Compared to oxcarbazepine and carbamazepine, botulinum toxin type A is a useful therapeutic option for trigeminal neuralgia symptoms: A systematic review.

OBJECTIVES: This review aimed to compare the effectiveness of three treatments: BTX A, CBZ, and OXB, in managing trigeminal neuralgia (TN). MATERIAL AND METHODS: We conducted a thorough search for research articles related to our issue using specific keywords on several databases, including Cochrane Central Register of Controlled Trials, Science Direct, Scopus, PubMed, Elsevier, Springer Journals, Ovid Medline, EBSCO, and Web of Science. Our focus was on publications from 1965 to 2023. RESULTS: We retrieved 46 articles from the search and reviewed them carefully. Out of these, we selected 29 articles that met the inclusion criteria. Among the selected articles, 11 investigated the effects of CBZ and OXB, while 18 explored the impact of BTX A on the improvement of TN symptoms. The response rate ranged between 56% and 90.5% for CBZ and between 90.9% and 94% for OXB. The response rate for BTX A ranged between 51.4% and 100%. All these three treatments had a remarkable effect on the improvement of TN. Importantly, findings highlighted that side effects of CBZ and OXB could lead to treatment discontinuation in some cases, whereas BTX A's side effects have been minimal and less frequent. CONCLUSIONS: Consequently, BTX A emerges as a promising alternative for TN treatment. However, additional clinical trials are necessary to validate this finding, and further research is required to establish a standardized protocol for administering BTX A in TN.

Trigeminal and Glossopharyngeal Neuralgia.

Trigeminal neuralgia and glossopharyngeal neuralgia are craniofacial pain syndromes characterized by recurrent brief shock-like pains in the distributions of their respective cranial nerves. In this article, the authors aim to summarize each condition's characteristics, pathophysiology, and current pharmacotherapeutic and surgical interventions available for managing and treating these conditions.

Other Secondary Headaches: Odontogenic Pain and Other Painful Orofacial Conditions.

This article discusses extremely common odontogenic pain conditions, which may occasionally present to the neurology clinic mimicking headache, and other uncommon orofacial pain conditions, which may do the same. Typical presentations, investigative strategies, and management are discussed, as well as highlighting key diagnostic criteria and the importance of involving oral or dental specialists where diagnostic uncertainty exists.

Trigeminal neuralgia and trigeminal neuropathic pain.

It is very important that the dental team are aware of the varied presentations of pain in the mouth, face and other parts of the trigeminal region which are not directly caused by teeth or oral structures. Our understanding of underlying causes in this complex area is evolving. Ultimately, patients who present with what may at first seem to be oral or dental problems will require specialist input in secondary care with potential for use of systemic medications. This article reviews the common non-dental pains encountered in the orofacial region related to dysfunction of the trigeminal nerve.

[Specificities of orofacial neuropathic pain]. / Spécificités de la douleur neuropathique oro-faciale.

Head pain and notably orofacial pain differs from spinal pain on pathophysiological, clinical, therapeutic and prognostic levels. Its high prevalence, important impact on quality of life and significant socio-economical burden justify specific study of such type of pain. Among them, neuropathic orofacial pain resulting from disease or trauma of the trigeminal nervous system is among the most difficult types of pain to diagnose and to treat. Deciphering of underlying peripheral and central mechanisms has allowed numerous conceptual, clinical and therapeutic advances, notably the role of neural and non neural cell types, such as glia, immunocytes, vascular endothelial cells or the role of trigeminal sensory complex neural circuitry reconfiguration in the development of post-traumatic trigeminal neuropathic pain. Cellular interactions within the trigeminal ganglion, allowing a better understanding of several painful dental, ocular or cephalalgic comorbidities, are also described.

Title: Spécificités de la douleur neuropathique oro-faciale. Abstract: Les douleurs de la région céphalique ­ et notamment les douleurs oro-faciales ­ diffèrent des douleurs spinales sur les plans physiopathologique, clinique, thérapeutique et pronostique. Leur prévalence élevée, leur fort retentissement sur la qualité de vie individuelle et leur impact économique et sociétal important justifient une étude spécifique. Parmi ces douleurs, les douleurs neuropathiques, résultant d'une maladie ou d'un traumatisme du système nerveux trigéminal, sont parmi les plus difficiles à diagnostiquer et à soigner. L'étude des mécanismes neurobiologiques, périphériques et centraux les sous-tendant a permis de nombreuses avancées conceptuelles, cliniques et thérapeutiques, avec, par exemple, la mise en évidence du rôle des cellules nerveuses et non nerveuses, telles que la glie, les immunocytes, les cellules endothéliales vasculaires ou le rôle de la reconfiguration de la circuiterie nerveuse au niveau du complexe sensitif trigéminal, dans la genèse des douleurs neuropathiques post-lésionnelles. Les interactions cellulaires au sein du ganglion trigéminal, susceptibles d'éclairer la compréhension de certaines comorbidités douloureuses dentaires, oculaires ou céphalalgiques, sont également décrites.

