In daily clinical practice, quite a few cases with maxillofacial trauma are encountered, where not only lower-face fractures but also middle-face fractures are found. As a result, various functional disorders are encountered, among which we often find cases accompanied by nasal bone fracture or orbital fracture. In some cases with orbital fracture, limitation of supraduction due to inferior rectus muscle injury or diplopia is observed. In cases of orbital fracture with bone defect, where the abovementioned clinical symptoms are severe, bone grafting is required in cooperation with ophthalmologists, otorhinolaryngologists or plastic surgeons. However, in cases with fewer symptoms, high priority should be put on conservative treatment. Between May 2010 and April 2014, we experienced cases of reducing orbital fracture accompanied by maxillary fracture with the antral balloon technique. This paper introduces the technique and discusses its treatment results, with a review of the literature.
