Flexed cranial base

WebNational Center for Biotechnology Information WebThe patient’s neck is flexed and an “armored endotracheal tube” is used to avoid kinking of the tube during neck flexion. Neck flexion should leave at least two-fingers width between the patient’s chin and chest (thyromental distance). Figure 10: The axillary roll is necessary with the patient in a park-bench position.

WebNov 1, 2006 · Ontogenetic and phylogenetic variations in the cranial base angulation have been widely discussed ; cranial base flexure is associated with humanization and postnatal growth. In non-hominid primates, the flexion of the cranial base occurs when the brain size increases and as the upper and lower face become more ventrally deflected [ 17 ].

Two of the more noteworthy of these changes are the increase in endo-cranial capacity, and the flexion of the cranial base as measured by the sphenoidal angle. Sinanthropus pekinensis and Solo man, for example, differ from the nonhuman anthropoids in having larger brain cases and more flexed cranial bases (among other things).
