3D打印技术个性化定制瘢痕患者颈部功能支架的应用研究

Research on the application of 3D printing technology in personalized customization of neck functional stents for scar patients

目的探讨3D打印技术个性化定制瘢痕患者颈部功能支架的应用效果。方法选取2021年3月至2021年8月在我院进行颈部瘢痕治疗的患者43例,随机分为两组,在常规抗瘢痕药物治疗基础上,对照组(n=18)使用常规尺寸的颈托进行压力治疗,观察组(n=25)借助3D打印技术个性化制作颈部功能支架进行压力治疗。随访12个月,通过温哥华瘢痕评价量表(Vancouver scar scale,VSS)以及患者和观察者瘢痕评价量表(Patient and observer scar assessment scale,POSAS)进行评估,统计两组患者治疗前后相关数据,并进行统计学分析。结果观察组达到目标压力值的时间显著短于对照组(P<0.05);VSS评分各项指标均优于对照组(P<0.05);POSAS评分多项指标均优于对照组(P<0.05)。结论3D打印技术个性化定制瘢痕患者颈部功能支架,有利于患者维持稳定的压力治疗效果,改善瘢痕治疗疗效。

Objective To explore the application effect of 3D printing technology in personalized customization of neck functional stents for scar patients.Methods Fifty patients who underwent neck scar treatment in our hospital from March 2021 to August 2021 were selected and randomly divided into two groups according to the random number table method.On the basis of conventional anti-scar drug treatment,the control group was treated with a conventional size neck brace for pressure treatment,and the observation group was treated with a personalized neck functional stent made by 3D printing technology for pressure treatment.The patients were followed up for 12 months and assessed by the Vancouver Scar Scale(VSS)and the Patient and Observer Scar Assessment Scale(POSAS).Results A total of 43 patients completed the whole course of treatment.The time for the observation group to reach the target pressure value was significantly shorter than the control group(P<0.05);All indicators of VSS scores were better than the control group(P<0.05);Multiple indicators of POSAS scores were better than the control group(P<0.05).Conclusion Implementing 3D printing technology to customize personalized functional stents for neck scar patients is beneficial for maintaining stable pressure treatment effects and improving scar treatment efficacy.
