BACKGROUND: Schwannomas arising from the cranial nerves controlling extraocular eye movements are very rare and usually present with some degree of diplopia. CASE DESCRIPTION: We report a 50-year-old woman who presented with isolated left-sided trigeminal neuralgia of six months' duration. Imaging demonstrated a homogeneously enhancing mass in the left ambient cistern, and the patient was taken to the operating room for resection. A retrosigmoid approach was used, and the mass was directly visualized arising from the trochlear nerve and compressing on the dorsal root entry zone of the trigeminal nerve...

PURPOSE OF REVIEW: Sphenopalatine ganglion (SPG) block has been used by clinicians in the treatment of a variety of headache disorders, facial pain syndromes, and other facial neuralgias. The sensory and autonomic fibers that travel through the SPG provided the scientific rationale for symptoms associated with these head and neck syndromes. Yet, despite the elucidation of this pathogenic target, the optimal method to block its pain-producing properties has not been determined. Clinicians have developed various invasive and non-invasive techniques, each of which has shown variable rates of success...

Hydrocephalus has rarely been reported to be associated with trigeminal neuralgia. Here we report for the first time a case of trigeminal neuralgia associated with hydrocephalus, whose symptoms completely resolved twice after ventriculoperitoneal shunting. The patient had a high-voltage electric shock to his head, which has not been reported in a patient with ventriculoperitoneal shunt to the best of our knowledge. The possible underlying mechanism of this situation is discussed in addition to a brief review of the literature...

Background Persistent idiopathic facial pain (PIFP) is a chronic disorder recurring daily for more than two hours per day over more than three months, in the absence of clinical neurological deficit. PIFP is the current terminology for Atypical Facial Pain and is characterized by daily or near daily pain that is initially confined but may subsequently spread. Pain cannot be attributed to any pathological process, although traumatic neuropathic mechanisms are suspected. When present intraorally, PIFP has been termed 'Atypical Odontalgia', and this entity is discussed in a separate article in this special issue...

To investigate the behavioral and biomolecular similarity between neuralgia and depression, a trigeminal neuralgia (TN) mouse model was established by constriction of the infraorbital nerve (CION) to mimic clinical trigeminal neuropathic pain. A mouse learned helplessness (LH) model was developed to investigate inescapable foot-shock-induced psychiatric disorders like depression in humans. Mass spectrometry was used to assess changes in the biomolecules and signaling pathways in the hippocampus from TN or LH mice...

We report the successful surgical management of three patients with trigeminal neuralgia and hydrocephalus. MRI revealed no neurovascular contact at the trigeminal root entry zone. Trigeminal neuralgic symptoms were controlled following alleviation of hydrocephalus. We hypothesize that trigeminal nerve traction, secondary to hydrocephalus, as the cause for their trigeminal neuralgia.

Definition and taxonomy This review deals with neuropathic pain of traumatic origin affecting the trigeminal nerve, i.e. painful post-traumatic trigeminal neuropathy (PTTN). Symptomatology The clinical characteristics of PTTN vary considerably, partly due to the type and extent of injury. Symptoms involve combinations of spontaneous and evoked pain and of positive and negative somatosensory signs. These patients are at risk of going through unnecessary dental/surgical procedures in the attempt to eradicate the cause of the pain, due to the fact that most dentists only rarely encounter PTTN...

OBJECT: This study describes an experimental rabbit model that allows the reproduction of percutaneous operations that are used in patients with trigeminal neuralgia (TN). Attention was given to an exact anatomical description of the rabbit's middle cranial fossa as well as the establishment of conditions for a successful procedure. METHODS: Morphometric measurements were taken from 20 rabbit skulls and CT scans. The anatomy of the trigeminal nerve, as well as its surrounding structures, was assessed by bilateral dissection of 13 New Zealand white rabbits (NWR)...

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 trigeminal neuralgia and progressive facial nerve palsy. Magnetic resonance imaging revealed the presence of acoustic schwannoma involving facial nerve and trigeminal schwannoma of the cisternal part of the nerve involving gasserian ganglion (Meckel’s cave)...

BACKGROUND: Trigeminal neuralgia (TN) caused by vertebrobasilar dolichoectasia (VBD) is rare and needs further exploration. The purpose of this study is to investigate the clinical features and surgical treatment of TN caused by VBD. METHODS: 15 patients with TN caused by VBD were included in our study. The patient data regarding clinical characteristics, neuroimaging presentations, intraoperative findings and treatment outcomes were analyzed retrospectively. Moreover, the previous relevant literature was reviewed simultaneously...

