Introduction:
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.
Material And Methods:
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.
Results:
PDS sheet material could easily be deformed using a mould. No significant post-cooling shape changes were noticed.
Conclusions:
PDS sheet material can be preformed into complex geometric shapes. This could be a benefit in the treatment of orbital wall fractures.
