title: Options in orbital floor reconstruction in blowout fractures: a review of ten cases.
abstract: OBJECTIVE
  The purpose of this case series was to assess the aesthetic and functional outcome of orbital floor reconstruction performed with calvarial bone graft, titanium mesh or prolene mesh.
  
  
  METHODS
  Ten cases of orbital blowout fractures treated at our centre from October 2006 to July 2008 were considered for this study. Clinical examination, patient satisfaction and radiographic investigations were used to assess repaired fractures.
  
  
  RESULTS
  Prolene mesh was used in four cases, titanium mesh was used in four cases and calvarial graft used in two cases. Nine patients had significant improvement in their esthetic appearance. Symmetry was restored in all cases. All ten cases had a noticeable improvement in the function. Of total ten cases six had diplopia, three recovered completely during the six months after the surgery. Three cases showed improvement later. All ten cases with enopthalmos recovered completely. Of the nine patients with infraorbital numbness, all recovered completely during the six months following surgery. One patient where the reconstruction was done with calvarial bone graft showed mild discrepancy in the ocular level.
  
  
  CONCLUSIONS
  For small, linear defects measuring less than 2cm with enopthalmos and restricted ocular movements, prolene mesh (four cases) was used. For larger defects and impure blowout fractures involving the infraorbital rim, calvarial graft (two cases) or titanium mesh (four cases) was used. The outcome of surgery with all three materials was satisfactory. No postoperative complications were seen except for mild hypoglobus in a case reconstructed with calvarial graft. All three materials, calvarial graft, titanium mesh, prolene mesh, have the potential to be useful reconstructive materials in orbital floor blowout fractures.