Knowledge and experience of dentists with patients with trigeminal neuralgia: A prospective, cross-sectional survey study.

OBJECTIVE: Trigeminal neuralgia (TN) and orofacial pain (OFP) patients frequently refer to dentists. It is often confused with odontogenic pain and dental procedures are performed. In this study, the authors aimed to reveal the knowledge and experience of dentists about TN. METHODS: This is a cross-sectional study that includes dentists who participate in volunteering via an online questionnaire. The questionnaire form contains demographic data, TN treatment, and diagnosis consisting of 18 questions. RESULTS: The data of 229 dentists were examined. Almost 82% of the participants reportedly knew the diagnostic criteria of TN and 61.6% reported that they had previously referred patients with TN. The most frequently confused diagnosis was odontogenic pains (45.9%). CONCLUSION: TN diagnostic criteria should be included more often in the education of dentists. Thus, it is possible to prevent unnecessary dental procedures. There is a need to increase knowledge on this subject with further studies involving dental students.

A rare case of vestibular schwannoma manifesting as trigeminal neuralgia.

BACKGROUND: In this case report, the authors reviewed a rare case of a vestibular schwannoma manifesting as trigeminal neuralgia (TN). Intracranial tumors can have a variety of orofacial pain symptoms. Among benign cerebellopontine angle tumors, vestibular schwannoma is the most common cause of a TN-like manifestation. Although the most common symptoms of a vestibular schwannoma are hearing loss and vestibulopathy, the unique feature of this case was the manifestation of symptoms consistent with TN. CASE DESCRIPTION: The patient had right-sided episodic facial pain that was short in duration and severe in intensity. The initial differential diagnoses included short-lasting, unilateral, neuralgiform headache attacks with conjunctival injection and tearing and TN. As part of the routine evaluation, the patient was referred for brain magnetic resonance imaging, which revealed a right-sided vestibular schwannoma. The patient was prescribed 200 mg of gabapentin 3 times daily and was referred to neurosurgery for excision of the schwannoma. Surgical excision resulted in complete resolution of pain. PRACTICAL IMPLICATIONS: This case illustrates the importance of interdisciplinary treatment and how it can lead to an optimal outcome for a patient with complex orofacial pain symptoms.

Sixth cranial nerve palsy and trigeminal neuropathic pain due to a space-occupying lesion.

Various neuropathies of the cranil nerves can accompany trigeminal neuropathic pain attributed to space-occupying lesions. In this case report, the patient presented with persistent intraoral pain and numbness on the right side of the face. Cranial nerve examination revealed dysfunctional eye movements, diplopia, and mechanical hyposensitivity in the mandibular region. The patient was diagnosed with neuropathy due to intracranial lesions and referred to the Department of Neurosurgery and Otorhinolaryngology. The patient was suspected of having malignant lymphoma and is currently undergoing neurosurgical intervention. This article discusses the importance of the examination of the cranial nerve for patients with persistent pain in the trigeminal nerve distribution.

Clinical observation of perioperative negative emotional changes in patients with percutaneous balloon compression for primary trigeminal neuralgia: A prospective cohort study.

OBJECTIVE: To investigate the prevalence of negative emotions in trigeminal neuralgia (TN) patients, to identify risk factors associated with anxiety and depression, and further to explore the impact of percutaneous balloon compression (PBC) on anxiety and depression in TN patients during the perioperative period. METHODS: 400 patients with primary TN treated with PBC at our institution from November 2021 to April 2023 were included. We analyzed visual analogue scale (VAS) and the Hospital Anxiety and Depression Scale (HADS) scores. The patients' clinical data and short-term clinical outcomes were gathered and subjected to statistical analysis. RESULTS: This study included a total of 400 patients diagnosed with primary TN. Patients who had high pain intensity (OR 1.20, 95 % CI 1.02-1.41; p = 0.025) or a history of multiple previous TN procedures (OR 1.49, 95 % CI 1.03-2.16; p = 0.036), were more prone to anxiety. Patients who were female (OR 1.59, 95 % CI 1.03-2.44; p = 0.036), had high pain intensity (OR 1.28, 95 % CI 1.08-1.52; p = 0.004) or had a history of multiple previous TN procedures (OR 1.48, 95 % CI 1.11-1.98; p = 0.008), were more likely to have depression. Significant improvements in anxiety and depressive symptoms were observed in patients who experienced pain relief after PBC (p < 0.001). CONCLUSIONS: Female gender, high pain intensity, and a history of multiple prior TN procedures are associated risk factors for anxiety and depression in TN patients. PBC can provide patients with a high pain relief rate and significantly improve their anxiety and depression symptoms during the perioperative period.

