Matas test was unable to be carried out because the tumor was so large, extending from the right skull base to the supraclavicular fossa, which made a tangible compression infeasible, while balloon occlusion test proved that a temporary 30 min occlusion of ICA brought about no significant symptoms and signs of neurological or sensorimotor system, preoperative embolization was not routinely carried out.[sup][2] During surgery, the internal jugular vein, vagus nerve, hypoglossal nerve and sympathetic trunk were preserved.
