Finally, the important anatomicalstructures can be sketched into the cross-section, a pro-cedure which is greatly facilitated by the aid of a goodcross-section anatomy like that of Eyclesheimer, andShoemaker, for example. It is now possible with thesedata to plan the operation and select the incision withreference to surgical and anatomical considerations,. 23.