SUNCT/SUNA: ¿frecuentemente mal diagnosticada como neuralgia del trigémino? / SUNCT/SUNA: frequently misdiagnosed as trigeminal neuralgia?

Objetivo: Identificar el número de casos con posible diagnóstico de cefalea neuralgiforme unilateral de corta duración con inyección conjuntival y lagrimeo (SUNCT) o cefalea neuralgiforme unilateral de corta duración con síntomas autonómicos craneales (SUNA) en pacientes con un previo diagnóstico de neuralgia del trigémino (NT) en el servicio de neurología del Centro Médico Nacional 20 de Noviembre, comprobando así que estas cefaleas trigeminoautonómicas deben ser descartadas y consideradas como diagnósticos diferenciales de la NT. Pacientes y métodos: Estudio transversal y retrospectivo. Se evaluaron los expedientes clínicos electrónicos completos de 100 pacientes con diagnóstico de NT durante el período de abril de 2010 a mayo de 2020. Intencionalmente se buscaron síntomas autonómicos en éstos y se compararon con los criterios diagnósticos de SUNCT y SUNA de la Clasificación Internacional de las Cefaleas, tercera edición. Se realizaron pruebas de chi cuadrado y posteriormente de regresión bivariada para determinar la asociación entre las variables. Resultados: Se incluyó a 100 pacientes con diagnóstico de NT. Tras la revisión de las manifestaciones clínicas, se encontró a 12 pacientes con síntomas autonómicos y se compararon con los criterios diagnósticos de SUNCT y SUNA. Estos no cumplieron los criterios absolutos para ser diagnosticados con las enfermedades previamente mencionadas; sin embargo, cumplieron las características del espectro de cefaleas trigeminoautonómicas. Conclusión: La NT es una entidad dolorosa y frecuente que puede presentar síntomas autonómicos, y es importante pensar en diagnósticos diferenciales, como la SUNCT y la SUNA, para la identificación y el tratamiento correctos.(AU)

Objective: Identify the number of cases with a possible diagnosis of short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) or short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA) in patients with a previous diagnosis of Trigeminal Neuralgia (TN) at the Neurology Service of the National Medical Center 20 de Noviembre. This will confirm that these trigeminal-autonomic cephalalgias should be ruled out and considered as differential diagnoses of trigeminal neuralgia. Patients and methods: Cross-sectional and retrospective study. The complete electronic medical records of 100 patients with a diagnosis of TN were evaluated during the period from April 2010 to May 2020. Autonomic symptoms were intentionally searched for in these patients and compared with the diagnostic criteria of SUNCT and SUNA of the 3rd edition of the International Classification of Headache Disorders. Chi-square tests and subsequent bivariate regression were performed to determine the association between variables. Results: One hundred patients with a diagnosis of TN were included. After reviewing the clinical manifestations, 12 patients with autonomic symptoms were found and compared with the diagnostic criteria of SUNCT and SUNA. However, they did not meet the absolute criteria to be diagnosed with the previously mentioned diseases, nor to be ruled out. Conclusions: TN is a painful and frequent entity that can present with autonomic symptoms, therefore making it important to identify SUNCT and SUNA as differential diagnoses, to recognize them and treat them appropriately.(AU)

[Dolichoectasia of the basilar artery caused by cystic medial degeneration, as a cause of neurovascular conflict with damage to the trigeminal, facial and vestibulocochlear nerves]. / Dolikhoektaziya bazilyarnoi arterii, obuslovlennaya kistoznoi medial'noi degeneratsiei, kak prichina neirovaskulyarnogo konflikta s porazheniem troinichnogo, litsevogo i vestibulokokhlearnogo nervov.

