Ultrasonic aspirator (UA), or the Cavitron Ultrasonic Aspirator (CUSA) as it is commonly referred to, utilizes ultrasonic waves of variable range of frequencies to disintegrate and excise tumours. It is developed as a substitute of bipolar diathermy; a tool commonly employed for coagulation that uses focussed electric current and may damage tissues by virtue of contact, or by the heat that it produces. Over the last 30 years, CUSA has become increasingly popular in several soft tissue surgeries, especially brain and spine tumour resection, as it allows reduction in the use of bipolar diathermy. It is assumed that CUSA improves both surgical safety and clinical outcomes, and also reduces surgical time. Herein the authors have reviewed the available literature on the advantages of CUSA.
