Normal high-resolution computed tomographic (CT) scans of 126 patients were reviewed to define the diameter, height of the bifurcation, and transverse position of the normal basilar artery. The mean diameter of the normal basilar artery is 3.17 mm at the level of the pons. In 92% of normal subjects, the basilar bifurcation is located in the interpeduncular cistern adjacent to the dorsum sellae ...

BACKGROUND Surgery of skull base meningiomas by the lateral supraorbital (LSO) approach requires relaxed brain. Therefore, we assessed combined effects of the elements of neuroanesthesia on neurosurgical conditions during craniotomy. METHODS The anesthesiological and surgical charts of 66 olfactory groove, 73 anterior clinoidal, and 52 tuberculum sellae meningioma patients operated on by the ...

Traccatichthys tuberculum, new species, is herein described from the Jian-Jiang, a coastal river in Guangdong Province, South China. Photo by Bosco P.L. Chan. This new species differs from all other Chinese congeners (i.e., T. pulcher and T. zispi) in interorbital width, caudal-peduncle length, and pectoral-fin length. It, together with T. zispi, lacks the color patterns of the dorsal and anal ...

The role of the cranial base in the emergence of Class III malocclusion is not fully understood. This study determines deformations that contribute to a Class III cranial base morphology, employing thin-plate spline analysis on lateral cephalographs. A total of 73 children of European-American descent aged between 5 and 11 years of age with Class III malocclusion were compared with an equivalen...
