title: The Cavitron ultrasonic aspirator in tumor surgery.
abstract: The CUSA Ultrasonic Surgical System fragments and aspirates a wide spectrum of firm tumors of the central nervous system with little transmitted movement to adjacent normal neural structures. The CUSA system is clearly of limited value in removing extremely calcified or dense fibrous tumors. It lacks primary hemostatic properties, and conventional hemostatic techniques are necessary.
