Importance of the temporal venous drainage to the petrosal approaches of the skull base

Abstract: Objectives: The temporal venous drainage is essential to the favorable prognosis of the patients whose require subtemporal and petrosal approaches to the skull base. To obtain adequate exposure of the middle and posterior fossae the tentorial split is an important step. The aim of this paper is discuss the anatomical aspects of the venous patterns of the temporal lobe stressing the relevant correlations with the petrosal and tentorial approaches. Methods: The authors review the anatomic, surgical and radiologi… Show more

“…Both patients continued to have symptomatic edema for 3–4 weeks, and one of the patients required a second craniotomy during that time period [ 17 ]. Some authors have stated that meningiomas that interfere with venous drainage are at higher risk for significant cerebral edema following resection, and have recommended that a super-selective angiography be performed prior to resection [ 18 ]. In a retrospective study of 229 patients treated by single session or multisession radiosurgery or stereotactic radiotherapy four variables were associated with likelihood of edema development: tumor volume >4.5 mL, non-basal tumor location, tight brain/tumor interface, and atypical histology.…”

“…É recomendável que cirurgiões de tumores de base de crânio tenham contato contínuo com a microcirurgia vascular, com o intuito de se manterem confortáveis com as dissecções vasculares que se fazem necessárias nestas ressecções tumorais. 1,2,4,6,8,23,32,43,44,55 Fechamento Presente na Abertura O planejamento dos retalhos de pericrânio e de fáscias, preferencialmente pediculados, os retalhos musculares e suas variações, para serem utilizados no fechamento das abordagens, foram programados e executados durante os primeiros passos da abertura. O fechamento de complexas e extensas abordagens da base do crânio é uma etapa fundamental para a redução das fístulas de líquor.…”

“…O adequado fechamento diminui o risco de complicações que podem ser de grande morbidade. [1][2][3][4][5][6][7][8]28,50,[52][53][54][55] Disecção e Exposição Em geral, realizou-se a dissecção das principais estruturas neurovasculares relacionadas à abordagem de cada lesão, antes de se iniciar o trabalho de ressecção tumoral. Este princípio é fundamental para que diminua o risco de lesões inadvertidas de qualquer estrutura deslocada ou envolvida pelo tumor.…”
