BACKGROUND
The results of using resorbable plates and screws (82% polylactic acid and 18% polyglycolic acid) in craniofacial surgery for the correction of craniosynostosis after more than 4 years of experience are presented. Special attention is focussed on the degree of stability and the clinical tissue response to the material employed to answer the question of whether the material is an adequate alternative to titanium.
METHODS
Thirty patients who had been treated with this method for craniosynostoses were examined at regular intervals regarding the shape and stability of the forehead region, visibility and palpability of the plates, and tissue reactions.
RESULTS
The technical handling of the osteosynthesis material proved to be simple and reliable. In one case the bone was not strong enough for the screw pitch. After an observation period of a maximum of 4 years and 1 month, the fixations were stable with no signs of adverse reactions.
DISCUSSION
If the long-term results remain favorable, we consider the use of resorbable material a promising method for the stabilization of segments in craniofacial surgery in children.
背景
本文介绍了在颅面外科手术中使用可吸收板和螺钉（82%聚乳酸和18%聚乙醇酸）矫正颅缝早闭超过4年的经验结果。特别关注稳定性程度以及临床组织对所用材料的反应，以回答该材料是否是钛的合适替代品这一问题。
方法
对30例采用该方法治疗颅缝早闭的患者定期进行检查，观察前额区域的形状和稳定性、板的可视性和可触知性以及组织反应。
结果
骨合成材料的技术操作简单可靠。有1例患者的骨强度不足以承受螺钉间距。经过最长4年1个月的观察期，固定稳定，无不良反应迹象。
讨论
如果长期结果仍然良好，我们认为使用可吸收材料是儿童颅面外科手术中稳定骨段的一种有前景的方法。
