title: [Experiences with a new bone drill for surgery of the ear and nose (author's transl)].
abstract: Surgical drilling similar to that developed by Kaltenbach and Voigt for bone work on the ear, nose, maxilla, hand and vertebrae can be used at up to 80,000 rev/min without undesirable heat production. Drill-bits with the normal shaft length of 45 mm remain steady at 80,000 rev/min, but drill-bits of 70 mm length sometimes vibrate. The size of drill head and rate of revolution in this respect are related proportionately especially with cutting as opposed to diamond drill-heads. In ear surgery this method is only suitable on certain conditions. In nasal surgery it is useful for the transverse osteotomy with a 45 mm long circular saw.
