Tests of hearing are now being used in stapes surgery for (1) the selection of cases; (2) the setting of functional goals for each case operated on; (3) the prediction of results, and (4) the evaluation and reporting of results. In addition, hearing tests have been employed as a guide for the surgeon during the operation.

It is the purpose of this paper to deal with the application of hearing tests to the selection of cases.

Air- and Bone-Conduction Thresholds  It is generally accepted that the relationship between the pure-tone thresholds of hearing by air conduction and by bone conduction, the so-called air-bone gap, is the audiologic basis of case selection for the surgery of otosclerosis. A normal or near-normal threshold by bone conduction in the presence of a significant air-conduction loss is believed to represent the most suitable condition for surgery. Conversely, cases in which the air- and bone-conduction
