“…Some of these tissues are limited in quantity and have a variable absorption range with time. Absorption is non-predictable and late enophthalmos potential are the arguments more criticized with the use of autologous materials, particularly bone grafts and a cartilage grafts [23].…”

“…Advantages represented are: good infection resistance, substitution for host bone, absence of rejection risk and low extrusion risk. However reabsorption and consequent volume reduction is the main enquiry after some time [23].Actually, skull bone seems to be the best option for orbital wall reconstruction, but iliac bone is still the preferred location.…”

Introduction: Several treatment options are available for the optimal treatment for orbital fractures, depending on aesthetic and functional results after orbital wall reconstruction. The objective of this study is to compare the effect and safety of large orbital fl oor fractures with titanium mesh combined with poly-L-lactic acid/polyglycolic acid copolymer implants (Lactosorb®) vs. autologous costochondral graft. A wide range of permanent and biodegradable materials have been used successfully for orbital fl oor reconstruction, however they present with disadvantages for reconstruction of large defects, even if combined. Results: Follow up of 21 patients (12 weeks) 17 male, 4 female, ages 22-63 was made. Enophthalmos, main objective of this study, was identifi ed with statistical signifi cance presenting 0% (n=0) post-op Group B patients and 30% (n=3) for Group A (p=0.049). Statistical signifi cance was found referring to inpatient days between two groups being less for costochondral reconstruction patients (p=0.02). No pain in patients undergoing alloplastic surgery. An interesting result was that donor area analogue pain scale for costochondral graft was 2.9/10. Patients and Methods Conclusion:Surgical outcome and complications where evaluated comparing different materials for orbital fl oor reconstruction. Costochondral graft is a suitable choice when orbital reconstruction is indicated.

The technique of guided tissue regeneration (GTR) has evolved over recent years in an attempt to achieve periodontal tissue regeneration by the use of a barrier membrane. However, there are significant limitations in the currently available membranes and overall outcomes may be limited. A degradable composite material was investigated as a potential GTR membrane material. Polylactic acid (PLA) and nano-hydroxyapatite (nHA) composite was analysed as a potential GTR membrane material. Its bioactive potential and suitability as carrier system for growth factors were assessed. The effect of nHA concentrations and the addition of platelet derived growth factor (PDGF) on osteoblast proliferation and differentiation was investigated. The bioactivity was dependent on the nHA concentration in the films, with more apatite deposited on films containing higher nHA content. Osteoblasts proliferated well on samples containing low nHA content and differentiated on films with higher nHA content. The composite films were able to deliver PDGF and cell proliferation increased on samples that were pre-absorbed with the growth factor. nHA-PLA composite films are able to deliver active PDGF. In addition the bioactivity and cell differentiation was higher on films containing more nHA. The use of a nHA-PLA composite material containing a high concentration of nHA may be a useful material for GTR membrane as it will not only act as a barrier, but may also be able to enhance bone regeneration by delivery of biologically active molecules.
