Summary:The foramen's complex shape, its formation by two bones, and the numerous nerves and venous channels that pass through it further compound its anatomy. Introduction Jugular foramen lesions are among the major complications of skull base surgery. orphological variations in the structure are pertinent during interpretation of skull base radiographs and in surgical procedures within the foramen. The jugular foramen, sometimes referred to as the posterior foramen lacerum, is situated in the floor of the posterior fossa posterolateral to the carotid canal, between the petrous temporal bone and the occipital bone. The contents of the jugular foramen are conventionally divided into the smaller pars nervosa, situated anteromedially, and the larger pars vascularis that is posterolateral, although this terminology is misleading as both contain vascular and neural structures. The jugular foramen transmits the internal jugular vein, inferior petrosal sinus, meningeal branch of ascending pharyngeal artery, glossopharyngeal, vagus and spinal accessory nerves. The jugular foramen is difficult to understand and to access surgically; It is difficult to conceptualize because it varies in size and shape in different crania, from side to side in the same cranium, from its intracranial to extracranial end in the same foramen, because of its complex irregular shape, its curved course, its formation by two bones, and the numerous nerves and venous channels that pass through it. Pathological processes affecting the jugular foramen include intracranial meningiomas, paragangliomas, schwannomas, metastatic lesions and infiltrative inflammatory processes from surrounding structures such as the middle ear [8].
