Reconstructing segmental mandibular defects in children of deciduous dentition is a challenge. The authors treated a 23-month-old girl with a segmental mandibular defect secondary to tumour resection. Considering the unpredictable negative impacts of the autogenous bone grafting method on the musculoskeletal system of the donor sites, which was growing rapidly at this age, the authors applied transport disc distraction osteogenesis (TDDO) to reconstruct the mandible discontinuity. To the best of the authors' knowledge, this is the first time TDDO has been used for mandible reconstruction in such a young patient with deciduous dentition. Aesthetics and function were restored satisfactorily at the end of treatment. The facial appearance and occlusion were stable through the 35 month follow-up, possibly due to the growth of the regenerated bone parallel with the rest of the maxillofacial skeleton. The satisfactory reconstruction also contributed to the patient's physical and psychological development. The success of mandible reconstruction with TDDO in this study casts new light on the management of segmental mandibular defect in children with deciduous dentition.
重建儿童乳牙期的下颌骨节段性缺损是一项挑战。作者治疗了一名 23 个月大的女孩，她因肿瘤切除而出现下颌骨节段性缺损。考虑到自体骨移植方法对供区骨骼系统的不可预测的负面影响，而在这个年龄段，供区骨骼系统生长迅速，作者应用了牵引骨段延长术（TDDO）来重建下颌骨连续性。据作者所知，这是 TDDO 首次应用于如此年幼的乳牙期患者的下颌骨重建。治疗结束时，美观和功能得到了满意的恢复。经过 35 个月的随访，面部外观和咬合稳定，这可能是由于再生骨与颌面部其余骨骼平行生长。满意的重建也有助于患者的身体和心理发展。本研究中 TDDO 成功重建下颌骨为乳牙期下颌骨节段性缺损的治疗提供了新的思路。
