Vascularized free flaps have become the gold standard in reconstructing large segmental mandibular defects; however, even when bony union and soft-tissue coverage is achieved, insufficient bone stock and altered facial contour can create functional and cosmetic problems for the patient. There have been limited case reports on the use of secondary distraction osteogenesis to address these issues. The authors report a case of bilateral mandibular distraction of deep circumflex iliac artery free flaps, used for mandibular reconstruction after total mandibulectomy for treatment of osteosarcoma. Performed for reasons of retrognathia and facilitation of dental prosthetic rehabilitation, this is the first case of bilateral horizontal distraction osteogenesis of deep circumflex iliac artery free flaps reported in the literature.
带血管蒂游离皮瓣已成为修复下颌骨大段缺损的金标准；然而，即使实现了骨愈合和软组织覆盖，骨量不足和面部轮廓改变仍会给患者带来功能和美容问题。关于使用二期牵张成骨来解决这些问题的病例报告有限。作者报告了一例双侧髂腹股沟深动脉游离皮瓣下颌骨牵张的病例，该皮瓣用于骨肉瘤全下颌骨切除术后的下颌骨重建。出于下颌后缩和便于牙修复康复的原因进行了该手术，这是文献中报道的首例双侧髂腹股沟深动脉游离皮瓣水平牵张成骨病例。