Cystic medial degeneration (Gsell-Erdheim syndrome, cystic medial necrosis) is considered to be a nonspecific histological manifestation of a group of diseases characterized by degenerative changes in the media, affecting primarily the aorta and adjacent branches, which leads to destruction of the vessel wall, followed by its expansion and, possibly, rupture. The authors describe a case of a 65-year-old female patient with a neurovascular conflict of the three cranial nerves with dolichoectatic basilar artery due to cystic medial degeneration. As a result, the patient has clinical manifestations in the form of hemifacial spasm, trigeminal neuralgia and vestibular paroxysmia. Data from instrumental studies and treatment provided are presented. Neurovascular conflict can be identified in various diseases and is characterized by the complex etiology. The most common clinical manifestations of neurovascular conflict are trigeminal neuralgia, hemifacial spasm, glossopharyngeal neuralgia, and vestibular paroxysmia.

Fully endoscopic microvascular decompression for the treatment of hemifacial spasm, trigeminal neuralgia, and glossopharyngeal neuralgia: a retrospective study.

BACKGROUND: Microvascular decompression (MVD) is already the preferred surgical treatment for medically refractory neurovascular compression syndromes (NVC) such as hemifacial spasm (HFS), trigeminal neuralgia (TN), and glossopharyngeal neuralgia (GPN). Endoscopy has significantly advanced surgery and provides enhanced visualization of MVD. The aim of this study is to analyze the efficacy and safety of fully endoscopic microvascular decompression (E-MVD) for the treatment of HFS, TN, and GPN, as well as to present our initial experience. MATERIALS AND METHODS: This retrospective case series investigated fully E-MVD performed in 248 patients (123 patients with HFS, 115 patients with TN, and 10 patients with GPN ) from December 2008 to October 2021 at a single institution. The operation duration, clinical outcomes, responsible vessels, intra- and postoperative complications, and recurrences were recorded. Preoperative and immediate postoperative magnetic resonance imaging (MRI) and computerized tomography (CT) were performed for imageological evaluation. The Shorr grading and Barrow Neurological Institute (BNI) pain score were used to evaluate clinical outcomes. The efficacy, safety, and risk factors related to the recurrence of the operation were retrospectively analysed, and the surgical techniques of fully E-MVD were summarised. RESULTS: A total of 248 patients (103 males) met the inclusion criteria and underwent fully E-MVD were retrospectively studied. The effective rate of 123 patients with HFS was 99.1%, of which 113 cases were completely relieved and 9 cases were significantly relieved. The effective rate of 115 patients with TN was 98.9%, of which 105 cases had completely pain relieved after surgery, 5 cases had significant pain relieved, 4 cases had partial pain relieved but still needed to be controlled by medication. The effective rate of 10 patients with GPN was 100%, 10 cases of GPN were completely relieved after surgery. As for complications, temporary facial numbness occurred in 4 cases, temporary hearing loss in 5 cases, dizziness with frequent nausea and vomiting in 8 cases, headache in 12 cases, and no cerebral hemorrhage, intracranial infection, and other complications occurred. Follow-up ranged from 3 to 42 months, with a mean of 18.6 ± 3.3 months. There were 4 cases of recurrence of HFS and 11 cases of recurrence of TN. The other effective patients had no recurrence or worsening of postoperative symptoms. The cerebellopontine angle (CPA) area ratio (healthy/affected side), the length of disease duration, and the type of responsible vessels are the risk factors related to the recurrence of HFS, TN, and GPN treated by fully E-MVD. CONCLUSIONS: In this retrospective study, our results suggest that the fully E-MVD for the treatment of NVC such as HFS, TN, and GPN, is a safe and effective surgical method. Fully E-MVD for the treatment of NVC has advantages and techniques not available with microscopic MVD, which may reduce the incidence of surgical complications while improving the curative effect and reducing the recurrence rate.

[A rare cause of headache; case report of trigeminal neuralgia concomitant with idiopathic intracranial hypertension]. / Nadir bir bas agrisi nedeni; trigeminal nevralji ve idiyopatik intrakraniyal hipertansiyon birlikteligi: Olgu sunumu.

Trigeminal neuralgia (TN) is the condition of sudden, usually unilateral, very short-lasting, stinging, and recurrent pain in the distribution area of one or more branches of the trigeminal nerve. Idiopathic intracranial hypertension (IIH) is an increase in intracranial pressure associated with normal cerebrospinal fluid composition that is not due to a secondary cause. Although not frequent, the association of IIH and TN has also been reported. We aimed to present a rare case report in which TN is concomitant with IIH. A 56-year-old female patient was admitted to our clinic with the complaint of jabbing pain that may feel like an electrical shock on the right side of her face. In the patient's history, she was diagnosed with TN 8 years ago. She had a lightning-flashing pain in the area corresponding to the right mandibular nerve dermatome. Her pain attacks lasted 1-2 min, and recurring 15-20 times during the day. In the CISS sequence cranial MRI, bilateral perioptic CSF distance showed mild prominence, prominence in Meckel caves, and empty sella appearance features. These findings were found to be compatible with intracranial hypertension. As a result,based on these findings, the patient was diagnosed with TN or trigeminal neuropathy accompanying IIH. While patients diagnosed with TN may be associated with IIH, also trigeminal nerve may be affected, although not as much as other cranial nerves in patients with a diagnosis of IIH. The use of cranial MRI may prevent an additional pathology to be missed.

