Mason transfixes the nose, after reduction of the frag-ments, with a stout needle, and steadies the pieces with astrip of plaster crossing the bridge of the nose and fast-ened to the ends of the needle. The needle is kept inposition for eight or ten days (Fig. 251). Fig. Masons dressing for fracture of the nasal bones. Profuse hemorrhage sometimes occurs after fracture ofthe nasal bone-, and may require plugging of the nares tocontrol it. Fractures of the nasal bones are usually quitefirmly united in two weeks, and dressings may be dis-pensed with after this time. Fractures of the Malar Bone and Zygoma.—Thesefractures are usually the result of direct force; the dis-placement is upward or backward, and when the zygo-matic arch is broken the fragments from pressure uponthe masseter muscle or on the tendon of the temporal 356 FRACTURES. muscle may interfere with the movements of the lowerjaw in mastication. This displacement is corrected bycutting down upon the fragment and elevating it or bypassing a tenaculum into the fragment and raising displacements may be corrected by pressure andthe application of a compress.
