[The significance of dystrophic changes in traumatic facial nerve paralysis]. / Znacaj distroficnih promena kod traumatskih paraliza licnog zivca.

In 61 animals, after experimental removal of the suprachoroid part, complete section, placement of neurosutures, incomplete section and contusion of the facial nerve in the tympanic and mastoid segment, the analysis of dystrophic changes was performed after a year of follow-up. In all animals, except for control group, the degree of the manifested changes was in the direct correlation with the degree of previous lesion. The studies performed pointed out the great importance of trauma and degenerative changes in evaluation of the functional state and actualization of the problem of an adequate otolaryngological treatment of all forms of the peripheral facial nerve paralysis.

[Pathohistological study on the effect of various methods of osteosynthesis on the osteogenesis in experimental fracture of the lower jaw]. / Patohistoloska proucavanja uticaja nekih metoda osteosinteze na osteogenezu u uslovima eksperimentalne frakture donje vilice.

The lower jaw of 60 dogs was fractured and effects of wire and three variants of chemical osteosynthesis have been followed up concerning validity, course and rapidity of osteogenesis. A wire of 0.4 mm in the diameter was applied in wire osteosynthesis and autopolymerizing acryalte ("Simplex" Galenica) in chemical osteosynthesis with briding of the fracture line interfragmentarily or mixed with bone scrapings. The pathohistological examinations performed 7, 14, 21, 60 and 90 days after the intervention and osteosynthesis employment have shown that there is no difference in validity, course and rapidity of osteogenesis in fractures of the lower jaw under conditions of wire and pure chemical osteosynthesis. Since there is no histochemical obstacles and taking into account advantages of chemical over wire osteosynthesis it should be recommended in fractures of the lower jaw.
