Schwannomas are benign encapsulated tumors arising from the sheaths of peripheral nerves. They present as slowly enlarging solitary lumps, which may cause neurological defects. Multiple schwannomas in non-neurofi bromatosis type 2 patients are extremely rare. We report a case of a 60-year-old female patient, without any family history of neurofibromatosis or schwannomatosis, presented with trig...

BACKGROUND Patients presenting with bilateral trigeminal hypoesthesia may go on to have trigeminal isolated sensory neuropathy, a benign, purely trigeminal neuropathy, or facial-onset sensory motor neuronopathy (FOSMN), a malignant life-threatening condition. No diagnostic criteria can yet differentiate the two conditions at their onset. Nor is it clear whether the two diseases are distinct ent...

Trigeminal neuralgia is a very peculiar disease. The pain of trigeminal neuralgia, also known as “tic douloureux”, is characterized by episodic, paroxysmal, triggered pain in a distribution of 1 or more divisions of the trigeminal nerve. TN pain attacks may result from physiologic changes induced by a chronic partial injury to the brainstem trigeminal nerve root from a variety of causes. An ear...

100 patients with hemifacial spasm treated by microvascular decompression are presented. there were 60 females and 40 males. their ages ranged from 29 to 75 years with a median age of 54 years, and the left side was involved predominantly. the common focal signs were facial nerve palsy in 41 cases, diminished hearing in 14 cases, trigeminal neuralgia in 11 cases, and homolateral trigeminal neur...

A case of Herpes zoster of the mandibular nerve in an 80 year old man is reported. Herpes zoster infection affecting only the mandibular branch of the trigeminal nerve is rare. It is proposed that the distribution of lesions is a consequence of a unique latent site of the virus within neurons of the gasserian ganglion innervating the mandibular division of the trigeminal nerve.

Seven consecutive patients with multiple sclerosis and trigeminal neuralgia were investigated with MRI to determine the occurrence of a lesion which would account for the patients' pain. Two patients had bilateral symptoms. In the patients with unilateral trigeminal neuralgia vascular compression of the nerve by an artery at the root entry zone on the symptomatic side was confirmed in three pat...

It is well established that the majority of headache and other trigeminal nerve-associated disorders have higher prevalence in females than in males. However, the pathogenesis of many chronic trigeminal pain conditions, such as trigeminal neuralgia, migraine and temporo-mandibular disorders, is still not known. One of the proposed mechanisms involve calcitonin gene-related peptide (CGRP), which...

Headache syndromes often involve occipital and neck symptoms, suggesting a functional connectivity between nociceptive trigeminal and cervical afferents. Although reports regarding effective occipital nerve blockades in cluster headache exist, the reason for the improvement of the clinical symptoms is not known. Using occipital nerve blockade and nociceptive blink reflexes, we were able to demo...

Pure trigeminal motor neuropathy is a rare clinical manifestation, and its etiology remains obscure. Here, we report the case of a 67-year-old woman who presented with jaw deviation to the right. Neurological examination revealed atrophy of the right temporal and masseter muscles and jaw deviation to the right. Absence of other cranial nerve abnormalities, such as loss of sensation in the trige...

INTRODUCTION Several studies on cadavers dissection have shown that collateral branches of the trigeminal nerve cross muscle bundles on their way, being a possible etiological factor of some nerve disturbances. CASE REPORT A 45-year-old man attended to the Temporomandibular Joint and Orofacial Pain Unit of the Master of Oral Surgery and Implantology in Hospital Odontològic of Barcelona Univer...
