OBJECTIVE Glossopharyngeal neuralgia (GPN) is a rare and disabling condition. Just as for trigeminal neuralgia, Gamma Knife radiosurgery (GKRS) is increasingly proposed as a therapeutic option for GPN. The purpose of this study was to assess long-term safety and efficacy of GKRS for this indication. METHODS From 2007 to 2015, 9 patients (4 male and 5 female) underwent a total of 10 GKRS procedures. All of the patients presented with GPN that was refractory to all medical treatment, and all had a long history of pain...

BACKGROUND: Vagal nerve stimulation (VNS) for refractory epilepsy is well established. Trigeminal neuralgia itself is a common disease in adults, and thus, late-onset pain in the trigeminal region under VNS, which is extremely rare, may not be recognized as caused by VNS. CASE PRESENTATION: Two patients with drug-resistant symptomatic epilepsy treated with chronic VNS experienced stimulation-related pain in the lower and upper jaw and teeth on the side of stimulation...

Osteogenesis imperfecta (OI) is a bone disorder that can lead to skull base deformities such as basilar invagination, which can cause compression of cranial nerves, including the trigeminal nerve. Trigeminal neuralgia in such cases remains a challenge, given distorted anatomy and deformities. We present an alternative option, consisting in cannulation of the foramen ovale and classical percutaneous treatment. Percutaneous balloon microcompression was performed in a 28 year-old woman with OI and severe trigeminal neuralgia using computed tomography (CT) and radiographic-guided cannulation of the Gasserian ganglion without neuronavigation or stereotactic devices...

Sarah K B Bick, Emad N Eskandar
Trigeminal neuralgia is characterized by severe, episodic pain in the trigeminal nerve distribution. Medical therapy is the first line treatment. For patients with refractory pain, a variety of procedures including microvascular decompression, percutaneous radiofrequency rhizotomy, percutaneous glycerol rhizotomy, percutaneous balloon compression, and stereotactic radiosurgery are available. We review the literature and suggest that microvascular decompression remains the gold standard operative therapy. For patients with recurrent pain or who are poor operative candidates, percutaneous radiofrequency rhizotomy offers the best pain response rates and has the advantage of being able to selectively target affected trigeminal divisions...

BACKGROUND: Neurovascular-compression syndrome (NCS) is described as a prominent pathological contact between cranial nerves and vessels. Trigeminal neuralgia, hemifacial spasm, and glossopharyngeal neuralgia are typical clinical entities associated with NCS. On the other hand, the hyoglossal nerve is rarely affected by NCS. CASE DESCRIPTION: We present a case of hypoglossal nerve palsy (HNP) secondary to vertebral artery (VA) compression. A 47-year-old man presented to our hospital with a 1-month history of dysarthria and dysphagia...

Trigeminal-mediated headshaking is an idiopathic neuropathic facial pain syndrome in horses. There are clinical similarities to trigeminal neuralgia, a neuropathic facial pain syndrome in man, which is usually caused by demyelination of trigeminal sensory fibers within either the nerve root or, less commonly, the brainstem. Our hypothesis was that the neuropathological substrate of headshaking in horses is similar to that of trigeminal neuralgia in man. Trigeminal nerves, nerve roots, ganglia, infraorbital, and caudal nasal nerves from horse abattoir specimens and from horses euthanized due to trigeminal-mediated headshaking were removed, fixed, and processed for histological assessment by a veterinary pathologist and a neuropathologist with particular experience of trigeminal neuralgia histology...

BACKGROUND: A recent study showed that 50% of patients who suffered from refractory neuralgia of the infraorbital nerve obtained satisfactory efficacy after pulsed radiofrequency (PRF) treatment. A pilot study showed that increasing the output voltage of PRF significantly improved the efficacy for trigeminal neuralgia; however, whether increasing the output voltage of PRF can improve the treatment outcomes for neuralgia of the infraorbital nerve is unknown. OBJECTIVE: To evaluate the efficacy and safety of high voltage PRF treatment in comparison with standard voltage PRF for neuralgia of the infraorbital nerve...

