 HORIGUCHI reports the result of fenestration operations which he performed on two patients who suffered a marked degree of conductive deafness the effects of bilateral radical mastoidectomy perforthed 10 years previously. For 10 days fmmediateiy after the operation no improvement of hearing was observable but, thereafter, in about a period of 1 month one patient showed improvement on the average of 35 db and the other of 15 decibels. The fenestration in these cases was performed through the bony depression of the old mastoidectomy scar and the author places a particular emphasis on the advantage of making use of such deformities in similar cases.
