A case is presented of a 64-year-old female with a fifteen year history of right facial pain. The last nine years the facial pain is described as an intense, stabbing pain in the maxillary division of the right trigeminal nerve. The patient had Meniere's Disease for which an endolymphatic subarachnoid shunt was placed fifteen years prior. The patient underwent intensive medical and several surgical therapies for pain. Some of the procedures were initially successful but none provided lasting relief. Because of severe recurrent right facial pain, the patient underwent a right open partial rhizotomy of the trigeminal nerve via a retrosigmoid approach. Intraoperative findings included the end of the endolymphatic subarachnoid shunt in association with the trigeminal nerve roots. The end of the shunt was removed at the time of surgery. Postoperatively the patient has been pain free for thirty months. It is proposed a malpositioned or migrated endolymphatic subarachnoid shunt may be a cause of trigeminal neuralgia.
