Local tissue effects of surface-applied ENT drugs.

Local tissue effects caused by a selected group of topically applied ENT-drugs are analysed. By means of a testing system consisting of vital mircoscopy, infrared thermography and microangiography applied to hamsters and rabbits, an evaluation of the varying degree of tissue injury is made. According to the degree of tissue damage the tested substance could be graded in three groups (I-III). The drugs belonging to group I show fairly little microcirculatory disturbance, while those belonging to group III cause tissue necrosis. Our conclusion is that topically applied drugs should be used with caution, especially on previously injured tissues.

Preformed autologous ossicles. Experimental studies.

On the basis of earlier experimental investigations concerning autogenous bone transplants a project is going on with the view to have a patient to create his own bone graft suitable for being used in reconstructive surgery of the middle ear. This theory was tested in 6 rabbits and 6 dogs where a titanium form was installed in the proximal tibial metaphysis. The healing time was 6-8 months. After extraction histologic examination of the facsimile showed that it consisted of an outer form-giving thin layer ocal bone and a system of spongious bone surrounded by marrow with haemopoetic cells. Microradiologic analyses revealed a well mineralized trabecular bone tissue. By means of microangiography a microvascular architecture with a mature appearance could be demonstrated.
