摘要目的 评价三维重建及模拟技术在鼻成形术中的应用价值,为术前指导、术中实施提供依据.方法 2016年10月至2017年3月,对赣州俪人医疗美容门诊部25例女性(年龄18～39岁,平均26岁)鼻美容就医者进行三维扫描.与美容就医者术前沟通后获得双方认可的3D术后效果,模拟术后鼻尖突出度、鼻尖表现点,鼻背高度、弧度等.经软件测量及3D打印模型指导手术.结果 25例美容就医者均获得直观、精确的三维重建图形及模拟手术方案.术后随访,23例对效果满意;2例出现鼻尖外形下旋、退缩,给予调整后获满意效果.结论 三维重建及模拟技术有助于提高鼻成形精度,是鼻成形的良好辅助手段.

abstractsObjective To provide useful reference for the pre-operative design and operation by 3D reconstruction and simulation techniques in rhinoplasty.Methods From October 2016 to March 2017,the laser scanning and 3D reconstruction were performed on 25 patients before operations.The facial morphology and the simulated effect were ontained.All patients were female and they were 18 to 39 years old.The average age was 26 years old.The outline and form were normal.We discussed with patients to confirm the ideal nasal 3D simulated effect.In the process of operation,we were guided by the data of soft measures and 3D printing model.Results Among 25 patients who werefollowed up postoperatively.We got intuitive,accurate 3D reconstruction graphs and simulated surgery procedures in all cases.Being applied to actual surgery procedure,23 patients were satisfactory with postoperational results.Two patient's nasal tip dropped.We were satisfied with the results after repair.Conclusions 3D reconstruction and simulation techniques improve surgical precision and operation planning selection,which is a good aided method in rhinoplasty.
