Numerous interventions for neuropathic pain (NeuP) are available, but its treatment remains unsatisfactory. We systematically summarized evidence from systematic reviews (SRs) of randomized controlled trials on interventions for NeuP. Five electronic databases were searched up to March 2015. Study quality was analyzed using A Measurement Tool to Assess Systematic Reviews. The most common interventions in 97 included SRs were pharmacologic (59%) and surgical (15%). The majority of analyzed SRs were of medium quality...

PURPOSE: To characterize quality-of-life (QOL) outcomes after stereotactic radiosurgery (SRS) for trigeminal neuralgia (TN). METHODS AND MATERIALS: The EuroQOL 5 Dimensions (EQ-5D) and Patient Health Questionnaire 9 (PHQ-9) were prospectively collected before and after SRS for 50 patients with TN. Pain response and treatment-related facial numbness were classified by Barrow Neurological Institute (BNI) scales. Differences in pooled QOL outcomes were tested with paired t tests and sign tests...

INTRODUCTION: Radiosurgery is now an established method of satisfactory pain control in patients with trigeminal neuralgia (TN). The Varian Truebeam STx (Varian Medical Systems, Palo Alto, CA) linear accelerator (LINAC) system is an arc-based, frameless stereotactic radiosurgery system used for the treatment of TN. To our knowledge, there has been only one published series of patient histories that documents the use of a frameless LINAC system for the treatment of TN. We describe the treatment parameters, patient outcomes, and complications associated with the treatment of TN...

Trigeminal neuralgia (TN) associated with multiple sclerosis (MS) was first described in Lehrbuch der Nervenkrankheiten für Ärzte und Studirende in 1894 by Hermann Oppenheim, including a pathologic description of trigeminal root entry zone demyelination. Early English-language translations in 1900 and 1904 did not so explicitly state this association compared with the German editions. The 1911 English-language translation described a more direct association. Other later descriptions were clinical with few pathologic reports, often referencing Oppenheim but citing the 1905 German or 1911 English editions of Lehrbuch...

INTRODUCTION: Patients with trigeminal neuralgia (TN) are often refractory to recommended first-line agents. Due to the absence of a systematic review, we undertook a network meta-analysis to assess various interventions that can be used to manage refractory TN. METHODS: Electronic databases were searched using appropriate strategies to identify randomized controlled clinical trials in patients with refractory TN, evaluating the proportion of patients with a minimum of 50% reduction in pain or a minimum of 2 cm reduction in score in an appropriate pain scale or complete pain relief by subjective pain scales...

BACKGROUND: Trigeminal neuralgia (TN) is the most common type of facial neuralgia with incidence of 26.8/100,000 person year. In general, this scenario is characterized by a lancinating, unilateral, paroxysmal pain in the area of the fifth cranial nerve. Several treatment methods, including the injection of ethyl alcohol or butyl alcohol into the ganglion, the glycerol injection into the trigeminal cistern, peripheral nerve divisions, the radiofrequency thermocoagulation of the preganglionic fibers, and radiosurgery has been used for TN...

Tetramethylpyrazine (TMP) has anti-inflammatory effects and is used to treat cerebral ischemic injury, but the mechanism of TMP on neural protection is not clear. Trigeminal neuralgia (TN) is a facial pain syndrome that is characterized by paroxysmal, shock-like pain attacks located in the somatosensory distribution of the trigeminal nerve. P2X3 receptor plays a crucial role in facilitating pain transmission. The present study investigates the effects of TMP on trigeminal neuralgia transmission mediated by P2X3 receptor of the trigeminal ganglia (TG)...

OBJECTIVE: To investigate the characteristics of brainstem trigeminal evoked potentials (BTEP) waveform in patients with and without trigeminal neuralgia (TN), and to discuss the utility of BTEP in patients with primary TN treated by microvascular decompression (MVD). METHODS: A retrospective review of 43 patients who underwent BTEP between January 2016 and June 2016, including 33 patients with TN who underwent MVD and 10 patients without TN. Brainstem trigeminal evoked potentials characteristics of TN and non-TN were summarized, in particular to compare the BTEP changes between pre- and post-MVD, and to discover the relationship between BTEP changes and surgical outcome...

Introduction Although it is widely accepted that facial pain paroxysms triggered by innocuous stimuli constitute a hallmark sign of trigeminal neuralgia, very few studies to date have systematically investigated the role of the triggers involved. In the recently published diagnostic classification, triggered pain is an essential criterion for the diagnosis of trigeminal neuralgia but no study to date has been designed to address this issue directly. In this study, we set out to determine, in patients with trigeminal neuralgia, how frequently triggers are present, which manoeuvres activate them and where cutaneous and mucosal trigger zones are located...

