[Basic studies of ultrasonic surgery. III. Histomorphologic changes in various tissues following exposure to ultrasound].
Absorption of ultrasound leads to reversible or irreversible changes in biological tissues in dependence on the sound intensity. The ultrasound causes under appointed conditions in skin, muscles, vessels, nerve tissue, and bone histopathological changes in a different scale which must be observed in the ultrasonic surgery. 200 tissue specimens from 40 guinea pigs were taken from defined localisations after an ample ultrasound exposition and were evaluated microscopically by hematoxylin-eosin staining technique. Skin and vessels showed very vehement reactions. Intact osseous tissue reacted with periosteal callus formation. Practical conclusions can be draws for the ultrasonic surgery by the discussion on histopathological changes.
