Burs, Surgical, Middle Ear, Cutting, Mastoid
Definition : Middle-ear surgical burs designed for removal of the mastoid bone. 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) 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. Mastoid burs are mainly used in the removal of bone from the mastoid process (mastoidectomy); they are also used in procedures intended for dissection of the facial nerve through the mastoid.
