“…Rinna empfiehlt bei größeren Defekten eher Titannetze [63]. Diese sollten allerdings stets in gut vaskularisiertes Gewebe eingebettet sein [69]. Silikon und Teflon werden von diesen Autoren als weitgehend obsolet in der Orbitarekonstruktion betrachtet.…”

Reconstruction materials and techniques for the skull base have undergone rapid developments and differentiation in recent years. While mostly autotransplants, collagens or resorbable alloplastic materials are preferred for duraplasties, pronounced organ-specific differences can be observed IN the reconstruction of hard tissues. The use of polymethylmethacryl bone cement, once wide-spread, has decreased greatly due to the release of toxic monomers. Bony autotransplants are still used primarily for smaller skull-base defects, intraoperatively formable titanium meshes may be also used for larger fronto- or laterobasal reconstructions of bony defects. Defects in visible areas are increasingly closed with preformed titanium or ceramic implants, which are planned and fitted to the individual patient using preoperative CT imaging. At the skull base, this applies especially to reconstructions of the frontal sinus. For extensive reconstructions of the orbita, titanium meshes and non-resorbable plastics have proven valuable, in closing smaller defects especially of the orbital floor, resorbable implants based on Polyglactin 901 are also used.

“…Hinsichtlich PDS -Folie ist das Schrifttum uneinheitlich. Röpke befürwortet PDS bei frischen Defekten [69]. Hingegen beobachtete Baumann [76] bei Einsetzen eines PDS -Implantates als Spätkomplikation einen Enophthalmus mit Rezidiv-Doppelbildern nach Resorption der Folie.…”

“…The literature is inconsistent with respect to PDS ® -Foil. Röpke recommends PDS ® for fresh defects [69]. On the other hand, Baumann [76] observed enophthalmus with recurrent double vision after resorption of the foil as a late complication in the use of a PDS ® implant.…”

Purpose The orbital floor is frequently involved in head trauma. Current evidence on the use of reconstruction materials for orbital floor repair is inconclusive. Accordingly, this study aimed to compare the impact of polydioxanone (PDS) foil thickness on reconstruction of the orbital geometry after isolated orbital floor fractures. Methods Standardized isolated orbital floor fractures were symmetrically created in 11 cadaver heads that provided 22 orbits. PDS foils with thicknesses of 0.25–0.5 mm were inserted. Computed tomography (CT) scans of the native, fractured, and reconstructed orbits were obtained, and orbital volume, orbital height, and foil bending were measured. Results Orbital volume and height significantly (p < 0.01) increased after the creation of isolated orbital floor fractures and significantly (p = 0.001) decreased with overcorrection of the orbital geometry after orbital floor reconstruction with PDS 0.25 mm or PDS 0.5 mm. The orbital geometry reconstruction rate did not differ significantly with respect to foil thickness. However, compared to PDS 0.5 mm, the use of PDS 0.25 mm resulted in quantitatively higher reconstructive accuracy and a restored orbital volume that did not significantly differ from the initial volume. Conclusion Orbital floors subjected to isolated fractures were successfully reconstructed using PDS regardless of foil thickness, with overcorrection of the orbital geometry. Due to its lower flexural stiffness, PDS 0.25 mm appeared to provide more accurate orbital geometry reconstruction than PDS 0.5 mm, although no significant difference in reconstructive accuracy between PDS 0.25 mm and PDS 0.5 mm was observed in this cadaveric study.
