Zusammenfassung: | The jugular foramina (JF) are bilateral openings situated between the lateral part of the occipital bone and the petrous part of the temporal bones in the human skull. It is a bony canal transmitting neurovascular structures from the posterior cranial fossa through the base of the skull to the carotid space. Since the JF depicts variations in shape, size, height and volume between different racial and gender groups, along with distinctive differences in laterality from its intracranial to extracranial openings, knowledge of the JF may be necessary to understand intracranial pathologies. Therefore, the purpose of this study was to evaluate the morphometric measurements of the jugular foramen. Various morphometric parameters of the JF and its relation to surrounding structures were measured and assessed in 73 dry skull specimens (n=146). Each of the morphometric parameters measured were statistically analyse using SPSS to determine the existence of a possible relationship between the parameters and sex, race, age and laterality. The comparisons of sex and age with the distance between the JF and lateral pterygoid plate and distance between the JF and foramen magnum yielded statistically significant p values of 0.0049 and 0.036, respectively. The results of this study correlated with that of previous studies indicating that measurements regarding the JF are greater on the right side. The provision of morphometric data pertaining to the JF and surrounding structures may assist surgeons and clinicians during operative procedures.

Los foramenes yugulares (FY) son aberturas bilaterales situadas entre la parte lateral del hueso occipital y la porcion petrosa del hueso temporal del craneo humano. Se trata de un canal oseo que da paso a estructuras neurovasculares de la fosa craneal posterior a traves de la base del craneo hasta el espacio carotideo. Ya que el FY representa variaciones en la forma, tamano, altura y volumen entre diferentes grupos raciales y sexo, ademas de las diferencias distintivas en la lateralidad desde sus aperturas intracraneales a las aperturas extracraneales, se hace necesario su conocimiento con el objetivo de comprender las patologias intracraneales. El proposito de este estudio fue evaluar las mediciones morfometricas del FY. Se midieron y evaluaron muestras de 73 craneos secos, bilateralmente (n=146). Se estudiaron varios parametros morfometricos del FY y su relacion con la |
