title: Intra-operative navigation for orbital reconstruction to correct diplopia and enophthalmos with endoscopic assisted technique: first case report in Thailand.
abstract: OBJECTIVE
  In an orbital fracture involving diplopia, enophthalmos is a major problem to be corrected because ofsoft tissue swelling and limited incision, which causes inaccurate restoration oforbital anatomy and reestablishing orbital volume. Pre-operative computerized planning combined with intra-operative navigation and endoscopy are used to create the accurate anatomical orbital position and effectively correct the posttraumatic diplopia and enophthalmos.
  
  
  METHODS
  An 18-year-old Thai male with diplopia and enophthalmospresented aposttraumatic left orbital fracture two months prior Three-dimensional CTscan of the facial bone confirmed the fracture. The patient required surgical treatment for correction of the orbital fracture. The intra-operative navigator and endoscopy-assisted technique were used. Pre- and post-operative pictures were compared, indicated the successful correction of enophthalmos and clinical correction of diplopia.
  
  
  CONCLUSIONS
  Intra-operative navigator combined with endoscopy-assisted technique were a new surgical procedure that could correct the orbital deformity problem involving enophthalmos and diplopia more effective.
