title: [Orbital floor reconstruction. Comparison of a new perforated 0.15 mm thick PDS layer with established titanium dynamic mesh].
abstract: BACKGROUND
  For surgical reconstruction of the orbital floor after blow-out fractures, a new perforated PDS (poly-p-dioxanon) foil (0.15 mm thickness) has recently become available. The main target of this prospective and randomized interdisciplinary clinical study was to compare this new PDS foil with the proven titanium dynamic mesh (0.3 mm thickness).
  
  
  METHODS
  Aside from the common diagnostic procedures, an extensive ophthalmologic examination was performed and documented preoperatively (U1), 4 days (U3), 1 month (U4), and 6 months (U5) postoperatively.
  
  
  RESULTS
  In both groups the surgical procedure was tolerated well. The new perforated PDS foil turned out to be easier to handle intraoperatively because of smooth and clean cutting edges. The surgical treatment was well tolerated in all randomized groups. In contrast to the control group, the PDS and TD groups showed postoperatively a slight increase of the preoperative exophthalmos (mean 0.5 mm).
  
  
  CONCLUSIONS
  The new perforated PDS foil is comparable concerning cosmetic and functional aspects. Especially with regard to stability after blow-out fractures, the new perforated PDS foil is equal to titanium dynamic mesh up to 20 mm in diameter. PDS foil is felt to be superior regarding bioresorption and due to the more convenient handling.
