The surgical goal for reduction of maxillofacial fracture has been focused on the reconstruction of facial buttresses. If there is fracture-displacement at non-buttress area, it close observation used to be the choice of treatment. It is not easy to have access to the posterior part of maxilla with conventional approach. But with the endoscopic sinus surgery technique, posterior wall of maxillary sinus is easily approachable and can be manipulated. This report presents a case of a 38-year-old male with isolated posterior wall of maxillary sinus fracture. Inward comminuted fracture-displacement of the posterior wall of maxillary sinus with retroantral fat and soft tissue was herniated into the maxillary sinus and extruded out through the natural ostium of maxillary sinus. Using endoscopic approach and Foley catheter inflation, the maxillary sinus posterior wall was successfully repaired without complications. This report thus suggests endoscopic approach with the Foley catheter for the posterior maxillary sinus wall fracture.