OBJECTIVE Stereotactic radiosurgery (SRS) is an important alternative management option for patients with small- and medium-sized vestibular schwannomas (VSs). Its use in the treatment of large tumors, however, is still being debated. The authors reviewed their recent experience to assess the potential role of SRS in larger-sized VSs. METHODS Between 2000 and 2014, 35 patients with large VSs, defined as having both a single dimension > 3 cm and a volume > 10 cm(3), underwent Gamma Knife radiosurgery (GKRS)...

Trigeminal neuralgia (TN) is a chronic neuropathic facial pain disorder that commonly responds to surgery. A proportion of patients, however, do not benefit and suffer ongoing pain. There are currently no imaging tools that permit the prediction of treatment response. To address this paucity, we used diffusion tensor imaging (DTI) to determine whether pre-surgical trigeminal nerve microstructural diffusivities can prognosticate response to TN treatment. In 31 TN patients and 16 healthy controls, multi-tensor tractography was used to extract DTI-derived metrics-axial (AD), radial (RD), mean diffusivity (MD), and fractional anisotropy (FA)-from the cisternal segment, root entry zone and pontine segment of trigeminal nerves for false discovery rate-corrected Student's t-tests...

PURPOSE OF REVIEW: The increasing number of publications on pulsed radiofrequency (PRF) treatment of chronic pain reflects the interest for this technique. We summarize the literature for PRF in five indications: radicular pain, trigeminal neuralgia (TN), occipital neuralgia, shoulder and knee pain. RECENT FINDINGS: The efficacy and safety of PRF adjacent to the dorsal root ganglion was documented on cervical and on lumbar level.PRF has been used for the treatment of TN...

Microvascular decompression (MVD) is a novel surgical procedure predominantly performed for treating trigeminal neuralgia (TN) and hemifacial spasm (HS). Multiple studies have proven the long-term success of MVD for both these conditions. The most common complications of MVD reported include chemical meningitis, facial hypesthesia, cerebrospinal fluid leak, facial paresis, and hearing loss. Delayed facial palsy (DFP) is an uncommon complication mostly noted in MVD for HS and after the removal of acoustic tumors...

Mixed connective tissue disorder (MCTD) is a multisystem disease with overlapping features of other autoimmune diseases, such as systemic lupus erythematosus (SLE), myositis, rheumatoid arthritis, and scleroderma. MCTD presents with a distinctive antibody in serum known as U1-ribonucleoprotein (RNP). MCTD is quite rare as compared to other connective tissue disorders like SLE, systemic sclerosis, dermatomyositis, and polymyositis. We describe a case of MCTD in a young Asian female of 30 year old. This case highlights rare co-existence of polyneuropathy and autoamputation in MCTD disorder...

Javier Ros de San Pedro
Posterior communicating aneurysms are commonly associated with oculomotor nerve palsy. However, trigeminal nerve involvement among these aneurysms is a rare event with no previous analysis. In order to describe the main features of posterior communicating aneurysms causing trigeminal neuralgia (TGN-PComAAs) eight cases (six from the literature plus two more illustrative cases) were included in the present series. All cases were thoroughly studied in order to collect their epidemiological, radiological, clinical, therapeutic, pathogenic, and outcome data...

We report a hitherto undescribed persistent carotid vertebral anastomosis associated with ipsilateral internal carotid artery agenesis and bilateral duplication of the intradural vertebral arteries. This rare anomaly was detected on MRI, supplemented by CT angiography while evaluating for cause trigeminal neuralgia in a 37-year-old woman. The aberrant vessel was seen to cause thinning and lateral displacement of the left trigeminal nerve on CISS 3D images. Also noted was a bilateral vertebral artery duplication of the PSA variant with the posterior inferior cerebellar artery arising from the medial limb of the duplication on the left...

Prepontine epidermoid is a rare congenital tumour which arises during 3rd - 5th week of embryogenesis due to incomplete separation of neuroectoderm from surface ectoderm. This is slow growing benign tumour with late presentation in adult life. The clinical symptoms depend on the location of the tumour. In this case, the patient had intractable bilateral trigeminal neuralgia. The patient was given conservative treatment for 8 weeks with carbamazipine, but it did not respond to the neuralgic pain medication. Another trial of combined neuropathic medications including carbamazepine, gabapentin, pregabalin and baclofen were given for another 8 weeks, but the symptoms continued...

Herpes zoster along the maxillary division of the trigeminal nerve is a rare condition that is caused by reactivation of the varicella zoster virus that resides within the trigeminal ganglion after the primary infection of chickenpox. The disease may be manifested as a toothache during its prodromal stage. The active stage of the disease is characterized by the appearance of a vesicular rash. Postherpetic neuralgia is a common complication of herpes zoster after resolution of the facial and intraoral symptoms...
