Transcranial approach to the orbit: microsurgical anatomy.

abstract：OBJECT:The angles of arterial bifurcations are governed by principles of work minimization (optimality principle). This determines the relationship between the angle of a bifurcation and the radii of the vessels. Nevertheless, the model is predicated on an absence of significant communication between these branches. Th...
