OBJECTIVE: To compare the curative effect of reoperation in short-term and percutaneous radiofrequency thermocoagulation (PRT) when trigeminal neuralgia patient after microvascular decompression (MVD) is invalid. METHODS: Follow-up of 54 patients (30 patients with reoperation in the short term, 24 patients with PRT of primitive trigeminal neuralgia) when MVD is invalid between January 2008 and December 2014. To evaluate the degree of pain relief and facial numbness of patients after the treatment in short-term (1 month), in long-term (1 year)...

We report a unique case of neurological deficit from late onset multiple sclerosis (MS), in a 65-year-old woman, after stereotactic radiosurgery (SRS) for trigeminal neuralgia (TN). At 3.5months post-SRS for TN, the patient developed ataxia and left leg paraesthesiae and brain MRI showed altered signal and enhancement in the vicinity of the right trigeminal root entry zone (REZ). The symptoms remitted following treatment with intravenous methylprednisolone, however, 10months post-SRS, the patient developed gait ataxia and left lower limb weakness...

We used resting-state fMRI to investigate regional homogeneity (ReHo) changes in patients with TN before and after PRT procedure, and to speculate about its possible mechanisms.Thirty-one TN patients underwent the PRT procedure had MRI scans just before and 6 months after surgery. The anatomical and resting-state functional images were all acquired. Patients' visual analog scales (VAS) scores, facial numbness, and disease duration were also recorded. Voxel-wise ReHo analysis was performed to detect the altered regional clusters after surgery...

OBJECTIVE: The purpose of this retrospective study was to compare and evaluate Percutaneous Retrogasserian Balloon Compression (PBC) and Gamma Knife Radiosurgery (GKRS) for the treatment of trigeminal neuralgia (TN) in patients with multiple sclerosis (MS). METHODS: In this single-center, retrospective comparative study, 202 patients with MS and concomitant TN were evaluated. A minimum follow-up of 24 months was required. Patients with a history of microvascular decompression or previous intervention were excluded...

The debilitating pain of trigeminal neuralgia often necessitates neurosurgical intervention via percutaneous transovale cannulation. While most percutaneous treatments of trigeminal neuralgia are successful, severe adverse events resulting from failure to properly cannulate the foramen ovale (FO) have been reported. With regard to specific targeting of particular trigeminal divisions (ie, V1, V2, V3, and combinations thereof), operative techniques have been described; however, these descriptions have not included specific angulation data...

Therapeutic strategy is controversial and not yet uniform for patients with trigeminal neuralgia (TN) and persistent or recurrent facial pain after microvascular decompression, percutaneous radiofrequency thermocoagulation (PRT), or Gamma Knife surgery. The outcomes and risks of PRT for these patients are not clearly understood. The authors performed a retrospective study of 84 patients with persistent or recurrent TN after surgery who then underwent PRT between 2007 and 2013. Data were obtained with chart review and telephone interviews...

BACKGROUND: Trigeminal neuralgia (TN) has been described in association with various primary headache disorders. So far, no case of TN has been reported in association with hemicrania continua (HC). CASE REPORT: Here, we report two patients of hemicrania continua associated with TN (HC-tic syndrome). These patients had both headaches concurrently. Both patients responded to a combination of carbamazepine and indomethacin. The skipping or tapering of carbamazepine led to the recurrence of the neuralgic pain of TN...

Percutaneous radiofrequency thermocoagulation (RFT) of the Gasserian ganglion is an effective treatment for primary trigeminal neuralgia (pTN). Currently Hartel anterior approach is the most commonly used method to access the Gasserian ganglion. However, this approach is associated with high recurrence rate and technical difficulties in certain patients with foramen ovale (FO) anatomical variations. In the present study, we assessed the feasibility of accessing the Gasserian ganglion through the FO from a mandibular angle under computed tomography (CT) and neuronavigation guidance...

BACKGROUND: Radiofrequency (RF) is a minimally invasive target-selective technique that has been used with success for many years in the treatment of different pathologies, such as low back pain, trigeminal neuralgia, and others. AIM: The aim of this study is to compare different mode of RF - continuous RF (CRF) versus pulsed RF (PRF) along with steroid in the management of low back pain of discogenic origin. SETTING AND DESIGN: Prospective, randomized, double-blind trial...

INTRODUCTION: Trigeminal neuralgia is one of the most disabling facial pain syndromes, with a significant impact on patients' quality of life. Pharmacotherapy is the first choice for treatment but cases of drug resistance often require new strategies, among which various interventional treatments have been used. In recent years a new therapeutic strategy consisting of botulinum toxin has emerged, with promising results. DEVELOPMENT: We reviewed clinical cases and case series, open-label studies and randomized clinical trials examining the use of botulinum toxin for drug-refractory trigeminal neuralgia published in the literature...

Although the microvascular decompression (MVD) surgery has become an effective remedy for cranial nerve rhizopathies, it is still challengeable and may result in a fatal sequel sometimes. Therefore, the operative skill needs to be further highlighted with emphasis on the safety and a preplan for management of postoperative fatal complications should be established. We retrospectively analyzed 6974 cases of MVD. Postoperatively, 46 patients (0.66 %) presented decline in consciousness with a positive finger-nose test (or failure to be tested) after wake up from the anesthesia, whom were focused on in this study...

The authors report a rare case of an intracranial dermoid cyst found in Meckel's cave. A 63-year-old woman developed left oculomotor nerve palsy and was referred to their hospital. Magnetic resonance imaging revealed a cystic lesion in the left Meckel's cave and prepontine cistern, but her symptoms gradually improved during conservative observation. However, three years later she complained of left facial pain in the territory of the second branch of the trigeminal nerve. The left oculomotor nerve palsy exacerbated again...

BACKGROUND: Pain relief comparable to radiofrequency thermocoagulation (RFT) alone and fewer side effects have been achieved by combination treatment with pulsed radiofrequency (PRF) and short-duration RFT in trigeminal neuralgia (TN). CASE DESCRIPTION: We report the successful management of recurrent TN following RFT with single PRF in two patients. The RFT treatment was performed in 2-3 cycles for each division with the lesion setting at 75-80°C for 90 s. The PRF treatment was applied for 120 s with a generator output of 45 V, not exceeding a temperature of 42°C at the tip of the electrode...

OBJECTIVES: This study was performed to obtain the clinicodemographic data regarding patients with trigeminal neuralgia (TN) treated at oral-maxillofacial medicine clinics, as there is a paucity of such information in the Asian setting. STUDY DESIGN: Retrospective multicenter study involving clinicodemographic information of 320 patients with TN diagnosed between 2001 and 2012 at eight regional oral-maxillofacial medicine clinics and followed up for at least 6 months...

Background and Study Aims In microvascular decompression of the trigeminal nerve for trigeminal neuralgia (TN), the site of conflict is occasionally difficult to identify. Endoscopy has been described to better evaluate the anatomical conflict in such situations. We hypothesized that indocyanine green (ICG) angiography could allow for better visualization of the compressing artery and its anatomical relation to the nerve. Material and Methods ICG angiography was performed in 17 TN patients undergoing microvascular decompression...

BACKGROUND: The mechanisms by which surgery and radiation elicit pain relief in trigeminal neuralgia (TN) secondary to mass lesions vary widely. We aimed to evaluate the outcomes of radiation to the nerve rather than to the lesion in the treatment of secondary TN. METHODS: We retrospectively reviewed all patients who underwent radiation at the University of California, Los Angeles for TN secondary to tumors. The Barrow Neurological Institute (BNI) pain score was used to evaluate pain outcomes...
