Long wooden levers have beenused, and also screw-gags, but it is the depression of the jawwhich is the first and most important movement; and unless thiscan be carried out, elevation is of little use. In ancient cases, re-duction may be tried up to twelve months, for if efforts to reducefail, the breaking of adhesions will improve mobility, and one sidemay be tried at a time. In old unreduced dislocations, should greatdistress be experienced, free excision of the condyle should be prac-tised, or division of the ramus of the jaw below the fixed parts. After reduction of a dislocation of the jaw, the ordinary bandageshould be carefully applied, and used for at least a month; andafter this the patient should be cautioned against any incautiousmovement of the jaw, as yawning, which may reproduce displace-ment, unless the chin be
