FRACTURES OF THE BONES OF THE FACE. 175 The symptoms upon which the diagnosis must be made are deformity,mobility, and crepitus. Unless there is much inflammatory swellingthe deformity, which consists usually in a depression or flattening of thecheek just below the outer half of the eye, can be recognized by sightand touch, and the irregularity of the line of fracture can be readilyfelt on the margin of the orbit, or, if it extends to the malar processof the superior maxillary bone, on the under and anterior surface ofthis process by the finger within the mouth. Mobility and crepitusare perceived more rarely ; the latter can be sometimes produced by themovement of the jaw. Anaesthesia or a sense of formication in the cheek, nose, upper lip,and gum of the corresponding side is sometimes observed, and is due Fig. Fracture of the zvgoma. to an extension of the fracture to the infra-orbital canal and tearing orbruising of the superior maxillary nei-ve. This symptom may be asso-ciated with the extravasation of blood in the posterior part of tlie orbitsuflacient to force the eye forward and showing itself also under theconjunctiva and in the eyelids. Bleeding from the mouth or nose isoccasionally seen as the result of the extension of the fracture throughthe mucous membrane of the mouth or antrum. When the fracture involves the zygomatic arch, and the fragments,as is usually the case, are driven inward, movement of the jaw mav bedifllicult or impossible, either* because the masseter has been injured, orbecause the depressed fragments of the arch are Ibreed against thecoronoid process of the inferior maxilla, or into the tendon o\ tlie tem-poral muscle.
