Polydioxanone (PDS) sheets are commonly used in the treatment of orbital wall fractures. A potential drawback of PDS is that it may be difficult to adapt to the anatomy of the orbital walls. Therefore a study was conceived to test the feasibility of preforming PDS sheets.
PDS sheet material was water-heated and preformed using a template based on a statistical anatomical model. Then the deformed sheet was cooled, stored and compared to the original model to investigate post-deformation changes.
PDS sheet material could easily be deformed using a mould. No significant post-cooling shape changes were noticed.
PDS sheet material can be preformed into complex geometric shapes. This could be a benefit in the treatment of orbital wall fractures.
聚二氧杂环己酮（PDS）片常用于治疗眼眶壁骨折。PDS 的一个潜在缺点是它可能难以适应眼眶壁的解剖结构。因此，进行了一项研究来测试预成型 PDS 片的可行性。
将 PDS 片材料用水加热，并使用基于统计解剖模型的模板进行预成型。然后将变形的片材冷却、储存，并与原始模型进行比较，以研究变形后的变化。
PDS 片材可以很容易地用模具变形。冷却后没有发现明显的形状变化。
PDS 片材可以预成型为复杂的几何形状。这在治疗眼眶壁骨折方面可能是一个优势。
