BACKGROUND
The goal of this study was to evaluate prospectively the use of a transpalatal distractor for surgically assisted rapid palatal distraction osteogenesis in the treatment of severe unilateral maxillary constriction of patients with cleft lip and palate following alveolar bone grafting.
METHODS
The authors analyzed the clinical and radiographic data of eight patients with unilateral cleft lip and palate. Follow-up examinations were performed at 1, 3, 6, and 12 months.
RESULTS
All of the patients had satisfactory palatal expansion and correction of the dental crossbite without major complications. None of the children in this study were noncompliant with the prescribed duration of the active distraction period.
CONCLUSIONS
Surgically assisted rapid palatal distraction osteogenesis using a transpalatal distractor results in a high rate of success in correcting maxillary transverse width discrepancies and dental crossbite and offers a harmonious maxillary arch shape in patients with unilateral cleft lip and palate.
背景
本研究的目的是前瞻性评估经腭中缝牵张器在牙槽骨植骨后唇腭裂患者严重单侧上颌缩窄的外科辅助快速腭中缝牵张成骨治疗中的应用。
方法
作者分析了8名单侧唇腭裂患者的临床和影像学资料。在1、3、6和12个月时进行随访检查。
结果
所有患者腭部均获得满意扩宽，牙反合得以矫正，且无重大并发症。本研究中所有儿童均未违反规定的主动牵张期时长。
结论
使用经腭中缝牵张器进行外科辅助快速腭中缝牵张成骨，在矫正单侧唇腭裂患者上颌横向宽度差异和牙反合方面成功率很高，并能提供协调的上颌牙弓形态。
