Piezosurgery as a further technical adjunct in minimally invasive supraorbital keyhole approach and lateral orbitotomy

One of the problems in neurosurgery is how to perform rapid and effective craniotomies that minimize the risk of injury to underlying eloquent structures. The traditional high-powered pneumatic tools and saws are efficient in terms of speed and penetration, but they can provoke bone necrosis and sometimes damage neurovascular structures. As an alternative, we evaluated the piezoelectric bone scalpel (piezosurgery), a device that potentially allows thinner and more precise bone cutting without lesioning neighboring delicate structures, even in the case of accidental contact.
