Trigeminal neuralgia is one of the most common causes of facial pain. It implies short lasting episodes of unilateral electric shock-like pain with abrupt onset and termination, in the distribution of one or more divisions of the trigeminal nerve that are triggered by innocuous stimuli. Most cases of trigeminal neuralgia are caused by compression of the trigeminal nerve root. Depending on the e...

Trigeminal neuralgia (TN), also known as tic douloureux, is a pain syndrome recognizable by patient history alone. The condition is characterized by intermittent unilateral facial pain. The pain follows the unilateral (>95%) sensory distribution of trigeminal nerve (V), typically radiating to the maxillary (V2) or mandibular (V3) area. Ophthalmic division (V1) pain alone occurs in <5% patients....

Pure trigeminal motor neuropathy is characterized by trigeminal motor weakness without signs of trigeminal sensory or other cranial nerve involvement. We describe a 63-year-old woman with progressive weakness and atrophy of the left masticatory muscles. She had no sensory disturbance. The diagnosis of pure trigeminal motor neuropathy was made on the basis of clinical and electrophysiologic stud...

objective: to evaluate sensorimotor nerve damage in patients with maxillofacial trauma referring to taleghani hospital, tehran, iran methods: this cross-sectional study was conducted during a 2-year period from 2014 to 2012 in taleghani hospital of tehran. we included a total number of 495 patients with maxillofacial trauma referring to our center during the study period. the demographic inform...

Anesthesia dolorosa is an uncommon deafferentation pain that can occur after traumatic or surgical injury to the trigeminal nerve. This creates spontaneous pain signals without nociceptive stimuli. Compression of the trigeminal nerve due to acoustic neuromas or other structures near the cerebellopontine angle (CPA) can cause trigeminal neuralgia, but the occurrence of anesthesia dolorosa subseq...

The trigeminocerebellar artery (TCA) is a branch of the basilar artery that may have an intraneural course and may cause trigeminal neuralgia. We report a case of trigeminal neuralgia with right vertebral artery aneurysm caused by an intraneural TCA that compressed the trigeminal nerve in multiple places. We performed proximal trapping for the fusiform aneurysm with extra-intracranial bypass to...

Trigeminal neuralgia is classically associated with neurovascular compression of the trigeminal nerve, at the root entry zone (REZ). However, patients are occasionally affected by intra-axial involvement of trigeminal sensory fibers caused by demyelinating diseases, strokes and, rarely, pontine cavernous malformations. We discuss the management strategies and decision-making process in a 55-yea...

A 69-year-old woman developed acute pain in the left trigeminal and glossopharyngeal nerve distributions. MR imaging demonstrated a left lateral medullary infarction (LMI) involving the left spinotrigeminal nucleus and tract, nucleus ambiguus, and solitary nucleus. Most patients presenting with trigeminal neuralgia will have disease involving the trigeminal nerve or ganglion or the primary sens...

Abstract Background Trigeminal neuralgia (TN) is an electric-like recurrent pain of a sudden onset and localized to the area supplied by trigeminal nerve, patients are usually free in between attacks. It’s one most common causes facial commonly induced mechanical irritation, there’s strong evidence suggesting insult at nerve root which caused neurovascular compression. The aim study was evaluat...

A 49 year-old man with trigeminal neuralgia caused by megadolichobasilar anomaly was described. The patient having neuralgic attacks in the second branch of the right trigeminal nerve for two and a half years showed the angiographic evidence of a tortuous and elongated vertebrobasilar artery and MRI of the brain clearly visualized the root entry zone of the nerve having been compressed by the m...
