Mandibular defects due to surgical resection of pathologies are common challenges for maxillofacial surgeons. In some clinical situations, alteration or combination of different surgical procedures is needed to reduce the size of bony defects and improve the success rate of bone grafts. In the current study, an 18-year-old female with a pathological lesion (ameloblastoma) in the mandible is presented. After tumor resection, bony defect reconstruction with autogenous bone graft was combined with a mandibular setback to facilitate the procedure. In this case, the simultaneous combination of orthognathic mandibular setback movement with tumor resection in a single surgical session helped to reduce the bony defect size. The adoption of this approach led to a decrease in the volume of graft harvesting and improved the success rate of the grafting procedure.
因手术切除病变导致的下颌骨缺损是颌面外科医生面临的常见挑战。在某些临床情况下，需要改变或联合不同的手术操作以减小骨缺损的大小并提高骨移植的成功率。在本研究中，介绍了一名18岁患有下颌骨病理性病变（成釉细胞瘤）的女性。肿瘤切除后，自体骨移植进行骨缺损重建并联合下颌后缩以利于手术操作。在该病例中，在单次手术中同时进行正颌下颌后缩运动与肿瘤切除有助于减小骨缺损的大小。采用这种方法减少了移植骨采集的体积并提高了移植手术的成功率。
