Trigeminal nerve activity mediates head pain after cranial injuries, and also contributes to idiopathic syndromes such as cluster headache and trigeminal neuralgia. Nevertheless, chronic facial pain sometimes develops after lesion of the trigeminal nerve. Here we report on a patient who developed dysaesthesia and stabbing pain in her face after the trigeminal ganglion was destroyed. Transcutaneous electrical stimulation within the distribution of trigeminal deafferentation alleviated the anaesthesia dolorosa and neuralgic jabs, suggesting that sensory afferents that bypassed the trigeminal ganglion mediated therapeutic effects.
