Biomechanics and Biometry of the Anterior Skull Base
INTRODUCTION In the opinion of the famous anatomist Testut, the skull base is similar to a ship. This illustrative image obviously takes into consideration the existence of a bow designed to balance the undulatory movements caused by the C1 – C2 occipital articulations. It’s about the exoskull, which allows through its apophyses the insertion of various muscle groups which ensure the equilibriu...
متن کاملskull base (middle cranial fossa lesions)
anatomy: middle cranial fossa mainly floored by sphenoidal bone and located post. to innominate bone or lesser wing and ant. to temporal bone. main foramens are located in deep part, bilateral to sellae are orbital fissures, optic canals, foramen rotundom, ovale and spinosum, foramen lacerum also meckle cave or trigeminal impression and carotid canal. this fossa is like a butterfly in shape. le...
متن کاملCranial base angulation and growth of the human fetal pharynx.
The upper airway controls the mechanisms of breathing, swallowing, and vocalization. Information on its normal ontogenetic associations is therefore crucial for understanding human speech evolution as well as the developmental etiology of speech abnormalities. Of particular interest to evolutionary morphologists is the proposed structural association between the upper airway and the cranial bas...
متن کاملPreoperative Visualization of Cranial Nerves in Skull Base Tumor Surgery Using Diffusion Tensor Imaging Technology.
AIM To visualize cranial nerves (CNs) using diffusion tensor imaging (DTI) with special parameters. This study also involved the evaluation of preoperative estimates and intraoperative confirmation of the relationship between nerves and tumor by verifying the accuracy of visualization. MATERIAL AND METHODS 3T magnetic resonance imaging scans including 3D-FSPGR, FIESTA, and DTI were used to co...
متن کاملDiffusion tensor technique as a preoperative identification of cranial nerves in skull base tumors
The skull base tumors invariably involve one or more cranial nerves as they grow, first distorting their normal course and then altering their integrity. The use of the high density diffusion tensor imaging technique as a complementary tool permits the identification of cranial nerves in these cases and, in combination with current neurosurgery techniques, it allows for the implementation of a ...
