The same instruments used for middle ear surgery should be available for temporal bone preparation. A small set of instruments is advisable. This should contain different forceps, a sickle knife, straight and angled round elevator, needle, micro perforator, 0.6-mm angled-hook, curette, and different sizes of diamond and cutting burrs. More delicate instruments for special procedures should be provided on demand by the instructor. Suction and irrigation are mandatory.
