    Streszczenie angielskie: The purpose of the study was to present a modern classification and discuss the treatment of midfacial fractures in children. From the beginning of 1 January 1998 to 31 October 2000, 147 children were treated for different craniofacial fractures. Among them 28 patients (19 p.c.) had extensive midfacial fractures complicated by impaired vision and/or CNS dysfunction and were treated surgically. The fractures were divided into: zygomaticoorbital (1 pt) and zygomatico-orbito-maxillary (5 pts), isolated orbital wall fractures (14 pts) and naso-orbital dislocations (2 pts), upper facial portion dislocations (2 pts) and fronto-naso-orbital (2 pts) or cranio-orbital fractures (2 pts). Clinical examination revealed mainly dysfunction of facial morphology and aesthetics (enophthalmos, telecanthus), CSF leakage, impairment of vision and restricted eyeball movements. Ophthalmological, neurological and radiological (Waters view, CT, NMR) examinations were performed in all cases. The treatment consisted of bone repositioning, reconstruction with autologus bone grafts and three-dimensional stabilisation using titanium plates. Twenty-three pts were operated on before and 5 pts after 7th day after trauma. The restoration of normal facial morphology was achieved in 26 patients. In 2 cases it was imposisible because of the destruction of soft tissue and an extremely extensive bony trauma. Better reposition of bony fragments, prompt healing and better final results were achieved in patients operated before day 7 after trauma. Achieving good results in midfacial fractures requires prompt...

    Streszczenie angielskie: The purpose of the study was to modify the method of Bone Morphogenetic Protein (BMP) extraction from bovine bones, estimate the osteoinductive potential of the extracted protein fractions in relation to the degree of protein purity and to test collagen formed in porous discs as a carrier. It was required before BMP application in reconstructive surgery in children. Material and method: BMP preparation from bovine bones was conducted according to a modification of Luyten's method. Three fractions of different degree of purity - demineralised bone matrix "M", extract "E", and fraction after hydroxyapatite column "HP" - were tested for their osteoinductive potential. They were implanted on a collagen carrier into the right rat femoral muscle pouch. Controls were implanted in the same way in the left muscle pouch. The discs were removed after 3 and 6 weeks and tested for alkaline phosphatase activity, a marker of new bone formation. Results: Out of the 10 animals used for testing the osteoinductive potential of matrix fraction, 7 results were positive and 3 negative. In the case of the extract fraction, the analysis was conducted for 3 weeks on 9 rats and 6 weeks on 13 rats. Six and 11 positive results were obtained, respectively. In the HP group 5 animals were observed for 3 weeks (3 positive, 2 negative) and 10 animals for 6 weeks (7 positive, 3 negative). In the case of the extract, the differences in alkaline phosphatase activity after 6 weeks were statistically significant (p ó 0.05) compared to controls. In the other groups, a positive tendency was observed...
