Mid-secondary alveolar cleft repair performed at ages 9-12, in the mixed dentition stage, prior to eruption of the permanent canine, is generally accepted as the ideal time for residual alveolar cleft closure in cleft lip and palate cases with a cleft alveolus.
In our study, four cases of mid-secondary and five cases of late-secondary alveolar cleft grafting were carried out using iliac crest corticocancellous bone graft. Clinical defect closure and radiographic bone fill were compared.
All the nine cases performed in the two different age groups showed excellent results, clinically, with complete closure of the cleft defect and achievement of continuity of the dental arches. One case was planned for a two-stage procedure owing to the large bilateral maxillary defects. Good bone fill was visualized radiographically in all nine cases.
Precise timing for undertaking alveolar cleft repair may not be all that crucial for a successful alveolar cleft grafting procedure.
在9至12岁、混合牙列期、恒牙尖牙萌出之前进行的中二期牙槽嵴裂修复,通常被认为是唇腭裂合并牙槽嵴裂病例中残余牙槽嵴裂闭合的理想时机。
在我们的研究中,使用髂骨皮质松质骨移植对4例中二期和5例晚二期牙槽嵴裂进行了植骨。比较了临床缺损闭合情况和影像学骨填充情况。
在两个不同年龄组进行的所有9例手术临床效果均极佳,裂隙缺损完全闭合,牙弓连续性恢复。由于双侧上颌骨缺损较大,1例计划进行两期手术。所有9例影像学检查均显示骨填充良好。
对于成功的牙槽嵴裂植骨手术而言,进行牙槽嵴裂修复的确切时机可能并非那么关键。
