigeminal neuralgia with concomitant persistent facial pain

Previously used terms:
Atypical trigeminal neuralgia; trigeminal neuralgia type 2.

Description:
Trigeminal neuralgia with persistent background facial pain.

Diagnostic criteria:
A. Recurrent attacks of unilateral facial pain fulfilling criteria for 13.1.1 Classical trigeminal neuralgia
B. Persistent facial pain of moderate intensity in the affected area
C. Not better accounted for by another ICHD-3 diagnosis.

Comments:
13.1.1.2 Classical trigeminal neuralgia with concomitant persistent facial pain has been referred to as atypical trigeminal neuralgia or, recently, as trigeminal neuralgia type 2.

Central sensitization may account for the persistent facial pain. Neurovascular compression on MRI is less likely to be demonstrated. 13.1.1.2 Classical trigeminal neuralgia with concomitant persistent facial pain responds poorly to conservative treatment and to neurosurgical interventions. It is less likely to be triggered by innocuous stimuli.
