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.
在一名患有听神经瘤的患者身上使用了Cavitron超声手术吸引器（CUSA）。术后她出现了多条颅神经的单侧麻痹。神经损伤很可能是由CUSA通过岩骨传递的超声能量引起的。我们建议，当在这类手术中使用CUSA时，应注意避免CUSA的振动探头与岩骨接触。
