Ever since Rosen successfully revived the attempts at mobilization of the ankylosed stapes in otosclerosis the otologists throughout the world have been working on two problems: to develop more satisfactory methods of mobilization and to prevent the reankylosis of the mobilized stapes. Considerable success has been achieved in this respect by purely surgical-clinical research which was greatly aided by our increasing knowledge of the physiology of the sound-conducting system and furthermore by gross anatomical studies of the oval window niche and the adjacent structures. A serious drawback of this approach to the problem lies, however, in the fact that one does not know exactly what is actually heppening to the structures involved during mobilization or afterwards.

Detailed histological studies of serially sectioned temporal bones with otosclerotic ankylosis of the stapes, together with a careful evaluation of the findings with regard to the chances of surgical mobilization would unquestionably be extremely
