Indirect injury to cranial nerves after surgery with Cavitron ultrasonic surgical aspirator (CUSA). Case report

Acta Neurochirurgica volume 89, pages 84–86 (1987)Cite this article

Summary

The Cavitron ultrasonic surgical aspirator (CUSA) was used in a patient with an acoustic nerve tumour. After surgery she presented unilateral palsies of several cranial nerves. The nerve injuries were most likely induced by ultrasonic energy transmitted from the CUSA via the petrous bone. We suggest that when the CUSA is used in such operations care should be taken to avoid contact between the vibrating probe of the CUSA and the petrous bone.
