title: Orbital floor implant migration across the ethmoidal sinuses and nasal septum.
abstract: OBJECTIVE
  To report an unusual case of orbital floor implant migration across the ethmoidal sinuses and nasal septum.
  
  
  METHODS
  Case report. A 61-year-old woman with a history of right orbital floor fracture repair 25 years earlier is described.
  
  
  RESULTS
  The patient presented with sinus congestion and difficulty breathing through the right nostril. Computed tomographic scan disclosed medial migration of the right orbital floor implant across the ethmoidal sinuses and nasal septum. The patient underwent transorbital and transnasal endoscopic surgery with removal of the implant.
  
  
  CONCLUSIONS
  When an alloplastic orbital floor implant is required, size and fixation of the implant are important. Late paranasal sinus or nasal airway problems may be sequelae, and the possibility of implant migration should be considered.
