[Microsurgical anatomy of the area of the superior orbital fissure].

The microsurgical anatomy of the upper rima palpebrarum region was studied in 7 specimens of the base of the skull. The basic indicators in preparing specimens of the upper rime palpebrarum region are the upper and lower tendons of the lateral rectus, the upper orbital vein, the frontal and trochlear nerves. These indicators allow one to dissect cavernous sinusal formations to the rear and orbital formations to the front.
