目的 探讨数字化三维成形技术,在复杂性颌骨凹陷畸形修复中的应用效果。方法 自2014年1月至2016年5月,应用数字化三维成形技术,修复12例复杂性颌骨凹陷畸形,回顾性分析其手术方法、手术时机及预后。结果应用数字化三维成形技术修复复杂性颌骨凹陷畸形,提高了颌骨修补后与原来颌骨的一致性,且手术时间平均比传统方法缩短2 h。随访未发现有补体移位、外露或排异等严重并发症。结论 应用数字化三维成形技术修复复杂性颌骨凹陷畸形,可明显提高颌骨修补后与原来颌骨形状的一致性,同时缩短手术时间,降低手术风险,值得临床推广应用。
Objective To explore the efficiency of digital three-dimensional?molding technology for the repair of the complex maxillofacial depression. Methods From January 2014 to May 2016, 12 cases with complex maxillofacial depression were treated using digital three-dimensional?molding technology. The surgical methods, timing and prognosis were analyzed retrospectively. Results Using the digital three-dimensional molding technology, the conformity has been greatly improved. 12 patients all regained their original shapes of maxillofacial bones. At the same time, the average operation time reduced by two hours. Up to now, no serious complications were observed, like shift, leakage or rejection of the complement. Conclusion Repairing maxillofacial depression with the technique of three-dimension shaping can obviously improve the conformity and reduce operation time and risk, which is worth popularization and application.
