| __This program is designed
for teaching the anatomy of the posterior skull base. It is specifically
oriented to transaxial CT images of this region. The anatomy
is presented in two different ways. The first identifies the bones
of the posterior skull base as well as their boundaries. The second
uses large, easily identifiable features to locate important anatomic
structures. One of the most prominent features in this regard is the
petro-occipital fissure, a large gap between the medial border of
the petrous temporal bone and the lateral border of the clivus. The
petro-occipital fissure can be used to "navigate" the skull base since
it lies in close proximity to several important foramina, sutures,
and canals. __Images in this module are 2.5 mm sections of a routine CT scan of the head using a high resolution reconstruction algorithm and bone windows. |
