“…The cause of trigeminal neuralgia is still under discussion, but the compression of the trigeminal nerve by a vascular loop is the most frequent finding during exploration of cerebellar-pontine angle. The pain is usually relieved after microvascular decompression (Gusmão et al, 2003). For treatment of trigeminal neuralgia is used the trans-ovale approach by rhizotomy associated to fluoroscopy to guide a needle puncture to the trigeminal impression (Gusmão et al).…”

“…The electrode is then heated to produce a thermal nerve injury, while the patient is under heavy sedation. This form of percutaneous rhizotomy has the best pain control in the long time, about three quarters of patients pain-free after five years (Gusmão et al, 2003).In conclusion, the anatomical knowledge of the emissary foramens and their clinical implications are important in clinical practice, mainly due to variability in their incidence in the human skull and its relation to the sinuses of the dura mater.

SUMMARY:The recognition of emissary foramens is important not only for understanding the regional neurovascular anatomy, but also to distinguish normal from potentially abnormal structures. Thus, the aim of this study was to review the literature on anatomical and clinical aspects of the mastoid, parietal and sphenoid emissary foramens. It was found that the emissary foramen presents importance in clinical practice because it acts as a route of spread of extracranial infection to the intracranial structures and also possible complications in neurosurgery, due to its influence in the performance of techniques such as radiofrequency rhizotomy for treatment of trigeminal neuralgia. The anatomical knowledge of the emissary foramens is important due to variability in their incidence in the human skull and its relation to the dura mater sinuses. KEYWORDS: Emissary foramens 288less studied by clinical, needs a through approach to avoid interpretation errors during procedures in neurosurgery and clinical dentistry (Sicher & DuBrul, 1977;Gupta et al., 2005;Louis Jr. et al., 2009;Rossi et al., 2010).Considering the importance of knowing the implications of the anatomical variations of the human skull can generate during clinical procedures, the aim of this study was to review the literature on anatomical and clinical aspects of the mastoid, parietal and sphenoid emissary foramens. Literature ReviewMastoid Foramen. The emissary mastoid foramen is located at the mastoid portion of the temporal bone, near to occipitomastoid suture (Fig. 1). This foramen can also appear on the occipitomastoid suture and, if present, transmits an emissary vein to sigmoid sinus. It can occur in single or multiple (Sicher & DuBrul).The mastoid emissary vein may act as another route of spread of infection or tumors originated in the face and infratemporal fossa (Sicher & DuBrul).In addition, the mastoid foramen is considered an anatomical landmark that helps in the differentiation of species and, thus, was verified their importance in forensic anthropology (Reis et al.). It is believed that the adaptation of a bipedal hominid position was associated with anatomical and physiological changes in the venous system of the skull base to adapt to the concomitant changes in intracranial venous blood flow. The pattern of venous drainage of the Australopithecus was based on the occipital vein. In homo sapiens, the volume of this drainage was reduced occurring, thus, the development of new veins. Among these new veins, the emissary mastoid vein led to the emergence of the mastoid foramen in the modern human skull (Falk, 1986).These evolutionary changes have shown that the sigmoid sinus drains into the vertebral venous plexus when is in the upright position and drains into the internal jugular vein when is in the supine position (Goucha et al., 2002). Boyd (1930) found an incidence of 68% of the mastoid foramen in a sample of 1478 skulls of modern human, while Falk obtained a 90% incidence in a sample of 51 skulls of early human. Reis et al., found an inci...

