Background: The efficacy and safety of radiosurgery led to paradigm shift in the management of cavernous sinus meningiomas. Nevertheless, patients are still significantly affected by cranial nerve deficits related to the mass effect of these tumors. Our management strategy involves the combination of a functional surgical decompression followed by radiation therapy.Methods: We reviewed a single institution's cohort of patients who underwent endoscopic endonasal decompression (EED) for symptomatic meningiomas primarily involving the cavernous sinus (CS) from 2010 to 2016. The preoperative neuro-ophthalmological exam was compared to the 1- and 6-month postoperative exams. The patient's length of hospital stay, complications, and radiological and clinical follow-up were noted.Results: A total of 17 patients underwent EED for CS meningiomas that fit our radiological criteria. The final outcome at the 6-month visit showed five patients (62.5%) with normalization of deficit and three patients (37.5%) with partial improvement of the CNII deficit. Out of the 12 patients who had cavernous sinus cranial nerves (CSCN) deficits, the final outcome at the 6-month visit showed four patients (33.33%) with normalization of deficit, seven patients (58.3%) with partial improvement, and one patient (8.33%) with no improvement. There were no intraoperative complications.Conclusion: The EED for CS meningiomas is a valuable technique when addressing acute/subacute CNII and CSCN deficits. This conservative surgical approach showed good functional outcomes, low morbidity, and low complication rates. However, it does not exempt the need for radiosurgery/radiation therapy for control of tumor growth.

Inovações técnicas e tecnológicas têm liderado a expansão das indicações de uso das abordagens endoscópicas endonasais para a extirpação de lesões malignas do trato nasossinusal e base do crânio. OBJETIVO: Analisar criticamente a literatura disponível sobre o uso de abordagens endoscópicas endonasais incluindo indicações, limitações, técnicas cirúrgicas, desfecho oncológico e qualidade de vida. MÉTODO: Várias técnicas endoscópicas endonasais foram analisadas segundo a origem e extensão local das lesões malignas nasossinusais e da base do crânio, incluindo a porção anterior da base do crânio, nasofaringe, clívus e fossa infratemporal. A literatura disponível foi também avaliada em função dos desfechos. CONCLUSÃO: As abordagens endoscópicas endonasais são parte integrante do arsenal terapêutico desenvolvido para abordar neoplasias malignas do trato nasossinusais e da base do crânio. Em casos adequadamente selecionados, esta abordagem produz resultados oncológicos semelhantes com menor morbidade do que as abordagens abertas tradicionais. Não obstante, abordagens minimamente invasivas devem ser consideradas como complemento às abordagens abertas estabelecidas, ainda necessárias na maioria dos tumores mais avançados.

Introduction Various lateral and anterior approaches to access the infratemporal fossa (ITF) have been described. We provide our observations regarding the endoscopic transpterygoid and preauricular subtemporal approaches, listing their respective advantages and limitations through cadaveric dissection. Methods A cadaver study was performed on five adult specimens. An endoscopic transpterygoid approach to the ITF was completed bilaterally in three specimens, and an open preauricular ITF approach was performed bilaterally in two specimens. Results After completing the cadaveric dissections, we studied differences between the endoscopic transpterygoid approach and open preauricular subtemporal approaches in regard to exposure and ease of dissection of different structures in the ITF. Conclusions In comparison with a lateral approach, the endonasal endoscopic transpterygoid approach provides better visualization and more direct exposure of median structures such as the nasopharynx, eustachian tube, sella, and clivus. We concluded that the endoscopic transpterygoid approach can be utilized to resect benign lesions and some select group of malignancies involving the infratemporal and middle cranial fossae. Open approaches continue to play an important role, especially in the resection of extensive malignant tumors extending to these regions. [ABSTRACT FROM AUTHOR]

BACKGROUND: Trigeminal sensory neuropathy (TSN) describes a heterogeneous group of disorders manifesting as facial numbness. OBJECTIVE: We report the case of a patient who had TSN associated with contact dermatitis due to Anthurium sp. METHOD/RESULTS: A 21-year-old female patient developed left hemifacial contact dermatitis after exposure to the anthurium plant. The patient had paresthesias and pain in the V2 and V3 divisions of the left trigeminal nerve. Eight days after its onset the dermatitis resolved, but numbness developed in the V2 and V3 divisions of the left trigeminal nerve. Cranial CT scan and MRI, as well as CSF and extensive work-up exams, were normal. After one month the symptoms disappeared completely. CONCLUSION: Anthurium sp, an indoor ornamental plant that contains calcium oxalate crystals, and can causes contact dermatitis. To our knowledge, this is the first report associating TSN with contact dermatitis due to Anthurium sp.INTRODUÇÃO: A neuropatia trigeminal sensitiva (NTS) representa um grupo heterogêneo de doenças, cuja manifestação clínica é a presença de dormência na região facial. OBJETIVO: Relatamos o caso de paciente que apresenta NTS associada com dermatite de contato (DC) devido à planta Anthurium sp. MÉTODO/RESULTADOS: Uma paciente com 21 anos desenvolveu DC na região hemi-facial esquerda, após exposição à planta Anthurium sp. Após a resolução do quadro de dermatite, a referida paciente apresentou dormência e parestesias no território do segundo e terceiro ramos do nervo trigêmeo esquerdo. Um mês após o início do quadro houve resolução completa dos sintomas. CONCLUSÃO: O Anthurium é uma planta ornamental que contém cristas de oxalato de cálcio, que podem causar DC. Para o nosso conhecimento este é o primeiro relato associando NTS e dermatite de contato devido à exposição ao Anthurium sp.
