[Surgical methods for the correction of malocclusion Angle II/1 with postoperative prosthetic rehabilitation].
The operating methods for Angle class II, 1 are described and a method developed in which a front teeth block segment in the maxilla is raised and palatally tilted. At the same time a front and lateral teeth block segment of the lower jaw is pushed forward and lowered. The method improves the profile as well as occlusion and requires only a minimum of prosthetical care.

Growth influence on tubal function.
The influence of growth on tubal function was studied in 26 children by means of tubal function tests in a pressure chamber and by geometric analysis of lateral cephalograms. Good tubal function coincided with mesoor brachycephalic skeletons, poor tubal function with dolichocephalic morphologic patterns. According to our results, tubal function seems to be strongly influenced by the growth processes of the skull.

The role of matrix vesicles in the pathogenesis of tympanosclerosis.
In a histological and electron microscopical study the authors investigated the pathogenesis of tympanosclerosis. Emphasis was placed on the role of extracellular lysosomes (= matrix lysosomes). The function of such matrix lysosomes is connected with the two-stage degradation of the connective tissue. This system gets out of control in tympanosclerosis. Inflammatory and immunological processes are suggested to be superimposed on this lysosomal action.