A Patient with Refractory Trigeminal Neuralgia was Referred for Suspected Odontogenic Pain.

Chronic pain of the face with a sudden, unilateral, and electric shock-like pain in the distribution of the trigeminal nerve is known as Trigeminal neuralgia (TN). This case report presents a patient with TN symptoms, along with concomitant tooth pain. The diagnostic process and management of the patient are discussed, emphasizing the importance of interdisciplinary collaboration for optimal patient care.

Diagnostic Value of Blink Reflex Combined with Trigeminal Somatosensory Evoked Potential in Trigeminal Neuralgia.

Objective: To explore the diagnostic value of blink reflex combined with trigeminal somatosensory evoked potential (TSEP) in trigeminal neuralgia. Methods: A total of 147 patients with trigeminal neuralgia were enrolled as the research objects between February 2022 and February 2023. After admission, all underwent blink reflex on affected/healthy sides and TSEP examinations. The diagnostic value of the blink reflex combined with TSEP was analyzed. Results: The latency of R1, R2, and R2' waves (refers to the different nerve signal waveforms that are recorded when a facial nerve conduction speed test is performed) on the affected side was significantly longer than that on the healthy side (t = 26.324, 18.391, 20.801,Ps < .001), and latency of W1, W2 and W3 waves was also significantly longer than that on the healthy side (t = 16.045, 10.814, 10.349, P < .001). The results of Pearson correlation analysis showed that the latency of R1, W1, W2, and W3 waves was positively correlated with the VAS score (r = 0.539, 0.611, 0.577, 0.586, P < .001). The results of receiver operating characteristic (ROC) curves analysis showed that area under the curve (AUC) values of R1, R2, R2', W1, W2, and W3 waves latency on the affected side in the diagnosis of trigeminal neuralgia were 0.753, 0.634, 0.651, 0.748, 0.756 and 0.736, respectively. The AUC of combined detection was 0.926, significantly greater than that of the single index (P < .001). Conclusion: Blink reflex combined with TSEP monitoring can improve the diagnostic value of trigeminal neuralgia, and the latency is related to pain.

Persisting facial nerve palsy or trigeminal neuralgia - red flags for perineural spread of head and neck cutaneous squamous cell carcinoma (HNcSCC).

BACKGROUND: Perineural spread (PNS) of head and neck cutaneous squamous cell carcinoma (HNcSCC) is a unique diagnostic challenge, presenting with insidious trigeminal (CN V) or facial nerve (CN VII) neuropathies without clinically discernible primary masses. These patients are often sub-optimally investigated and misdiagnosed as Bell's palsy or trigeminal neuralgia. This case series highlights the red flags in history and pitfalls that lead to delays to diagnosis and treatment. METHODS: A retrospective case series of 19 consecutive patients with complete clinical histories with HNcSCC PNS without an obvious cutaneous primary lesion at time of presentation to a quaternary head and neck centre in Australia were identified and included for analysis. RESULTS: Fifteen had CN VII PNS, 17 had CN V PNS, and 13 had both. The overall median symptom-to-diagnosis time was 12-months (IQR-15 months). Eight patients had CN VII PNS and described progressive segmental facial nerve palsy with a median symptom-to-diagnosis time of 9-months (IQR-11.75 months). Eleven patients had primary CN V PNS and described well localized parathesia, formication or neuralgia with a median symptom-to-diagnosis time of 19-months (IQR 27.5 months). CONCLUSION: PNS is often mistaken for benign cranial nerve dysfunction with delays in diagnosis worsening prognosis. Red flags such as progressive CN VII palsy or persistent CN V paraesthesia, numbness, formication or pain, particularly in the presence of immuno-compromise and/or a history of facial actinopathy should raise suspicion for PNS. Gadolinium-enhanced MR Neurography should be obtained expediently in patients with persistent/progressive CN V/CN VII palsies in patients with red flags, with low threshold for referral to a Head and Neck Surgeon.
