THE RESULTS of the radical mastoid operation are not quite satisfactory as far as the conservation of hearing and the cessation of the secretion are concerned. For this reason many modifications of the surgical technique have been suggested, a great number of them being disappointing in the long run.
I feel that the recommendation of effective modifications presupposes an exact knowledge of the microscopic changes in the tympanic cavity and in the antrum resulting from a radical operation. My microscopic material is not large enough to allow final conclusions in this respect; however, it furnishes certain data which may be important for the technique of the operation.
In a previous study1 I examined nine temporal bones from eight patients in whom a radical mastoid operation was performed (in one patient a radical operation was performed on both sides). Since that time three additional cases have been examined by my
