Cranial Neuralgias.

OBJECTIVE: The cranial neuralgias are relatively rare, but recognizing these syndromes and distinguishing among them is critical to reducing unnecessary pain and disability for affected patients. Despite their distinctive features, cranial neuralgias may go undiagnosed or misdiagnosed for several years. A notable proportion of cranial neuralgia presentations are due to secondary causes and require targeted treatment. The purpose of this article is to review the diagnosis and management of cranial neuralgias encountered in clinical practice. LATEST DEVELOPMENTS: In 2020, the International Classification of Orofacial Pain was released for the first time. Modeled after the International Classification of Headache Disorders, it includes updated terminology for cranial neuralgias. The underlying pathophysiology of the cranial neuralgias is currently believed to be rooted in both peripheral and central nociceptive systems. In addition, a growing number of familial cases are being identified. Recent therapeutic advancements include a better understanding of how to utilize older therapies and procedures more effectively as well as the development of newer approaches. ESSENTIAL POINTS: Cranial neuralgia syndromes are rare but important to recognize due to their debilitating nature and greater likelihood of having potentially treatable underlying causes. While management options have remained somewhat limited, scientific inquiry is continually advancing the understanding of these syndromes and how best to address them.

Revisión bibliográfica del uso de láser de baja potencia como tratamiento en alteraciones del nervio alveolar inferior en osteotomía sagital de rama / Literature review of the use of low power laser therapy for treating inferior alveolar nerve disorder in sagittal ramus osteotomy

Una de las principales complicaciones al realizar la osteotomía sagital de rama, es la presencia de alteraciones sensitivas que se producen a nivel del nervio alveolar inferior. La parestesia luego de esta técnica reporta una incidencia entre el 85-87 por ciento, de los cuales entre el 0-24 por ciento queda con parestesia permanente. Dentro de los tratamientos utilizados para recuperar las alteraciones sensitivas se encuentra el uso de láser de baja frecuencia; el cual se utiliza para acelerar la recuperación sensitiva y la reparación neuronal, disminuir el dolor y restaurar el funcionamiento normal del nervio injuriado. Los objetivos de esta investigación fueron realizar una revisión bibliográfica sobre los resultados obtenidos en pacientes sometidos a osteotomía sagital de rama que presentaron alteraciones sensitivas y en cuyo tratamiento se utilizó el láser, y crear un protocolo de tratamiento con láser en pacientes sometidos a osteotomía sagital de rama madibular. Se realizó una revisión de artículos entre los años 1990-2010, utilizando buscadores como: EBSCO, Cochcrane, TripDataBase, Medline, Lilacs, Pubmed y Decs, además de una búsqueda en revistas científicas. Los resultados de los artículos seleccionados señalan el efecto beneficioso que conlleva el uso del láser, demostrando su eficacia en la recuperación precoz de la sensibilidad postoperatoria. El uso del láser de baja frecuencia es una alternativa favorable para pacientes con alteraciones sensitivas que fueron sometidos a cirugía sagital de rama, debido a su pronta, mejor y mayor recuperación de la sensibilidad...

A major complication that occurs at the sagittal ramus osteotomy, is the presence of damage occurring at the inferior alveolar nerve. An incidence of paresthesia after this technique reported at 85-87 percent, of which between 0-24 percent are left with permanent paresthesia. Among the treatments used to restore sensitivity is the use of low level laser therapy, which is used to speed recovery and repair sensitive neurons, reduce pain, and restore normal functioning to injured nerve. The aims were to undertake a literature review of empiric research on the results obtained in patients under going sagittal ramus osteotomy, who has sensory disturbances and in wich laser treatment was used, and create a laser treatment protocol in patients undergoing sagittal ramus osteotomy. A review of articles between the years 1990-2010, using search engines such as EBSCO, Cochcrane, Tripdatabase, Medline, Lilacs, Pubmed and Decs. The review also included a search in scientific journals. The results of the reviewed literature showed the beneficial effect of the use of laser, demonstrating its effectiveness in the early recovery of postoperative sensitivity. The use of low level laser therapy is a favorable alternative for patients with sensory impairment who underwent sagittal ramus osteotomy due to its rapid and greater sensitivity recovery...

