REVIEW
Jeffery Mojica, Bi Mo, Andrew Ng
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...

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)...

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...

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...

PURPOSE: Stereotactic radiosurgery (SRS) provides a noninvasive treatment modality for patients with medically refractory trigeminal neuralgia. The root entry zone (REZ) has been proposed to be an ideal stereotactic target because it is partially composed of centrally produced myelin, conferring a theoretical increased sensitivity to irradiation as well as increased susceptibility to neurovascular conflict, making it the site in which nociceptive signals likely arise. The aim of this study is to determine if there is a statistically and clinically significant difference in pain relief or facial hypesthesia following SRS based on distance of the stereotactic isocenter from REZ...

BACKGROUND: Despite their huge epidemiological impact, primary headaches, trigeminal neuralgia and other chronic pain conditions still receive suboptimal medical approach, even in developed countries. The limited efficacy of current pain-killers and prophylactic treatments stands among the main reasons for this phenomenon. Botulinum neurotoxin (BoNT) represents a well-established and licensed treatment for chronic migraine, but also an emerging treatment for other types of primary headache, trigeminal neuralgia, neuropathic pain, and an increasing number of pain conditions...

OBJECTIVE Although CT-guided selective percutaneous radiofrequency thermocoagulation (PRFT) via the foramen rotundum (FR) has been used in the clinic as a novel successful treatment for isolated, second division (maxillary nerve [V2]), idiopathic trigeminal neuralgia (ITN), there is only very limited related literature published to date. This report aims to provide more detail for physicians about this technique. METHODS Between March 2013 and April 2014, 20 patients with isolated V2 ITN refractory to or intolerant of drug treatment were treated by CT-guided selective PRFT via the FR at the First Affiliated Hospital of Nanchang University...

OBJECTIVE Common surgical treatments for trigeminal neuralgia (TN) include microvascular decompression (MVD), stereotactic radiosurgery (SRS), and radiofrequency ablation (RFA). Although the efficacy of each procedure has been described, few studies have directly compared these treatment modalities on pain control for TN. Using a large prospective longitudinal database, the authors aimed to 1) directly compare long-term pain control rates for first-time surgical treatments for idiopathic TN, and 2) identify predictors of pain control...

Arterial neurovascular compression is hypothesised to be the main cause of primary trigeminal neuralgia. Although it is the most common cause, other pathologies, such as tumours in the cerebellopontine angle, can cause trigeminal pain. We report a case of a 44-year-old female patient with right trigeminal neuralgia without satisfactory response to medical treatment. Cerebral MRI showed no structural injuries. During microvascular decompression of the trigeminal nerve, endostosis of the internal aspect of the petrous bone was found to compress the trigeminal nerve...

INTRODUCTION:  Both microvascular decompression (MVD) and stereotactic radiosurgery (SRS) have been demonstrated to be effective in treating medically refractory trigeminal neuralgia. However, there is controversy over which one offers more durable pain relief and the patient selection for each treatment. We used a decision analysis model to calculate the health-related quality of life (QOL) for each treatment. METHODS:  We searched PubMed and the Cochrane Database of Systematic Reviews for relevant articles on MVD or SRS for trigeminal neuralgia published between 2000 and 2015...
