Trigeminal neuralgia: a practical guide.

Pract Neurol 2021 Jun 9. Epub 2021 Jun 9.

Headache and Facial Pain Group, UCL Queen Square Institute of Neurology, London, UK

Trigeminal neuralgia (TN) is a highly disabling disorder characterised by very severe, brief and electric shock like recurrent episodes of facial pain. New diagnostic criteria, which subclassify TN on the basis of presence of trigeminal neurovascular conflict or an underlying neurological disorder, should be used as they allow better characterisation of patients and help in decision-making regarding medical and surgical treatments. MR, including high-resolution trigeminal sequences, should be performed as part of the diagnostic work-up. Read More

Is trigeminal neuralgia the only definitive diagnosis for pain in a tooth extraction site?

BMC Oral Health 2021 Jun 7;21(1):291. Epub 2021 Jun 7.

Honorary Consultant in Orofacial Pain Department, International Campus Dental School, Tehran University of Medical Sciences, Tehran, Iran.

Knowing the International Classification of Orofacial Pain helps pain specialists to differentiate types of orofacial pain. It is important to select the best treatment or intervention for the patients based on the diagnosis. As part of our study, we reviewed the article published in BMC Oral Health, titled "Clinical characteristics and associated factors of trigeminal neuralgia: Experience from Addis Ababa, Ethiopia" by Ayele et al.

Frameless navigation-guided percutaneous rhizotomy of the trigeminal nerve: an appraisal of the literature.

Neurosurg Rev 2021 Jun 5. Epub 2021 Jun 5.

Neurosurgery Department, University Hospital Dr. Josep Trueta, Girona, Girona, Spain.

Percutaneous rhizotomy is a cornerstone of trigeminal neuralgia treatment. The procedure is classically performed under intermittent fluoroscopic guidance. While frameless navigation has been advanced to overcome potential difficulties and risks of the technique, literature on the subject is limited, and a gap between actual use and published series is likely.

Neuroimage Clin 2021 May 25;31:102706. Epub 2021 May 25.

Division of Brain, Imaging & Behaviour, Krembil Brain Institute, Toronto Western Hospital, University Health Network, Toronto, Ontario, Canada; Institute of Medical Science, Faculty of Medicine, University of Toronto, Toronto, Ontario, Canada; Department of Surgery, Faculty of Medicine, University of Toronto, Toronto, Ontario, Canada; Division of Neurosurgery, Krembil Neuroscience Centre, Toronto Western Hospital, University Health Network, Toronto, Ontario, Canada. Electronic address:

Background: Trigeminal neuralgia, a severe chronic neuropathic pain disorder, is widely believed to be amenable to surgical treatments. Nearly 20% of patients, however, do not have adequate pain relief after surgery. Objective tools for personalized pre-treatment prognostication of pain relief following surgical interventions can minimize unnecessary surgeries and thus are of substantial benefit for patients and clinicians.

Acute and Chronic Pain from Facial Skin and Oral Mucosa: Unique Neurobiology and Challenging Treatment.

Int J Mol Sci 2021 May 28;22(11). Epub 2021 May 28.

Health Science Center at San Antonio, Programs in Integrated Biomedical Sciences, Department of Oral & Maxillofacial Surgery, School of Dentistry, Translational Sciences, Biomedical Engineering and Radiological Sciences, University of Texas, San Antonio, TX 78229, USA.

The oral cavity is a portal into the digestive system, which exhibits unique sensory properties. Like facial skin, the oral mucosa needs to be exquisitely sensitive and selective, in order to detect harmful toxins versus edible food. Chemosensation and somatosensation by multiple receptors, including transient receptor potential channels, are well-developed to meet these needs. Read More

N58A Exerts Analgesic Effect on Trigeminal Neuralgia by Regulating the MAPK Pathway and Tetrodotoxin-Resistant Sodium Channel.

Toxins (Basel) 2021 May 17;13(5). Epub 2021 May 17.

School of Life Sciences and Biopharmaceutical Science, Shenyang Pharmaceutical University, Shenyang 110016, China.

