Symptomatic trigeminal neuralgia
Description:Pain indistinguishable from Classical trigeminal neuralgia but caused by a demonstrable structural lesion other than vascular compression.
Diagnostic criteria:
- Paroxysmal attacks of pain lasting from a fraction of a second to 2 minutes, with or without persistence of aching between paroxysms, affecting one or more divisions of the trigeminal nerve and fulfilling criteria B and C.
- Pain has at least one of the following characteristics:
- intense, sharp, superficial or stabbing.
- precipitated from trigger areas or by trigger factors.
- Attacks are stereotyped in the individual patient.
- A causative lesion, other than vascular compression, has been demonstrated by special investigations and/or posterior fossa exploration.
There may be sensory impairment in the distribution of the appropriate trigeminal division. Unlike Classical trigeminal neuralgia, Symptomatic trigeminal neuralgia demonstrates no refractory period after a paroxysm.
