Five adult patients with gunshot wound defect underwent bilateral mandibular lengthening by an extraoral device. All patients presented with interrupting mandibular defect of 50 to 100 mm. Distraction of bone fragments led to mandibular reconstruction without bone grafting and simultaneous expansion of soft tissues, avoiding free or pedicled myocutaneous flaps for soft tissue reconstruction of the lower third of the face. Mandibular distraction also recreated the alveolar ridge with its attached mucosa which is equivalent to the gingiva. It can be used for dental rehabilitation by osseointegrated implants. Avoiding the morbidity and functional problems of classical flaps, mandibular distraction accelerates facial reconstruction, and social reinsertion of these patients.
5例成年下颌骨枪伤缺损患者采用口外装置进行双侧下颌骨延长。所有患者均表现为下颌骨50至100毫米的连续性缺损。骨块牵张实现了下颌骨的重建，无需植骨，同时软组织也得到扩张，避免了使用游离或带蒂肌皮瓣进行面部下三分之一的软组织重建。下颌骨牵张还重建了带有附着黏膜（等同于牙龈）的牙槽嵴。它可用于种植体植入的牙齿修复。下颌骨牵张避免了传统皮瓣的相关并发症和功能问题，加速了面部重建以及这些患者重新融入社会的进程。
