[Preliminary results of the use of resorbable plates and screws in craniofacial surgery].
In ten patients with craniosynostoses resorbable plates and screws (Lactosorb) consisting of poly-L-lactic acid (82%) and poly-glycolic acid (18%) were used to stabilize the segments after frontoorbital advancement. As our experience increased, an exact adaptation of the plates and simple handling proved to be possible. The plates were stable enough to retain a favorable functional and aesthetic result after redraping the soft tissue envelope. In one patient with Chotzen's syndrome the intended use of the resorbable material was abandoned: the thin osseous structures did not offer enough primary stability to the high pitch of the screws. During an observation period of up to 21 months no infection, exposure, instability or dislocation was observed. The clinical use of the resorbable material in frontoorbital advancement proved to be a stable method of segment fixation if the bone was of sufficient thickness. These promising preliminary results will have to observed in a larger group and over a longer period of time.
