Mimics of TN

Although all cases of trigeminal neuralgia are caused by irritation of the trigeminal nerve, not all trigeminal nerve irritations result in trigeminal neuralgia. Other possible diagnoses include:

  • Post-Herpetic Neuralgia (herpes zoster, shingles)
  • Pain after dental procedures with the development of a focal neuroma
  • Temporal tendinitis
  • Irritation of the styomandibular ligament (Ernest syndrome)
  • Focal nerve irritation/neuralgia from sinus disease or other causes (infraorbital neuralgia, Sluder’s neuralgia, anterior ethmoid neuralgia, pterygopalatine ganglion neuralgia, or sphenopalatine ganglion neuralgia)
