Reconstruction of a maxillary defect using the remnant bone of mandibular angle ostectomy.

The buttress is the cornerstone of the midface both functionally and aesthetically. Therefore, fracture of the buttress requires surgery. A patient wanted cosmetic surgery simultaneously with a reduction of facial bone fracture. To achieve this, we reconstructed the defect of the maxillary buttress using the remnant bone of the mandible angle ostectomy. A 27-year-old man presented with a left maxilla fracture and defect at the maxillary buttress. Since the patient was considering cosmetic surgery to alter his square face, we planned a mandibular angle ostectomy and used the remnant bone as an onlay bone graft for maxillary reconstruction. There was no complication and the patient was satisfied with both the functional and aesthetical look of the reconstructive surgery. We reconstructed the defect of the maxillary buttress successfully using the remnant bone of the mandible angle ostectomy. Although this technique cannot be applied to every patient, reconstruction of facial bone defects with the remnant bone of the mandibular angle ostectomy may be a potential option in some cases.
