Lateral Approach For Jugular Foramen Area Structures Of Varying Degrees Of Exposure Of Anatomy

Jugulare foramen located in the inside of the partial ahead of temporal bone’s stem hole, the front is the inferior temporal rock, the back is the occipital neck veins, around sigmoid sinus sinus and. inferior petrosal sinus.The left jugulare foramen smaller than the right’s. Because of their size and shape have different difference in all kinds of skull.The skull of each side is different,the jugulare foramen have different intracranial end and extracranial end, and the shape of jugulare foramen is irregular, because jugulare foramen consist of two different harnpans,it has twists and turns in a skull, adjacent to the structure and many around closely. Many cranial nerve and vascular cavity through, position deep, anatomical structure is complex, the surgery is often difficult to reach, is an important channel of the skull base. Jugulare foramen because of its position to exposed deep and adjacent to the lost that around the many important structure of cranial nerve of cochlea, IX-XI, and internal carotid arteries and veins, vertebral artery and so on.Jugulare When jugulare foramen tumors happen not only affects the nervous and blood vessels, but also to invade surrounding structures, make the surgical resection is huge hard to do.Because in clinical symptoms,jugulare foramen tumors have a vary of characteristics, the tumor growth around each direction, it assault surrounding tissue structure makes lesions more complicated. Although different scholars on the anatomical structure on a large detailed research for clinical work provides the anatomy basis, but for the structure of the complexity and different researchers have different research angle in microscopic anatomy material that insufficient. This topic proposed by the12sides of6chinese adult’s head with wet through simulation side into the specimen and improved access to complete way of jugulare foramen and around the hole structure revealed, to a different way to show the same area into a comparative study of the different structure. Aims is the jugulare foramen area in microscopic anatomy, in order to protect the brain stem auditory and its function, face to retain and group cranial nerve function after preserved and reduce complications, such as the cerebrospinal fluid leakage, under the premise of according to the parts of the tumor growth, size, tumor invasion and range and comprehensive consideration of the patients after hearing status and group cranial nerve function, under the premise of cutting and strive for the whole of the tumor.
