Objetivo: Desenvolver um estudo morfométrico da corticotomia realizada na amigdalohipocampectomia seletiva dos acessos transsilviano, trans-giro temporal médio (trans-GTM) e subtemporal até o centro do corpo amigdaloide. Métodos: Quarenta cortes coronais de cérebros humanos, cedidos pelo Departamento de Anatomia da Universidade Federal do Paraná foram processados por meio da técnica histoquímica de Mulligan modificada por Barnard, Robert e Brown para posterior mensuração dos acessos por dois métodos diferentes: mensuração manual e digital. A análise estatística dos resultados foi feita por meio do teste t de Student. Resultados: As medidas obtidas dos acessos cirúrgicos foram tabuladas de modo a respeitar o lado do hemisfério cerebral de origem, e os dois métodos de mensuração. Os dados foram expressos em milímetros seguidos do valor calculado da média e desvio-padrão. Conclusão: Os resultados permitiram concluir que as médias obtidas por meio do paquímetro digital, seguidos do desvio-padrão para a abordagem em questão, foram de 17,39±1,72 para a abordagem transsilviana; 34,43±2,77 para a trans-GTM; e de 24,56±2,62 para a subtemporal. As distâncias médias avaliadas por meio do software ImageJ® foram de 17,50±1,70 para a abordagem transsilviana; 34,30±2,94 para a trans-GTM; e de 24,45±2,99 para a subtemporal.
Objective: To develop a morphometric study of transsylvian, trans-middle temporal gyrus (trans-MTG) and subtemporal approaches used in selective amygdalohippocampectomy surgery from the brain cortex to the amygdala’s center. Methods: Forty slices were processed by Mulligan’s histochemistry technique modified by Barnard, Robert and Brown for subsequent measurement by two different methods: manual and digital measurement. The statistical analysis was performed using Student t test. Results: The measurements obtained from surgical approaches, commonly used, were tabulated in order to respect the side of the cerebral hemisphere of origin, and the two measurement methods. Data were expressed in millimeters (mm) followed by the average value and standard deviation. Conclusion: The results showed that the average obtained through the digital caliper, followed by the standard deviation for the approach in question were 17.39±1.72 mm for the transsylvian approach; 34.43±2.77 mm for the trans-MTG; and 24.56±2.62 mm for subtemporal. The average distances evaluated using the ImageJ® software were 17.50±1.70 mm for the transsylvian approach; 34.30±2.94 mm for the trans-MTG; and 24.45±2.99 mm for subtemporal.
