Preliminary experience with ultrasonic aspiration in neurosurgery.
A new instrument utilizing ultrasonic energy to fragment and aspirate normal and pathological tissue has been evaluated for neurosurgical use. The instrument has been tested in several animal models to assess its efficacy and safety. The instrument has been used clinically in 38 cases for removal of meningiomas, acoustic neurinomas, and other tumors. Future modifications and applications are discussed.
