Objective: To compare the right and left sides of the same skulls as far as the described landmarks are concerned, and establish the craniometric differences between them. Method: We carried out measurements in 50 adult dry human skulls comparing both sides. Results: The sigmoid sinus width at the sinodural angle level was larger on the right side in 78% of the cases and at the level of the digastric notch in 72%. The jugular foramen width was also larger on the right side in 84% of the cases. The sigmoid sinus distance at the level of the digastric notch was larger on the right side in 64% of the cases, and the sigmoid sinus distance at the level of the digastric notch to the jugular foramen was larger on the right side in 70% of the cases. Conclusion: Significant craniometric differences were found between both sides of the same skulls.Keywords: skull base, posterior fossa, jugular foramen, craniometric points, sigmoid sinus. RESUMOObjetivo: Comparar os lados direito e esquerdo no mesmo crânio nos pontos referenciais descritos e definir as diferenças craniométricas entre ambos. Método: Realizamos mensurações em 50 crânios secos de humanos adultos comparando os lados direito e esquerdo. Resultados: Como resultado, obtivemos as medidas da largura do seio sigmóideo na altura do ângulo sinodural maiores no lado direito em 78% dos casos e na altura do ponto digástrico em 72%. A largura do forame jugular foi também maior no lado direito em 84% dos casos. A distância do seio sigmóideo na altura do ângulo sinodural até a altura do ponto digástrico foi maior do lado direito em 64% dos casos, e a distância do seio sigmóideo na altura do ponto digástrico até o forame jugular foi maior do lado direito em 70% dos casos. Conclusão: Diferenças craniométricas significativas foram encontradas entre os dois lados do crânio.Palavras-chave: base do crânio, fossa posterior, forame jugular, pontos craniométricos, seio sigmóideo.The jugular foramen, with its internal and neighboring vital structures, represents a major challenging the treatment of lesions in that region. Knowledge about the anatomy and the microsurgical techniques, associated with knowing the landmarks on the internal and external surfaces of this region mitigate morbidity and improve the prognoses of surgical interventions, preserving nervous and vascular structures.In this paper we report a comparative study of the sigmoid sinus and the jugular foramen using the following structures as key landmarks: the sigmoid sinus sulcus the transition point between the sigmoid sinus sulcus and the transverse sinus (sigmoid/transverse sinus) and the digastric notch in both sides of the same skull. With such measures we tried to create reference points to help surgeons approach the sigmoid sinus region.To establish reference values between the right and left sides for the sigmoid sinus sulcus and the jugular foramen using the transverse/sigmoid sinuses junction point and the digastric notch as landmarks.Assess whether or not there are differences in the values measured...
