Technical considerations in powered instrumentation.
This article reviews some of the technical engineering aspects of the soft-tissue shavers and bone-cutting drills. An improved understanding of these principles may allow the practicing surgeon to optimize the desired aggressiveness and precision of the instrument in his or her hands. Powered instrumentation has found extended uses beyond sinus disease, such as submental lipectomy (soft-tissue shaver) and modifying the bony nasal dorsum (bone cutting bur). Changes in drill design to address these and other surgical situations are discussed.
