[Tympanosclerosis (author's transl)].

With a new method--that is embedding non-decalcified tissue in Methylmethacrylat and then slicing it--the patho-histological phenomenon of the tympanosclerosis can be demonstrated with 4 patients on account of the material acquired with the tympanoplasties showing rare localisations (such as stapedial tendon, mastoidale). According to our experiences (42 cases) tympanosclerosis is mainly to be found in female patients not older than 40 years. The genesis of the tympanosclerosis and its reparation through surgical techniques are discussed.