BACKGROUND: Microvascular decompression (MVD) is a safe and effective treatment for trigeminal neuralgia (TGN). Cerebellar venous infarction is a complication associated with surgical sacrifice of the superior petrosal vein (SPV). The SPV intervenes between the trigeminal nerve and the surgeon. Optimal exposure of the cisternal trigeminal nerve, particularly at the brain stem, can be achieved by sacrificing the SPV. We analysed a cohort of 224 patients to determine the frequency of cerebellar venous infarction...

OBJECTIVES: Trigeminal neuralgia (TN) is the most common cranial neuralgia in adults, with a slight prevalence in women. Antiepileptic drugs represent the mainstay of the medical treatment, whereas microvascular decompression is the best option in case of neurovascular conflict. Although these treatments showed good rate of efficacy, they can be contraindicated in some patients and more than 50% of patients undergoing these treatments will present recurrence of pain in the following months...

PURPOSE OF REVIEW: Although trigeminal neuralgia is well known to neurologists, recent developments in classification and clinical diagnosis, new MRI methods, and a debate about surgical options necessitate an update on the topic. RECENT FINDINGS: Currently, a worldwide controversy exists regarding the classification, diagnostic process, and surgical treatment of trigeminal neuralgia. This controversy has been caused on one side by the recognition that some 50% of patients with trigeminal neuralgia, apart from characteristic paroxysmal attacks, also have continuous pain in the same territory, which results in greater diagnostic difficulties and is associated with a lower response to medical and surgical treatments...

BACKGROUND: Although secondary trigeminal neuralgia is usually due to tumours or multiple sclerosis, other major neurological diseases, such as aneurysms, should be taken into account when the history or the symptoms suggest a secondary origin. CASE DESCRIPTION: A 67-year-old lady presented with a 6-month history of trigeminal neuralgia involving exclusively the right ophthalmic division. A dedicated 3D-MRI-MRA study documented a very rare contact with a wide-necked aneurysm of the superior cerebellar artery, which distorted the trigeminal root...

INTRODUCTION: The classic form of trigeminal neuralgia is usually sporadic (no familial clustering). However, around 2% of all cases of trigeminal neuralgia may be familial. Describing this entity may be useful for diagnosing this process and may also be key to determining the underlying causes of sporadic classical trigeminal neuralgia. We report on cases in a series of 5 families with at least 2 members with classic trigeminal neuralgia, amounting to a total of 11 cases. MATERIAL AND METHODS: We recorded cases of familial classical trigeminal neuralgia between March 2014 and March 2015 by systematically interviewing all patients with a diagnosis of trigeminal neuralgia who visited the neurology department on an outpatient basis...

Objective. : Idiopathic trigeminal neuralgia (ITN) can be effectively treated with radiofrequency thermocoagulation. However, this procedure requires cannulation of the foramen ovale, and conventional cannulation methods are associated with high failure rates. Multimodality imaging can improve the accuracy of cannulation because each imaging method can compensate for the drawbacks of the other. We aim to determine the feasibility and accuracy of percutaneous foramen ovale cannulation under the guidance of virtual navigation with multimodality image fusion in a self-designed anatomical model of human cadaveric heads...

Background. : Short-lasting unilateral neuralgiform headache attack with conjunctival injection and tearing (SUNCT) is one of the trigeminal autonomic cephalalgias where neurovascular compression was detected in neuroimaging in recent years. Case. : We report two cases, a 52-year-old adult and a 69-year-old elderly patient with short-lasting and recurrent headache combined with cranial autonomic features. Diffusion tensor imaging (DTI) and magnetic resonance (MR) tractography of both patients outlined structural changes of the trigeminal nerve revealing neurovascular compression...

BACKGROUND: Latent varicella zoster virus reactivates mainly in sensory ganglia such as the dorsal root ganglion (DRG) or trigeminal ganglion. The DRG contains many receptor channels and is an important region for pain signal transduction. Sustained abnormal electrical activity to the spinal cord via the DRG in acute herpes zoster can result in neuropathic conditions such as postherpetic neuralgia (PHN). Although the efficacy of pulsed radiofrequency (PRF) application to the DRG in various pain conditions has been previously reported, the application of PRF to the DRG in patients with herpes zoster has not yet been studied...
