This large powerful rongeur saves a great deal of time in the mastoid operation, since it will morsel hard bone very rapidly. The tip of the mastoid process and the outer table of the mastoid are quickly bitten off. When it is necessary to remove a part of the calvarium entire, this instrument will morsel it with great rapidity and with very little jar. The leverage of the instrument permits the exertion of a tremendous force. The rongeur is strong enough to take out the bone rapidly with a minimum of muscular exertion.
