The aim of this retrospective study was to analyse the outcome of 44 cases of vertical alveolar distraction osteogenesis (ADO) and to investigate the complications, precautions, and treatment associated with ADO. The 44 alveolar distractions were performed on 40 patients. Extraosseous distraction was used in all cases. Complications associated with the intraoperative, postoperative, distraction, and consolidation periods were recorded and evaluated. Intraoperative complications were noted in two patients (4.5%) where fracture of the basal bone was evident. Three (6.8%) complications were recorded postoperatively, and 12 (27.3%) complications were recorded during the activation period. During the consolidation period, 4.5% of the patients (n = 2) were affected. The total prevalence of complications was 43.2% (n = 19), and the success rate of the ADO was 95.5%. Most complications occurred in the anterior mandibular region. Although complications associated with vertical ADO were not rare, the use of this procedure for maxillofacial defects results in satisfactory outcomes. Early diagnosis and management of related complications are crucial for increasing the success rate of ADO procedures.
本回顾性研究旨在分析 44 例垂直牙槽骨牵张成骨（ADO）的结果，并探讨与 ADO 相关的并发症、预防措施和治疗方法。44 例牙槽骨牵张术在 40 例患者中进行。所有病例均采用骨外牵张。记录并评估术中、术后、牵张和巩固期与并发症相关的注意事项。两名患者（4.5%）术中出现基底部骨折，三名患者（6.8%）术后出现并发症，12 名患者（27.3%）在激活期出现并发症。在巩固期，4.5%的患者（n=2）受到影响。总的并发症发生率为 43.2%（n=19），ADO 的成功率为 95.5%。大多数并发症发生在前下颌区域。尽管垂直 ADO 相关并发症并不少见，但该手术用于颌面缺损可获得满意的效果。早期诊断和处理相关并发症对于提高 ADO 成功率至关重要。
