Zitowitsch reports twenty cases ofotosclerosis treated with the faradic cur-rent: With one or two exceptions, all the cases showincrease in hearing and decreased tinnitus. Oneelectrode should be introduced into the mouth of theeustachian tube, the other placed between the jawand the mastoid. The treatment should last forthree to five minutes, and be repeated tri-weekly,with as strong a current as can be borne. Dr. Philip D. Kerrison, of New York, writingof otosclerosis, says that the results of treatmentare not encouraging. The prediction of Politzerthat the deafness occurring in the advanced stagesof the disease Avill remain forever beyond the abilityof the otologist to cure, is one which few, at thepresent time, will care to Fig. 118.—Electric Otoscope. OTALGIA. In otalgia, especially after acute inflammations, MECHANICAL MASSAGE, 417 a strongfaradic current, lasting abont three min-utes, is useful. (Urbantscliitscli.) INCISION OP THE MEMBRANA TYMPANI. Ballenger, of Chicago, advocates using the elec-tro-cautery in adhesive non-inflammatory cases, asthe incision remains open longer than when madewith a knife. He gives the following technic: 1. Inject 2 per cent cocaine through the cathe-ter into the middle ear. 2. Use an electrode with a bent shank. 3. Employ sufficient current to instantly raisethe cautery-point to a bright red. 4. Make contact before turning on the current. 5. Keep in contact for one second. The perforation of the membrana tympani wasfirst practiced by Yoltolini. Of late, the galvano-cautery has superseded allother methods of producing artificial petforation ofthe membrana tympani in catarrhal otitis results are so
