Burs, Surgical, Middle Ear, Cutting
Definition : Middle-ear surgical burs designed for cutting and removal of tissue. These burs typically consist of a shank made of steel or tungsten carbide with a well-differentiated working head with an appropriate shape (e.g., cone, tapered, round) and size on the distal end; a tapered, notched, or elongated proximal end to fit into the rotary device; and a neck that connects the shank to the working part. Cutting middle-ear burs are used in a variety of procedures (e.g., repair of the middle-ear ossicles, stapedectomy); they are usually intended for reuse after sterilization, but disposable (single use) devices are available.
