RESUMO
In a prospective study, a new biodegradable osteosynthesis material for the facial skeleton has been used in 27 patients with zygomatic fractures. In the six-month follow-up period, the first ten patients showed clinically and radiologically uneventful healing of bone. There were no implant-related complications. The main advantages of the new material are its malleability when heated, enabling fast adaptation to the bone surface, and the avoidance of a second operation for implant removal.

In a series of five patients with extensive fractures of the orbital floor, we used a biodegradable sheet for bridging of the bony defects. To achieve optimal support of the orbital contents in their anatomically correct position, we fixed the sheet with at least two resorbable screws to the infraorbital rim. This new technique appears to be superior to conventional methods because it offers reproducible results without the need for secondary interventions.

The stable osteosynthesis of mandibular fractures with the modified lag screw (Krenkel) has proven superior to conventional lag screws in theoretical models and clinical use. Compared to osteosynthesis with plate systems, the lag screw technique is more difficult to learn for the unexperienced, but the reduction of fragments under compression with a lag screw and the stabilisation of lower jaw rotation with an additional short miniplate in our experience has proven successful in clinical use.