OBJECTIVE: To prospectively evaluate the morphological and structural changes of trigeminal nerve in patients with trigeminal neuralgia (TN) and to perform a comparison with healthy controls. METHODS: We conducted a prospective case-control study of 60 consective patients diagnosed with TN and 30 sex-and age-matched healthy controls. All subjects underwent high-resolution three-dimensional MRI. The volume and length of the cisternal segment of trigeminal nerve and the angle between the trigeminal nerve and the anterior surface of the pons (trigeminal pontine angle) were measured and compared...

OBJECTIVE Approximately 75%-92% of patients with trigeminal neuralgia (TN) achieve pain relief after Gamma Knife surgery (GKS), although a proportion of these patients will experience recurrence of their pain. To evaluate the reasons for durability or recurrence, this study determined the impact of trigeminal nerve length and volume, the nerve dose-volume relationship, and the presence of neurovascular compression (NVC) on pain outcomes after GKS for TN. METHODS Fifty-eight patients with 60 symptomatic nerves underwent GKS for TN between 2013 and 2015, including 15 symptomatic nerves secondary to multiple sclerosis (MS)...

Venous compression is a rare cause of trigeminal neuralgia (TN). Vascular decompression of the trigeminal nerve root, as the only etiopathogenetic treatment of trigeminal neuralgia, is a well-known procedure that is extensively used at various neurosurgical clinics. As the number of interventions for TN increases, the absolute number of surgeries for eliminating venous compression of the trigeminal nerve also grows. Five hundred TN patients underwent surgery at the Neurosurgical Institute in the period from 2000 to 2015...

Occipital neuralgia generally responds to medical or invasive procedures. Repeated invasive procedures generate increasing complications and are often contraindicated. Stereotactic radiosurgery (SRS) has not been reported as a treatment option largely due to the extracranial nature of the target as opposed to the similar, more established trigeminal neuralgia. A dedicated phantom study was conducted to determine the optimum imaging studies, fusion matrices, and treatment planning parameters to target the C2 dorsal root ganglion which forms the occipital nerve...

BACKGROUND: Combined hyperactive dysfunction syndrome (HDS) is defined as the combination symptoms arising from overactivity in cranial nerves specifically, trigeminal neuralgia (TN), hemifacial spasm (HFS), and glossopharyngeal neuralgia (GPN) without an obvious explanatory structural lesion. The study aims to retrospectively analyze the clinical characteristics of combined HDS treated with microvascular decompression (MVD) in a single institution. METHODS: A total of 1450 patients with HDS were treated with MVD in our department during a 10-year period, among which 44 cases of combined HDS were identified...

Objectives.:  Percutaneous radiofrequency ablation (RFA) of the gasserian ganglion through the foramen ovale and the glossopharyngeal nerve at the jugular foramen is a classical approach to treating trigeminal neuralgia (TN) and glossopharyngeal neuralgia (GPN), respectively. However, it can be technically challenging with serious complications. We have thus developed a novel technique utilizing C-arm and computerized tomography (CT) guidance to block TN and GPN. Our goals were to describe a three-dimensional image-based technique to improve patient comfort and to decrease procedural time associated with needle guidance...

To investigate the characteristics of symptomatic trigeminal neuralgia (TN) caused by tumors and the relationship between anatomicosurgical findings and tumor type, the authors undertook a retrospective review of 35 patients with symptomatic TN between 2006 and 2015. The tumors included 16 meningiomas, 14 epidermoids, 4 vestibular schwannomas, and 1 hemangioblastoma. The studies show that patients with tumor-induced TN were significantly younger than those idiopathic TN (P <0.05). Meningioma-induced TN tended to have responsible vessels, while epidermoid tumor seemed to cause TN by wrapping or compressing the nerve...

BACKGROUND: Trigeminal neuralgia (TN) affects 7% of patients with multiple sclerosis (MS). In such patients, TN is difficult to manage either pharmacologically and surgically. Radiosurgical rhizotomy is an effective treatment option. The non-isocentric geometry of radiation beams of CyberKnife introduces new concepts in the treatment of TN. Its efficacy for MS-related TN has not yet been demonstrated. METHODS: Twenty-seven patients with refractory TN and MS were treated...

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...

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...