A dissecção espontânea da artéria carótida interna é evento raro, acometendo principalmente indivíduos em idade produtiva. Como a abordagem precoce e adequada dessa doença determina quase sempre melhora significativa, torna-se evidente a necessidade de ampliar os conhecimentos sobre seus aspectos clínicos, patogênicos e fisiopatológicos, visando o diagnóstico e tratamento precoces, bem como a redução de suas possíveis seqüelas. Pelos motivos expostos, julgamos pertinente relatar o caso de um homem de 46 anos com dissecção espontânea de artéria carótida interna, com manifestações clínicas atípicas dentre as quais ressaltamos a paralisia de nervos cranianos inferiores.

Spontaneous internal carotid artery dissection is a rare event that strikes patients at their productive age. As early intervention frequently determines a significant improvement, it is important to broaden the knowledge of the clinical, pathogenic and pathophysiological aspects of this disease. The objective is making an early diagnosis and treatment to avoid a bad outcome. We report the case of a 46 years-old man with spontaneous carotid artery dissection that had an atypical manifestation characterized by sudden paralysis of lower cranial nerves.

Neuropatía del tercer par craneal secundaria al síndrome de hipotensión intracraneal / Third cranial nerve palsy due to intracranial hypotension syndrome

Introducción. El síndrome de hipotensión intracraneal(SHIC) se caracteriza por cefalea ortostática secundaria ahipovolemia de líquido cefalorraquídeo (LCR). Es frecuenteque curse con paresia de pares craneales (PC) bajos y delVI PC. Sin embargo, la neuropatía del III PC es excepcional.Caso clínico. Hombre de 43 años que consulta por cefaleay visión doble de evolución subaguda y perfil ortostático.En la exploración destaca paresia del III PC izquierdosin afectación pupilar. En la resonancia magnética (RM) craneoespinalse observan hallazgos típicos que confirman lasospecha clínica de SHIC. El estudio del LCR muestra presiónde apertura de 5 cm de agua, leve proteinorraquia (0,63 g/l)y pleocitosis linfocitaria (13 leucocitos/ml). Un traumatismoraquídeo acontecido 3 meses antes de iniciarse la clínicacon demostración de fracturas vertebrales lumbares en tomografíacomputarizada de columna indica el probable origende la fuga de LCR. El cuadro se resolvió con tratamientoconservador en 3 meses. Una RM craneal realizada a los10 meses fue normal.Discusión. La neuropatía del III PC en el contexto delSHIC es una circunstancia excepcional que contribuye a ampliarsu espectro clínico (AU)

Introduction. Intracranial hypotension syndrome (IHS)is clinically defined by orthostatic headache due to cerebrospinalfluid (CSF) hypovolemia. It is frequently associatedwith lower cranial nerve (CN) paresis, especiallythe 6th one. However, neuropathy of the 3rd CN is rare.Case report. A 43 year old man presented with orthostaticheadache and vertical diplopia of gradual onset.Clinical examination detected incomplete, pupil sparingleft third CN palsy. Magnetic resonance imaging (MRI) ofthe brain and spine demonstrated typical abnormalitiesthat confirmed the clinical suspicion of IHS. Lumbarpuncture showed an opening pressure of 5 cm of water.CSF disclosed mild protein elevation (0.63 g/l) and lymphocyticpleocytosis (13 cells/ml). A history of spinaltrauma three months prior to the onset of the symptomsand lumbar fractures identified in a spine computedtomography scan suggested the likely origin of the CSFleak. The symptoms responded to conservative measuresin three months and a cranial MRI performed ten monthslater was normal.Discussion. Third CN palsy is an extremely unusualmanifestation of IHS and contributes to the expansion ofits clinical spectrum (AU)
