Let the lower jaw be now brought into perfect contact with the upper one, and not separated from it during the first few days after the injury, except so far as may be necessary for the admission of nourishing broths. Should a tooth have been lost, the space which it occupied will furnish, without disturbing the bone, an opening for the conveyance of nourishment to the patient. Let talking, laughing, and every thing that might produce a separation between the body of the bone and the condyle, be carefully avoided. The further treatment of the accident should be such as is generally applicable to all fractures of bones, and need not be at present particularly detailed. The following cases, reported by citizen Giraud, second surgeon to the Hotel-Dieu, will confirm the advantages of this mode of treatment. CASE I. Margaret Bessonet, aged thirty-four, was admitted into the hospital on the 10th of May, 1791. On the preceding day she had received a violent fall on her chin: a severe pain, and a preternatural mobility in the left side of the jaw, had been the immediate consequences of the accident: from these symptoms, taken in conjunction with those formerly mentioned (3), Desault discovered that a fracture of the condyle existed, which he reduced and supported in the usual manner (7). After being somewhat uneasy during the first few days, the patient became reconciled to the action of the bandage, which, by inattention, had been two or three times disturbed and put out of order, but which, by being carefully reapplied, and aided by the necessary precautions (8), restored to the bone its natural form and solidity, by the thirtieth day, and on the thirty-sixth the patient was discharged perfectly cured. The only inconvenience she experienced, was a slight difficulty in the motions of the jaw, an effect naturally resulting from the long continued inactivity of the muscles, but which was soon removed by means of exercise. CASE II. Claudius Laurat, aged twenty-seven, fell as he was carrying a heavy burden. In his fall his chin struck with violence against a beam that lay in his way. In an instant he experienced a sharp pain in his right temple, and found it almost impossible to move his jaw. Two hours afterwards a considerable swelling appeared in the part, extending from the angle of the jaw above the ear. The patient was admitted into the Hotel-Dieu, where the circumstances of the fall and the symptoms that followed, gave satisfactory evidence of a fracture of the condyle. It was reduced and supported as in the preceding case. On the day following, the swelling was removed, doubtless by means of the compression which had been made on it; the other symptoms (3), hitherto scarcely perceptible, became more obvious; the bandage was reapplied, and the disease terminated, in about twenty-nine days, in the same manner with that of case 1.
