Abstract
Introduction: A high-speed power drilling technique for performing an anterior clinoidectomy has been advocated in all publications on paraclinoid region neurosurgery. The entire shaft of the power drill is exposed in the operative field; thus, all neurovascular structures in proximity to any portion of the full length of the rotating drill bit are at risk for direct mechanical and thermal injury. Ultrasonic bone removal (SONOPET) has been developed to reduce the risk of potential complications of the traditional power drilling technique for anterior clinoidectomy. However, ultrasound-related cranial neuropathies are recognized complications of its use. Other considerations for using this technique include the cost of device acquisition and maintenance.
