The classifications are:

  • Trigeminal neuralgia, type 1, (TN1): facial pain of spontaneous onset with greater than 50% limited to the duration of an episode of pain (temporary pain).
  • Trigeminal neuralgia, type 2, (TN2): facial pain of spontaneous onset with greater than 50% as a constant pain.
  • Trigeminal neuropathic pain, (TNP): facial pain resulting from unintentional injury to the trigeminal system from facial trauma, oral surgery, ear, nose and throat (ENT) surgery, root injury from posterior fossa or skull base surgery, stroke, etc.
  • Trigeminal deafferentation pain, (TDP): facial pain in a region of trigeminal numbness resulting from intentional injury to the trigeminal system from neurectomy, gangliolysis, rhizotomy, nucleotomy, tractotomy, or other denervating procedures.
  • Symptomatic trigeminal neuralgia, (STN): pain resulting from multiple sclerosis.
  • Postherpetic neuralgia, (PHN): pain resulting from trigeminal Herpes zoster outbreak.
  • Atypical facial pain, (AFP): pain predominantly having a psychological rather than a physiological origin.