“…A 20-Gauge spinal needle was inserted through the ascending extraoral transoval route guided by lateral incidence fluoroscopy. 4 The introduction pathway started 3 cm lateral to the labial commissure and ascended until the intersection point between the coronal plane 3 cm anterior to the tragus and the sagittal plane of the pupil. After touching the skull base, the needle was directed under fluoroscopy to the foramen ovale, using as reference point the clivus intersection with the petrous pyramid.…”

Percutaneous Treatment of Meckel Cave Arachnoid Cyst: Case Report, Surgical Strategy and Literature Review

et al. 2020

Arachnoid cysts are benign intracranial lesions. They are usually located in the middle fossa, but can be found in other locations. We present a case of symptomatic Meckel cave (MC) arachnoid cyst -a very rare location -and a treatment strategy not elsewhere described before for this condition. A 54-year-old female with trigeminal neuralgia with previous history of radiofrequency rhizotomy treatment 6 years before admission had been experiencing pain recurrence with progression, which required successive increases in carbamazepine dosage. Magnetic Resonance Imaging (MRI) showed dilatation of the right MC with extension to the petrous apex. The lesion was compatible with arachnoid cyst, and due to the worsening of the clinical condition, surgical treatment was chosen. Percutaneous puncture of the cyst through the foramen ovale with injection of intracystic fibrin sealant was performed. The patient woke up from anesthesia with pain improvement and was discharged asymptomatic the next day. After 12 months of follow-up, she remained pain-free. In the literature review, we found only eight cases reported as MC arachnoid cyst. These are likely to progress and become symptomatic owing to their communication with the subarachnoid space and a unidirectional valve mechanism. Pain improvement with this technique is probably secondary to the interruption of these mechanisms. ResumoOs cistos aracnoides são lesões intracranianas benignas. Geralmente estão localizados na fossa média, mas podem ser encontrados em outros locais. Apresentamos um caso de cisto aracnoide sintomático no cavum de Meckel (CM)localização muito rarae uma estratégia de tratamento nunca antes descrita para esta condição.

“…A Neuralgia do Trigêmeo de origem idiopática apresenta uma fisiopatologia complexa, somando-se às diversas manifestações clínicas que estão presentes nos pacientes, desta forma esta patologia torna-se um desafio tanto diagnóstico quanto terapêutico [11]. Na maioria dos casos seu tratamento dá-se por meio de terapias medicamentosas, no entanto a falha ou intolerância a este tipo de tratamento e as chances de recidiva podem ser substituídas por outros tipos de condutas, como os métodos percutâneos de radiocirurgia [12], microdescompressão vascular, rizotomia percutânea trigeminal por radiofrequência (RTRF), rizólise percutânea com glicerol e a microcompressão percutânea com balão [13]. Apesar da diminuição das chances de recidiva, um estudo com 39 pacientes tratados com compressão por balão percutâneo identificou complicações pós-operatórias, como hipoestesia prolongada, fraqueza mastigatória e disfunção gustativa em alguns pacientes [14].…”

Introdução: O núcleo trigeminal espinal recebe axônios sensoriais de todos os outros nervos cranianos envolvidos com sensibilidade da cabeça, suas fibras sensitivas atuam na excitabilidade proprioceptiva, assim como na exteroceptiva da face e parte do crânio. O acometimento deste nervo torna conhecida a mais debilitante forma de neuralgia facial. O quadro álgico instala-se e desaparece de forma súbita e reaparece em diferentes intervalos, que são desencadeados por estímulos não dolorosos. Objetivo: Investigar na literatura, segundo revisão integrativa, informações acerca do tratamento medicamentoso, cirúrgico e fisioterapêutico da neuralgia do trigêmeo (NT). Material e métodos: Foi realizada uma revisão integrativa que utilizou livros das áreas de neurociências, teses de doutorado e artigos coletados nas seguintes bases de dados: Lilacs, Medline e Scielo 2000-2013. Resultados: A amostra final contou com 14 artigos divididos em três temáticas de tratamento para NT: cirúrgico, farmacológico e fisioterapêutico. Conclusão: Vários estudos sobre as formas de tratamento farmacológico e cirúrgico estão disponíveis para assegurar uma melhor qualidade de vida aos portadores de NT. A utilização de métodos conservadores da fisioterapia, tais como a osteopatia, acupuntura, eletroestimulação do nervo e laser de baixa potência, também podem ser opções de tratamento.Palavras-chave: neuralgia do trigêmeo, condutas terapêuticas, fisioterapia.