The primary studies have shown that scorpion analgesic peptide N58A has a significant effect on voltage-gated sodium channels (VGSCs) and plays an important role in neuropathic pain. The purpose of this study was to investigate the analgesic effect of N58A on trigeminal neuralgia (TN) and its possible mechanism. The results showed that N58A could significantly increase the threshold of mechanical pain and thermal pain and inhibit the spontaneous asymmetric scratching behavior of rats. Read More

Retrosigmoid microvascular decompression as a treatment for trigeminal neuralgia in a patient with osteogenesis imperfecta.

Br J Neurosurg 2021 May 31:1-3. Epub 2021 May 31.

Department of Neurological Surgery, University of Pittsburgh Medical Center, Pittsburgh, PA, USA.

Individuals with osteogenesis imperfecta develop pathologic bone due to genetic defects in collagen synthesis. These patients are prone to skull base abnormalities with resultant lower cranial nerve deficits, most common of which is trigeminal neuralgia. Typically, such patients are managed medically, and surgical options are not well explored for those patients, who become refractory to medication management. Read More

Cranial Neuralgias.

Carrie Robertson

Continuum (Minneap Minn) 2021 06;27(3):665-685

Purpose Of Review: This article discusses the differential diagnosis, evaluation, and management of trigeminal neuralgia and reviews other neuralgias of the head and neck, including those that contribute to neuralgic ear pain.

Recent Findings: Most cases of trigeminal neuralgia are related to vascular compression, a demyelinating plaque, or a compressive mass affecting the trigeminal nerve. However, recent studies have shown that up to 11% of patients have a family history of trigeminal neuralgia, suggesting that some patients may have a genetic predisposition to demyelination or nerve hyperexcitability.

Department of Neuroscience, College of Medicine, Chungbuk National University, Cheongju, South Korea.

Background: Preceding studies have reported the association of chronic neuropathic orofacial pain with altered ongoing function in the ventrolateral periaqueductal gray (vlPAG). However, its role in trigeminal neuralgia (TN) lacks attention. We here reported the aspect that vlPAG neurons play in TN nociceptive processing by employing excitatory neuron-specific optogenetic approaches. Read More

[Pain in multiple sclerosis and neuromyelitis optica spectrum disorders].

Schmerz 2021 Jun 25;35(3):211-222. Epub 2021 May 25.

Institut für Klinische Neuroimmunologie, LMU Klinikum, Marchioninistr. 15, 81377, München, Deutschland.

Multiple sclerosis and neuromyelitis optica spectrum disorders are autoimmune inflammatory diseases of the central nervous system, which can lead to a multitude of neurological complaints and pain syndromes. Pain may be an acute symptom during disease exacerbation as well as a chronic symptom, whereby the latter sometimes substantially reduces the quality of life. The etiology of pain is very heterogeneous but the rapid differential diagnostic classification is decisive in order to be able to initiate a differentiated treatment strategy. Read More

Role of Greater Occipital Nerve Block in Headache Disorders: A Narrative Review.

Neurol India 2021 Mar-Apr;69(Supplement):S228-S256

Department of Neurology, GB Pant Institute of Post Graduate Medical Education and Research, New Delhi, India.

Background: The proximity of sensory neurons in the upper cervical spinal cord to the trigeminal nucleus caudalis (TNC) neurons and the convergence of sensory input to TNC neurons from both cervical and trigeminal fibers underscore the rationale of using greater occipital nerve block (GON-block) for acute and preventive treatment in various headache disorders.

Mol Pain 2021 Jan-Dec;17:17448069211016139

Department of Neurosurgery, Oslo University Hospital-Rikshospitalet, Oslo, Norway.

Trigeminal neuralgia (TN) is a severe facial pain disease of unknown cause and unclear genetic background. To examine the existing knowledge about genetics in TN, we performed a systematic study asking about the prevalence of familial trigeminal neuralgia, and which genes that have been identified in human TN studies and in animal models of trigeminal pain.
