title: Transfrontal cavernous sinus venography. A simple method of selective superficial venous compression.
abstract: The authors describe a simple technique of selective superficial venous compression for transfrontal cavernous sinus venography. Sponge-rubber blocks are positioned at the nasomalar angle and held in place with Velcro, with a second set placed just above the orbit. The blocks are kept in place all during filming, resulting in reproducible opacification of the cavernous sinuses despite changes in the position of the patient's head.
